Was your security stack built for this moment? Probably not. When frontier models emerged and adversaries weaponized them before defenders could react the glass shattered. Malicious agents are crawling environments at all times today, not only finding the high-severity vulnerabilities but chaining vulns of all kinds into real-world attack paths and automating exploitation. This represents a new reality that the old security model was not built for. We don’t just need a new approach. We believe we need a new foundational technology.
Enter A, our investment in a platform that we believe can beat weaponized AI at its own game.
You can’t retrofit this moment. Legacy approaches – pentests and posture assessments for example – are often limited because they either primarily identify areas of theoretical risk, or because they cannot scale. But the days of theoretical risk are over. Today malicious agents can turn a risk hot-spot into a real-world attack almost instantly. That pentest is out of date the moment it ships. Defenders today need a platform that can outpace weaponized AI, finding, demonstrating, validating, and remediating exploit paths before a malicious agent can actually exploit them.
Defenders today are experiencing much more than an incremental shift. The proliferation of AI has armed even unsophisticated attackers with nation-state level capabilities. The ability to identify, chain, and script exploit paths represents a speed and scale of incoming attacks that defenders are ill-equipped to deal with. This breaks the old security model.
This is why we’re excited to announce our investment in A Security as the company emerges from stealth.
A Platform Built for the Mythos Era
A Security is the platform for the modern defender. Their approach – utilizing offensive and defensive agents to continuously discover, validate, and eliminate real-world exploit paths before attackers can use them – will soon be an industry requirement in our opinion. By focusing on validated exploitability rather than theoretical risk, and demonstrating exactly how an AI-powered attacker could infiltrate and exploit an environment, the platform helps organizations to fortify themselves against the attacks that AI-enabled adversaries are launching en masse today.
A continuously stress-tests applications, identities, and infrastructure at scale. It identifies how isolated weaknesses can be chained into attack paths, providing a real-time, safe picture of validated risk.For overwhelmed security teams in industries where even a moment of failure is not an option, A helps provide clarity by pinpointing the paths that lead to disruption. This transforms security from a periodic exercise into an always-on system for understanding and reducing real risk.
The Team and the Customer Need
The A founding team has been in the eye of this storm for decades, and they saw first hand how the game changed once adversaries started deploying weaponized frontier models. A pentest or table-top exercise was once a legitimate method for reducing risk. But once malicious agents collapsed the mean-time-to exploit from days to minutes the A founders recognized the need for a new foundational technology.
Yossi Torati, A’s CEO and Co-founder, has been in the trenches helping global enterprises combat sophisticated cyberattacks for nearly two-decades. As Director of Enterprise Security at Sygnia, Yossi regularly engaged top-tier advanced persistent threat groups and coordinated global incident response programs. Omer Gull and Yuval Itzchakov, A’s Co-founders bring similar deep experience from Check Point Software, Hunters, and Unit 8200, combining expertise across red teaming, vulnerability research, AI, and cybersecurity engineering.
This background means A is building from first-hand knowledge of how attackers operate, how enterprise environments break, and where existing security workflows often fall short.
A is already working with large organizations across finance, healthcare, critical infrastructure, and technology, where security teams are under pressure to validate and close real attack paths faster than manual testing cycles allow.
Why We Invested
Today’s cyber defenders need a weapon that can beat weaponized AI to the punch. We believe A Security is that platform.
We invested in A Security for three core reasons that we believe set them apart:
- Front-Line Experience: The team’s unmatched experience comes from years of being “in the trenches” of enterprise security and incident response, ensuring they are building from first-hand knowledge of attacker operations and where existing security workflows typically fail.
- Validated and Closed-Loop Vision: A Security’s expansive vision goes beyond finding theoretical issues. Their platform focuses on validated exploitability and closes the loop by providing continuous remediation guidance to eliminate real-world exploit paths before attackers can use them.
- Incredible Customer Validation: Early adopters in enterprise–including large organizations in finance, healthcare, and critical infrastructure–have provided incredible feedback, validating the need for an always-on system that can identify and close attack paths faster than manual testing cycles.
A Security is fighting weaponized AI with AI, which is exactly what this moment requires. We are proud to partner with Yossi, Omer, Yuval, and the entire A team as they work to tilt the balance of power back toward defenders.
