FireMon Brings NVIDIA Cumulus Into Its Security Policy Manager as AI Data Centers Scale Up

FireMon is expanding its reach into the AI infrastructure stack by adding native support for NVIDIA Cumulus in its flagship Policy Manager platform. The move gives security teams unified visibility and governance across switching fabrics, firewalls, and cloud environments at a moment when AI-driven workloads are reshaping data center architectures.

NVIDIA Cumulus, the Linux-based network operating system acquired and integrated by NVIDIA in 2020, has become a critical foundation for high-performance computing and AI clusters. But as adoption has accelerated, enterprises have struggled to extend consistent policy controls into the networking layer, leaving blind spots that attackers can exploit. FireMon’s update closes that gap by normalizing Cumulus policy data alongside existing assets and automating change reviews in mixed-vendor environments.

“Adding NVIDIA Cumulus support is a major milestone for FireMon and for our customers modernizing around open networking,” said Jody Brazil, CEO of FireMon. “Policy sprawl didn’t stop at the firewall; it followed workloads into the fabric, the cloud, and now AI interaction layers. By adding NVIDIA Cumulus support, we’re giving customers one place to govern policy from ground to cloud to data center. The result is continuous visibility, faster time-to-remediate, and audit-ready compliance proof, outcomes CISOs now demand as AI adoption accelerates.”

Closing the Governance Gap

The integration brings three core capabilities. First, unified visibility, allowing Cumulus-managed networks to appear in the same workspace as firewalls and cloud controls, complete with normalized objects and topology. Second, change automation, so teams can simulate and verify Cumulus policy changes before deployment, cutting down on rework and compliance risk. And third, continuous compliance, with automated checks, evidence generation, and remediation tracking across the full policy estate.

FireMon says this approach responds to the operational burden exposed in its own data. According to recent FireMon Insights findings, 60 percent of enterprise firewalls fail high-severity control checks during initial evaluation, while 34 percent fail at critical levels. Those failures often reflect governance weaknesses rather than configuration errors, underscoring the need for consistent oversight across all control planes.

“Security teams don’t have the luxury of separate playbooks for each control plane. They need one governance model that spans firewalls, clouds, and fabrics, and they need evidence it’s working every day,” said Brazil.

Built for Modern Data Centers

Technically, the update leverages NVIDIA’s NVUE model and REST APIs to align with how operators already deploy and manage policy in Cumulus environments. FireMon also emphasized that its vendor-neutral philosophy remains intact. Teams can standardize on Cumulus without losing access to enterprise-grade security assurance or disrupting their operational models.

Policy Manager already integrates with major public clouds like AWS, Azure, and Google Cloud, as well as adjacent networking platforms such as Zscaler and Cisco ACI/NSX. Cumulus is now included in that roster, giving operations and audit teams a coherent picture of policy governance across increasingly heterogeneous environments.

The support is available immediately in FireMon’s 2025.2.6 release and can be enabled through a standard upgrade.

By extending its platform into NVIDIA Cumulus, FireMon is positioning itself as one of the few companies capable of managing policy end to end, from legacy firewalls to AI-intensive data center fabrics. The announcement reflects a broader industry reality: AI and HPC adoption is only as safe as the security policies that govern the networks they run on.
