FortiAuthenticator
Fortinet's Centralised Identity & Access Management Solution
What is FortiAuthenticator?
FortiAuthenticator is a scalable, enterprise-grade Identity and Access Management (IAM) platform that strengthens access security whilst simplifying authentication across complex IT environments.
It centralises identity services and enforces adaptive access policies, integrating seamlessly with Fortinet’s Security Fabric and existing enterprise identity infrastructures.
As a certified UK Fortinet partner, we setup and validate FortiAuthenticator subscriptions for enterprises seeking strong and adaptive access controls, unified identity services, and protection for sensitive data and resources at scale.
Key Benefits
- Unified Identity Security
FortiAuthenticator primarily ensures that only authorised users can access critical network resources. Centralising authentication and identity management, its robust support for multi-factor and password-less authentication reduces the risk of unauthorised access and supports critical compliance requirements.
- Streamlined User Experience
With support for Single Sign-On (SSO), identity federation and adaptive authentication, users benefit from seamless access across enterprise and cloud applications, improving productivity while maintaining strong security postures.
- Enterprise-Scale Flexibility
Available as hardware, virtual appliance, or cloud-hosted service, FortiAuthenticator scales from mid-size deployments to large, distributed enterprises and data centres, supporting thousands to hundreds of thousands of users with high availability options.
1. Multi-Factor and Adaptive Authentication
Supports a wide range of authentication mechanisms including FortiToken OTP, FIDO2 password-less, X.509 certificate-based access, SMS/email OTP and context-aware adaptive authentication. Enables granular policy enforcement based on device posture, network context and user risk profile.
2. Standards-Based Authentication Services
Provides centralised identity validation using RADIUS, TACACS+, LDAP, SAML 2.0, OAuth/OIDC and 802.1X. Ensures consistent, high-assurance authentication across firewalls, VPNs, wireless controllers, switches, cloud applications and third-party services.
3. Enterprise PKI and Certificate Authority
Operates as an internal Certificate Authority, issuing and managing X.509 certificates for users, devices and services. Automates certificate lifecycle management to support VPN authentication, Wi-Fi EAP-TLS deployment and Zero Trust network access architectures.
4. Identity Federation and Single Sign-On
Functions as a full SAML IdP or IdP proxy to deliver identity federation across on-premises and SaaS applications. Enables policy-driven Single Sign-On aligned to enterprise authentication standards and compliance requirements.
5. Endpoint-Integrated Identity Enforcement
Leverages trusted endpoint telemetry via FortiClient and Security Fabric integration to validate device posture before session establishment. Supports transparent user identification through Fortinet Single Sign-On (FSSO) for precise access control.
6. Operational Identity Services
Includes self-service portals for user registration, token management and password recovery, reducing administrative overhead. Offers comprehensive logging, auditing and API-based integration for SIEM, SOC and identity governance workflows.
