Code Security Reinvented Navigating the era of AI
summary
GitHub Security Lab reports 1,000+ security issues found, 700+ CVEs coordinated and a 96% fix rate, and shows four concrete AI uses: writing safer code with GitHub Copilot (GitHub says 60% of committed code was Copilot-generated), CodeQL for SAST that surfaces alerts and offers generate fix suggestions to create multi-file PR fixes, secret scanning and fuzzing string generation for testing, plus measurable adoption (MercadoLibre: 13,000 devs, 9,000 on Copilot, ~50% faster) and explicit limits — AI helps but does not replace testing or human oversight.
