Security Certificates Service


Security or digital certificates provide a mechanism to permit end users to establish secure communication channels with the owner (subject) of the certificate. Such certificates can be issued to a variety of subjects, but are most typically are used by servers to secure web services as part of the HTTPS protocol - a TLS/SSL server certificate.

For anyone requiring a TLS/SSL server certificate, it is recommend in the first instance, to consider using a free and automated renewal service, such as Let's Encrypt.

There are many situations where it is not possible or appropriate to implement automated certificates services. In these cases, the ITS Security Certificate Service can be utilised.
