Fortinet has designed our FortiCare support and FortiGuard services to be continuous. When a customer does not renew by the expiration date, then a lapse in the service period occurs. Any lapses in service will require coverage back to the contract expiration date in order to maintain continuous service coverage. There is a 10–day grace period, which is the number of days after the contract expiration date before the lapsed service period coverage goes into effect. If a contract is purchased and registered within the 10–day grace period, then the contract starts on the date of registration.
There is a maximum back date coverage of six months. In other words, if the coverage has lapsed for more than six months, then out of a one–year renewal contract, six months will be used to cover the lapse in service and then the remaining service time will be used to provide continuing service.
