Content filtering is a process that manages or screens access to specific emails or webpages based on theircontent categories1. Content filtering can be used by organizations to control content access through their firewalls and enforce corporate policies around information system management2. A SOHO client may have content filtering enabled on their network and may need to adjust it to allow access to a corporate website that is blocked by default. The client can use a software program, a hardware device, or a subscription service to configure the content filtering settings andwhitelist the desired website2.
