Fortinet FortiGate 51G AI-Based Inline Malware Prevention, 1-Year (FC-10-GT51G-577-02-12)

Signature-based scanning catches the malware it has already cataloged. The first-seen file with no known hash is where it struggles. The FortiGate 51G 1-Year AI-Based Inline Malware Prevention Service (FC-10-GT51G-577-02-12) closes that gap on a FortiGate 51G, applying machine-learning models that inspect files inline and return a verdict in well under a second, so unknown and zero-day malware is blocked in real time before it lands. It is a subscription license only, with no hardware and worldwide electronic delivery.

What this service adds

Inline Malware Prevention widens the 51G’s anti-malware coverage from known threats to unknown ones, without waiting on a sandbox detonation cycle:

• Real-time inline verdicts: files are judged as they cross the firewall, and malicious ones are stopped on the spot rather than flagged after delivery.
• AI and machine-learning detection: models trained by FortiGuard Labs recognize the traits of malware they have never seen, including newly built variants.
• Zero-day and unknown-file focus: the service targets the exact category signatures miss, the first-seen sample with no known hash yet.
• Sub-second decisions: verdicts arrive fast enough to keep inline blocking practical on a live link, so protection does not slow the connection.

Who needs the standalone service

This license fits when inline prevention against unknown malware is the specific layer being added to a 51G that already carries other coverage, such as an active IPS or antivirus subscription and a FortiCare contract. It is the right buy when you want to bolt real-time zero-day blocking onto an existing deployment rather than re-buying a whole bundle. If the 51G has little active protection yet, a bundle is the more economical starting point.

Standalone service vs. the subscription bundles

AI-Based Inline Malware Prevention is bundled only at the Enterprise tier; it is not part of the ATP or UTP packages, which rely on cloud sandboxing for unknown-threat detection instead. Buying this license adds the inline prevention layer on its own. The table below shows where this service sits and what each bundle tier includes around it:

If the goal is to put the 51G on full coverage, the Enterprise subscription (FC-10-GT51G-809-02-12) already includes this inline prevention service in its scope, while the UTP subscription (FC-10-GT51G-950-02-12) covers the broad web and network layers without it. This standalone license is the way to add inline prevention to a device you do not want to move onto Enterprise.

Activation and delivery

The license is issued electronically and registered to a specific FortiGate 51G by serial number. Once applied, the inline malware models and updates push to the appliance for the full twelve-month term. Nothing ships, and a valid 51G is required before activation.
