What are the connection security protocols supported by PubNub?
Starting February 1st, 2025, PubNub will only support the TLS 1.2 protocol for all communications. The official deprecation date of TLS 1.1 is January 31st, 2025. This gives our clients time to transition their systems and ensure uninterrupted service.
To avoid any disruption, we highly recommend that you verify and upgrade your systems to support TLS 1.2 if you haven’t already. This transition is critical to maintaining the security, reliability, and performance of your PubNub integration.
It’s important to note that PubNub does not have control over the TLS version your systems use.
