Firewall rule bases grow over time as rules are added for new requirements and old rules are never removed. The average enterprise firewall has hundreds of rules - many of which serve no current business purpose, create unexpected permission paths, or conflict with each other. BetterWorld Technology performs a structured rule base review and implements a governance process that keeps the rule set clean.
Our firewall had 340 rules. BetterWorld Technology's audit found 120 that referenced systems that no longer existed and 18 that created overlapping permissions we did not intend.
