Cybersecurity platform Astelia announced it has raised $35 million in funding to use artificial intelligence to expose real risks to organizations.
Company officials said Astelia uses a deep analysis of clients’ real environments via AI to map its network topology, segmentation and security controls, while using other AI agents to exploit system vulnerabilities. By using AI, the company said it is able to narrow down areas of risk down to those that are genuinely exploitable, so the company can deliver environment-specific remediation plans to reduce a company’s exposure without forcing unnecessary patches in production systems, saving security and IT teams significant time and remediation costs.
“When you’ve spent years on both the offensive and defensive sides, you learn pretty quickly that most of the vulnerabilities defenders worry about are irrelevant to how attacks actually work,” said Alon Noy, CEO and Co-Founder of Astelia. “We built Astelia because seeing that gap from both sides made it clear the industry was optimizing for the wrong problem. Security teams need to see their environment the way an attacker does, not the way a scanner does.”
Noy previously served as the leader of Israel’s National Red Team, the unit responsible for stress-testing the country’s critical infrastructure defenses. Noy has also worked with the US Cyber Command. Co-founders Nadav Ostrovsky (CTO) and Roy Rajwan (CPO) also served in key roles in the Israeli intelligence community as well as Israel’s National Red Team, where they led elite teams focused on real-world attack paths, adversary behavior, and large-scale defensive systems.
The company said the funding comes from seed and Series A funding led by Index Ventures and Team8 with participation from Holly ventures. The company already has dozens of customers, including those on the Fortune 500 list.
“As AI reshapes both attacker capabilities and defensive expectations, the strategic imperative for enterprises is to move from assumed risk to provable exposure,” Juriaan Duizendstraal, Partner at Index Ventures, said. “Solutions that show where organizations are actually exposed enable CISOs to align cybersecurity with business priorities, reduce wasted effort, and turn vulnerability management from a reactive scramble into a preemptive defense.”
