FortiNAC Core Capabilities

From device discovery to automated threat response — FortiNAC enforces zero-trust access at the network edge.

Device Discovery & Profiling

FortiNAC discovers all devices on the network — managed, unmanaged, IoT, OT, and BYOD — using passive and active techniques. 5000+ built-in device profiles automatically classify device types (laptops, phones, printers, cameras, PLCs) without agent installation.

802.1X Authentication

Enforce 802.1X port-based authentication on wired and wireless networks. RADIUS integration with Active Directory, Azure AD, and LDAP for employee authentication. Dynamic VLAN assignment based on user role, device type, and health posture.

BYOD Onboarding

Self-service BYOD portal for employees to register personal devices. Certificate-based onboarding (EAP-TLS) for secure authentication without sharing domain passwords. Device registration, policy acceptance, and automated VLAN assignment — without IT involvement.

Guest Network Management

Customizable guest captive portal with sponsor-based access, time-limited credentials, and usage logging. Guests isolated in a separate VLAN with internet-only access. Audit trail for CERT-In compliance.

IoT & OT Device Segmentation

Automatically identify and segment IoT devices (IP cameras, HVAC, building management) and OT assets (PLCs, SCADA, industrial sensors) into dedicated VLANs. Enforce strict micro-segmentation policies — IoT devices cannot communicate with corporate servers.

Automated Threat Response

When FortiNAC detects a non-compliant or infected device, it automatically quarantines it — moving it to an isolated VLAN and blocking all network access except remediation servers. Integration with FortiGate, FortiEDR, and FortiSOAR for orchestrated response.

Why Choose Ogma for FortiNAC

Fortinet-certified expertise, multi-vendor network experience, and compliance-aligned policy design.

Fortinet NSE Certified

Ogma's engineers hold Fortinet NSE 7 certification with deep expertise in FortiNAC deployment, FortiGate integration, and 802.1X architecture. We have deployed FortiNAC in enterprise, healthcare, and education environments across India.

Multi-Vendor Network Support

FortiNAC integrates with network switches from Cisco, HPE Aruba, Fortinet, Juniper, and other vendors via RADIUS, SNMP, and CLI. You don't need to replace your existing switching infrastructure to deploy FortiNAC.

Policy & Compliance Expertise

Translating complex security requirements (DPDPA, ISO 27001 A.9, RBI IT Framework) into practical NAC policies is Ogma's specialty. We design policies that enforce compliance without blocking legitimate business access.

Our FortiNAC Deployment Process

A structured, phased approach that minimises disruption and delivers full NAC coverage.

1
Network Discovery Audit

Deploy FortiNAC in visibility-only mode. Discover all connected devices, profile device types, and map VLAN topology. Identify unmanaged devices and access policy gaps.

2
Policy Design

Design 802.1X, BYOD, guest, IoT, and OT policies. Define VLANs, RADIUS server integration, and quarantine workflows. Review with stakeholder IT and security teams.

3
Pilot Deployment

Deploy 802.1X enforcement on a pilot floor or building segment. Test employee, BYOD, guest, and IoT device flows. Validate automated quarantine response.

4
Full Rollout

Phased rollout switch-by-switch, building-by-building. Enforce 802.1X on all access ports. Monitor for false positives and tune device profiles.

5
Ongoing Management

Monthly device profile updates, policy tuning, and new device type onboarding. Integration with FortiGate firewall policies and FortiAnalyzer logging for SOC visibility.

FortiNAC vs Legacy Network Security

See the difference between a network with full NAC enforcement and one relying on legacy perimeter controls alone.

With FortiNAC

  • Every device identified, profiled, and tracked in real time
  • 802.1X enforces authenticated access — no unauthorised devices
  • IoT devices automatically segmented to isolated VLANs
  • BYOD onboarded securely with certificate authentication
  • Non-compliant devices automatically quarantined in <2 minutes
  • Guest access controlled with sponsor approval and time limits

Without FortiNAC

  • Unknown devices connect to network without detection
  • No visibility into whether connecting laptops have antivirus or patches
  • IoT cameras and building management systems on same VLAN as servers
  • BYOD uses shared Wi-Fi password — shared credentials across personal devices
  • Infected device spreads malware freely until noticed by helpdesk
  • Guests use same SSID as employees — no isolation or logging

Frequently Asked Questions

Common questions about FortiNAC, 802.1X, and NAC deployment in Indian enterprise environments.

NAC is a security technology that controls which devices can connect to your network and what they can access. Without NAC, any device — personal laptop, IoT gadget, contractor device — can connect to your network and communicate freely with your servers. FortiNAC enforces authentication, profiles every device, and assigns it to the appropriate network segment based on identity and posture.

No. FortiNAC supports multiple enforcement modes — 802.1X for managed switches that support it, VLAN-based enforcement for legacy switches via MAC address table polling, and agent-based enforcement for Windows endpoints. You can enforce NAC even in environments where 802.1X is not supported on all switches.

IoT devices (cameras, sensors, PLCs) typically don't support 802.1X. FortiNAC handles them through device profiling — identifying the device type by MAC OUI, DHCP fingerprint, and network behaviour — and automatically placing them in the correct IoT VLAN via MAC-based VLAN assignment. No agent or 802.1X client is required.

Yes. FortiNAC integrates with Cisco Catalyst and Meraki switches (and switches from HPE Aruba, Juniper, and others) via RADIUS, SNMP, and CLI. Active Directory integration for user authentication is standard — FortiNAC queries AD groups to determine user roles and assign the correct VLAN and firewall policy.

A typical enterprise deployment (visibility + 802.1X + guest portal) takes 4-8 weeks: 1-2 weeks for network discovery audit and policy design, 1-2 weeks for pilot deployment and testing, and 2-4 weeks for full rollout across all switches. IoT and BYOD policy tuning continues for 4-6 weeks post-rollout as device profiles are refined.

A quarantined device is moved to an isolated VLAN with no access to corporate resources — only a remediation server (typically with antivirus update servers, Windows Update, and a helpdesk ticket URL). The device owner receives a notification explaining the quarantine reason and remediation steps. Once the device passes posture checks (AV updated, patch applied, etc.), it is automatically returned to its normal VLAN.

Yes. FortiNAC is part of the Fortinet Security Fabric — it integrates with FortiGate via REST API and Fabric Connector. When FortiNAC detects a non-compliant device, it can automatically trigger a FortiGate policy change to block the device's traffic at the firewall layer as well. FortiAnalyzer receives FortiNAC events for centralized logging and correlation with firewall events.
