Threat Unknown was founded by security engineers from Amazon and Robinhood. We built and operated infrastructure protecting millions of users and billions in transactions. We know what serious security looks like.
We kept seeing the same pattern: startups and growing companies getting hit for the same preventable reasons. Not because they didn't care. The tools available were either too expensive, too complex, or too passive. Reports that nobody acted on. Alerts with no one to fix them.
So we built what we wished existed. An AI platform that does the ongoing work, continuously. Big-tech security practices, accessible to any team.

42% of Canadian organisations surveyed by CIRA reported a breach of customer or employee data in the last 12 months. 2025 CIRA Cybersecurity Survey, n=500.
We implement, configure, and ship. Every recommendation comes with working infrastructure behind it.
Details matter. From IAM policies to network segmentation, we get the specifics right the first time.
Security controls integrate with your existing stack. We design for how your teams actually work.
We think like attackers to build defenses that hold under real pressure.
Security that enables your engineering team, not a gate that blocks releases.
You see exactly what agents find, what they change, and why. No black boxes.
Two founders, one thesis. Real security outcomes come from people who have built and defended systems under pressure, not from another dashboard. Here's who's behind Threat Unknown.
