FAQ
DNS security, answered.
What is Guardino DNS?
Guardino DNS is the flagship product of Guardino Technologies — a DNS-layer security and cognitive-protection service. Your devices send DNS queries to Guardino, which applies your blocklists and policies and returns resolved or blocked answers, over encrypted DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT), with zero query logging.
What is the difference between DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT)?
Both encrypt DNS queries so they cannot be read or tampered with in transit. DoH sends DNS over the HTTPS port (443), blending with normal web traffic; DoT uses a dedicated TLS port (853). Guardino DNS supports both, so you can deploy whichever fits your network and devices.
What is RPZ filtering?
A Response Policy Zone (RPZ) lets a DNS resolver block or rewrite answers based on policy. Guardino DNS uses an RPZ blocklist engine, tuned for cognitive threats, to stop malware command-and-control, phishing, trackers, and manipulation at the protocol level — before traffic reaches your network.
Does Guardino DNS log my DNS queries?
No. Guardino DNS is zero-log: it does not store the people behind queries, does not build profiles, and never sells or shares DNS data with advertisers or data brokers. Privacy by design — we protect, we do not watch.
How do I deploy Guardino DNS?
Point your devices, router, or network at the Guardino DoH/DoT resolver. The RPZ blocklist engine filters threats in real time and threat intelligence updates continuously. Enterprises integrate with AD/Entra ID via SAML and SCIM; ISPs and governments can deploy on-prem or in a sovereign cloud.
Who is Guardino DNS for?
Enterprises (internal device protection with directory integration), ISPs and carriers (network-level filtering with sovereign data flow), governments (on-prem or sovereign-cloud deployment), and families (protection without app installs).
