I am getting vulnerability warnings from NIST, which indicate I need to
be using version 7.4.4.x of FortiClient, but your website does not
provide beyond version 7.4.3.1761 for the VPN only version. Please
provide an update for the VPN only version.

I am unsure why Fortinet continues to sell the FortiGate product with
the benefit of a free app for VPN access and then refuses to update the
app when known vulnerabilities in the app are discovered.
