Founded by École 42 alumni with a passion for cybersecurity, PrismaSec was built on a simple belief: every growing company deserves strong security without enterprise complexity or enterprise budgets.
PrismaSec started at École 42, where our founders spent years solving difficult problems through peer learning, CTFs, and offensive security practice.
In the professional world, the gap was obvious: small and mid-sized companies face real cyber risk, but most security tools are too expensive, too complex, or both.
PrismaSec is our answer: a practical product designed to be easy to use, focused on clear results, and built for companies that need strong security without a dedicated security team.

Precision
Fewer false positives through human validation where it matters
A French CTEM platform and offensive experts for organizations that need to track verified public assets, reports, and fixes without unnecessary complexity.
Our 42 culture taught us to solve complex problems pragmatically. We do not flood you with raw vulnerabilities: we contextualize each finding, prioritize risk by real business impact, and connect evidence to reports, remediation plans, and retests.
Continuous validation for verified public domains, web apps, and APIs, combined with targeted human review for critical findings or expert scopes.
Three principles shape how we build cybersecurity products.
Trained through peer learning at one of the world's strongest computer science schools, we bring practical problem solving, continuous learning, and technical rigor to every customer engagement.
We think like attackers to help teams defend better. Our CTF and pentesting background helps us focus on real attack paths instead of checklist security.
Every product decision starts with a practical question: can a growing company use this without dedicated security expertise? The answer has to be fast onboarding and clear results.
Behind every result is a team of offensive security experts, trained at 42 and focused on making strong security accessible to your company.
