Transport Layer Security (TLS) certificates, formerly known as Secure Sockets Layer (SSL) certificates, are digital certificates that keep your internet connection safe by encrypting the data between your web browser, the website and its server.

The TLS service provides a cost advantage over purchasing it direct from a commercial certificate authority. Other benefits include:

• The site validation process for the utoronto.ca or toronto.edu domains is completed.
• There is no cost charged back to the individual department or division for most certificate products.
• Notification of imminent certificate expiry is provided at least two weeks before the expiry date.
• Information Security adds a departmental contact vetting process to ensure authorization to use server certificates.
• Automatic certificate renewal (ACME) is available for this service.
