Following the announcement on November 10, 2023, we are continuing our transition to requiring TLS 1.2 or later for all connections to Azure services. To minimize disruption to customer workloads, several services will continue supporting TLS 1.0 and TLS 1.1 versions and complete their transitions by August 31, 2025 when TLS 1.2 or later will be required for all connections to Azure services (unless explicitly indicated in service documentation). The list of remaining services will be updated as transitions to TLS 1.2 or later complete.
While the Microsoft implementation of TLS 1.0 and TLS 1.1 versions is not known to have vulnerabilities, TLS 1.2 or later versions provide improved security features, including perfect forward secrecy and stronger cipher suites.
Customers still using TLS 1.0 or 1.1 should transition their workloads to TLS 1.2 or later versions to ensure uninterrupted connectivity to Azure services.
Recommended action
To avoid potential service disruptions, confirm that your resources that interact with Azure services are using TLS 1.2 or later. Then:
- If they're already exclusively using TLS 1.2 or later, you don't need to take further action.
- If they still have a dependency on TLS 1.0 or 1.1, transition them to TLS 1.2 or later.
