    How to manage SSL/TLS ciphers and protocols in Plesk for Windows?
    For example, disable insecure ciphers and enable more recent ones.

    Answer

    Note: Plesk does not provide build-in functionality to manage SSL/TLS ciphers on Windows server. Use Windows utilities or 3rd-party applications instead. TLS 1.3 is supported on Windows Server 2022 only.

    Using Windows utilities

    1. Connect to the server via RDP.

    2. Go to Start > Edit group policy.

    3. Go to Local Computer Policy > Computer Configuration > Administrative Template > Network > SSL Configuration Settings > SSL Cipher Suite Order.

    4. Set option Enabled.

    5. Edit SSL Cipher Suites in the line.

    6. Press OK to apply changes.

    Using a 3rd-party application

    1. Connect to the server via RDP

    2. Download free utility IIS Crypto and launch it

    3. Open tab Schannel

    4. Select the version of the protocol to enable/disable

    5. Click Apply:

    6. Reboot the server
