# A Security Raises $35M Series A Backed by Wiz CEO and Cyera CEO

> A Security has raised a $35 million Series A to build what it describes as an operating system for AI cybersecurity agents, and the backer list is the eye catching part. The round is supported by Wiz founder Assaf Rappaport and Cyera chief executive Yotam Segev, two of the most successful names in the recent wave of security startups, which lends the company immediate credibility in a crowded field. The premise is that as attackers begin using AI to move faster, defenders need autonomous agents that can detect, investigate, and respond at machine speed, and those agents need a common platform to run on. Rather than selling a single tool, A Security is pitching the underlying layer that many security agents could operate from. Security is one of the more plausible near term homes for agentic AI, because the work is repetitive, urgent, and already heavily instrumented with logs and alerts. The risk is that autonomous agents acting on live systems can cause damage if they get it wrong. Backing from founders who have built and sold major security companies suggests this is a bet worth watching.
