Network Segmentation Solutions
Govern, validate, and continuously align segmentation policy across your hybrid environment
without replacing your existing infrastructure.
Segmentation without governance is just complexity
Large enterprises invest heavily in firewalls, VLANs, cloud security groups, and microsegmentation platforms to divide their networks into secure zones. But as environments scale, exceptions accumulate, workloads shift, and policies drift. Segmentation intent and real-world policy enforcement fall out of alignment.
The result: exposure gaps that attackers exploit, audit findings that erode confidence, and network security teams buried in manual rule reviews across disconnected tools with no unified source of truth.
FireMon acts as the control plane for network segmentation, enabling teams to define policy intent, validate enforcement across firewalls, cloud, and microsegmentation, and maintain continuous alignment as environments change.
60% of enterprise firewalls fail high-severity compliance checks on first evaluation.

Segmentation Governance That Reduces Risk and Proves Compliance
FireMon provides the governance and visibility layer that sits above your enforcement tools. It normalizes network segmentation policies across 120+ firewall and cloud platforms, including Palo Alto Networks, Fortinet, Check Point, Cisco, AWS, Azure, and GCP, into a single, searchable system of record.
Combined with deep integrations into microsegmentation solutions like Illumio, VMware NSX, and Zscaler, FireMon enables security teams to govern every layer of segmentation from one place: define what network access should look like, validate that enforcement matches intent, and detect drift before it becomes a breach.
Unlike tools that focus only on visibility, FireMon validates that segmentation policy is correctly enforced and aligned to intent across every control point. It is the governance layer above enforcement, not another enforcement point.
FireMon Network Segmentation Delivers:
Full Visibility Across Segments
Normalize and visualize segmentation policies across firewalls, cloud platforms, and microsegmentation tools in a unified view, eliminating blind spots across your hybrid environment.
Risk-Based Enforcement
Prioritize segmentation gaps by severity. AI-driven analytics from FireMon Insights surface the rules, objects, and access paths that pose the greatest risk.
Automated Zero Trust Controls
Validate segmentation against Zero Trust principles with a zero trust control plane built in partnership with Illumio for hybrid enterprises.
Continuous Compliance Alignment
Maintain audit readiness around the clock with 20+ preconfigured compliance assessments for PCI DSS, NERC CIP, NIST, ISO 27001, SOX, and more.
Real-Time Search with SIQL
Query segmentation policies across 25 million+ rules in seconds using FireMon's Security Intelligence Query Language for instant troubleshooting and validation.
120+ Platform Integrations
Govern segmentation across your entire estate with native support for 120+ firewall and cloud platforms, plus API-based integrations with SIEM, SOAR, and ITSM tools.
Define and Validate Segmentation Intent
A strong segmentation strategy starts with intent: which zones should communicate, through which services, and under what conditions. FireMon enables security teams to define that intent and continuously validate it against what is actually enforced.
- Map each network segment across on-premises firewalls, public cloud platforms, and host-level microsegmentation controls.
- Detect conflicts, redundancies, and overly permissive rules that undermine your segmentation posture.
- Correlate segmentation intent with firewall and cloud security policy to expose gaps and inconsistencies across enforcement layers.
- Leverage the Illumio integration to govern label-driven, host-level segmentation policies alongside network access control.
Automate Change Management and Compliance
Manual review of segmentation policies across thousands of rules and dozens of platforms is unsustainable. FireMon automates the change lifecycle from assessment through deployment, ensuring every modification is validated against compliance requirements before it reaches production.
- Evaluate proposed changes before implementation to prevent segmentation drift and unauthorized access.
- Generate audit-ready reports across 20+ regulatory frameworks, including PCI DSS, NERC CIP, NIST, and ISO 27001, without custom professional services.
- Integrate directly with ITSM platforms like ServiceNow and Jira to embed governance into existing change workflows.
- Reduce rule deployment time by up to 90% and audit preparation time by two-thirds through policy automation.
Benchmark and Optimize Your Segmentation Posture
Most organizations have no way to measure whether their segmentation is actually working. FireMon Insights changes that.
- Track nearly 50 KPIs across your segmentation environment to identify policy decay, unused rules, and configuration drift.
- Benchmark your segmentation posture against real-world industry data to understand where you stand relative to peers.
- Target the 30% of rules that are completely unused and the 95% of application objects that remain inactive, reducing complexity and attack surface.
- Deliver executive-level reporting that proves the ROI of your segmentation investments to the board.
Frequently Asked Questions
What Is Network Segmentation?
Network segmentation divides a network into isolated zones using firewalls, VLANs, and access control policies. Organizations use segmentation to limit lateral movement, reduce the attack surface, and contain breaches by restricting network traffic between defined segments.
How Does Network Segmentation Differ From Microsegmentation?
Network segmentation creates broad security zones using firewalls and VLANs to control north-south traffic. Microsegmentation applies granular, workload-level policies to restrict east-west lateral movement. Organizations need governance across both layers to maintain consistent Zero Trust enforcement typically at the workload or host level.
How Does FireMon Govern Network Segmentation?
FireMon normalizes segmentation policies across 120+ firewall and cloud platforms into a single system of record. The platform validates that enforcement matches defined intent, detects policy drift, and automates compliance reporting, without replacing existing infrastructure.
Why Does Network Segmentation Matter for Zero Trust?
Network segmentation enforces Zero Trust by eliminating implicit trust between zones and requiring verified access for every connection. FireMon’s zero trust network access governance continuously validates segmentation intent against real-world enforcement across hybrid environments.
Which Compliance Frameworks Require Network Segmentation?
PCI DSS, NERC CIP, NIST 800-207, ISO 27001, and SOX all mandate or recommend network segmentation to protect sensitive data. FireMon automates validation against these frameworks with over 20 preconfigured compliance assessments and audit-ready reporting.
Does FireMon Support Multi-Vendor Hybrid Environments?
FireMon normalizes policies across 120+ platforms, including Palo Alto, Fortinet, Check Point, Cisco, AWS, Azure, and GCP. Plus microsegmentation tools like Illumio, VMware NSX, and Zscaler. This vendor-neutral approach delivers unified segmentation governance across any cloud environment.
How Does Network Segmentation Improve Security and Performance?
Effective network segmentation strengthens incident response by containing breaches to isolated zones, improving network performance by reducing unnecessary traffic, and preventing lateral movement across network segments. FireMon governs this segmentation at scale to maintain consistent protection.
