About Transport Layer Security (TLS) certificates

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

What does this cost?

Most certificate products are covered under a single agreement maintained by the Office of the CIO, so there is no chargeback to other departments or divisions for orders.

Who can manage obtaining these certificates?

Information Security, part of ITS, facilitates the purchase of Sectigo (formerly known as Comodo Group) TLS certificate products for University server administrators.

The service now provides delegated certificate ordering and management capability with Sectigo Certificate Manager. If your unit is interested in managing its own certificate products, please contact security.admin@utoronto.ca.

What are the benefits of using this service?

The service provides advantages over purchasing it direct from a commercial certificate authority (CA). 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.
