Who We Are
Built by security engineers who got tired of tools that cry wolf.
Pennrows exists because the status quo in enterprise security is broken. We built it to fix it.
Origin
Years building and breaking enterprise systems. One shared frustration.
Our founders spent years on both sides of the fence: securing critical infrastructure and probing it for weaknesses. They saw SAST tools generate thousands of false positives that teams learned to ignore. They watched email filters miss sophisticated BEC attacks that a human would spot in seconds.
Pattern matching had hit its ceiling. Reasoning AI had not. We built Pennrows to apply Claude where static rules fail: tracing logic in code, evaluating context in emails, and separating genuine threats from noise.
Mission
To make enterprise security intelligent enough that teams can focus on building, not triaging.
We believe security tools should reduce cognitive load, not add to it. When every finding is verified and every alert is actionable, your team spends time shipping, not sifting.
Values
How we work.
Rigour Over Speed
We ship when it's right, not when it's fast. Every finding is verified before it reaches your team. No triage theatre.
Signal Over Noise
SAST tools generate thousands of false positives. We built Pennrows to reason like a senior engineer and surface only what matters.
Transparency By Default
Our models, our methodology, and our limitations are documented. You deserve to know how your security decisions are made.
Engineering First
We are builders. Our product roadmap is driven by what engineers need, not by what enterprise sales cycles demand.
