Protecting What They're After
We know their playbook — and we built SIMGUARD to spot the early moves.
Who We Are
SIMGUARD is a mobile security company built for one job: help you see identity and account threats on your phone before the damage spreads.
Not another generic antivirus app. Not a scare screen that nags you for no reason.
SIMGUARD watches the signals attackers actually use — SIM and carrier changes, suspicious login patterns, spyware and stalkerware, fake apps, risky 2FA conditions, scam links, and wallet lookalikes — and turns them into clear alerts you can act on.
Your phone is the key to your number, your email, your bank, your social accounts, and your money. SIMGUARD is built to protect that whole chain.
Why We Built It
SIMGUARD didn't start in a boardroom. It started with a real problem.
Our founder went through these scams firsthand — the pressure calls, the fake urgency, the links that looked official, the losses that hit before there was time to think clearly. After that, the question wasn't "how do I feel safer?" It was "why isn't there something on my phone that actually warns me earlier?"
That's why SIMGUARD exists.
Most people only find out they've been hit after the money is gone, the number is ported, or the account is already inside. Banks, exchanges, and carriers often warn too late — when the attacker is already through the door.
We built SIMGUARD because the gap isn't more passwords. It's early visibility.
The first move in a SIM swap.
The cluster of OTPs that doesn't add up.
The hidden app that shouldn't be there.
The link that looks official but isn't.
Those are the moments that matter. SIMGUARD is designed to catch them while you still have time to freeze, verify, or call the right place — so fewer people have to learn the hard way.
Built on Real Research — Not Guesswork
SIMGUARD's detection logic is shaped by how modern attacks are actually documented — not blog hype. Our correlation engine draws on publicly available threat research and security frameworks, including work from:
MITRE ATT&CK (mobile threat patterns)
CISA (identity and mobile security guidance)
ENISA (EU cybersecurity standards)
OWASP Mobile Application Security
EFF (digital rights and surveillance research)
Amnesty International (spyware forensics)
FBI IC3 (internet crime reporting patterns)
Coalition Against Stalkerware
SEAL and industry drainer-intel research
GSMA telecom-security guidance
These sources inform how SIMGUARD connects weak signals into meaningful warnings — SIM changes near auth bursts, hostile-network shapes, spyware-like app behavior, wallet-risk patterns, and scam playbooks seen in the wild.
We don't claim endorsement from any lab or agency. We study their public research, map it to real phone behavior, and build detection that fits how attacks actually unfold on Android. That's the difference between a security app that sounds serious and one that is serious.
What We Believe
Your phone should work for you, not against you.
If someone can own your number or your device, they can own a lot more.
Early beats late.
Detection and warning matter more than a polished apology after the fact.
Privacy is part of security.
Core monitoring runs on your device. SIMGUARD does not need your account passwords. We do not sell your data. We do not build an ad profile from your alerts.
Real tools should be usable before you pay.
Spyware Check, Verify a Link, Scam Watch, Defender Drill, Security Briefings, and SCAM SHIELD are free because trust starts with something you can actually try.
Honest security beats fake promises.
SIMGUARD provides detection, guidance, and logging — not a guarantee that every attack can be stopped. We tell you what we see. You stay in control of what you do next.
How SIMGUARD Works
SIMGUARD uses multiple on-device detection layers working together — not one blind spot pretending to be full protection.
Detect
SIM status, authentication patterns, installed apps, links, and wallet-related signals.
Correlate
Connect weak signals into a pattern that looks like a real attack.
Alert
Send a clear heads-up when something looks off, with a path to the next step.
That's the difference between noise and a warning worth your attention.
