Astelia Secures $35M in Funding for Cybersecurity Platform

Most security teams wake up to the same horror movie sequel. The scanner screams, the dashboard sweats, and suddenly you are starring in “3M Vulnerabilities and 0 Time,” filmed on location inside a ticket queue that never ends. Attackers love that. Noise is their favorite camouflage.

Astelia came out of stealth in Feb 2026 with a very specific grudge against that chaos, and a very adult solution: proof. Founded in late 2024 through the Team8 Venture Creation model, headquartered in New York with R&D and operations in Israel, and now 30+ people across the US and Israel, Astelia built an AI native exposure management platform that maps real network topology and reachability, then uses agentic AI to decide what is actually reachable and exploitable in your environment.

That word “actually” is doing heavy lifting. Astelia talks about surfacing roughly 2% of vulnerabilities that represent real exposure, then serving evidence based remediation guidance that goes beyond “patch everything and pray.” It is designed to sit alongside the scanners and security tools you already have, not cosplay as a replacement. In coverage, deployments were described as compressing nearly 3M findings down to about 30 that are truly exploitable. That is not a metric. That is a lifestyle change.

Credit where it is due. Congratulations to Alon Noy (Neuhaus), CEO, and Nadav Ostrovsky, CTO, plus Roy Rajwan, CPO, and the whole Astelia team. These are former leaders of Israel’s National Red Team and veterans of the Israeli intelligence community who lived the attacker’s viewpoint long enough to get tired of defenders being forced to play defense with a blindfold and a spreadsheet.

The market agreed with its wallet. Astelia raised $35M total across seed and Series A. The seed was $10M led by Team8 with participation from Holly Ventures. The Series A was $25M led by Index Ventures with participation from Team8 and Holly Ventures. Investor voices like Juriaan Duizendstraal at Index Ventures, Amir Zilberstein at Team8, and John Brennan at Holly Ventures are not just cheering the product, they are underwriting the thesis that exposure is not a score, it is a path.

Astelia says it is already working with dozens of customers, including leading Fortune 500 companies across the United States and Europe, with buyers who live in the real world: CISOs, vulnerability teams, security engineering, IT operations, plus the verticals that cannot afford theater, like finance, healthcare, retail, and telecom. The new capital is earmarked to expand AI driven analysis, scale deployments, deepen technology partnerships, and grow engineering, research, and global go to market teams.

If your vulnerability program still measures success by how many alerts it can generate, what would it look like to measure success by how few exposures remain, and what would your team do with all that reclaimed oxygen.
