Cisco ASA Firewall Review

Reliable product which I'd like to see include a web filtering functionality.

Valuable Features

It blocks all outside to inside traffic and only permits the specific internet traffic from the outside. VPN functionality is very useful, we can create remote access and tunnel VPN in the simplest way.

Improvements to My Organization

It blocked all kinds of internet attacks from outside like DOS or DDOS and avoided any down time. We created a remote tunnel from head office to data center network for easy access of servers that make working fast and they are easily manageable.

Room for Improvement

It would be great if they would add web filtering functionality to this product.

Initial Setup

It is a little difficult in newer IOS versions where the use of the NAT command is different. Otherwise its straightforward to configure.

Implementation Team

I deployed it in-house with my team.


This solution reduces any downtime therefore business continuity is not disturbed - that is ultimately ROI.

Pricing, Setup Cost and Licensing

It is one time cost of about $10,000 and there is no day to day cost.

Other Solutions Considered

Yes, I evaluated Fortigate, SonicWall and Juniper but found Cisco ASA to be the best solution for us above all of the others.

Other Advice

Cisco ASA is a reliable product and it benefits you a lot in your network.
