Astelia

Based in New York City, Astelia develops an AI-native exposure management platform that maps network topologies to identify exploitable vulnerabilities across on-premises, hybrid, and cloud environments. The software utilizes agentic artificial intelligence to isolate the approximately two percent of vulnerabilities posing actual threats based on real-world attack paths. Available through the AWS Marketplace, the platform provides security teams with evidence-based remediation guidance, including alternative mitigations like firewall rule adjustments. The company serves dozens of enterprise clients, including Fortune 500 corporations, and can narrow down nearly three million potential vulnerabilities to roughly thirty actionable exploits. Astelia has secured $35 million in combined seed and Series A funding from lead investors Index Ventures and Team8, alongside Holly Ventures. The organization was founded by former leaders of Israel's National Red Team, including Alon Noy, Nadav Ostrovsky, and Roy Rajwan.
