Astelia

Astelia is an AI-native exposure management platform that helps enterprise security teams identify and remediate the small fraction of vulnerabilities that are truly reachable and exploitable in their environments. Founded in late 2024 by three former commanders of the Israeli national red team — CEO Alon Noy, CTO Nadav Ostrovsky, and CPO Roy Rajwan — the company was incubated through Team8's Venture Creation model. Astelia maps network topology using read-only integrations with infrastructure and network tools, then applies proprietary agentic AI to analyze the technical requirements for exploitation of each vulnerability. The platform surfaces the 1% of vulnerabilities that pose true risk, delivering actionable remediation guidance beyond patching to include network-based and compensating controls. Astelia launched publicly in February 2026 and raised a $10 million Seed round followed by a $25 million Series A.
