Hi All,

How can I verify Tls 1.2 is enabled on all computer across the organization? I do have a GPO but I don't think it applies to all, is there a report or something I can run to verify tls 1.2 is enabled?

Thanks

    Hi,

    TLS 1.2 is enabled by default on Windows 10, version 1507+ and Windows Server 2012+.

    Protocols in TLS/SSL (Schannel SSP)
    https://learn.microsoft.com/en-us/windows/win32/secauthn/protocols-in-tls-ssl--schannel-ssp-

    If you want to verify this, the easiest would be to create a PowerShell script that checks the Windows registry setting over here:

    • HKLM SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols

    Best regards,

    Hi,

    You could either enable tls 1.2 in internet options - advanced or registry. You may refer to this article
