Case Study: a multinational missile systems and defense electronics manufacturer restores real-time firewall policy visibility with FireMon

a multinational missile systems and defense electronics manufacturer restores 100% real-time policy visibility with FireMon

A multinational missile systems and defense electronics manufacturer faced a significant security compliance challenge after its firewall policy management platform was discontinued, leaving roughly 50 firewalls from multiple vendors on an unsupported tool. With no real-time visibility into policy changes and no structured process for rule recertification, the company's alignment with NIST and ISO 27001 requirements was at risk. They sought a fully supported, real-time alternative from FireMon to restore visibility and establish a compliant recertification process.

FireMon deployed its Security Manager solution to replace the unsupported platform, restoring real-time policy visibility across the entire multi-vendor firewall estate. The implementation of Policy Optimizer closed the recertification gap, establishing a structured, audit-ready workflow mapped to NIST and ISO 27001. As a result, FireMon delivered 100% real-time policy visibility, unified three firewall vendors in a single compliance view, and created a foundation for extending policy management into future cloud environments.
