KeyShield can act as a RADIUS Accounting client – we inform active network elements (FortiGate, Cyberoam, SonicWall, SmoothWall, LightSpeed, LiteSpeed, etc.) about the identity of the user. KeyShield can also act as a RADIUS Accounting server – in which it obtains information about the identity of the user from a firewall or Wi-Fi access point after successful authentication into a VPN.
