Client Testimonials

Sophia C.

CISO, FinTech Startup

Nico's pentest uncovered vulnerabilities in our web infrastructure that we never had on our radar internally. The final report was clearly structured and immediately actionable, with concrete priorities instead of jargon for its own sake.

Ethan L.

Head of IT Security

The assessment showed us how far an attacker could actually get in our environment. Sobering, but exactly what we needed. Nico worked professionally and discreetly, and left us with a clear roadmap at the end.
