GuardDex guards every app on the phone — blocking scam links and fake websites before they can do harm, and explaining the danger in plain English.
Built especially for parents and grandparents who are the favorite targets of today's scammers — with a quiet way to loop in a trusted family member.
GuardDex is a privacy-first security app for Android that sits between the phone and the internet. It watches the links, messages, and websites a person runs into every day, stops the dangerous ones, and turns confusing tech threats into clear, calm warnings anyone can understand. No data is sold, nothing is tracked — it runs on our own servers, not Big Tech's.
Layered protection that covers the whole phone — not just one browser.
Blocks known phishing and malware sites across every app — texts, email, browsers, social media — not just one. Runs quietly in the background.
Checks links and websites against a 44-brand impersonation database plus live AI analysis, catching fake bank, delivery, and "tech support" pages.
Reads suspicious texts and warns in plain language — "this looks like a gift-card scam" — and can check whether a phone number is fake or VoIP.
A built-in browser that scans pages as you go, blocks ads and trackers, upgrades to HTTPS, and strips fingerprinting.
Watches notifications from all apps and flashes a warning before a dangerous link is ever tapped.
A trusted family member can be quietly notified when something risky happens — so no one faces a scam alone.
Set it up once. It protects in the background from then on.
A short guided setup turns on DNS Shield and notification protection. No technical knowledge needed.
As the phone reaches out to websites, GuardDex checks each destination against its threat lists — and silently blocks the bad ones.
Suspicious URLs and texts are analyzed by AI and matched to known scam patterns, then explained in plain English.
Instead of a confusing error, the person sees a calm, readable warning telling them what's wrong and what to do.
If set up, a trusted family member gets a gentle heads-up — or the person can tap "Ask my Guardian" for help.
Most security apps are built for IT departments. This one is built for your family.
Scammers target seniors hardest. GuardDex is designed to protect them without overwhelming them.
Warnings say what's happening in words anyone can understand — no error codes, no panic.
Your data isn't sold or mined. GuardDex runs on Richey Business servers, not Big Tech's.
The guardian feature means you can quietly help a loved one stay safe, from anywhere.
DNS Shield covers every app at once — not just a single browser you have to remember to use.
Built and supported by David & Stephanie Richey — you can actually reach us.
Going further than a typical security app.
An optional full-tunnel WireGuard VPN routes traffic through a private exit for extra privacy on public Wi-Fi.
Detects inaudible "ultrasonic beacons" some apps and ads use to track you across devices.
Checks whether household members' emails have shown up in known data breaches, and watches for new ones.
Shows where your personal information may be listed by data brokers so you can request removal.
The same link-scanning and ad/tracker blocking for Chrome & Firefox on the desktop.
Plain-language alerts about the scams making the rounds, so your family knows what to watch for.
Not just defense. GuardDex lets you safely test your family's resilience — and your own setup — so weak spots show up in a drill, not a real attack.
21 attack simulations — phishing pages, network attacks, payloads, and recon — run in a controlled lab so you can see exactly what a real attacker would try.
Send a consented practice scam to a loved one — even a realistic fake Google or Facebook login. If they'd have typed their password, GuardDex flashes it back masked and coaches them on the spot. We never store the password. Find out who's at risk before a real scammer does.
When a risky login page is caught, the challenge screen asks them to type the real official address — training them to spot fakes, not just blocking silently.
A safe sandbox to practice and learn — see how scams and attacks actually work, with zero risk to real accounts or devices.
A 94-test security suite that continuously verifies GuardDex itself is doing its job — every detector, checked.
Open a suspicious link in an isolated, Tor-routed browser — capture its screenshot, redirect chain, and SSL details without it ever touching your device.
The web side a trusted family member uses to watch over everyone.
