Cisco Adaptive Security Appliance (ASA) Software vs. pfSense

Cisco ASA's are great for internal network connected access between a firewall and the central management server. And, for complex networks where high security requirements with overly strict compliance are necessary. For networks with limited connectivity to the core or for poor network connectivity these are not the best solution. There are other more stand-alone firewall's that do this better. These firewall's are a little more complex to set up to start with so significant knowledge of these devices is required to set them up and ensure they are best practice installed.

Because pfSense is built around open source software, it is very convenient to be able to deploy in the event of hardware failure. We once had a client with a proprietary router that failed. While the router was under warranty, the expected time for the new router to arrive was about 2 weeks. We decided to implement pfSense for the client as a stop gap and ultimately ended up deploying the full enterprise appliance. Being able to get up and running using commodity hardware was a huge win for the client. We've also had a great amount of success deploying pfSense hardware at apartment complexes. The DNS resolver works great and we've had no issues handling multiple VLANs with various DHCP scopes on it. Finally, we've had clients that require having a failover cluster. Utilizing the built in CARP capabilities, we've been able to provide a very robust failover system that requires little maintenance and no downtime in the event of equipment failure.

• ASA is our VPN concentrator. The client and server are very stable and very easy to use
• ASA also offers Intrusion Prevention, to an extent. This is also very useful for an improved security posture for a small company
• ASA allowed us to scale very quickly. We could onboard clients, partners, and consultants and give them a great onboarding experience as well
• Administrative costs with ASA are low. It's very easy to administer.

• Easy to use. Good user interface design! Easy to understand and easy to set up.
• Lower hardware requirement. 3 years ago, we used an old PC to run it. Now, we have changed to a router device with Celeron CPU and 8GB RAM. It runs smoothly with a 1000G commercial broadband.

• The ASDM software is at times a nightmare to install because of different java versions[.]
• [The firewall] could do with a power button, just to be able to do a hard reboot when needed[.]
• It would be nice to manage the firewall via the web on port 443[.]

• I did kind of mention a Con in the Pro section with OpenVPN.
• When I create a config for an employee other employees are able to login to that config.
• I could be doing something wrong when I am making it - I am not afraid to admit that as I am pretty new to all of this, but it seems like it builds a key and I would think the key would be unique in some way to each employee, but I could be wrong.
• I actually do not have a lot of Con's for this software - I did not get to set this up on our work network so I am not sure of any downfalls when installing.
• I installed this on my personal machine in a Hyper-V environment to get a feel for it before I started working on it at work and it seemed pretty smooth. I didn't run into any issues.

To be honest there has been now great products out in the market compared to Cisco ASA. I beleieve Cisco has to do a lot of improvement in this area. The other defeiniete factors is the cost when it comes to renewals which is always a premium on Cisco products

The interface is simple, has sane defaults, and is consistent throughout.

I generally have not noticed the outages, however since it's a machine it can malfunction, we need to implement the firewall infrastructure in such a way that it is highly available with device failure, region failure etc. Else any solution will be having the issues if they are not build with resiliency.

The support is usually very good and gets back to you very quickly. However I had some instances of when two engineers will give me wildly different answers to what I thought was a simple question. Overall however I do rate the support highly and they are generally always very good.

It was quite a good one, how ever requires an expertise to deploy hence the SMB segment would be finding it difficult to implement this product. The one good reason is that there are lot of ASA certified engineers in compared to the other certified engineers. Hence this resembles positively on the deployment as you have quite a lot of experienced engineer on your deployment

We were using [pfSense] before in our environment but we regularly facing difficulties over it due to software bugs & downtime. After implementing Cisco ASA, it resolved our availability issue & provides us a reliable solution with the best security features & easy to understand GUI.

While you can get the performance out of other products, pfSense offers the unique ability to put other services on the same device. Products such as Untagle's NG Firewall and SonicWall's TZ series offer cost effective options for firewall and VPN services, having incoming load balancing and connection proxies on the same device as the firewall offers extremely easy configuration and day to day management of network services

• Most network engineers have worked with ASA, so there is no need for re-training when adding or turning over staff
• Current configs from older devices plug in easily, and are operational on larger devices if an upgrade is required
• Many support options available

• Using pfSense has allowed us to build a professional network in our small office without needing a lot of proprietary hardware, saving thousands of dollars in IT infrastructure investment.
• The cost for using pfSense is free, so it's a great option for those who don't have a large IT budget
• pfSense utilizes all of the industry standard services to provide all of it's functionality, so support for service-level issues is readily available
• Because of how much work has been put into pfSense to make it rock solid and reliable, we're able to support our network with minimal IT staffing, saving us thousands of dollars/year in personnel alone.
