Fortinet Adds Inline AI Security to Existing Firewalls

Live Poll

Do you trust integrated security platforms to protect your organization's sensitive data from AI-related threats?

Fortinet has released its FortiGuard Inline AI Security Service, a cloud-delivered tool designed to provide guardrails for enterprise AI deployments. The service integrates directly into existing FortiGate firewalls to monitor prompts and responses in real time.

Why it matters

As enterprises increase AI adoption, existing security tools often lack the capability to inspect prompts or model outputs for leakage. This service bridges that gap by applying data loss prevention directly within the established network security stack.

The system monitors 35 distinct categories of personally identifiable information and supports 50 predefined compliance policies. It operates by intercepting and inspecting prompts, responses, and tool calls in real time to enforce security policies.

The players

Fortinet

A cybersecurity firm based in Sunnyvale, California, known for its FortiGate firewalls and a portfolio of network security solutions used by over one million customers.

The details

The service functions as a cloud-delivered layer that integrates with existing FortiGate firewalls, allowing organizations to manage AI security without deploying additional hardware. It uses the FortiAIGate control point, which leverages technology from the company’s acquisition of Virtue AI, to govern communication between users and large language models. The architecture supports self-hosting on Kubernetes using NVIDIA GPUs, ensuring that data loss prevention policies can be enforced locally on-premises.

Fortinet announced the FortiGuard Inline AI Security Service on October 26, 2026.

The Tech Race

This release marks a shift toward embedding AI-specific security directly into established network infrastructure rather than treating AI tools as an isolated ecosystem. It moves Fortinet into direct competition with specialized AI governance platforms by leveraging its existing footprint of over one million customers.

Security administrators can now apply AI-specific inspection policies to existing FortiGate firewalls without purchasing additional security hardware. The service is available immediately for organizations seeking to manage shadow AI and enforce data privacy at the network level.

The takeaway

The move signals that network security providers are prioritizing the inspection of generative AI prompts as a standard defensive requirement. Administrators should evaluate their organization's specific compliance needs against the 50 predefined policies to determine how this tool integrates with current data loss prevention workflows.
