Introduction

Many enterprises find themselves with locations where a small network exists and needs to be secured, but where it is unnecessary or cost prohibitive to deploy a firewall appliance. In those situations, security can be extended to the site in question from a centralized location, leaving only a "thin edge" of networking equipment at the site, while security actions are performed elsewhere.

The FortiExtender SASE solution, branded as FortiBranchSASE (FBS), offers secure and reliable connectivity by integrating with Fortinet's FortiOS through FortiSASE or remote FortiGate devices.

FortiBranchSASE ensures comprehensive connection at the thin edge. As part of the FortiExtender product family, FortiBranchSASE extends the reach of the Fortinet Security Fabric, bringing advanced networking and security capabilities to even the most remote or small office environments.
