Transport Layer Security (TLS) is a foundation piece of modern Internet security. As the replacement of the earlier (and now deprecated) SSL, TLS encrypts the majority of sessions taking place via a web interface. The new standard went through 28 drafts to reach a production state and some products and services began incorporating TLS 1.3 compatibility over a year before the final version. Despite some concerns of some security professionals, there’s no “back door” into the unencrypted traffic. The real question is how quickly organizations adopt the new protocol.”]
