A hacker doesn't need your servers. Just your app.

Your app sits on millions of phones, and anyone can pull it apart to find hardcoded keys, hidden logic, and a way in. We take your app apart the same way, on Android and iOS, before an attacker does.

The question that matters

Your app looks secure. But has anyone tested where the flaws and gaps are?
WHY MOST MOBILE TESTINGs FALL SHORT

A quick scan never opens the app up

Most mobile vendors run an automated scanner and stop. Real attackers download the app, decompile it, and read the code for keys and flaws. If no one takes your app apart, that whole risk is untested.
Most Mobile App Security Vendors
Automated scanning, barely any manual testing
Tests the app, leaves the APIs out of scope
Reads the code, never runs the attack
A pile of findings with no priorities

Process

How it works

Simple, step by step, from opening the app to confirming the fix.

Understand the app

You tell us what the app does and what matters most. We plan the test around it.
01

Take the app apart

We decompile the app and read its code to see how it really works.
02

Go after the backend

We test the APIs and servers the app talks to, where the real data lives.
04

Run it and attack it

We run the app on rooted and jailbroken phones, bypass its protections, and watch what it does.
03

Explain what we found

Every issue in plain language, ranked by how much it would hurt the business.
05

Fix and re-check

We help your team fix each issue, then test again to be sure it's closed.
