Cybersecurity startup Astelia has announced raising $35 million in seed and Series A funding. The investment was led by Index Ventures and Team8, with additional support from Holly Ventures.
The company was founded in 2014 by former Israeli national red team leaders Alon Noy (CEO), Nadav Ostrovsky (CTO), and Roy Rajwan (CPO).
New York-based Astelia has built an exposure management platform that helps organizations identify and prioritize the remediation of critical vulnerabilities.
The company leverages AI for deep network modeling, mapping the enterprise environment, segmentation, and security controls to identify where exploitation is most likely to occur.
The platform correlates the exploitability with real-world attack paths, identifying the vulnerabilities that truly expose the environment to attacks.
It also provides organizations with environment-specific remediation plans, reducing exposure while eliminating unnecessary patch deployments.
Astelia will use the fresh investment to expand its platform’s AI-driven analysis capabilities, advance attack-path modeling, scale deployments, and deepen partnerships.
It also plans to hire new talent across the engineering, research, and global go-to-market teams.
“As AI reshapes both attacker capabilities and defensive expectations, the strategic imperative for enterprises is to move from assumed risk to provable exposure,” said Index Ventures partner Juriaan Duizendstraal.
“Solutions that show where organizations are actually exposed enable CISOs to align cybersecurity with business priorities, reduce wasted effort, and turn vulnerability management from a reactive scramble into a preemptive defense,” Duizendstraal added.
