Astelia is a cybersecurity company focused on exposure security, founded by veterans of the Israeli national red team with backgrounds in both offensive and defensive security. The company's platform is designed to provide organizations with proof-based visibility into their actual security exposures, moving beyond traditional vulnerability management approaches. Astelia's core offering centers on exposure management — identifying where organizations are genuinely exposed to attack rather than relying on assumed or theoretical risk. The platform is built to cut through vulnerability noise, helping security teams prioritize and operationalize security efforts based on real-world attack paths and proven exposure rather than broad vulnerability lists. The product is informed by the founders' experience testing real-world defenses in complex environments, embedding an attacker's perspective into how exposures are identified and surfaced. This approach is intended to help CISOs align security investments with business priorities and shift vulnerability management from a reactive posture to a more preemptive one. Astelia's target market is enterprise organizations. The company is backed by investors including Index Ventures, Team8, and Holly Ventures. Leadership includes Co-Founder & CEO Alon Noy (Neuhaus), Co-Founder & CTO Nadav Ostrovsky, and Co-Founder & CPO Roy Rajwan.
