Years of exceptions leave firewalls bloated and risky. A safe clean-up method.

Why rule bases bloat
Temporary rules become permanent, owners leave and nobody dares remove anything.
Clean-up steps
- Export and analyse hit counts
- Identify unused and shadowed rules
- Contact owners for validation
- Disable before deleting
- Document the business reason for each remaining rule
Prevent recurrence
Require expiry dates for temporary rules and review quarterly.
Results
Cleaner rule bases improve performance, simplify audits and reduce attack surface.
