Fortinet FortiNAC CA-500F

Fortinet FortiNAC CA-500F

The FortiNAC CA-500F is a next-generation Network Access Control (NAC) appliance built to deliver full network visibility, Zero Trust access enforcement, and automated incident response across modern enterprise environments. It provides a comprehensive inventory of connected assets (including BYOD, IoT, OT, and IoMT), continuously assesses endpoint risk, and enforces least-privilege access using contextual identity and device behavior.

What It Does

FortiNAC helps organisations:

• Discover and maintain an up-to-date inventory of all network devices and users

• Classify devices using continuous profiling and behavioral analysis

• Enforce access policies based on role, device type, location, and risk posture

• Detect anomalies and non-compliant endpoints and trigger immediate remediation

• Share real-time contextual data with SIEM and security tools to improve response

Granular Visibility and Device Profiling

FortiNAC leverages AI and machine learning backed by FortiGuard Services to identify and profile devices across the network. It combines multiple information sources and profiling techniques to accurately classify endpoints, including headless IoT and OT assets. Profiling supports native categories and an expanded set via FortiGuard IoT Services, enabling richer identification and risk context for security operations.

Key visibility functions include:

• Active or passive scanning methods

• Agent-based, dissolvable agent, and agentless approaches

• Continuous monitoring and re-screening to reduce bypass attempts (including MAC spoofing)

• Passive traffic analysis using FortiGate appliances as sensors to detect anomalous patterns

Zero Trust Access and Intelligent Segmentation

FortiNAC extends Zero Trust to end devices with always-on identity checks and least-privilege access policies. After classification and identification, FortiNAC applies segmentation controls that restrict access to only the resources required.

Controls include:

• Role-based network access control and segmentation

• Dynamic VLAN steering and policy-based access enforcement

• Isolation or restricted VLAN placement for non-compliant devices

• Firewall segmentation integrations to contain compromised endpoints

This approach limits lateral movement and helps meet internal, industrial, and government compliance requirements.

Automated Threat Response

FortiNAC responds to network events in real time using automation policies that can trigger configuration changes on infrastructure devices and initiate remediation workflows. When suspicious behavior or anomalies are detected, FortiNAC can automatically quarantine endpoints and generate contextual alerts for security teams.

In environments using Fortinet Security Fabric, FortiNAC integrates with products such as FortiGate, FortiSIEM, FortiAnalyzer, FortiClient EMS, FortiSwitch, FortiAP, and FortiExtender to exchange security signals and trigger enforcement actions.

Third-Party Ecosystem Integration

FortiNAC supports extensive integration across networking, security, identity, endpoint security, and MDM ecosystems. It integrates with a wide range of vendors and validated device models to enable consistent discovery, profiling, and enforcement in heterogeneous environments.

Deployment Options

FortiNAC is an out-of-band solution, meaning it does not sit inline with user traffic. It can be deployed centrally and enforce control at the edge via integrations with network infrastructure and security tools.

Supported deployment models include:

• Hardware appliances

• Virtual machines across common hypervisors

• Cloud marketplace deployments

High availability options include active/passive failover and N+1 failover group designs for larger distributed environments.

Licensing

FortiNAC licensing is available in two main tiers:

PLUS License

Provides comprehensive endpoint visibility, advanced network access controls, onboarding for users/guests/devices, and reporting and analytics. Best suited for organisations that want granular control and visibility without requiring automated threat response.

PRO License

Adds real-time automated threat response, event correlation, guided triage workflows, and deeper incident response integrations. Best suited for organisations that want full visibility plus automated containment and response.

Licensing is available in perpetual and subscription formats based on concurrent endpoint counts.

Hardware Specifications (CA-500F)

The FortiNAC CA-500F is a 1U rack-mount appliance designed for small environments.

• CPU: Intel Xeon E-2278GE, 8-core, 3.3GHz base

• Memory: 16GB DDR4

• Storage: 2x 960GB SSDs

• Network Interfaces: 4x GbE RJ45

• RAID: Software RAID1

• Power: Hot-plug 1+1 redundant PSU, 174W input power

Capacity and Performance

The FortiNAC CA-500F is sized to manage up to 15,000 endpoints and supports strong performance across core NAC workloads including guest services, API operations, logging, and authentication (RADIUS). It can scale up through higher-tier appliances in the same series for medium and large deployments.

Ideal Use Cases

FortiNAC CA-500F is well suited for:

• Organisations expanding Zero Trust enforcement to endpoints

• Networks with large BYOD and IoT/OT footprints requiring continuous visibility

• Environments needing automated containment of non-compliant or compromised devices

• Hybrid IT operations requiring broad integration across network and security platforms
