Astelia raises $35M to power AI exposure management for CISOs

Astelia has announced $35 million in seed and Series A funding to expand its AI-based exposure management platform. The funding round was led by Index Ventures and Team8, with additional support from Holly Ventures, and the New York-based startup was founded in 2014 by Alon Noy, Nadav Ostrovsky, and Roy Rajwan.

Astelia’s platform uses AI to model networks, map enterprise environments, and prioritise remediation of critical vulnerabilities, correlating exploitability with real-world attack paths to identify what actually exposes organisations. The company plans to use the fresh capital to enhance its AI-driven analysis, advance attack-path modelling, scale deployments, and deepen partnerships, while also hiring across engineering, research, and global go-to-market teams.

According to Index Ventures, the investment represents a strategic move as AI reshapes attacker capabilities and defensive expectations, helping CISOs align cybersecurity with business priorities and move from reactive patching to preemptive defence. 25 February 2026
