Corelight

Corelight is a network detection and response (NDR) company founded by the creators of the open-source Zeek (formerly Bro) network security monitor. Its Open NDR Platform transforms network traffic into high-fidelity security evidence — logs, alerts, and metadata — powering threat detection, hunting, investigation, and incident response across on-premises and cloud environments. Corelight Sensors expose a comprehensive RESTful API for remote configuration and control, driven by the open-source corelight-client command-line client, with a Fleet Manager for centralized fleet management. Backed by Accel and General Catalyst, Corelight is listed on the FedRAMP Marketplace (In Process, Moderate).

Corelight is listed with 1 API on the APIs.io network. Tagged areas include Company, Cybersecurity, Network Detection and Response, Network Security, and Threat Detection.

Corelight’s developer surface includes documentation, engineering blog, support, pricing, CLI, authentication, and 15 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes

12 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 0.0 — up to +25.0 composite points
Operational Transparency scores 15.8 — up to +10.9 composite points
Access Clarity scores 47.4 — up to +10.5 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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 the provider profile at artifacts.apis.io/corelight/apis.yml: open an issue on github.com/api-evangelist/corelight to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Network Edge (CDN, networking, peering, edge compute)	standard	45.4	-	-
Common Criteria Certified Products (ISO/IEC 15408, NIAP Product Compliant List)	standard	45.4	-	-
NIST CMVP FIPS 140 Validated Cryptographic Modules (FIPS 140-1 / 140-2 / 140-3)	standard	45.4	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
