FireMon Delivers Policy Visibility and Control to Keep Pace with Rapid AI Infrastructure Growth

The Challenge

A leading AI infrastructure company faced mounting security challenges as they prepared for explosive growth that would more than double their firewall infrastructure. With overly permissive rules created during rapid data center migrations, zero rule documentation, and constant friction between cloud and on-premises environments, their small security team needed a solution that could scale with ambitious expansion plans.

The company sought to:

• Identify and clean up overly permissive firewall rules created during rapid data center expansion.
• Document rule purpose, business ownership, and expiration dates to strengthen accountability.
• Improve policy visibility across AWS and on-premises environments to reduce operational delays.
• Automate compliance checks and rule reviews so a small security team could support continued growth.

The Solution

FireMon delivered an automated, scalable policy management platform that By implementing FireMon Security Manager with Policy Optimizer, the organization gained immediate visibility into critical security policy violations, discovered rules "allowing internet access in places that it shouldn't have been," and established a foundation for automated governance that supported growth from 36 to 46+ firewalls over 18 months.

FireMon Delivered

• Security Manager for policy visibility and compliance monitoring across their Palo Alto Networks environment
• Policy Optimizer for automated rule recertification and cleanup
• 80 firewall licenses with quarterly true-up agreement to accommodate rapid expansion
• 5,000 network device licenses for end-to-end topology mapping
• Fully distributed architecture with multiple data collectors for global coverage

Results

• Uncovered unexpected internet access and policy violations during the production proof of concept.
• Gained visibility into firewall rules that fell outside data center security requirements.
• Established a foundation for automated rule recertification, policy cleanup, and compliance monitoring.
