Cisco Secure Client
VPN client for Windows/MacOS that supports TLS 1.3 — this Cisco Secure Client version 5. We only need the module Core & AnyConnect VPN. After installing Cisco Secure Client version 5 and launching the AnyConnect VPN client, enter the domain, and then the login and password of the VPN client.
The desktop version cannot be downloaded on the Cisco website for unregistered customers, but it can be found on the Internet:
The client is from Clavister - they make some of their corporate solutions using a protocol similar to AnyConnect/OpenConnect. Since version 1.2.1 OCServ can accept connections from OneConnect.
