About A Security

A Security, an Israeli company that uses the stylized name Ⓐ, runs continuous attacks against a customer's environment to find complete, exploitable attack paths rather than isolated vulnerabilities.

Its cycle has four stages: discover and validate paths that affect the business, build a prioritized attack plan that a human reviews and approves, execute the attacks as a chained kill chain with every step logged, and then document, fix and retest each finding.

Results feed into ITSM workflows so remediation is tracked to closure. The platform also checks whether existing defensive controls react as intended.

The company was founded by Yossi Torati, Yuval Itzchakov and Omer Gull, and angels include the chief executives of Wiz and Cyera.
