Quinn Defense Systems
Mastery, not menace.
In 1986, on a Texas Department of Transportation PC, a young engineer loaded a freeware utility called Professional Master Key — a tool that could undelete files and, as he discovered, wipe an entire operating system. A weekend and a patient clerk at a Dallas computer store later, everything was restored. It nearly cost him his job. It started a forty-year career.
We reclaimed the name on purpose. A master key that once nearly destroyed everything now hands the right person total, safe control over what is theirs.
The founder
JP Quinn spent forty years across five critical-infrastructure sectors: the Texas Department of Transportation, the Superconducting Super Collider, nuclear power, healthcare, and twenty-five years at AT&T as a software engineer, senior DBA and cybersecurity practitioner working insider-threat data.
Using computers since 1977 and Unix since 1985. InfraGard member for over fifteen years. He built Nexus Prism after retiring, alone, to a deliberate standard: production-complete before go-to-market, never a demo.
How we work
Provenance over assertion. We run our own nodes because a first-party observation survives cross-examination and a resold assertion does not.
Calibrate, don't claim. We built the instrument to measure our own error rates before it was ever a sales argument.
Say plainly what we don't do. Our security documentation contains an explicit list of claims we refuse to make, and it is published. The negative claims are as load-bearing as the positive ones.
Every failure becomes a written rule. Thirty-plus documented postmortems. A one-person company cannot afford to learn the same lesson twice.
Sell to people we would be proud to have as customers. Vetted access, screened buyers, enumerated authorised uses. The customer list is an asset.
What "one person" means, and does not
It means no sales organisation, no offices and no investors who need a return — which is most of why the pricing looks the way it does.
It also means a continuity question you are right to ask. There is a written continuity plan, source-code escrow is available at $2,500 per year, and on-premises deployments ship as signed images with licence-key entitlements that keep running regardless of what happens to us.
The work itself is the other answer. The platform has been built and documented in the open discipline of a public commit history: signed commits, conventional messages, and a written postmortem for every failure worth the name.
