Report highlights widespread misconfigurations, outdated rules, and policy bloat.
Around two-thirds of enterprise firewalls fail high-severity compliance checks immediately upon evaluation, with a further 34% falling short at critical levels.
A new report from FireMon highlights widespread misconfigurations, outdated rules, and policy bloat across on-prem, cloud, and hybrid environments.
Among the most alarming findings: 95% of application objects and 82% of service objects were unused, adding unnecessary complexity; 30% of firewall rules were completely inactive; and more than 60% lacked ownership or documentation - leaving organisations exposed to operational and compliance risks.
In over ten percent of cases, rules were redundant or shadowed, degrading performance and obscuring dangerous misconfigurations.
“Firewall complexity isn’t just a configuration issue, it’s a threat to resilience and trust,” said FireMon CEO Jody Brazil. “Security teams are buried under policies they can’t manage or justify. FireMon Insights cuts through that noise.”
