If your website's security certificate has been cancelled, it may not be accessible


The Department of Health and Human Services has been made aware that  20,000 website security certificates issued by provider Trustico, have been compromised. This has led to cancellation of these certificates.  As a result, some organisations may not be able to access online services.

Organisations that have installed a website certificate issued by DigiCert from Trustico, may be impacted and their website may not be accessible. Please contact your IT service provider if you are experiencing this issue.

DigiCert, the Secure Socket Layer (SSL) Certificate provider has released a statement regarding the Trustico Certificate revocation. For further information visit:
