About us
A cybersecurity company built by penetration testers
DSecure.me Sp. z o.o. is a Polish security company based in Wrocław. We test web, mobile, API and LLM-powered systems the way an attacker would, then hand over findings your engineers can actually act on.
What we do
We were founded by consultants who spent years on both sides of the problem: building secure software inside financial institutions, and breaking it from the outside as pentesters. That shapes how we work. A report full of scanner output helps nobody, so every engagement ends with findings ranked by real business risk, reproduction steps a developer can follow, and a remediation plan with a retest included.
Our work covers seven services: penetration testing for web applications, mobile applications, APIs and LLM/AI systems, plus threat modelling, cybersecurity and IT consulting, and custom security solutions such as security architecture design, DevSecOps enablement and virtual CISO support. Engagements are delivered in English and Polish, for clients across Poland and the wider EU.
We run engagements against recognised public standards rather than a private checklist, so results are comparable and auditable: the OWASP Top 10 and Web Security Testing Guide for web, OWASP MASVS for mobile, the OWASP API Security Top 10 for APIs, the OWASP Top 10 for LLM Applications for AI systems, and STRIDE and PASTA for threat modelling.
