Mobile App Pentest
Do you have a mobile app and want to know how it's doing security-wise? At Tozetta we run a thorough mobile app pentest, from iOS to Android. Our ethical hackers hunt down vulnerabilities in the app itself, its API integrations and how data is stored.

[ 01 ]Vulnerabilities
Example mobile app vulnerabilities
The goal of running a pentest is to expose vulnerabilities before cybercriminals do. Click through examples of common vulnerabilities uncovered during mobile application pentests. We describe the risk level and impact, just as we do in our independent pentest report.
Insecure communication between app and server
Without certificate pinning or proper encryption, an attacker on the same network can intercept traffic between the app and server, also known as a man-in-the-middle attack, stealing sensitive data.
Certifications
Our ethical hackers are broadly certified
From OffSec to Hack The Box: the Tozetta team sets the bar high with internationally recognized, hands-on certifications. We put that in-depth expertise to work in every pentest, so organizations can count on thorough, high-quality security research.

[ 04 ]Pentest methods
Pentesting methods
Black, Grey or White box? Pick a method below and see instantly how much knowledge the ethical hacker gets up front, and therefore how realistic the attack is.
The hacker starts completely blind
Black box Pentest
In a black box penetration test the organization gives the ethical hacker no information about the systems and IT structure up front.
What the hacker sees up front

โI've capped off 5+ years of experience as an ethical hacker with an OSCP, OSED, OSWE, OSEP & OSCE3 certification. With that knowledge, I make sure your networks, websites, and mobile applications are tested thoroughly.โ





Frequently asked mobile pentest questions
How do I secure my mobile app against hackers?
To secure your mobile app against hackers, you can, for example, ensure strong authentication and authorization mechanisms, apply data encryption, implement security measures within the app itself, and regularly run a mobile app pentest.
What are the most common vulnerabilities in mobile apps?
The most common vulnerabilities in mobile applications include insecure data storage, weak authentication and authorization mechanisms, insecure communication and improper error handling. It's important to detect and fix these vulnerabilities to secure your mobile app.
How does a mobile app pentest work?
A mobile app pentest involves simulating an attack on the app to detect and fix vulnerabilities. This is done by an ethical hacker who uses various techniques to hack the app.
How often should I have a mobile app pentest carried out?
It's recommended to run a mobile app pentest annually or after major app updates, to detect and fix any new vulnerabilities.
How long does a mobile application pentest take?
The duration of a pentest depends on various factors, such as the type of test, the complexity of the system and the available budget. A pentest usually takes a few days to a few weeks, but it can also take months. The duration of the pentest is always discussed beforehand.
It's important to emphasize that the time an ethical hacker spends carrying out the pentest affects the thoroughness of the test and the methods applied. The more time the pentester gets, the better the test can be carried out.
Whether you need a one-day pentest or a more extensive pentest of several weeks or months, at Tozetta we always determine the duration of the test in consultation with the client. This way we can ensure the test aligns as closely as possible with your organization's wishes and needs.
