Tapkey is Pentest Approved by SySS GmbH

Tapkey Security approved by SySS

Security is a top priority at Tapkey, and we continuously strive to ensure our systems meet the highest standards. To uphold this commitment, we don’t just rely on internal checks—we regularly commission independent penetration tests to challenge our systems from the outside and uncover potential vulnerabilities before they can be exploited. To be more specific, we’ve commissioned SySS GmbH, the market leader for penetration tests in Germany and Europe, to perform a penetration test on our systems.

What is a penetration test?

It’s a security analysis in which “white hat hackers” try to break into the system to uncover security holes and vulnerabilities before someone else finds them and uses them to their own advantage.

2025: Focused on Communication Between App and Locks

While Tapkey has undergone penetration tests in the past, we’d like to highlight the latest assessment conducted by SySS GmbH in 2025. This time, the focus was on a critical part of our system: the communication between the Tapkey App and DOM/Tapkey locks.

To ensure SySS had everything they needed to uncover potential vulnerabilities, we provided full access—including source code, technical documentation, a detailed introduction to our communication protocols, and a complete set of test devices. With these tools in hand, the ethical hackers launched a series of simulated attacks—putting our system to the test from every angle.

As in previous assessments, SySS operated independently, simulating real-world attack scenarios to evaluate the robustness of our solution. The outcome confirmed what we had expected: a strong, above-average security posture.

Strong Results Confirmed

We’re pleased to share the outcome of the latest test:

“The overall security level is rated as good and above average.” – Quote from the SySS final report.

Even though the experts from SySS had a clear advantage over potential black-hat hackers, no major vulnerabilities were found—further validating the strength of our solution and confirming what our internal assessments had already suggested. Security is never a one-time achievement. We’re continuously raising the bar to deliver the same strong results in future tests. We evaluate and refine our setup to uphold and improve the high security standards our users rely on. At Tapkey, security is not an afterthought—it’s part of our DNA.
