For a managed service provider, DNS filtering is one of the easiest security services to add to a client stack: no agent to deploy, one settings change per site, and a clear report that shows clients what was blocked. These guides cover the business side as well as the technical.
DNS filtering for MSPs walks through multi-tenant setup, per-client policies, white-label branding, PSA and SIEM integration, and common pricing models and margins. If you're moving clients off another service, the comparison guides cover Cisco Umbrella's end-of-life dates and DNSFilter's published pricing.
The firewall setup guide also works as a handout for technicians rolling DNS filtering out across client sites, with the steps for FortiGate, Meraki, UniFi, pfSense and SonicWall in one place.
