## Notes

(https://cognition.com/blog/corridor-joining-cognition)
- Jack Cable announced Galligan joining Corridor as Security Engineer on 2026-05-20, writing verbatim: "Matt and I first worked together at CISA, where he was the only person to beat me in the President's Cup hacking competitions" and "Most of his career has been on the offensive side from months-long red team engagements, vulnerability research and pentesting government systems." (https://www.linkedin.com/posts/jackcable_very-excited-to-share-that-matthew-galligan-activity-7462893423906422784-vPPi)

- Corridor launched 'Security Enforcement for long-running agents' for teams running Devin, Claude Code, Codex and Cursor on 2026-09-30, a month before the Cognition deal; Galligan reposted it.

- Posted on LinkedIn about the DEF CON 34 work, verbatim: "For DEFCON 34 Jack Cable and I spent some time examining weaknesses in Agentic code triage, and what we found was pretty interesting." and "No \"Advanced Nation-State\" level threats, no complex obfuscation, just good old social engineering!" (https://www.linkedin.com/posts/activity-7497671464880541696-ofV6)
- Pitched Corridor publicly on 2026-06-05, verbatim: "In 2026 if you are a pen-tester or security engineer, you probably have 4X the code to cover since last year, and if you are lucky your security team didn't get cut in half." (https://www.linkedin.com/posts/activity-7468500751909146624-k4F7)
