| Compare | ||
|---|---|---|
| Verdict | Depends | Worth it |
| Best for | Mid-size and large IT teams | Households wanting network-wide ad/malware blocking |
| Who it's not for | Small teams . a router filter or DNSFilter suffices | Anyone expecting VPN privacy. This is DNS filtering, not a VPN |
| Privacy | Several CVEs from 2022-2026 (auth bypass, privilege escalation); Cisco publishes advisories and fixes.12 | No known public vulnerabilities found in the sources reviewed. |
| Support quality | No support evidence in sources | Reddit reports poor service attitude |
| Public sentiment | Active G2, PeerSpot, and r/sysadmin threads show users publicly questioning its cost and weighing alternatives.³ | Enthusiasts switching from NextDNS are mostly satisfied, but latency, smart-TV buffering, billing, and support complaints recur.15 |
| Biggest gotcha | Quote-only pricing; costs vary per deal . get competing bids before signing⁶ | Per-device pricing multiplies fast across many gadgets; HN commenters flag cost vs rivals |
