About Serenisec
Serenisec is a Dutch cybersecurity company that helps organisations protect their digital environment against external threats. We combine technical depth with a practical approach — so that security advice does not stop at reports, but actually leads to meaningful improvement.
We believe that good security starts with insight. That is why we focus not only on finding vulnerabilities, but also on understanding the context: how does your organisation work, what are the risks, and what are the most effective steps to reduce them?
What We Do
Serenisec offers a broad range of cybersecurity services, from one-off penetration tests to continuous monitoring:
- Penetration Testing — Web applications, networks, and APIs tested by experienced ethical hackers.
- Phishing Simulations — Insight into your employees’ resilience against social engineering attacks.
- Scanning & Monitoring — Continuous monitoring of your attack surface and vulnerabilities.
- OSINT — Open source intelligence to map your organisation’s digital footprint.
Our Approach
We always work on a custom basis. No generic report that ends up in a drawer, but clear and actionable advice tailored to your organisation and sector. After every assessment you receive a report that both technical staff and management can understand — with findings, risk ratings, and concrete recommendations.
Transparency and honesty are at the core of everything we do. We tell you what we find, even when that is uncomfortable.

- Personal approach — you always deal directly with the specialist doing the work
- Certified expert pentesters
