We also have Firepower running on it, which allows us to use it for content filtering.,The ASA has been around forever, and has been proven to be a great firewall solution. ASAs are very versatile, running everything from VPNs and ACLs to content filtering. Running them in tangent with other Cisco routing solutions allows for a very diverse and secure setup.,There are two types of technologists: ones who speak Cisco, and ones who don't. The ASA is no different from any Cisco device, in that it comes with a learning curve. These aren't consumer products, and they come with an enterprise price tag. Like many vendors, Cisco uses a java based admin consoles. This is its own special form of torture.,9,The most positive effect the ASA has had on our org is the reliability and flexibility from adding Firepower. The main negative (besides cost) is occasionally needing a consultant to wrap our head around getting the ASA to do what we want. But this is more Cisco than the ASA, and we have a uniquely complex environment.,Cisco Unified Computing System Manager, Ansible, AvamarDecent Firewall at a decent price point.We've deployed ASAs throughout our multiple datacenters and we also use them as onsite edge devices at many of our client sites. We're using them for NATing client devices as well as applying stringent ACLs to control what clients can access on our networks and what we can access on a clients network.,HA NAT ACLS FAILOVER HA VPN,Maybe this has changed, but our ASAs were/are limited ACLs based on Object-Groups/IPs/Ports versus our Palo Altos offer application layer inspection to make sure that traffic traversing the firewall on a specific well known port such as 22 is actually SSH traffic or that traffic on port 80/443 is actually HTTP/HTTPS.,8,Allow us to keep our clients and our business secure. Allow us to use NAT IPs for client side devices so that we're not having to do as much crazy routing or validating that clients aren't using overlapping address space.

Very good support and attention from the company and its associates. Constant security updates and functionalities. Robust and reliable equipment, great flexibility in configurations and fully scalable in power and functionalities to the need of the company.,Well, the price is always an important factor with this brand, but I am witnessing that it is worth what it costs, although the ROI is generally not as good as the investors would like it to be. The virtual appliance still consumes too many resources compared to similar ones and I have to assign physical network cards to get an adequate performance when implementing it.,9,The ROI is generally not as good as the investors would like it to be.

We also recommend and sell ASA units to customers for use in their networks. Lastly, we recommend and sell ASA units to customers that we host for various applications, so that they can have access to "cloud" based apps but also be as secure as possible in the access thereof.,ASA units provide firewall capabilities that would normally be found in much more expensive equipment ASA units provide POE capability for use with VOIP phones or other equipment. ASA units connect outside internet to inside networks and VPN's with very little overhead and no loss of signal speed. ASA units allow me to run a wireless access point in parallel so that both wired and wireless devices can share one DHCP scope which makes it easier to manage and maintain. ASA units make use of ASDM but also the Cisco standard CLI which makes it easier to train engineers to manage and have ease of deployment using config templates.,In the ASA5506, unlike its predecessor, there are no switched Ethernet ports. Adding that feature would be helpful and save the cost of the additional switch that must be purchased. The real time log viewer is not that great, it's not 100% reliable, its explanations are often a bit too technical, the filter could use some enhancement The ASDM interface as a whole being java is not good. Java has become a nightmare due to poor backwards compatibility and cliff-facing certificate requirements between versions, so java versions for administrators become a nightmare to manage for what should be simple changes,10,Deploying Cisco ASA allows us to offer firewall, LAN, WAN and Wifi to businesses, with low overhead costs, low maintenance and of course great TAC support Using ASA units keeps within the solid industry leading Cisco standards while keeping costs down We are able to use known tools for deployment and troubleshooting without the need for training on additional interfaces.,Palo Alto Panorama,Palo Alto Networks GlobalProtect Mobile Security Manager, Banyan, Palo Alto Networks Next-Generation Firewalls - PA SeriesCisco ASA met all our network firewall needs.Cisco ASA is our main firewall for our site. It is also the VPN termination point for our LAN to LAN VPNs and Remote Access VPNs. It has solved the problem of needing a firewall for cyber security. It has also solved the problem of employees needing remote access into the corporate network.,Cisco ASA is very configurable. Cisco ASA has a lot of features. Cisco ASA is robust. Failing almost never. Cisco ASA can integrate with many other Cisco security solutions.,There is a learning curve for Cisco ASA. A lot of what can be done, initially, needs to be done at the command line interface. Organizing all the firewall rules can be a little daunting with the current UI.,9,Cisco ASA has met all the compliance requirements we have for a network firewall which has had a positive impact on our business objectives. Cisco ASA allows all our users to remote access our network which has had a positive influence on meeting the business need to allow remote access. The integration features of the Cisco ASA has allowed us to continue to secure our network with state of the art security solutions.,Palo Alto Networks Next-Generation Firewalls - PA Series,Darktrace, Microsoft System Center Configuration Manager, Microsoft Office 2016Good classic firewall, but not a next gen winner.We deploy the CIsco ASA 5505 & 5506 on over 250 customers' sites to protect the local LAN and establish a site-to-site VPN to our datacenter from which we host the customer applications. On our datacenter, we use an HA pair of ASA 5585s to produce redundant internet access and NAT all traffic.,Easy to configure with a template and CLI. TACACS command authorization and accounting is must have for compliance. Good SNMP monitoring options. Well developed and very compatible firewall OS.,The 'Next Generation' options feel bolted on and the performance is underwhelming. Impact of enabling the Firepower Inspection is too big. Both response time and throughput suffered horribly.,8,Provided a solid performance on the LAN edges of both our customer sites and our datacenters. Hardly any hardware failures.,Cherwell Service ManagementOur experiences with Cisco ASA firewalls.We have about a dozen Cisco ASA models deployed from 5505-5545. We use them to separate traffic between internal organizations, for DMZ, and for VPN (both IPSEC and SSL). The problems these units address are two-fold: to protect our internal network from foreign networks that we have no control over, and to protect the foreign networks from the chance of getting infected by something on our internal network.,When sized appropriately, it can handle demanding traffic well. Cisco is pretty good about putting out security-related updates so we can rest assured that the networks can be as safe as possible. The hardware is very reliable and I don't recall any hardware related issues in the 5+ years of using them. Software upgrades are smooth and I would recommend getting Cisco support assistance for them to review your current configuration and have them advise which stable and secure version you should move to. They may provide additional commands to enter prior to upgrading if you are moving from a very old version of the software.,Reporting, especially for VPN functionality, could use some improvements to be able to pinpoint when particular users log in/out. The JAVA-based GUI could use some modernization. I currently have to use an older version of JAVA JRE to run the ASDM. Some of the licensing structure could use some simplifying. You really have to size the appliance for growth before purchasing the initial license. The bare-bones license doesn't provide much flexibility.,8,The ASAs have helped us meet compliance regulations in terms of security so that saved us from getting fined/decertified. The flexibility of ASAs have allowed us to standardize on a common platform for the various use cases we have. This allowed us to not have to get other brands which the administrators would have to become familiar with. The long support cycle with timely software updates to address security threats has also been positive on ROI.,,Proofpoint Email Security and Protection, Microsoft Exchange, CentOSThe Swiss Army Knife of FirewallsCisco ASA provides many security and networking features. These include VPN (Virtual Private Network) capabilities, traffic prioritization, DHCP, Firewall protection of our network, routing, and many more. These allow our business to operate securely, give remote employees easy access to our on-network services, shape our traffic to allow critical services (such as VOIP) to operate at higher priority, and generally give us fine-tuned control over the operation and management of our network and how it interacts with the outside world.,Performance Reliability Security Configurability/Customization,User Interface Ease of use Setup,9,Improved efficiency for remote work Improved security - much lower risk in day-to-day operations Increased management cost of network/infrastructure,SonicWall TZ,Ubuntu Linux, MySQLCisco ASA Rocks!We use Cisco ASA at the headquarters and the sites to build our cross-network and edge gateway. Like always, Cisco rocks with their hardware, no issues at all. Even better now with the Cloud services, Cisco pushes down updates to the ASA blocking potential threads.,Rock solid when it comes to VPN Site-to-Site. Excellent Firewall functionalities. HA capabilities, it never fails.,It would be better if Cisco continues improving the ASDM for new administrators starting their networking career. It would be great if Cisco builds a management web interface like they do for small business products.,10,Overall, Cisco ASA rocks, it never fails. 100% up time.,Cisco ASA - Aging tech no longer a leader in the firewall marketThe Cisco ASA platform has a niche place in our infrastructure. It is a decent stateful firewall but lacks features and functionality for changes in network security, segmentation, and user-based access controls. It is a good SSL VPN technology but that is about the only feature on the ASA platform that is widely used. As technology advances, it appears that Cisco has forgotten about the ASA.,SSL VPN Authentication tiering,User-based access control functionality Better logging User interface,5,ASA has good ROI for SSL VPN Negative ROI as a firewall platform Negative ROI for logging,Palo Alto Networks Next-Generation Firewalls - PA Series and Fortinet FortiGateCisco ASA using VPN phonesWe use Cisco ASA for our remote phone VPN users. It’s being used primarily by our attorneys that sometimes work at home. It allows our users to have a home office and work with our clients and have them accessible for conferences and gives our users flexibility to conduct business outside the office.,Allows remote phones to VPN and connect to the phone system It’s secure and allows TLS 1.2 encryption It’s more reliable to use a physical phone than soft clients e.g. Jabber,Since we use it for VPN phones the devices need to be configured internally before we deploy them in the field. I have to be able to update the VPN profiles remotely.,10,We use ASA for VPN phones and it allows our attorneys the flexibility to work with our clients.

The VPN functionality has improved the security of our network while providing our users multiple hardware options for accessing sensitive network resources with less risk.,SolarWinds IPAM, SolarWinds Network Configuration Manager, Concur ExpenseCISCO ASA: A SCALABLE & FUTURISTIC SCALABALE SECURE SOLUTIONCisco ASA is our main Perimeter firewall across the globe, routing all the internet traffic in and out of our infrastructure. It gives the secured way of filtering traffic as per our need. The best part of ASA is the support and trust of loyalty in last 10 years we just never have to reboot the device once also. Its credibility is amazing.,How we can manage: ASDM the GUI is so much easier to manage it even for a new guy also. Traffic handling capacity More secure and the different features it gives. Support from the TAC team or from the community manages to handle issues very efficiently.,I would say Cisco should concentrate more how they will move way the traditional IPS to a new sand-boxing kind of environment.,10,We already got most out of it.

I am not an expert on ASA by any means, but I have used several of the basic functions such as SSL VPN and configuring different VLANs for multiple devices. I only use the Command Line Interface, and never the ASDM which runs on a Java applet.,Customer support is Cisco's forte, and ASA is no exception. If you have issues, they are available 24/7 to help you resolve them. Longevity. I still have a 5510 running that has been running for over 3 years without a reboot with zero issues.

We have been using Cisco ASA for many years securing our users when accessing the internet and securing our network from users on the internet accessing websites we host. We also use Cisco ASA for VPN access. We have multiple site to site VPNs along with Cisco AnyConnect VPN for users accessing corporate resources when out of the office.,The Cisco AnyConnect VPN is used by our users and is a very easy and secure method for employees to access corporate resources. The Cisco ASA 5585 can be configured in a cluster for larger throughput and high availability. When purchased with FirePOWER the Cisco ASA can be configured to inspect the application layer of the packets for better threat detection.,The Cisco ASA can be configured via command line and with a GUI interface. The GUI interface needs work. It uses Java and depending on Java version you can have issues launching the application. The Cisco ASA needs better logging for troubleshooting. When trying to narrow down an issue the logging needs more information. Licensing can be difficult to understand and there are many options. Make sure you fully understand your needs before ordering.,8,Once fully configured and implemented the product is very solid and provides great security.

  • ASDM ease-of-use could be improved.
  • Upgrade/migration from previous versions and the way objects are named.
  • Bring in more support contexts in the default licensing.
  • Bring in more support for SSL VPN connections in the default licensing.
Cisco ASA is well suited for customer scenarios where a customer does not need or want next-gen features and only needs legacy firewalling functionality. Cisco ASA is less appropriate in situations where a customer requires next-gen features and network segmentation. In this scenario, a customer should investigate the option of Cisco Firepower appliances running the Firepower threat defense software.

We've deployed ASAs throughout our multiple datacenters and we also use them as onsite edge devices at many of our client sites. We're using them for NATing client devices as well as applying stringent ACLs to control what clients can access on our networks and what we can access on a clients network.
  • HA NAT
  • ACLS
  • FAILOVER
  • HA
  • VPN
  • Maybe this has changed, but our ASAs were/are limited ACLs based on Object-Groups/IPs/Ports versus our Palo Altos offer application layer inspection to make sure that traffic traversing the firewall on a specific well known port such as 22 is actually SSH traffic or that traffic on port 80/443 is actually HTTP/HTTPS.
They work fairly well for firewalling and tended to be lower cost than our Palo Altos. If you're looking for a decent firewall and cost is a concern I'd say ASAs are a decent option. If you'e looking for a more secure environment you might want to look at the Palo Altos in addition to or instead of the ASAs.

Cisco ASA is used to filter access to very specific networks that need isolation from the rest of the information system. Our requirements were to have a good level of security, along with enough flexibility so that we could address unpredictable changes in the feature set that the admins of those networks may demand in the future.
  • Manageability.
  • Deployment.
  • Security.
  • Set of features apart from simple stateful filtering.
  • Performance.
  • Clustering.
  • Scalability once setup if you don't go for clustering.
Cisco ASA is well suited for situations where you have a short set of rules but need many features that enhance the filtering. For instance, if you have to isolate a network within your information system, in order to give ownership of that specific network to another team, and still have a lot of flexibility on how you interact with that network and your main site network, this is one good way to go.
You can even give access to the other team for monitoring purposes and helping with debugs.

The Cisco ASA platform has become the standard which I use for most of my SOHO and enterprise setups. I most recently have used this as a buffer between an AWS environment and a production network, where it behaved flawlessly. A second use case was as a VPN concentrator to consolidate all client to site, and site to site VPN connectivity, where it again behaved admirably.
  • Top of the line crypto, and firepower inline makes threat management easy.
  • easy to set up vpn, now including tunnel interfaces!
  • SOLID infrastructure for client to site vpn with anyconnect
  • TCO is higher than most.
  • firepower integration into the appliance is straightforward but weak. Units often times cannot process the amount of traffic thrown at them.
  • Support can be painful to work with at times. Need more english speaking staff.
Places where this product is well suited -
* VPN Functionality - Client to Site/Site to Site
* Internet Edge Gateway - NAT/PAT providing internet access to staff/production networks
* Interior firewall - Network segmentation

We use it in several critical access and control points, both internal and external. With it we deploy the VPNs that interlace all our offices and authorized consultants for remote access.Together with other tools of the same brand, automated rules are established that allow a more effective control of cybersecurity inside and outside the company.

  • Excellent integration with several systems and equipment of other brands, as well as with the entire Cisco ecosystem.
  • Very good support and attention from the company and its associates. Constant security updates and functionalities.
  • Robust and reliable equipment, great flexibility in configurations and fully scalable in power and functionalities to the need of the company.
  • Well, the price is always an important factor with this brand, but I am witnessing that it is worth what it costs, although the ROI is generally not as good as the investors would like it to be.
  • The virtual appliance still consumes too many resources compared to similar ones and I have to assign physical network cards to get an adequate performance when implementing it.
Implementing an ASA is not advisable for a small business with a tight budget for IT. To get the juice you must be willing to invest in licenses and maintain the support contract to continue receiving updates. In the medium term you will be satisfied, but in the meantime I am sure that the finance manager is not going to be your best friend. Now, if you are looking for stability, performance, redundancy in communications, security at all levels and you want to keep all your branches properly interconnected, ASA is your smartest choice.

We use Cisco ASA units for internal remote users to remain connected to our network for access to applications, file shares and corporate email. We also recommend and sell ASA units to customers for use in their networks. Lastly, we recommend and sell ASA units to customers that we host for various applications, so that they can have access to "cloud" based apps but also be as secure as possible in the access thereof.
  • ASA units provide firewall capabilities that would normally be found in much more expensive equipment
  • ASA units provide POE capability for use with VOIP phones or other equipment.
  • ASA units connect outside internet to inside networks and VPN's with very little overhead and no loss of signal speed.
  • ASA units allow me to run a wireless access point in parallel so that both wired and wireless devices can share one DHCP scope which makes it easier to manage and maintain.
  • ASA units make use of ASDM but also the Cisco standard CLI which makes it easier to train engineers to manage and have ease of deployment using config templates.
  • In the ASA5506, unlike its predecessor, there are no switched Ethernet ports. Adding that feature would be helpful and save the cost of the additional switch that must be purchased.
  • The real time log viewer is not that great, it's not 100% reliable, its explanations are often a bit too technical, the filter could use some enhancement
  • The ASDM interface as a whole being java is not good. Java has become a nightmare due to poor backwards compatibility and cliff-facing certificate requirements between versions, so java versions for administrators become a nightmare to manage for what should be simple changes
We appreciate that there are a variety of ASA units for different sized networks. It is particularly well suited for businesses that have multiple small to medium sites that need internet protection and VPN connections at the same time. The added capability of wireless access makes the ASA in our opinions a great one-stop shop for network, firewall, and VPN.

Cisco ASA is our main firewall for our site. It is also the VPN termination point for our LAN to LAN VPNs and Remote Access VPNs. It has solved the problem of needing a firewall for cyber security. It has also solved the problem of employees needing remote access into the corporate network.
  • Cisco ASA is very configurable.
  • Cisco ASA has a lot of features.
  • Cisco ASA is robust. Failing almost never.
  • Cisco ASA can integrate with many other Cisco security solutions.
  • There is a learning curve for Cisco ASA.
  • A lot of what can be done, initially, needs to be done at the command line interface.
  • Organizing all the firewall rules can be a little daunting with the current UI.
Cisco ASA - we have integrated it with Cisco Firepower. Our Cisco ASA is an important part of our network infrastructure. When we need to implement a new firewall rule or edit an existing one the Cisco ASA UI makes this task easy. The Cisco ASA is well suited for any network firewall need.

We deploy the CIsco ASA 5505 & 5506 on over 250 customers' sites to protect the local LAN and establish a site-to-site VPN to our datacenter from which we host the customer applications. On our datacenter, we use an HA pair of ASA 5585s to produce redundant internet access and NAT all traffic.
  • Easy to configure with a template and CLI.
  • TACACS command authorization and accounting is must have for compliance.
  • Good SNMP monitoring options.
  • Well developed and very compatible firewall OS.
  • The 'Next Generation' options feel bolted on and the performance is underwhelming.
  • Impact of enabling the Firepower Inspection is too big. Both response time and throughput suffered horribly.
Excellent layer 1-4 firewall, HA works flawless, great performance for classic firewall.

For Next Gen features you had better look at the firepower threat defense devices, as the next generation features of ASA are not well integrated.

Our experiences with Cisco ASA firewalls.

Score 8 out of 10
Vetted Review

We have about a dozen Cisco ASA models deployed from 5505-5545. We use them to separate traffic between internal organizations, for DMZ, and for VPN (both IPSEC and SSL). The problems these units address are two-fold: to protect our internal network from foreign networks that we have no control over, and to protect the foreign networks from the chance of getting infected by something on our internal network.
  • When sized appropriately, it can handle demanding traffic well.
  • Cisco is pretty good about putting out security-related updates so we can rest assured that the networks can be as safe as possible.
  • The hardware is very reliable and I don't recall any hardware related issues in the 5+ years of using them.
  • Software upgrades are smooth and I would recommend getting Cisco support assistance for them to review your current configuration and have them advise which stable and secure version you should move to. They may provide additional commands to enter prior to upgrading if you are moving from a very old version of the software.
  • Reporting, especially for VPN functionality, could use some improvements to be able to pinpoint when particular users log in/out.
  • The JAVA-based GUI could use some modernization. I currently have to use an older version of JAVA JRE to run the ASDM.
  • Some of the licensing structure could use some simplifying. You really have to size the appliance for growth before purchasing the initial license. The bare-bones license doesn't provide much flexibility.
DMZ firewall, general internet browsing, VPN (SSL and IPSEC). ASA can handle many firewall rules without slowing down. Some of them also offer PoE on the switchports of the firewall, which is convenient for small home office installations. One of the features is a high availability configuration in an active/standby mode. You can upgrade the software without any downtime.

Cisco ASA provides many security and networking features. These include VPN (Virtual Private Network) capabilities, traffic prioritization, DHCP, Firewall protection of our network, routing, and many more. These allow our business to operate securely, give remote employees easy access to our on-network services, shape our traffic to allow critical services (such as VOIP) to operate at higher priority, and generally give us fine-tuned control over the operation and management of our network and how it interacts with the outside world.
  • Performance
  • Reliability
  • Security
  • Configurability/Customization
  • User Interface
  • Ease of use
  • Setup
You will want an IT expert who can assist with setup as well as day to day management. Certain VPN configurations may require additional licensing - make sure you know what your needs are and research costs accordingly. Licensing across the board should be researched carefully since it's not always clear with Cisco products. Ideally, have a Cisco expert research and quote a solution that meets your specific business needs.

We use Cisco ASA at the headquarters and the sites to build our cross-network and edge gateway. Like always, Cisco rocks with their hardware, no issues at all. Even better now with the Cloud services, Cisco pushes down updates to the ASA blocking potential threads.
  • Rock solid when it comes to VPN Site-to-Site.
  • Excellent Firewall functionalities.
  • HA capabilities, it never fails.
  • It would be better if Cisco continues improving the ASDM for new administrators starting their networking career.
  • It would be great if Cisco builds a management web interface like they do for small business products.
I don't know why an IT department would not consider a Cisco ASA.

Cisco ASA - Aging tech no longer a leader in the firewall market

Vetted Review

The Cisco ASA platform has a niche place in our infrastructure. It is a decent stateful firewall but lacks features and functionality for changes in network security, segmentation, and user-based access controls. It is a good SSL VPN technology but that is about the only feature on the ASA platform that is widely used. As technology advances, it appears that Cisco has forgotten about the ASA.
  • SSL VPN
  • Authentication tiering
  • User-based access control functionality
  • Better logging
  • User interface
The ASA platform really is only suitable for SSL VPN use cases that can't be solved by other means. Its time as an industry leading firewall has ended. Cisco missed the boat with updates to the ASA platform and has not kept up with firewall trends. They tried to add bolt on functionality but the ASA really is not a security appliance and is one of the last stateful firewalls left that only has vanilla functionality.

Cisco ASA using VPN phones

We use Cisco ASA for our remote phone VPN users. It’s being used primarily by our attorneys that sometimes work at home. It allows our users to have a home office and work with our clients and have them accessible for conferences and gives our users flexibility to conduct business outside the office.
  • Allows remote phones to VPN and connect to the phone system
  • It’s secure and allows TLS 1.2 encryption
  • It’s more reliable to use a physical phone than soft clients e.g. Jabber
  • Since we use it for VPN phones the devices need to be configured internally before we deploy them in the field. I have to be able to update the VPN profiles remotely.
We use ASA for CisVPNvpn phones and it handles that task well. For enterprise wide firewall we use Palo Alto equipment.

  • Pricing is a little high
The ASA has been a fantastic VPN device as well as firewall with integrated services. Protection features with Firepower provides advanced malware protection with an active license. I haven’t experienced any situations where the device is less appropriate.

Cisco ASA is our main Perimeter firewall across the globe, routing all the internet traffic in and out of our infrastructure. It gives the secured way of filtering traffic as per our need. The best part of ASA is the support and trust of loyalty in last 10 years we just never have to reboot the device once also. Its credibility is amazing.
  • How we can manage: ASDM the GUI is so much easier to manage it even for a new guy also.
  • Traffic handling capacity
  • More secure and the different features it gives.
  • Support from the TAC team or from the community manages to handle issues very efficiently.
  • I would say Cisco should concentrate more how they will move way the traditional IPS to a new sand-boxing kind of environment.
CISCO ASA is suitable for every organization from MID range to HIGH RANGE. However, for small customers, they can buy Cisco product but support cost will be the challenge. However nowadays one tool is never enough, but Cisco gives us a unified way of managing infra with there different solutions. I agree they are more stable products comparing any products which are available in the Market.

This device is being used across the entire organization. It is currently our firewall and what guards us from exterior attacks. It is also functioning as our VPN provider for users that need access outside of the company.
  • Great user management
  • Good usage of ACE and ACL rules that control the network
  • Decent power for a VPN that can be easily created
  • Not user friendly
  • The GUI is nice, but it doesn't tell you what it does
  • Sometimes, it's hard to track down exactly what is going on
  • Definitely well suited for a small to medium business where it can highlight the usage of its firewall and small amounts of VPN connectivity.
  • It might get overshadowed in a larger company.

The Gold Standard in Enterprise Firewalls

Score 10 out of 10
Vetted Review
Verified User
Review Source
Cisco ASA is the industry standard for firewall software. I am not an expert on ASA by any means, but I have used several of the basic functions such as SSL VPN and configuring different VLANs for multiple devices. I only use the Command Line Interface, and never the ASDM which runs on a Java applet.
  • Customer support is Cisco's forte, and ASA is no exception. If you have issues, they are available 24/7 to help you resolve them.
  • Longevity. I still have a 5510 running that has been running for over 3 years without a reboot with zero issues.
  • URL filtering works great.
  • Get rid of the Java based ASDM
  • The licensing could be easier.
  • Packet filtering could use some improvement.
The ideal situations that Cisco ASA is best suited for are large enterprises with tons of traffic and several thousand users that need to have certain URLs or IPs restricted for security or client compliance reasons. ASA, of course, can be configured and used for any size environment, but the example that I can give that it would not be well suited for would be a very small business with only a handful of employees where IP or URL restriction is not necessarily required. The cost is also a factor, as ASA is very expensive.

We use the Cisco ASA as our public ingress and egress entry points across our organization. We have been using Cisco ASA for many years securing our users when accessing the internet and securing our network from users on the internet accessing websites we host. We also use Cisco ASA for VPN access. We have multiple site to site VPNs along with Cisco AnyConnect VPN for users accessing corporate resources when out of the office.
  • The Cisco AnyConnect VPN is used by our users and is a very easy and secure method for employees to access corporate resources.
  • The Cisco ASA 5585 can be configured in a cluster for larger throughput and high availability.
  • When purchased with FirePOWER the Cisco ASA can be configured to inspect the application layer of the packets for better threat detection.
  • The Cisco ASA can be configured via command line and with a GUI interface. The GUI interface needs work. It uses Java and depending on Java version you can have issues launching the application.
  • The Cisco ASA needs better logging for troubleshooting. When trying to narrow down an issue the logging needs more information.
  • Licensing can be difficult to understand and there are many options. Make sure you fully understand your needs before ordering.
For companies that want more granular security when it comes to internet access both external and internal the Cisco ASA can be configured in many ways. The AnyConnect VPN client is rock solid and very easy for users to initiate a VPN session.

For smaller companies the Cisco ASA may not be good fit as someone with network experience needs to administer the ASA. Other firewalls can be setup for use out of box.

We currently use Cisco ASAs both as our primary firewalls and for VPN. It has made our job in IT easier and with less stress knowing that we are more secure by using this product.
  • Filtering of traffic is made easier and we are able to better control our environment.
  • VPN is secure and easy to manage through our ASAs.
  • As part of our overall security strategy, Cisco ASAs help keep our perimeter more secure through their ability to customize to our company's needs.
  • More training on customization would be great.
  • Cisco could provide better Best practice reviews of our environment once set up.
  • More reporting features for Execs would help.
As an all in one security device, firewall, VPN, and IPS this system does it all. The ROI in itself is worth the initial cost for what Cisco brings to the table. Monitoring and reporting are easy to use and setup/configuring is a snap.

I use Cisco ASA routers in conjunction with Meraki Z1 & Z3 appliances to allow my remote teams to connect to the main office and for those traveling to easily be able to link back to the home network for easy access while on the road.
  • Site-2-site VPN tunnels.
  • Monitoring network traffic using firepower
  • VLANs
  • Better GUI interface
  • More robust trouble shooting tools
  • Clearer licensing agreements
I was able to connect my 5545x ASA to my Meraki Z1 & Z3 appliances for dynamic site-to-site von tunnels which allowed my remote field offices to use VoIP phones the same way employees in my main office use them. Simply dialling an extension allowed remote employees in other countries to receive calls as local calls.
