Unified AI-Powered OS for the Security Fabric
Download solution brief FortiOS 8.0 Press Release
The Power of One Operating System
FortiOS is Fortinet’s natively AI-powered and quantum-safe operating system, serving as the foundational engine of the Fortinet Security Fabric platform. By converging networking and security into a single high-performance functional framework, FortiOS eliminates the gaps created by fragmented point products and simplifies management at scale. This unified architecture harnesses the power of AI to drive consistent security policies, seamless user experiences, and real-time visibility across all environments, including on-premises, multi-cloud, hybrid, and converged IT/OT environments. With FortiOS, organisations can finally achieve a truly integrated, machine-speed defence.

Key FortiOS Enhancements
Generative AI Security
Visibility with enhanced FortiView and control of sanctioned vs. unsanctioned AI apps enable safe innovation without exposing sensitive data. AI-aware security enforcement blocks risky actions while allowing sanctioned GenAI tools to accelerate productivity.
MCP and A2A Detection
This detection reveals hidden AI activity by identifying MCP and A2A traffic, giving clear insight into how apps, agents, and tools interact behind the scenes. Enforce safe, governed AI use with precise controls that distinguish sanctioned apps from unsanctioned or risky AI behaviour.
FortiAI-Assist for FortiGate
This AI assistant streamlines troubleshooting with quick diagnoses of firewall issues and guides you to clear, step-by-step fixes. Turn complex Fortinet firewall tasks into easy, conversational instructions, reducing errors and saving valuable admin time.
Unified Agent Enhancements
FortiClient supports PQC for secure VPN connectivity, endpoint risk score for posture visibility and adaptive ZTNA, and detection and control of AI applications and their communications.
Data Lake Enhancements
FortiOS 8.0 consolidates network, endpoint, and identity telemetry into a unified XDR dashboard, using embedded AI agents to automate triage and root-cause analysis. This shift enables machine-speed response and identity-driven detection to neutralise sophisticated attacks earlier in the kill chain.
Enhanced Data Protection
Optical character recognition (OCR) in FortiGuard DLP detects sensitive data in images and scans, ensuring nothing slips past traditional text-based inspection. Stop data leaks across more channels by automatically identifying exposed PII, documents, and screenshots, even when embedded in non-text formats.
Quantum Safe
Enhanced support for NIST-approved algorithms, comprehensive crypto-agility, and SSL deep inspection are included in FortiOS 8.0. This is reinforced by FIPS 204/205-compliant hybrid key exchange protecting critical access paths with quantum-resilient security for management access and agentless VPNs for end-to-end cryptography.
Advanced AI/ML IPS
An advanced on-box AI/ML IPS engine—available across all FortiGate models—uncovers hidden command-and-control activity by detecting attackers exploiting DNS to disguise their traffic.
OT Security
FortiOS 8.0 extends advanced security controls into OT environments with virtual IP (VIP) support for encrypted communications to OT servers. This ensures security and compliance with NERC CIP/IEC 62443 and audit readiness, enhanced IPsec connectivity, and improved segmentation and inspection.
Next-Generation SASE
Our flexible unified SASE solution with multiple deployment options secures access to the internet, private, and SaaS applications for any enterprise, ensuring data governance and long-term cryptographic resilience for SD-WAN.
“There is nothing worse than having a one-off solution that you have to shoehorn into your system to make it work. Fortinet products integrate seamlessly with other Fortinet devices and with security tools from other vendors. This is a clear differentiator for Fortinet—it has only been concerned about one thing: creating a solution that meets our needs and is easy to use.”
– John Maier, Senior Network Engineer, City of Columbia
