Cisco Secure Firewall Threat Defense Virtual (formerly NGFWv) Pros and Cons

It provides great control over incoming and outgoing traffic with most secure rules implemented for best network security. When acting as VPN- Cisco anyconnect VPN also provides most secure connection and I am able to do my work from anywhere with the key on my side. Review collected by and hosted on G2.com.

Its packet filter sometimes drop packets which are of use and skip sending any error. So it becomes hard to track when you loose one. Review collected by and hosted on G2.com.

CLI can be problematic for those without knowledge. But that can also be a positive Review collected by and hosted on G2.com.

Clean command line, and the ability to quickly navigate the device over CLI. Uniform IOS CLI makes it easy to manage with simple cisco route/switch background. Ability to run for long periods of time without intervention. It doesn't do random things, or act funny and need a reboot. It just runs and runs. It's also a bit like a swiss-army-knife for the network. You can divide traffic up how you want to. Multiple NAT pools, source based routing, etc. QoS and packet prioritization. It can even provide DHCP and other basic network services. Review collected by and hosted on G2.com.

On Cisco IOS firewall, I have been unable to get a given NAT group to utilize a NAT pool of address with PAT overload. Since I was overloading the NAT group, I eventually needed to switch over to PAT only, which was an acceptable solution, but not what I had wanted to do. Debugging can also be difficult.

Cisco firewall's are one of the leaders in security appliances and the Adaptive Security Appliance line is no exception. Configuration through the ASDM web interface is simple and quick. Configuration through the command line requires more knowledge but is far more customizable to business needs. Cisco ASA Firewalls support interopability with many vendors and documentation is widely available. Review collected by and hosted on G2.com.

Understanding the full suite of features is a difficult task, as well as learning the licensing structure. Cisco nickels and dimes for many features such as 'inside hosts' that refers to how many devices can be connected at once. It seems like you hear about security vulnerabilities every week on Cisco Firewalls, however Cisco is quick to respond and release updates to fix these issues.
