I help businesses close security gaps before they become a problem, and individuals regain control once something has already happened — audits, pentesting, expert witness reports and incident response, always backed by documented methodology.

They helped us structure the documentation and present the technical aspects in a much clearer, more professional way. It's clear there's real expertise in both cybersecurity and meeting the exact requirements requested.
Business · Public tender auditI had an account compromised by someone who gained access to it and didn't know how to react. From the start I received very clear guidance: what could have happened, what steps to take, and how to secure the account afterward so it wouldn't happen again. Attentive, professional support that helped me feel at ease again.
Individual · Account recoveryWe hired a vulnerability assessment to check whether our website had security issues we weren't detecting internally. The results uncovered several points that needed attention and helped us prioritize fixes, explaining the real impact of each issue rather than just handing over a list of problems.
Business · Web vulnerability assessmentI needed a technical report related to a security issue, well documented and suitable for formal use. The result was very professional, with information clearly organized and explained — and I really appreciated that the technical aspects were explained in an understandable way, not just in specialized jargon.
Individual · Formally valid technical reportWhen you have a security incident, you need someone to react fast and know what to do. The response was quick and professional from the very first moment: the situation was analyzed, possible causes identified, and we received clear guidance on how to contain the problem. I especially valued the sense of calm conveyed during a stressful situation.
Business · Security incident responseGreat experience with the penetration test. We needed to check how vulnerable our web application really was, and the analysis was extremely thorough — different attack vectors were reviewed and every finding was perfectly documented. Communication throughout the process was excellent, and the final report made it clear exactly what we needed to fix.
Business · Web application penetration testWe hired a cybersecurity audit because we wanted to know whether our systems actually had vulnerabilities. The analysis was far more thorough than expected and very well explained, with a clear report on the risks found and priorities for fixing them. I really liked the practical approach: not just finding flaws, but knowing what to do next.
