SN VPN Client Standard 6.87 build 108

Major changes since version 6.64

Exclusive support for Windows 11 and Windows 10 64-bit on Intel processors

SN VPN Client Standard is optimized for Windows 11 and Windows 10 64-bit and can only be installed on these Operating Systems. Version 6.64 of the SN VPN Client Standard is still available and supports Windows 10 32-bit, Windows 7 and Windows 8 (32/64-bit) on Intel processors.

Compatibility of configuration files

IMPORTANT
VPN configuration files from previous versions of the SN VPN Client Standard cannot be imported into this version once it is installed. If a previous version is already present, this installer will automatically convert the previous configuration and import it into the new version.

When upgrading from a previous version, we therefore recommend that you do not uninstall the previous version before you launch the installer.

Gateway certificate check

By default, the gateway certificate will be checked each time a tunnel is opened. It may be necessary to import the complete chain of certification authorities (CAs) to authenticate the gateway, either into the Windows store or into the VPN configuration file.

You can change this default behavior, though we do not recommend doing so (Options menu -> PKI Options).

End of support for "weak" algorithms

For security reasons, this version no longer supports the following algorithms: DES, 3DES, MD-5, SHA-1, DH 1-2, DH 5. If a previous configuration contains one of these algorithms, the installer will convert them to "auto" (automatic negotiation with the gateway).

If the gateway only supports this type of algorithm, you will not be able to establish a connection with this version of the SN VPN Client Standard.
