FireMon: 58% of Firewalls Fail High Severity Checks


FireMon: 58% of Firewalls Fail High Severity Checks

FireMon, the leader in network security policy management and the control plane for security policy, today unveiled FireMon Insights 2.0, a major advancement in AI-driven policy intelligence for hybrid enterprise networks. The launch comes as new analysis from FireMon highlights the growing reality that policy environments are becoming too complex to govern manually at scale, resulting in accumulating outdated rules, unmanaged changes, and unresolved risk at a pace much faster than teams can remediate.

Quick Intel

  • 58% of firewalls fail high-severity checks; 48% fail at critical severity.

  • 69% of firewall rules are unused and 45% lack an owner or documentation.

  • 17% of rules are redundant or shadowed, increasing operational complexity.

  • Automated policy workflows show 67% lower change-related risk delta compared with manual changes.

  • Analysis comprises 9.2 million policy checks across complex hybrid networks.

  • FireMon Policy Manager customers reduced control failures up to 31% in first 6 months.

The Structural Security Operations Problem

"Firewall complexity is no longer just an operational problem. It is a control problem," said Jody Brazil, CEO of FireMon. "Security teams have massive investments in firewalls, cloud, and segmentation platforms, but without control of policy those environments become difficult to manage securely. The problem is no longer lack of tools. It is lack of operational control."

The new operational analysis from the FireMon Insights platform comprises 9.2 million policy checks and examines policy behavior across complex hybrid networks at scale. It reveals a structural security operations problem: manual policy management is woefully inefficient, and allows risk across the attack surface to continue to expand rapidly. This is primarily due to creating an environment in which high severity policy failures persist over extended periods of time, exacerbated by unused and redundant rules.

The FireMon Insights 2.0 release addresses this discrepancy by moving beyond static dashboards and point-in-time reporting to deliver continuous operational intelligence for enterprise policy environments, powered by AI. More than simply layering AI onto reporting, the new version imbues AI with the operational context behind policy data. Instead of simply reporting policy status, the AI-powered platform helps security teams identify where operational risk is accumulating, which issues persist over time, and where automation can reduce policy complexity and improve control across hybrid networks.

Key Findings

Security controls are only as effective as the policy that governs them, and the lack of a policy control plane allows these issues to persist and compound. The anonymized data from FireMon Insights deployments reveals:

58% of firewalls fail high-severity checks; 48% fail at critical severity. 69% of firewall rules are unused and 45% lack an owner or documentation, introducing audit gaps and operational blind spots.

17% of rules are redundant or shadowed, increasing operational complexity and masking potential misconfigurations.

Automated policy workflows show a 67% lower change-related risk delta compared with manual changes.

New Capabilities in Insights 2.0

Policy Change Intelligence: Built-in policy change analysis that eliminates manual export and spreadsheet work while identifying rework, operational churn, and opportunities to reduce policy risk through automation.

Workflow Intelligence: Visibility into how change requests move through the policy workflow, highlighting rejected requests, redesign loops, approval bottlenecks, and opportunities to safely increase automation.

Automation Effectiveness: Analytics that identify repetitive manual work and pinpoint where automation can reduce cost, improve consistency, and lower policy change risk.

Control Failure Analysis: Deeper visibility into which controls fail most often and where failures recur, helping teams prioritize the highest-risk issues across the environment.

Policy Posture Trends: Understand where policy is breaking down, what is driving exposure and what to fix first through scoring and trend analysis over time.

Control-Level Visibility: Domain-based, control-level pass/fail visibility that helps teams quickly identify where policy and compliance issues exist across managed devices.

CEO Perspective on AI-Driven Attacks

"Technologies like Mythos are shining a bright light on a reality security teams can no longer ignore: any connected system is vulnerable," said Brazil. "As AI accelerates the speed and scale of attacks, firewalls, segmentation, and policy governance become more important than ever. Our Insights data shows most organizations still lack the operational control needed to consistently manage policy across hybrid environments. That is why network segmentation, microsegmentation, and continuous policy governance are becoming foundational to reducing attack surface and limiting blast radius."

About FireMon

FireMon is the founder of Network Security Policy Management (NSPM) and the control plane for security policy across modern enterprise networks. FireMon provides an authoritative layer above enforcement technologies, continuously validating that deployed rules, segmentation, and access controls operate as designed across firewalls, cloud networks, and microsegmentation platforms.
