Organizations should be aware of an important update to TLS. TLS 1.2 is the most recent update that builds on top of TLS 1.0 and TLS 1.1 to increase network security. Updating your browsers and OS to TLS 1.2 is imperative in order to maintain access to WPA2-Enterprise and onboarding software. Moving away from TLS 1.0 and 1.1 is recommended for a variety of security reasons, not just for WPA2-Enterprise, so we recommend everyone deprecates the older protocols.
