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.
IT Technician, B.Eng. in Information Processing & Protection, M.Sc. in Data Security in Computer Systems
Key certifications: CISSP, OSWE, OSCP, Burp Suite Certified Practitioner, eWPTX, eWPT, AWS Certified Cloud Practitioner. See all →
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.
Compliance is today the most common reason companies order security testing. I run penetration tests that meet the requirements of key regulations and standards — with an audit-ready report.
Testing and assessment of security effectiveness required from essential and important entities.
Digital operational resilience testing required from financial entities (since 2025).
Regular penetration testing required when handling payment card data.
Testing that supports certification and maintenance of your information security system.
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).
