We build the tools we wish<br>existed when nobody was looking.<br>In July 2024, a single kernel-driver update bricked 8.5 million machines[1] in a morning. The fix was a manual safe-mode visit per machine. The product was the biggest name in endpoint security.<br>That's the failure mode we're built against. Not the threat. The tool we use against the threat. An EDR you can't turn off and can't silently crash. A pentest tool that scoreboard-verifies what it claims.<br>Written in Rust, signed end to end. No “AI-powered” copy where it doesn't belong.
The product line.<br>Each one solves a real problem and ships under its own brand. Don't need both? Don't buy both.
Nemesis Blue· endpoint defense<br>An EDR that catches ransomware in under a second, and can't brick your fleet on a bad update.<br>The big-name kernel drivers BSOD-looped 8.5 million machines last year[1]. Blue runs on EndpointSecurity (macOS) and eBPF (Linux). Kernel-authorized APIs that can't panic the kernel. Behavioral detection on a kernel-sourced event stream, not signature matching.<br>download →trust center →

One stack. Two coordinates.<br>Each product is shippable on its own. Together they cover both sides of an engagement. Finding the holes, then stopping what comes through them. A customer never has to glue separate vendors together to answer one question.

Why Blue, when Falcon exists?<br>The honest answer: because Blue is architected for five constraints the big-name EDRs took shortcuts on. Each row below is a concrete capability, not a marketing claim. Every ✓ on the Blue column is something we'd defend in a technical interview.
