Over the years your firewalls have accumulated thousands of rules and objects, and many of these rules are now out-of-date or obsolete. Bloated rulesets not only add complexity to daily tasks such as change management, troubleshooting and auditing, they can also impact the performance of your firewall appliances, resulting in decreased hardware lifespan and increased TCO. Safely removing rules, however, is not easy as it may cause application outages. And periodic rule recertification projects are time-consuming and complex – with multiple teams trying to understand why rules were created in the first place.

Firewall Rule Recertification
In the past, the only way to recertify a rule was to manually review the comments field of each firewall rule. At a minimum, the comment should include the name of the original rule requester and the rule’s purpose. Due to the manual nature of the process, it is prone to errors and difficult to maintain.
