EDR End of Support for TLS 1.1 and 1.0

General reminder in response to our original post SentinelOne will no longer support Transport Layer Security (TLS) 1.1 or 1.0 for Agent to Management Console communication.

After April 31st 2023 the Management Console will not connect with or upgrade these Agents. To uninstall or upgrade these Agents after this date, you must access the endpoint with other tools and run our latest Agent installer on the endpoint.

Note: This change does not impact Endpoints running the Windows Legacy Agent.

Until now, SentinelOne continue to support TLS versions 1.0 and 1.1 to keep backward compatibility for Agents on Endpoints that run old operating systems or are difficult to update. At this time, SentinelOne sees very low numbers of such Endpoints used by their customers. Also, many customers ask that SentinelOne deprecate these protocols to simplify their regulatory compliance processes. SentinelOne feel this is the right time to retire these protocols.

To prevent any security impact, SentinelOne recommend Partners to install the relevant software updates to enable TLS versions 1.2 and 1.3.

See Agent Requirements for Windows and Supported Transport Layer Security (TLS) Cipher Suites for more information.

See this Microsoft article, for instructions on how to update your Windows OS to TLS 1.2.
