ArcGIS TLS Security Update Patches
TLS Security Updates
To maintain the highest industry standards for data integrity and network security, Esri is making an important configuration change to ArcGIS Online – requiring the use of TLS 1.2 connections.
What is TLS?
TLS or “Transport Layer Security” is a widely deployed network security protocol. It facilitates privacy and data integrity between communicating applications over a network. You use TLS whenever accessing ArcGIS Online services, such as basemaps, geoprocessing services, and the Living Atlas, from ArcGIS Desktop, ArcGIS Enterprise, and other applications.
What does this mean to me?
You may need to apply a patch to your software – to ensure the use of TLS 1.2 connections.
