# Manage TLS Protocol

For MiCollab 8.1 or later, by default, MSL supports the use of TLS v1.2 for communications security. For earlier releases, MSL supports the use of TLS v1.0 by default. To migrate to the latest TLS version, you must upgrade your MiCollab for PC Client and MiCollab for Mobile Client to MiCollab 8.1 or later. After these steps are complete, your system will be compliant with the Payment Card Industry Data Security Standard (PCI DSS).
Note:

- With MSL 10.6 release and later, new installations have the TLSv1.0 protocol disabled by default. The protocol can still be enabled, if required, from the Web Server panel.

- With MSL 12.0 Release, TLS 1.1 and TLS 1.0 are no longer regarded as secure and are not supported by MSL 12.0.
