Astelia Secures $35M Series A
Astelia, an Israel-based AI-native exposure management platform, has raised $35M in Series A funding led by Index Ventures, with participation from Team8 and Holly Ventures. The company maps network topology using agentic AI to pinpoint the ~2% of vulnerabilities that are truly reachable and exploitable, providing evidence-based remediation guidance. The capital will fuel platform expansion and go-to-market efforts amid surging cybersecurity threats.
AI Reachability Redefines Vulnerability Prioritization
The timing aligns with intensifying focus on AI-driven cybersecurity, as exposure management platforms gain traction. Astelia's launch with $35M underscores investor confidence in precision over probability-based risk assessment, differentiating from traditional tools reliant on CVSS scores.
Vulnerability Noise Buries Real Threats
Security teams face overwhelming vulnerability backlogs in complex enterprise networks, with Fortune 50 and 100 companies among those struggling. Traditional scoring systems flag thousands of CVEs, yet only ~2% prove reachable due to network topology constraints. Current solutions fail by prioritizing probabilistically, leading to inefficient patching and persistent exposure.
Agentic AI Maps Attack Paths Precisely
Astelia's platform conducts reachability analysis, visualizing attack paths and delivering tailored remediation beyond mere patching. Unlike competitors using static scoring, it leverages agentic AI for dynamic, evidence-backed insights into exploit requirements.
As Astelia's founders, ex-leaders of Israel's national red team, explain in their origin story:
"Why we founded Astelia: A Red Team’s perspective on fixing what’s broken in cybersecurity."
This offensive-defensive expertise enables visibility gap analysis and SOC2/ISO-compliant deployment.
Index Ventures Validates Red Team Expertise
Index Ventures leads the round, joined by Team8—known for backing Israeli cyber unicorns—and Holly Ventures. This investor mix signals strategic validation for Astelia's pivot from red team guesswork to AI precision, positioning it for growth capital in a threat-evolving landscape. The funding connects directly to scaling for Fortune-level clients like energy and finance giants.
Exposure Management Funding Heats Up
The exposure management sector attracts heavy investment as AI addresses dynamic threats. Astelia joins a wave where platforms target enterprise-scale networks, with its customers including AlphaSense, Syniverse, UCT, Bilfinger, Atera, and Wepa demonstrating early traction. Available on AWS Marketplace, it taps into cloud security demands.
Israeli Red Team Founders Drive Innovation
Founded by former leaders of Israel's elite national red team, Astelia brings battle-tested offensive and defensive cybersecurity know-how. This unique pedigree—rare in the space—credibly challenges legacy vulnerability management, with the team delivering compliant solutions for complex environments despite 11-50 employees.
