Security review, multi-tenant SaaS

Remote code paths closed before the next release.

The best incident is the one that never happens.

We design for failure from day one, so your team sleeps through the night.

Six tools. Each one started as a fix for a real problem.

  • Lynx Replay

    Reproduces a support case on web and Android and attaches the evidence.

  • Lynx Parity

    Proves a rebuilt system gives the same output as the old one.

  • Lynx Shield

    Finds and closes injection paths across every release branch.

  • Lynx Triage

    Routes each ticket to the person who can close it, with context.

  • Lynx Proof

    Keeps the source and timestamp behind every fact a report states.

  • Lynx Vision

    Reads plans, forms and photos from the field into structured data.

Built to reach production.

  1. Diagnose

    We map the system, the data and the real constraint before anyone writes code.

    System map

  2. Prototype

    A working slice against real inputs, measured with evaluations agreed up front.

    Eval suite

  3. Harden

    Security review, load tests, observability and failure drills before launch.

    Launch checklist

  4. Operate

    We run it with your team, or hand it over with runbooks and the know-how.
