Installing the QEHS Certificate: Instructions for Laptops

To be able to use search engines on your school laptop, you will need to install a certificate.

Technical reason: Safe searches are now enforced through our Internet gateway and a self-signed certificate is required to do this. It also means that filter lists work regardless of whether sites use http or https.
