## Our take

What our shortlists say about the one we picked.

### [Fortinet FortiClient](https://cybersectools.com/tools/fortinet-forticlient)

Best for: Companies already running Fortinet firewalls

It earns its place because Fortinet firewalls use its device data to enforce access rules, so one agent handles endpoint protection and access control at once. If you already run FortiGate, that can replace a separate VPN client and endpoint agent. If you do not, weigh it against focused endpoint suites, because much of its value depends on the firewall side.
