We Build the Tools We Would Want to Use
Reacts is a cybersecurity firm that delivers structured penetration testing engagements and builds the platform that powers them. PENTRA was developed because we could not find a tool that produced measurable, evidence-backed results at the technique level — so we built one.
Our mission is to make security testing measurable, not just performative.
The security industry has a problem: most penetration tests produce a PDF report, a risk rating, and a recommendation list. What they don't produce is a validated, evidence-backed picture of exactly which techniques succeeded, which were detected, and whether scope was fully covered.
Reacts built PENTRA to solve this problem. Every engagement we deliver — and every engagement our customers run — produces structured data: a Security Score, a Detection Rate, proof of execution for every technique, and a compliance-ready audit trail.
PENTRA is the operational core of every Reacts engagement — and it is available to security teams and consulting firms that demand the same standard for their own operations.
Our Principles
The commitments that govern how we build and how we operate.
We do not sell outcomes we cannot measure. Every claim our platform makes — Security Score, Detection Rate, Scope Coverage — is backed by validated, engineer-confirmed data.
Good security testing requires structure. PENTRA enforces methodology through its execution model — techniques are selected, executed, validated, and evidenced in a repeatable, auditable process.
Our clients see exactly what was tested, what the outcome was, and what evidence supports each finding. There are no estimates, assumptions, or black-box outputs.
PENTRA is deployed on-premises. Your engagement data never leaves your infrastructure. No cloud connectivity required. Your security posture is yours alone.
Security professionals who run the engagements they build for.
The Reacts team is made up of certified security engineers, offensive security researchers, and compliance specialists. The same team that delivers client engagements contributes to the PENTRA Security Lab — ensuring the platform's technique library reflects what practitioners actually encounter in the field.
