Cisco ASA NGFW Review

Clustering architecture which offers zero downtime upgrades, keeping uptime close to 99.999%


What is our primary use case?

Service Provider Operations manipulating thousands of firewall rules deploying Network Access Translations (NAT) for various multiservice networks.

How has it helped my organization?

  • Easy and fast to deploy.
  • User-friendly GUI
  • REST API offering with rich capabilities which makes the product very robust.

What is most valuable?

Clustering architecture which offers zero downtime upgrades, keeping uptime close to 99.999%. This creates less stress on operations and network stability throughout the various maintenance tasks.

What needs improvement?

ASDM needs to be able to customize applets.

For how long have I used the solution?

One to three years.

What do I think about the stability of the solution?

REST API stability needs improvement in order for customizing resource allocation available to the user rather than just being there transparently. This way users can customize REST API and tailor it to their needs.
