About A Security
A Security (also styled Ⓐ) is an autonomous offensive cybersecurity and remediation platform that discovers, validates, and remediates exploitable attack paths before weaponized AI can use them. Founded in 2025 by Yossi Torati (CEO), Omer Gull (CPO), and Yuval Itzchakov (CTO)—alumni of Sygnia, Hunters, and Unit 8200—the company is headquartered in New York with founding roots in Tel Aviv. Its agentic platform continuously pressure-tests systems the way real adversaries do, chaining discoveries into proven kill-chains and closing the loop with automated remediation and retesting. A Security emerged from stealth after raising about $37M across a Cyberstarts-led seed and a Lightspeed-led Series A, with angels including Wiz CEO Assaf Rappaport and Cyera CEO Yotam Segev. Keywords: autonomous penetration testing, offensive security, AI security agents, attack path management, continuous security validation, remediation, Cyberstarts, Lightspeed, Yossi Torati, Omer Gull, Yuval Itzchakov
