When a Fortinet license expires, your FortiGate keeps routing traffic and running basic firewall and VPN functions, but it stops receiving FortiGuard security updates, FortiCare technical support, and firmware upgrades. In short, the appliance keeps forwarding packets while its threat protection quietly goes stale.
A lapsed license is a stressful moment for any IT team, but it does not have to mean downtime or overpaying. This guide explains exactly what stops working, how Fortinet’s backdating policy affects the price you pay, and a clear step-by-step plan to renew fast.
An expired Fortinet contract does not brick your firewall. The device will not shut down or stop passing traffic. What you lose is everything that keeps it current against new threats. Here is the split at a glance:
| Still works after expiry | Stops the day it expires |
|---|---|
| Routing and existing network functions | FortiGuard updates — antivirus, IPS, web & DNS filtering, application control |
| Client-to-Site and Site-to-Site VPN | FortiCare technical support and RMA hardware coverage |
| Basic firewall policies already configured | Firmware and security-patch upgrades |
In short, your FortiGate becomes a static firewall. It can still filter traffic on old rules, but it loses the ability to protect you from the newest cyber threats. Here is what that means in practice:
Need to bring coverage current across several devices? Our Fortinet licensing & renewals desk quotes any FortiGuard, FortiCare, or bundle SKU, and if the unit is end-of-life we will map an upgrade path instead.
Send us your FortiGate model or serial number. As a Fortinet Select Partner & MSSP we quote any renewal and deliver the key electronically worldwide, usually within one business day.
This is the part that surprises most IT buyers: when you renew an expired license, the new contract can be backdated, so you may pay for time the device was not actually covered. It is built on Fortinet’s ‘continuous support’ principle — renewals are meant to start the day after the last contract ended so there is no gap on record.
You can review the exact start and end dates in the Fortinet Support Portal before you pay, so there are no surprises. The practical takeaway: the longer a 1-year license sits expired, the more you pay for nothing — renew promptly, or move to a multi-year term to skip the penalty.
Renewing an expired Fortinet license is straightforward when you work in this order:
We are a Canada-based Fortinet Select Partner & MSSP, FCP-certified, with instant worldwide license delivery. Renewals are quoted fast and delivered electronically in 0 to 1 business day, so an expired contract does not stay expired for long.
Yes. The FortiGate keeps routing traffic and enforcing the firewall and VPN rules already configured. What stops is FortiGuard security updates, FortiCare technical support and RMA, and firmware upgrades, so protection against new threats goes stale.
For a 1-year renewal, Fortinet backdates the new contract up to a maximum of six months so coverage stays continuous, which means a long-expired license loses the time beyond that window. Multi-year renewals often waive backdating and run from your registration date.
You can renew after expiry at any time, but the backdating penalty on a 1-year term grows with the gap. The hardware is not retired unless the model itself is end-of-life, in which case an upgrade path is the better move.
No. A reboot is not required. Once the contract is registered to the serial number, the entitlement applies automatically and the new expiry date appears in FortiCloud and on the device dashboard.
Yes. Fortinet licenses are electronic entitlements with no geographic restriction. DataCenter360.ca delivers the registration key worldwide, typically within one business day.
Once the renewal is registered, FortiGuard resumes pushing updates and FortiCare support and RMA are reinstated for the covered term. There is no waiting period beyond registration.
After a lapse, multi-year is often cheaper: Fortinet frequently waives backdating on multi-year contracts, and you remove the annual renewal task that causes lapses in the first place.
Skip the backdating guesswork — we confirm your exact coverage dates and price before you pay.
