Astelia

Astelia is an AI-native exposure management and vulnerability management company whose platform helps security teams find and fix the reachable fraction of their vulnerabilities. Using agentic AI and read-only integrations, Astelia maps network topology, extracts the technical requirements an exploit actually needs, and correlates reachability with network context to surface which vulnerabilities are truly exploitable by an attacker. Rather than ranking issues on probability scores alone, it delivers attack-path visualization, coverage-gap analysis, and evidence-based remediation guidance tailored to each organization's environment. Astelia is backed by Index Ventures and documents its security posture in a public trust center (SOC 2 Type 2, ISO/IEC 27001:2022, HIPAA, GDPR). This API Evangelist profile enriches the company as a network lead; the product surface is enterprise SaaS with no public API published at this time.

Astelia is profiled on the APIs.io network. Tagged areas include Company, Security, Vulnerability Management, Exposure Management, and Attack Surface Management.

Astelia’s developer surface includes documentation, engineering blog, signup flow, and 7 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/astelia: open an issue to ask a question, or submit a pull request to add artifacts.
