GuardDex · Family cybersecurity

Protect the people you love from scams and phishing.

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.

What is GuardDex?

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.

What it does

Layered protection that covers the whole phone — not just one browser.

🛡️

DNS Shield

Blocks known phishing and malware sites across every app — texts, email, browsers, social media — not just one. Runs quietly in the background.

🎣

Phishing & scam detection

Checks links and websites against a 44-brand impersonation database plus live AI analysis, catching fake bank, delivery, and "tech support" pages.

💬

Scam-message alerts

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.

🌐

Safe browser

A built-in browser that scans pages as you go, blocks ads and trackers, upgrades to HTTPS, and strips fingerprinting.

🔔

Pre-click warnings

Watches notifications from all apps and flashes a warning before a dangerous link is ever tapped.

🧑‍🤝‍🧑

Guardian alerts

A trusted family member can be quietly notified when something risky happens — so no one faces a scam alone.

How it works

Set it up once. It protects in the background from then on.

Install & turn on the Shield

A short guided setup turns on DNS Shield and notification protection. No technical knowledge needed.

Every connection is checked

As the phone reaches out to websites, GuardDex checks each destination against its threat lists — and silently blocks the bad ones.

Risky links & messages get flagged

Suspicious URLs and texts are analyzed by AI and matched to known scam patterns, then explained in plain English.

A clear warning appears

Instead of a confusing error, the person sees a calm, readable warning telling them what's wrong and what to do.

A guardian can be looped in

If set up, a trusted family member gets a gentle heads-up — or the person can tap "Ask my Guardian" for help.

Why use GuardDex

Most security apps are built for IT departments. This one is built for your family.

Made for older adults

Scammers target seniors hardest. GuardDex is designed to protect them without overwhelming them.

Plain language, not jargon

Warnings say what's happening in words anyone can understand — no error codes, no panic.

Privacy-first & self-hosted

Your data isn't sold or mined. GuardDex runs on Richey Business servers, not Big Tech's.

Family peace of mind

The guardian feature means you can quietly help a loved one stay safe, from anywhere.

Whole-phone protection

DNS Shield covers every app at once — not just a single browser you have to remember to use.

Real people behind it

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

Extra features

Going further than a typical security app.

🔒

Private VPN

An optional full-tunnel WireGuard VPN routes traffic through a private exit for extra privacy on public Wi-Fi.

📡

Ultrasonic tracker detection

Detects inaudible "ultrasonic beacons" some apps and ads use to track you across devices.

🔓

Breach monitoring

Checks whether household members' emails have shown up in known data breaches, and watches for new ones.

🕵️

Data-broker exposure

Shows where your personal information may be listed by data brokers so you can request removal.

🧩

Browser extension

The same link-scanning and ad/tracker blocking for Chrome & Firefox on the desktop.

📰

Scam Watch updates

Plain-language alerts about the scams making the rounds, so your family knows what to watch for.

Red-team & phishing tests — built in

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.

🎯

Attack Studio

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.

🎣

Practice scam drills

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.

🛡️

Anti-phishing training

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.

🧪

Attack Lab

A safe sandbox to practice and learn — see how scams and attacks actually work, with zero risk to real accounts or devices.

TestBench

A 94-test security suite that continuously verifies GuardDex itself is doing its job — every detector, checked.

🔬

URL Sandbox

Open a suspicious link in an isolated, Tor-routed browser — capture its screenshot, redirect chain, and SSL details without it ever touching your device.
