Fortinet FortiGate 51G-5G AI-Based Inline Malware Prevention, 1-Year (FC-10-F51G5-577-02-12)

A FortiGate 51G-5G usually sits at the far edge of the network, on a cellular link, with no analyst watching it minute to minute. That is exactly where a brand-new malware sample, one no signature has catalogued yet, has the best odds of slipping through. The FortiGate 51G-5G 1-Year AI-Based Inline Malware Prevention Service (FC-10-F51G5-577-02-12) answers that risk: for twelve months it applies FortiGuard machine-learning models that inspect files inline and return a verdict in a fraction of a second, so unknown and zero-day malware is stopped before it reaches the host. It is a subscription license only, with no appliance included and electronic delivery worldwide.

What this service adds to the 51G-5G

Inline Malware Prevention extends the firewall’s anti-malware reach past the threats it already knows, and it does so without holding traffic for a sandbox round trip:

• Real-time inline verdicts. Files are judged as they pass through the 51G-5G, and anything malicious is blocked at that moment instead of being flagged after it has already arrived.
• AI and machine-learning detection. Models built by FortiGuard Labs read the characteristics of malware they have never encountered, catching freshly compiled variants and repacks.
• Built for the first-seen file. The service is aimed at the precise category signatures miss, the sample with no known hash, which is the one most likely to be a real intrusion attempt.
• Sub-second decisions. Verdicts come back fast enough that inline blocking stays practical even on a 5G WAN where every bit of added latency is noticeable.

Who should buy the standalone license

This SKU makes sense when inline prevention is the one missing layer on a 51G-5G that already runs other protection, say an IPS or antivirus subscription plus a FortiCare contract, and you want to add zero-day blocking without re-purchasing a full package. If the device has little active security on it yet, a bundle is usually the cheaper way in, since it brings IPS, antivirus, and web controls along with it.

Standalone service vs. the subscription bundles

AI-Based Inline Malware Prevention is included only in the Enterprise tier. The ATP and UTP packages do not carry it; they lean on cloud sandboxing for unknown-threat detection instead. Buying this license adds the inline layer by itself. The table below shows where the service falls and what each tier wraps around it:

If the plan is to put the 51G-5G on full coverage, the Enterprise subscription (FC-10-F51G5-809-02-12) already folds this inline prevention service into its scope, while the UTP subscription (FC-10-F51G5-950-02-12) covers the broad web and network layers without it. Reach for this standalone license when you want inline prevention on a device you are not ready to move onto Enterprise.

Activation and delivery

The license is issued electronically and registered to a specific FortiGate 51G-5G by serial number. Once it is applied, the inline malware models and their updates stream to the appliance for the full twelve-month term. Nothing ships, and a valid 51G-5G has to be in place before the service can be activated.
