I wanted to know how often does the sophos utm security certificates update? Been getting weird errors after installing one they are showing it has expired like 3 years ago.
Certificate management can be very different between OSs, browsers, and even individual apps.
Chrome, like IE, uses the Windows Cert store, unlike Firefox, which stores it's own. Do this (Based on v9 WebAdmin, if using v8 you should be able to figure it out) if this is a windows client:
1) In WebAdmin, download the CA Cert at Web Protection>>Web Filtering>>HTTPS CAs Tab. 2) On your Windows Machine, run mmc.exe, File>>Add/Remove Snap-ins. Add the Certificates snap-in. When prompted, choose Computer Account, then Local Computer. Click OK to access the snap-in itself. 3) Expand Certificates (Local Computer). Expand Trusted Root Certification Authorities and right-click on the certificates "folder">>All Tasks>>Import.... Now import the CA certificate.
What this will get you is that Chrome, IE, and any applications that abide by the windows cert store, will trust this cert for any users that log onto this machine. If this is for a business, the cert can be deployed like this through Group Policy.
