Encrypted DNS (DoH)
DNS‑over‑HTTPS with a unique endpoint URL issued per user, so your queries travel encrypted and arrive already identified as yours.
Encrypted DNS filtering, built for one household at a time.
Sentry53 gives your home a private, encrypted DNS endpoint and filters what it resolves against a policy you control — categories, profiles for kids, teens and adults, and your own allow and block lists on top.

Why Sentry53
A resolver that answers to your policy, not a default one.
Every device on your network asks a DNS resolver where to find things. Sentry53 is that resolver — reached over an encrypted endpoint that belongs to you, and told what to do by a policy you wrote.
- A private endpoint, issued to your household
- One policy, applied to every device on it
- Your own allow and block lists on top
The product
Four things it does, and does plainly.
Category filtering
Per‑household policy over content categories, evaluated on every query, with the verdict and the reason recorded in your query log.
Kids, teen, adult profiles
Pick a named profile instead of toggling hundreds of categories. kids is the strictest; teen relaxes it; adult keeps the security categories and drops content filtering.
Your lists win
Explicit allow and block lists sit above the category engine. If you name a domain, that decision overrides whatever the category says.
Profiles
Three settings, not three hundred.
kids
Blocks the sensitive‑topic categories plus gambling, anonymizers, ads, dating and the security categories.
teen
kids with a few of the stricter topics relaxed.
adult
Keeps only the security categories — protection without content filtering.
Straight answers
The questions worth asking a DNS filter.
Including the ones where the honest answer is “no”.
