Runs locally on your network Built on proven, stable hardware Cancel anytime

Set up in minutes.
Runs silently, always on.

NithShield sits on your home network, watching every DNS request every device makes — on reliable, industry-standard hardware built to run 24/7.

Plug in

Connect NithShield to your router. Pre-configured and ready to go — no terminal, no command line, no IT knowledge required. Just power on and it starts working.

It watches

Every device on your network routes DNS through NithShield. Scam sites are blocked instantly from 568,000+ known threats, with the list updated every night.

You stay informed

Daily family reports, real-time scam alerts, and plain-English anomaly summaries arrive in your inbox automatically — no dashboard required.

Everything your network needs.
Nothing you don't.

Three layers of AI-powered protection, running locally on proven, stable hardware.

Scam & phishing blocking

568,000+ known threat domains blocked at the DNS layer before they even load. Updated every night from OpenPhish, URLhaus, and Phishing.Database. When a device hits 3+ scam domains in 5 minutes, you get an AI-written alert explaining exactly what happened.

Always on

Family wellbeing coach

Every morning at 7am, NithShield analyses your kids' browsing from the night before and sends a warm, plain-English email. Healthy patterns get a thumbs up. Concerning domains are flagged with context, not alarm.

Daily email

AI anomaly fingerprinting

Every device builds a rolling 7-day behaviour profile. Unusual hours, sudden traffic spikes, IoT devices calling unexpected domains — all flagged and explained in plain English, with suggested next steps.

Hourly scans

Privacy mode

The Pro Private edition runs all AI analysis entirely on-device using high-performance GPU hardware. No data ever leaves your home — not even for the AI that powers it.

"I want to know my kids are safe online, without becoming their IT department."

The problem NithShield was built to solve.

Built close to home.

NithShield started as a personal project — a small device on a home network, a question about whether AI could make security genuinely useful for families, and a lot of late nights writing code.

The result is a system that blocks threats, coaches families, and explains what it finds — in language anyone can understand. We're sharing it because every home deserves network intelligence, not just enterprise IT teams.
