Protect your network with Cisco ASA

Rating: 9 out of 10

February 19, 2026

Use Cases and Deployment Scope

Cisco ASA is an excelent solution for protecting your network and allowing traffic from internet to your internal services. The performance is very good, you can administrate the device via CLI and via GUI (ASDM), the deploy via ASDM can take a little longer than CLI but is simplier. We have used Cisco ASA for publishing service to internet and as a gateway to the internet for the internal traffic.

Pros

Robust device
CLI commands from Cisco
You can virtuallize the ASA
It can work in HA Failover

Cons

There's a bug where you can't have more than 200 host IP allowed in a VPN remote access
Sometimes ASDM take a long time to save the changes
It can improve the layer 7 filters for internet traffic

Likelihood to Recommend

It is a very good product for having as your perimeter for your network to internet, it works very good with NAT for publish services, but if you want to have a deep packet inspection on the traffic from your internal network to internet it is not the best solution, you can make IP filter, port filter, but you can't perform IPS functions or full packet inspection.

Use Cases and Deployment Scope

Cisco Adaptive Security Appliance (ASA) Software is used to create and enforce security policies to control the traffic entering and exiting the organization's network. We also use its VPN functionalities, allowing remote users or branch offices to securely connect to the organization's network.

Pros

Centralized Management
Intrusion Prevention System
VPN Concentrator

Cons

Cloud Integration
Reporting
User Interface and Management

Likelihood to Recommend

Cisco Adaptive Security Appliance (ASA) Software is well suited for large enterprise environments where robust firewalling capabilities are required to protect complex networks. Its VPN capabilities enable organizations to securely transmit sensitive data over public networks, ensuring confidentiality and integrity of communication between sites. Cisco Adaptive Security Appliance (ASA) Software may be less appropriate for small office/home office (SOHO) environments due to its relatively high cost, complexity, and resource requirements as well as unsuited for organizations with cloud architecture.

Cisco ASA Firewall Review

Rating: 9 out of 10

Incentivized

August 27, 2023

Use Cases and Deployment Scope

So we have shared usage of it and for us we really just implement rules and it to block allowed, deny whatever it is, traffic within our network.

Pros

We typically just use it to block traffic. It does what it is supposed to.
We just use it to monitor, block, allow. Blocks at the layer three.

Cons

Management, I would say a single pane of management that works would be good. Similar to the FTD, the FMC, being able to manage objects and security group objects in one pane. That would be good for the firewall versus having to manually create objects and monitor them across several different firewalls across several different contexts.

Likelihood to Recommend

Well, it's very suited for up to layer three maybe but it's not suited for layer seven or anything above layer three. So it's not that next-gen smart.

Adaptable yet Powerful Firewall Solution

Rating: 9 out of 10

Incentivized

June 20, 2023

Use Cases and Deployment Scope

We have several Cisco ASA and FTD firewalls in use within our organization. The ASA name is the legacy platform for the now current FTD firewalls. Both platforms provide security access for both internal networks to communicate and for external to internal network accesses. Cisco does a great job providing firewalls that are easy to manage and configure (by a skilled network administrator). The central management system; FirePower is pretty straight forward to deploy changes needed to any firewall across our network.

Pros

centralized management via a web based interface
easy , one time license setup
easy yearly software maintenance renewal process and easy access to tech support when renewed
adaptable and performance driven to protect networks
excellent analytics engine to detect malware and security events and block them

Cons

rather expensive to get into for many models
working with cisco acct management is not easy and getting into a streamlined renewal process can be problematic
some software upgrade require other security changes which mean its a continual upgrading process to stay current. and can be cumbersome

Likelihood to Recommend

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.

Choosing Cisco ASA and ASAv for reliable, scalable, and secure VPN

Rating: 10 out of 10

Incentivized

May 1, 2023

Use Cases and Deployment Scope

Our employee count was growing and we wanted to have a scalable, easy to administer and cost effective solution for a VPN concentrator. We wanted to support concurrent connections that was 2x our employee count. We chose Cisco's ASA as our VPN concentrator and that allowed us to scale with low administrative cost and a reasonable license/tooling cost. We also wanted to support 4 different entities, which ASA was able to help us achieve.

Pros

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.

Cons

For small companies that require DLP, ASA could add a basic DLP system
ASA has an easy web administration screen. It's look-and-feel could be improved
ASA could develop and/or promote agentless VPN access

Likelihood to Recommend

We moved our operations entirely to the cloud a few years ago. We loved the stability and scalability of the ASA and wanted to, somehow, keep using it. We discovered that ASA was available in the cloud as well and it was branded ASAv. We tested it and noticed that it was equally robust and a perfect fit for us. During the entire migration period, we used ASAv for cloud operations and put a lot of load on it. ASAv performed very well and gave us an easy transition from on-prem to the cloud.

June 22, 2022

Use Cases and Deployment Scope

We have used ASA to interconnect branch offices and also as a gateway. It's been a good product over the past years. Nowadays a lot of firewalls have overtaken the product. Especially in terms of user-friendliness. Also, the performance of the product should be improved compared to the other firewalls out there in the market.

Pros

Vpn
Natting
Av scan.
Web filtering.

Cons

Definitely when troubleshooting. It should be made simpler.
AV scan engines should be improved.
Configuration can be made simpler.eg: Fortigate.

Likelihood to Recommend

It's well suited for the rigid environment. In remote site locations where there is difficulty in accessing it's not a good idea as it's difficult for an end-user to provide remote access to the device. I understand it could be a security issue. But there are other means it can be secured. 2FA should be integrated.

December 9, 2021

Use Cases and Deployment Scope

Our business uses ASA'a as firewalls and for routing. We route 2 incoming connections and route them to allow our customers to come in on one dedicated SLA provisioned fiber line and a general internet line for internet browsing. We also utilize the failover capability of the ASAs for redundancy. We will utilize the security features when we have completed an upgrade project.

Pros

Routing
Firewall
Security

Cons

Ease of use
Cisco's purchase model is difficult
Level of skill required

Likelihood to Recommend

These appliances are great for small or medium business that needs a higher level of security will additional functions able to be purchased. It is a great reliable device for routing and firewall use, I've monitored user activity and utilization of our internet connection bandwidth noted outside attacks, DOS type when we see slowdowns, found infected computers by seeing them communicate with outside systems. A lot of helpful resources in the ASA

Use Cases and Deployment Scope

We have been using Cisco ASA as a part of our company for many years. It is used for routing, [dating], site-to-site VPN, remote access to our internal network for our employees when they are not in the office.

Pros

Allows the users to connect to our office network from outside the office.
Straightforward interface for configuration of firewall rules.

Cons

Support is a little expensive
The GUI could use an update
NextGen features

Likelihood to Recommend

If your organization is a small business and you don't require advanced-level security then you can go with the Cisco ASA firewall. However, when you want to use a full L7 with NG capabilities, you should go with firepower.
