What are the connection security protocols supported by PubNub?
Important Notice: TLS 1.2 Support Requirement Starting February 1st, 2025
Effective February 1st, 2025, PubNub will only support the TLS 1.2 protocol for all communications. The deprecation date for TLS 1.1 is January 31st, 2025, giving you time to update your systems and ensure continuous service.
To prevent any service interruptions, we strongly recommend that you verify and upgrade your systems to support TLS 1.2 or higher as soon as possible, if you haven’t done so already. Regularly monitoring your systems before the deprecation date will help ensure a smooth transition. This upgrade is essential to maintaining the security, reliability, and performance of your PubNub integration.
To assist you, we have provided a test endpoint where you can check your system's compatibility with TLS 1.2: pubsub-tls12-test.pubnub.com.
Please note that PubNub cannot control which TLS version your systems use, so it's critical that you ensure they are updated appropriately.
If you have any questions or need further assistance, feel free to reach out to us at support@pubnub.com.
