What is esChecker?

esChecker is a Mobile Application Security Testing (MAST) tool for mobile applications, running both Static (SAST) and Dynamic Tests (DAST), straight from the binary (blackbox).


It executes your applications on real mobile devices and launches attacks to detect failures in self-protection on .apk or .ipa files.


Thanks to having its device farm, it has unique capabilities to trigger attack techniques like reverse engineering or code tampering.


Let’s run an example scan:


1- First, you need to upload your application file (.apk/.ipa) 

esChecker upload your app

2- You can record a test sequence to guide the scanner to go through the most critical screens of your apps, allowing full code coverage.

3- Now, you can choose a scanning campaign depending on the type of your applications: Banking, gaming, healthcare or others.

These preset campaigns are provided in line with the OWASP recommendations.

4- and you will get the scan results in 20-30 min.

What makes esChecker unique?

esChecker is the only solution that executes your apps on a real device and runs attacks.


Most of the other mobile application security testing solutions use emulators to run the app and execute the attacks through it.


However, this methodology is limited when it comes to code coverage. Plus, if the apps are protected against the usage of emulators, the report would be biased.


Your apps will be running on a real device, and you will record your user journey and design your attack scenarios.


You can fine-tune your scans to recognise popups or error handling messages so your scan results will always reflect the right vulnerabilities. (no false-positive)

How is esChecker pricing works?

It is an annual subscription that you can buy for a number of applications. It is $10k per application approximately.


There is no limit on users or how many times you can scan your applications during the year.
