Nebula Security
Nebula Security is an AI-native cybersecurity company backed by Y Combinator (S26) and founded by world-class hackers — members of a top CTF team, DEF CON winners, Black Hat speakers, and cybersecurity PhDs. Its product, Vega, is an AI security agent that audits codebases for vulnerabilities on the Vega backend, alongside human-led product security auditing. Vega runs from the terminal via the Vega CLI (`vega`), which is distributed as an installable Agent Skill and an npm/global binary, authenticates with an API key or OAuth login, and exposes a project → repository → scan → finding drill-down. The team publishes vulnerability research (e.g. an nginx RCE, CVE-2026-42530) and positions "Audited by Nebula Security" as a product credibility marker.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Nebula Security the way a machine reads it — 2 machine-readable artifacts, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Nebula Security scores 23.0/100 (emerging), with a separate agent-readiness read of 26/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Nebula Security
Each block below is one kind of artifact we hold for Nebula Security. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
