Penetration Testing Online Games

Security expertise for any game.

Secure your game

Our penetration testing and cybersecurity services are aimed at creating a safer online environment for your game. Neglecting strong, thoroughly tested, and dependable security measures can leave developers vulnerable to malicious attacks. These vulnerabilities include in-game cheating through game modifications and packet tampering, which may snowball into revenue and customer loss.

With over 20 years of experience in gaming security, our team know exactly what to look for when it comes to testing and pushing the boundaries of your systems’ security.

We bring the mentality of a player and we offer our services to a wide range of genres including FPS, MMOs, and RPGs. As gaming specialists, we have seen and heard it all when it comes to how games can (and will) be attacked in the digital space.

We build our methods and testing packages around the things we learn as both player and security specialist.

Building blocks for testing

We believe in the creative power of collaboration. Our teams are at their best when they work in pairs. Our unique pair hacking approach allows us to not only cut testing time for your game in half but to create peer-reviewed and validated quality assurance loops that yield far more in-depth and creative results.

Our in-depth penetration testing will tackle your game security across the board. When it comes to testing, we approach it as both a player and an ethical hacker. We have a deep understanding of several game engines and the typical injection points for malicious actors. Thanks to the combination of our professional and personal experience with gaming, we typically find more than 25 bugs in a test cycle for a pre-release game.


Passive Phase Reconnaissance

This is where we get to know your game. our teams determine the scope of your project by examining the target system, its architecture, programming languages, and functionalities.

Active Phase Target Penetration

Here, we do a deep dive with a full, manual penetration test of your game based on our reconnaissance and previous findings. Often, this process can account for up to 80% of the entire penetration testing cycle!

Reporting Debrief & Next Steps

Once the full testing cycle has been completed, we deliver extensive, detailed reports. This covers all system vulnerabilities that we discovered, from small insertion points to major security issues. With this, we can provide the best practice solutions that work with your workflows and processes. We also outline fully the potential risks of each issue and how a malicious agent could exploit them.

Frequently asked questions

A penetration test, or pentest, is an authorized simulated cyberattack on a system or application. It is conducted by our security engineers to evaluate the security present. It is used to test and validate the security maturity of your systems by uncovering, exploiting, and resolving cyber and IT related vulnerabilities.
The cost is based on the functionalities present and you are only charged for what needs to be tested. Get in touch with us to learn more about a testing quote.
