Blocking happens before the page loads
Every time your device visits a website, it first asks a DNS server for the address. DNS-SHIELD intercepts that question — harmful sites never get an answer and never load.
You visit a site
Your browser or app tries to load any website on any device.
DNS query sent
Your device asks DNS-SHIELD: what is the IP address of this domain?
Checked against 8 categories
DNS-SHIELD checks the domain against millions of known harmful sites, updated daily.
Safe sites resolve, bad ones block
Clean domains get an answer. Harmful domains get nothing — the page never loads.
Three secure protocols — all supported
The standard protocol. Works with all routers and devices. Recommended for network-wide setup.
Encrypts DNS queries so your ISP cannot see which sites you visit. Use this on Android Private DNS.

Your privacy is the whole point
Existing DNS filters either track you, sell your data, or are hosted in the US. DNS-SHIELD was built as an alternative that takes none of those shortcuts.
Zero query logging
We never record which domains you or your family visit — not in aggregate, not per user, not ever.
No IP storage
Your IP address is never written to disk. Requests are processed in memory and immediately discarded.
Aggregate stats only
We track total blocked and allowed query counts. We never log individual requests, sessions, or users.
Canada-hosted
All infrastructure runs in Canadian data centres. Your data never leaves Canadian jurisdiction.
PIPEDA compliant
Designed from the ground up to comply with Canada's Personal Information Protection and Electronic Documents Act.
Open source
Every line of code is public on GitHub. Any researcher, auditor, or citizen can verify exactly how DNS-SHIELD works.
Open source & built for Canada
DNS-SHIELD is completely free. Set it up once — it works silently in the background forever.
