Enhanced security network access uses Secure Sockets Layer (SSL) as a protocol that helps ensure the privacy of documents transmitted over the Internet, including email messages. Once activated, SSL encrypts your incoming messages, ensuring that passwords and other private information can not be intercepted in transit.
Activating SSL in Thunderbird is quick and easy, and CNS strongly recommends that you do so.
