Decision notes

DNSFilter pros and cons

Potential strengths

  • Works at the DNS layer, so it can block threats before a connection is even established — no endpoint agent required on every device.
  • Cloud-managed and designed for scale, making it practical for MSPs securing multiple client networks or enterprises with distributed locations.
  • AI-driven threat detection helps keep the block lists current without relying solely on manual signature updates.

Points to verify

  • Confirm that DNS-level blocking fits your overall security stack — it works well as a first layer but does not replace endpoint protection, email security, or web application firew...
  • Check how the content filtering categories align with your organisation's acceptable-use policy — you may need granular control over which categories are blocked for different user...
  • Review the reporting and alerting capabilities to ensure they integrate with your existing SIEM or monitoring tools for incident response.
