Depends
Confidence: Medium

| Compare | ||
|---|---|---|
| Verdict | Worth it | Depends |
| Best for | Privacy-minded households | Mid-size and large IT teams |
| Who it's not for | Organizations needing SLAs, compliance docs, or a vendor security page | Small teams . a router filter or DNSFilter suffices |
| Privacy | No known public vulnerabilities found in the sources reviewed.12 | Several CVEs from 2022-2026 (auth bypass, privilege escalation); Cisco publishes advisories and fixes. |
| Support quality | No support-quality evidence in reviewed sources | No support evidence in sources |
| Public sentiment | Users praise set-and-forget ad blocking and deep configurability, but a vocal minority cite trust concerns and free-tier limits.⁵ | Active G2, PeerSpot, and r/sysadmin threads show users publicly questioning its cost and weighing alternatives. |
| Biggest gotcha | 300k monthly query cap on free tier; busy households exceed it fast² | Quote-only pricing; costs vary per deal . get competing bids before signing |
