Pentrox Cybersecurity B.V.

Know which security risks need attention, what your team can do and whether fixes work. Pentrox is a boutique offensive security consultancy in Amsterdam, delivering senior-led pentests with clear priorities and practical follow-up.

Our ethical hackers bring complementary offensive security specialisms to each assessment. A second ethical hacker reviews every finding before publication. You work directly with your tester, with agreed objectives and scope.

Validated findings appear in the Pentrox Portal during testing. Critical risks are reported directly, so your team can start remediation while the assessment continues. Progress, evidence, questions, reports and retest status stay together in one workspace.

We test web applications, APIs, mobile apps, internal and external infrastructure, cloud environments, Azure and Entra ID, source code, hardware and AI/LLM applications. Red teaming, scenario-based tests, phishing simulations and physical security testing are also available.

Your technical report gives IT teams evidence and practical remediation guidance. The management summary explains risk and priorities for decision-makers. Retesting of remediated findings within 90 days of report delivery is included, helping your team verify fixes and document follow-up.

We deliver complete assessments as a team. Pentest as a Service supports recurring testing across releases or throughout the year. There is no fixed minimum project budget: scope and price are agreed for each engagement.
