Astelia Secures $35M in AI Cybersecurity Funding to Transform Vulnerability Management

Astelia, a pioneering New York-based cybersecurity startup, has raised $35 million in combined seed and Series A funding.

The investment round was led by Index Ventures and Team8, with participation from Holly Ventures.

Founders' Elite Background Fuels Breakthrough

Founded in 2024 by ex-leaders of Israel's National Red Team, including CEO Alon Noy, CTO Nadav Ostrovsky, and CPO Roy Rajwan, Astelia draws from real-world cyber operations expertise.

These veterans previously stress-tested critical infrastructure defenses and collaborated with US Cyber Command on advanced attack simulations.

AI-Powered Exposure Management Revolution

Astelia's platform leverages agentic AI to identify truly reachable and exploitable vulnerabilities, slashing noise from millions of alerts to just 2% high-risk issues.

By mapping precise network topology and correlating exploit requirements with actual attack paths, it delivers tailored remediation plans beyond mere patching.

This innovation addresses the exploding vulnerability landscape accelerated by AI, where exploits emerge on the same day as disclosures.

Market Impact and Competitive Edge

In a crowded field with players like Tenable and Rapid7, Astelia stands out through integrated network visibility and AI-driven prioritization.

The funding will double R&D capacity, enhance scanning features, expand engineering teams, and accelerate global sales growth.

Already serving Fortune 500 clients, Astelia aims to evolve into a comprehensive end-to-end exposure management solution.

CEO Alon Noy emphasized, "Security teams need to see their environment the way an attacker does, not the way a scanner does."

Index Ventures' Juriaan Duizendstraal highlighted how Astelia enables CISOs to align security with business priorities through provable exposure.
