Cyberattacks focus mainly on the financial, government, military and infrastructure sectors — with finance leading at around 1,100 attacks per week. Ransom demands have also risen sharply in recent years, reaching between 4 and 14 million USD. Don't become their next victim! I'll identify and help you fix vulnerabilities in your software, such as:
Continuous learning keeps me up to date with the latest attack scenarios.

I take part in many industry conferences as both speaker and attendee — including as a speaker at The Hack Summit (2021 and 2023).
I keep upskilling constantly — I have completed 70+ industry trainings and courses, and run some myself. Cybersecurity changes every day, so staying current is essential.
We talk about your needs, goals and scope — no obligation.
I define the exact scope, timeline and a quote matched to the risk.
I run the tests, combining manual techniques with custom tooling.
A clear report: vulnerabilities, real risk and concrete remediation steps.
After fixes are applied I verify the vulnerabilities are effectively closed.
I price every project individually — I don't publish rates because I match them to scope and risk.
I started my security career in the Data Center of one of the largest banks in Poland, where I soon became a penetration tester. Later I delivered audits for, among others, one of the world's largest investment funds, software houses, and the automotive and hospitality industries. Today I lead an offensive security team at a global technology company — running penetration tests, Red Team exercises and cloud security assessments. I discovered the public vulnerabilities CVE-2018-8763 and CVE-2018-8764, and I speak at industry conferences.
In 2018 I founded CYBERSEC, under which I help organizations improve their cybersecurity. That same year I started my blog my127001.pl to share knowledge. For the past few years I have also been developing a specialization in the security of solutions based on artificial intelligence and large language models (AI/LLM).
