Enterprise-Grade Protection for Smaller Networks
The FortiGate 81F delivers the same application-centric, scalable and secure SD-WAN capabilities as the 80F, with 128 GB of internal SSD storage for on-box logging and reporting. Protects against cyber threats with system-on-a-chip acceleration and industry-leading secure SD-WAN in a simple, affordable, and easy to deploy solution.

The FortiGate-81F-Bypass offers a pair of bypass port pair that helps organizations to avoid network communication interruption due to device faults and improve network reliability.
The FortiGate 81F Series includes a USB port that allows you to plug in a compatible third-party 3G/4G USB modem, providing additional WAN connectivity or a redundant link for maximum reliability.
Designed for small environments, you can place it on a desktop or wall-mount it. It is small, lightweight yet highly reliable with superior MTBF (Mean Time Between Failure), minimizing the chance of a network disruption.
FortiLink protocol enables you to converge security and the network access by integrating the FortiSwitch into the FortiGate as a logical extension of the NGFW. These FortiLink enabled ports can be reconfigured as regular ports as needed.

The FortiGate 81F suits medium-sized offices that need built-in storage for Computer Crime Act log retention. Our team assesses your user count, internet speed and the security features you want enabled before recommending the right model, so you don't overpay or end up with a device that's too small.
The quotation covers the FortiGate 81F unit, the UTP or Enterprise Protection licence bundle for your chosen term, and installation with configuration to your company's policy. All costs are stated clearly up front, with no hidden charges.
Performance is close to the 80F, but the 81F includes 240 GB of built-in SSD for storing logs and reports on the device itself, reducing the need for a separate log server in medium-sized organisations.
Yes. Built-in storage lets you pull historical reports straight from the device — web access, application usage and security events — which are exactly the documents IT auditors tend to ask for.
Yes. The MA contract covers scheduled health checks, firmware updates, policy changes on request, remote and on-site troubleshooting, and handling hardware claims with Fortinet for the life of the contract.
Yes. We configure usage logs to be kept for at least the legally required 90 days — on the device's own storage, an internal syslog server or FortiAnalyzer — with time synced to a verifiable NTP source.
