Install the root certificate on Windows devices
You must install the DNS Protection root certificate on users' devices to ensure they can see block pages.
To install the root certificate on Windows devices, do as follows:
- In Sophos Central, go to DNS Protection > Installers.
- Under Configure block pages, click Certificate to download the root certificate.
- On the Windows device, install the root certificate. See Installing a trusted root certificate.
- Add certificate snap-ins. See Adding certificate snap-ins.
If you're using Firefox, add the certificate as a trusted root certificate or authority. See Setting Up Certificate Authorities (CAs) in Firefox.
