DNS Fortress · Private home DNS

Private, protected internet for your whole home.

Ads, trackers, phishing pages and known-malware domains simply never load — stopped at the door, on every device in the house.

A self-hosted guardian that sits between your home and the internet — encrypting your DNS, blocking the bad stuff, and quietly learning from GuardDex.

What is the DNS Fortress?

Every app and device in your home asks "where do I find this website?" hundreds of times a minute — that's DNS. Normally those questions go to your ISP in the clear, logged and sold. The Fortress answers them for you instead: it blocks the dangerous and annoying ones, sends the rest out encrypted and anonymized, and protects every device at once — phones, tablets, the smart TV, and the gadgets that have no security of their own. It runs on your own hardware, never Big Tech's.

What it does

Protection at the front door — covering the whole household, not one browser.

🏠

Whole-home protection

Point your router at it once and every device is covered — including the ones you can't install anything on.

🚫

Blocks ads & trackers

~95% coverage of ads, trackers, telemetry, cryptominers and scam domains — using the best community blocklists, refreshed automatically.

🔒

Private, encrypted DNS

Your lookups leave the network encrypted (DoT/DoH) and mixed through anonymizing relays — so no ISP or broker can log or sell where you go.

🎣

Stops phishing & malware

Known phishing, brand look-alikes, freshly-registered scam domains and malware callbacks never resolve — blocked before a byte loads.

🧅

Optional Tor egress

Route your DNS out over the Tor network for maximum anonymity, with a single toggle.

♻️

Self-healing

Real health checks plus auto-restart mean a hiccup recovers on its own — it never silently leaves you exposed.

🧠 Backed by the GuardDex brain

A blocklist only knows yesterday's bad domains. Connect the Fortress to GuardDex with one API key and it becomes a living shield.

Monitors every lookup

GuardDex watches every domain your home resolves, in real time.

Scans the new ones

Each new domain is checked against GuardDex's threat intelligence, phishing brand database, IP-reputation engine and AI scam-language detection.

Auto-blocks what's bad

A malicious verdict is pushed straight back to the Fortress — so the next device that asks is already protected.

Tells you what it caught

You get a plain-language alert (push / email / SMS) — including which device triggered it — and a trusted Guardian can be looped in.

Why run a Fortress

Most DNS blockers stop at ads. This one is a hardened, honest, whole-home guardian.

Protects the people you love

One switch shields the kids, the grandparents and every gadget — especially the people scammers target most.

Truly private

Encrypted, anonymized DNS means your every click isn't logged, profiled and sold.

It tells the truth about itself

A built-in verifier audits the Fortress and gives an honest verdict — HEALTHY / DEGRADED / BROKEN — so you're never fooled into a false sense of safety.

DNSSEC-validated

Forged DNS answers are rejected, so you reach the real site — not an attacker's look-alike.

Yours to control

Self-hosted on a Raspberry Pi or any Linux box, bound to your home and Tailscale mesh only — never an open resolver.

Real people behind it

Built and supported by David & Stephanie Richey — you can actually reach us.

Verify, don't trust

Run one command and get a full audit — control checks, DNSSEC, encrypted transports, per-category block coverage, latency, and a clear verdict.

Honest verdict

HEALTHY / DEGRADED / BROKEN with an exit code — a non-resolving Fortress is flagged, never falsely reported as "100% blocked."

🔐

DoT & DoH

Encrypted DNS-over-TLS and DNS-over-HTTPS for your devices and apps that support it.

🧱

Layered stack

Technitium → validating Unbound → DNSCrypt anonymized relays → optional Tor. Defense in depth.

🛠️

One-command install

An installer auto-detects your network, generates its own secrets and certificate, brings it up and verifies it.
