Astelia, the AI-native exposure management platform, today announced a new partnership with GuidePoint Security.
Through this partnership, GuidePoint customers can use Astelia to map their real network topology, analyze exploit requirements with agentic AI, and pinpoint the ~1 percent of vulnerabilities that are actually reachable and exploitable in their environment. Astelia then applies agentic remediation to those reachable vulnerabilities, giving teams evidence-based paths to fix what matters rather than another backlog to triage.
“Everything about attacks is getting faster, and no team beats that by patching everything faster. Now that frontier AI models can turn a CVE into a working exploit in hours, severity scores say less and less about real risk, and no one is compressing a 30-day patch cycle across thousands of findings into an afternoon,” said Alon Noy (Neuhaus), co-founder and CEO of Astelia. “Reachability analysis is how teams get their footing back. Only about 1% of what a scanner flags is genuinely reachable and exploitable once you account for the real network topology, and the fastest fix often isn’t a patch at all but a configuration or segmentation change that cuts the attack path in minutes. We show enterprises the fraction an attacker can actually reach and let agentic remediation resolve it, so teams stop grading themselves on patch SLAs across the whole backlog and start measuring how fast they mitigate what matters.”
Through the partnership, GuidePoint customers can deploy Astelia on top of their existing scanners. Beyond those scanner findings, Astelia surfaces newly disclosed and zero-day vulnerabilities on its own. Using read-only integrations rather than endpoint agents or active scanning, Astelia maps network topology and correlates each vulnerability’s exploit requirements, including network path, privileges, and dependencies, against how the environment is actually built.
Once Astelia proves what is reachable, its agentic remediation goes to work on those vulnerabilities, generating and driving fixes that reach beyond patching to configuration changes, segmentation, and compensating controls, so security and IT can align on the fastest practical resolution.
“Enterprises don’t have a shortage of vulnerability data. They have a shortage of certainty about which findings actually put them at risk,” said Mark Thornberry, SVP, Partnerships at GuidePoint. “That’s exactly the kind of challenge we help our clients navigate, working alongside partners like Astelia to give security teams evidence-based clarity and a faster path to fixing what counts.”
The partnership builds on Astelia’s continued momentum. The company recently raised $35 million and has signed multiple large enterprise customers, several of which have already renewed their contracts.
