Esri is committed to building and providing strong security for ArcGIS by using the latest security protocols. We strive to implement the highest industry standards, including Transport Layer Security (TLS), for data integrity and network security.  

To meet these standards, Esri is making software updates across ArcGIS to support TLS 1.2. As part of improving ArcGIS Online security, Esri is planning to require TLS 1.2 connections for ArcGIS Online services. Action is required to ensure continued access to these services.
