Frequently Asked Questions
Firewall rule optimization is the process of finding and removing unused, redundant, and shadowed rules from a rulebase to reduce risk and improve performance. FireMon automates firewall policy optimization by scanning rulebases, ranking rules by risk and usage, and routing removals through owner recertification before anything is deployed.
FireMon analyzes flow logs and policy logic to identify unused, redundant, and shadowed rules, then ranks them by risk and removal safety.
Safe removal workflows include owner recertification and rollback protection. Customers report large cleanups with zero outages.
Customer benchmarks report around 35% firewall performance improvement after systematic cleanup.
Change guardrails scan proposed changes before deployment to prevent reintroduction of risky or redundant rules.
