Cybersecurity firm Astelia has secured $35 million in combined seed and Series A funding to accelerate development of its artificial intelligence platform designed to help organizations identify and prioritize the most critical security vulnerabilities.
The funding round was led by Index Ventures and Team8, with participation from additional investors, as the company seeks to scale its technology and expand adoption among large enterprises, including Fortune 500 customers.
Founded by veterans of Israel’s National Red Team, Astelia focuses on exposure management, a cybersecurity approach that aims to determine which vulnerabilities pose real risk rather than treating all threats equally. The company’s platform uses agent-based AI to analyze an organization’s network environment, including topology, segmentation, and existing security controls, to identify vulnerabilities that attackers are most likely to exploit.
Security teams face an increasingly complex landscape, with organizations encountering an average of 135 new vulnerabilities each day, according to the company. At the same time, AI-powered cyberattacks are accelerating exploitation timelines, with roughly a quarter of successful breaches occurring within 24 hours of a vulnerability becoming public.
Astelia’s system seeks to cut through that volume by correlating exploitability with real-world access paths, highlighting the small fraction of vulnerabilities that could lead to significant exposure. In some deployments, millions of identified vulnerabilities were narrowed to only a few dozen that posed genuine risk, enabling targeted remediation efforts.
Chief Executive Officer Alon Noy said the platform was designed to help defenders view systems from an attacker’s perspective rather than relying solely on automated scanning tools. Investors noted that as artificial intelligence transforms both offensive and defensive cyber capabilities, enterprises must shift from assessing theoretical risk to measuring actual exposure.
The company plans to use the new capital to enhance its AI-driven analytics, expand engineering and research teams, deepen technology partnerships, and grow its global go-to-market operations.
Industry analysts say the funding reflects rising demand for cybersecurity solutions that can prioritize threats in real time as organizations contend with expanding attack surfaces and increasingly sophisticated adversaries.
As the pipeline of vulnerabilities grows and cyber threats evolve, tools that enable organizations to focus on the most critical risks may become central to enterprise security strategies in the coming years.
