What it sells: FireMon

What Security Manager does[5][7]
FireMon Security Manager is the foundational platform required by the Policy Planner add-on module. Risk Analyzer requires Security Manager for policy visibility, network topology, and analytics.
What Policy Planner does[5]
Policy Planner manages the full change lifecycle, analyzing proposed rules in real time, checking them against compliance requirements, and deploying them across on-premises and cloud environments. Policy Planner performs pre-deployment compliance checks against requirements such as PCI DSS, NERC-CIP, NIST, and DORA. Policy Planner integrates with ServiceNow and Remedy for ticket tracking and automated reviews. Policy Planner handles modifications to network objects, service objects, and group objects across hybrid and multi-cloud environments.
What Policy Optimizer does[2][5]
Policy Optimizer handles identifying redundant, shadowed, or unused rules. Policy Optimizer adds event-driven rule review and recertification to keep policy clean over time. Paired with Policy Planner, Policy Optimizer makes rule decommissioning fully automated.
What Risk Analyzer does[7]
Risk Analyzer provides real-time risk assessment by correlating vulnerabilities with network policy, simulating attack paths, and prioritizing remediation based on threat impact. Risk Analyzer integrates with scanners like Qualys, Rapid7, and Tenable. Risk Analyzer detects misconfigurations, exposed paths to vulnerable assets, overly permissive rules, and potential policy violations that increase attack surface. Risk Analyzer supports what-if analysis for attacks and changes.
What Workbench Agentic AI does[5]
Workbench Agentic AI provides a guided, AI-assisted experience for rule recommendations. The agentic AI assistant analyzes the environment to identify impacted devices and policies, then generates rule and object change recommendations. Engineers review and save the proposed changes, and the plan then proceeds through the applicable assessment and approval workflow before implementation. Workbench Agentic AI requires a FireMon Insights activation.

What it sells: Zero Networks

What Identity Segmentation does[1][2][8]
Zero restricts privileged account access to operational needs only to remove the risk of credential theft. Zero learns all logon activities, account behaviors, and asset access patterns to create automated policies based on legitimate behavior. Service, admin, and agent accounts are restricted to pre-approved assets and logon types, so lateral movement and unauthorized access are blocked even if credentials get stolen. Admins can only log on to pre-approved assets after MFA.
What Secure Remote Access does[1][2][5][7][12]
Zero combines the speed of VPN with the security of ZTNA to connect remote employees and vendors. Policies allow user access to all or pre-approved apps and services. Zero remote access enforces access controls, tracks user activity, creates audit trails, and enforces MFA user authentication.
What RPC Firewall does[2][10]
RPC Firewall allows only legitimate and crucial RPC traffic and blocks unwarranted operations. RPC Firewall addresses threats including lateral movement, remote code execution, internal discovery, and relay attacks. Domain Controllers, Certificate Authorities, and Federation Services are essential services covered by the solution.

About FireMon

FireMon is a network security company focused on firewall policy control for the hybrid enterprise. FireMon helps organizations manage and analyze security policy across multi-vendor firewalls, cloud networks, and microsegmentation environments with real-time change visibility, risk analysis, automation, and continuous compliance. FireMon gives organizations one governed point of control across on-prem, cloud, and hybrid environments, including the segmentation layer. FireMon builds agentic AI into the automation and risk analysis behind its policy control. FireMon connects policy management across more than 120 supported firewall, cloud, network, microsegmentation, and workflow technologies.[1][2][3][4]

FireMon states that firewall policy rarely lives in one place and that network change rarely happens in isolation. Zero Trust, microsegmentation, cloud migration, and AI all increase the number of policies deciding who and what can reach what, according to FireMon. FireMon says security teams must reduce exposure, support critical applications, respond to change, and produce defensible evidence for auditors. FireMon aims to analyze, detect, and mitigate policy-related vulnerabilities that could expose an organization to outages or attacks. FireMon detects and analyzes firewall policy changes in real time so that risky changes, compliance failures, and unexpected access do not sit unnoticed.[2][4]

Policy Planner is FireMon's firewall change automation software. Policy Planner manages the full change lifecycle, analyzing proposed rules in real time, checking them against compliance requirements, and deploying them across on-premises and cloud environments. Policy Planner is an add-on module that requires FireMon Security Manager as the foundational platform. Policy Planner performs pre-deployment compliance checks against internal and regulatory requirements such as PCI DSS, NERC-CIP, NIST, and DORA. Policy Planner integrates with ServiceNow and Remedy, enabling ticket tracking, comment logging, attachment uploads, and automated reviews across change management workflows. Policy Planner supports firewall rule changes and handles modifications to network objects, service objects, and group objects across hybrid and multi-cloud environments. Policy Optimizer handles identifying redundant, shadowed, or unused rules, and pairing Policy Optimizer with Policy Planner makes rule decommissioning fully automated.[4][5]

Policy Planner Workbench is the interface for building and editing change plans within Policy Planner. The Change Plan Editor shows all rules and objects in a policy in a unified, table-based view. Workbench supports the Access Request workflow only at the general availability release. Saving a plan in Workbench records proposed changes and does not deploy them to a firewall. Workbench Agentic AI provides a guided, AI-assisted experience for rule recommendations. Workbench agentic AI analyzes the environment to identify impacted devices and policies, then generates rule and object change recommendations. Engineers review and save the proposed changes, and the plan then proceeds through the applicable assessment and approval workflow before implementation. Workbench agentic AI requires a FireMon Insights activation.[5][6]

Risk Analyzer is an add-on module for Security Manager that provides real-time risk assessment by correlating vulnerabilities with network policy, simulating attack paths, and prioritizing remediation based on threat impact. Risk Analyzer requires FireMon Security Manager as the foundational platform for policy visibility, network topology, and analytics that power risk modeling and attack path simulation. Risk Analyzer integrates with scanners like Qualys, Rapid7, and Tenable to correlate vulnerability data with network policy. Risk Analyzer prioritizes vulnerabilities by ease of exploitation, penetration depth, and business impact of a successful breach. Risk Analyzer detects misconfigurations, exposed paths to vulnerable assets, overly permissive rules, and potential policy violations that increase attack surface. Risk Analyzer supports what-if analysis for attacks and changes. Policy Optimizer adds event-driven rule review and recertification to keep policy clean over time.[2][7]

FireMon Asset Manager integrates with EDR tools to compare its real-time index of discovered network devices against what those EDR platforms are actually managing. FireMon Asset Manager surfaces endpoints that lack an agent or fall outside current coverage. FireMon's Cloud Defense capabilities help identify misconfigurations and vulnerabilities across cloud environments. FireMon normalizes policy from supported firewall, cloud, and microsegmentation platforms, including AWS, Azure, and Google Cloud, alongside on-premises firewalls, into one governed model. FireMon supports continuous assessment of firewall and cloud policy against internal standards, documents rule changes and approvals, and flags policy violations before they are deployed. FireMon does not inspect traffic or detect intrusions itself, and governs the rules that shape what traffic is possible.[8][9][10][11][12]

Global enterprises, government agencies, and service providers use FireMon to keep security policy aligned across their environments. FireMon serves 1,800+ organizations across 70+ countries with 24/7/365 support and geo-aligned teams. FireMon is channel-only by design, and every deal transacts through the channel. Resellers, MSSPs, GSIs, distributors, and technology partners can bring FireMon into the architectures and services they already deliver. Insight Partners made a major investment in FireMon. FireMon launched a Zero Trust control plane for hybrid environments, validating segmentation and access enforcement. FireMon expanded operations to serve enterprises across 70+ countries, establishing 24/7/365 global support infrastructure and a TAM program.[2][3][6]
