We get in first.

Yegg is an offensive security firm built for the machine-speed era. The name is old slang for a safecracker — someone who opens what was meant to stay shut.

01 — Mission

Continuous offense, on your side.

Attackers stopped working on an annual schedule a long time ago. Yegg pairs autonomous AI agents with career operators to find exploitable paths into your systems — not once a year, but continuously, and always on your side.

Every engagement ends the same way: with demonstrated attack paths, working proof, and fixes that hold. No scanner output repackaged as analysis, no severity ratings invented to fill a report.

02 — What we believe

Proof over prediction

A finding that can't be demonstrated isn't a finding. Everything we report is exploited end-to-end and reproduced before it reaches you.

Machines for breadth

Agents map, probe and chain at machine speed across your whole surface. Breadth is a solved problem — so we solve it.

Humans for depth

Business logic, chained context, judgment calls. Senior operators steer the swarm and sign every report that leaves the building.

03 — Timeline
2025

Founded by operators

Career red-teamers and agent engineers who kept watching annual pentests miss what a weekend intruder would find.

2026 Q1

First swarm, first proofs

Early engagements demonstrated tenant-wide paths in hours, not weeks — the model worked.

2026 Q3

Continuous engagements

Moved from bounded tests to standing coverage — the swarm watches your surface as it changes.

NOW

Building in the open

Field notes, published tradecraft, and a disclosure program — because we should practice what we test.

Facts
founded — operators + agent engineers
people, remote-first US + EU
agents in the standing swarm

04 — The firm

Small on purpose.

We're a compact team of operators and agent engineers, remote-first across US and EU timezones. We hire for tradecraft and judgment over headcount — the swarm does the scaling.
