Cisco ASA Firewall Review

It currently does not support VPN, but I like the documentation, reliability, and support.

What is most valuable?

  • Site-to-site IPsec VPN
  • Remote IPsec VPN
  • Reverse route injection

How has it helped my organization?

Cisco Context gave us the feature of creating a virtual firewall, which is good. It provides us with maximum network isolation. Also impressive is the ISP redundancy.

What needs improvement?

WCCP, and URLs, in the Cisco ASA Context both need work. When changing from single mode to multiple mode or back, the commands must be done from the command line (CLI) and cannot be done via the ASDM GUI interface. ASA context should be able to support site-to-site VPN, but the current Cisco Context does not support VPN

For how long have I used the solution?

I've used them for six years.

What was my experience with deployment of the solution?

During the deployment of WCCP, we noted some loopholes like it only supports ports 80 & 443. Application which is running on multiple ports doesn't work with WCCP and to make it work we need to allow respective traffic outside the firewall.

What do I think about the stability of the solution?

Sometimes there is an issue with the site-to-site VPN.

What do I think about the scalability of the solution?

In certain cases, like an any access-list, if we add a URL the Cisco ASA access-list does not resolve that URL while this can be done in Juniper, and Fortinet.

How are customer service and technical support?

Customer Service:


Technical Support:


Which solution did I use previously and why did I switch?

I have migrated some set-ups from Cisco to Juniper, but not from Juniper to Cisco.

How was the initial setup?

We have multiple ASA firewalls for different clients now we migrated to Cisco Context.

What about the implementation team?

It was done in-house.

What was our ROI?

It's 8/10.

What other advice do I have?

If it is for a banking domain, your organisation should use Cisco which can assure better security than any other vendors' products. Also, they have the best documentation, reliability and support.

Which version of this solution are you currently using?

5550, 5525, 5520,5510,5505. IOS version 8.1, 8.3, 9.0
