Subject: Action Required - ArcGIS Security Update


We are making an important configuration change to ArcGIS for TLS support.

Esri is committed to providing strong security for the ArcGIS platform by using the latest industry standards and best practices for security protocols. To meet these industry expectations, we are making an important update to ArcGIS Online in February 2019 that is likely to affect most ArcGIS software and custom solutions. With this change, we are enforcing the use of TLS (Transport Layer Security) version 1.2 only and will remove support for earlier TLS versions 1.0 and 1.1.
More details about Esri’s support for TLS, including patches and instructions for updating software, can be found by visiting
Who is affected?
Users of most ArcGIS software or custom solutions using Esri technology may be affected by this planned update to TLS protocol v1.2.
What do I need to do now?
Go to the Esri TLS Support page for more information and specific actions you may need to take in advance of this update.
If this email is not applicable to you, please forward this email to the one who manages your ArcGIS software or custom solutions using Esri technology.
