Very Good Security

Very Good Security (VGS) is a data security and payments infrastructure company that lets organizations operate on sensitive data — payment card numbers, bank accounts, PII, and other regulated information — without the cost or liability of storing it themselves. Its core Vault tokenization platform substitutes sensitive values with format-preserving aliases so customer systems never touch raw data, dramatically reducing PCI DSS, SOC 2, HIPAA, and GDPR compliance scope. VGS also offers Zero Data (a proxy that keeps the customer environment entirely out of PCI scope), a Card Management Platform (network tokens, account updater, 3D Secure), and VGS Control for compliance automation. The developer surface includes the Vault HTTP API for aliases/tokenization, VGS Collect and VGS Show client SDKs, a Terraform provider, and the vgs-cli command line tool. Founded in 2015, VGS is backed by a16z and stores over 5 billion tokens.

Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.

Kin Score

API Evangelist profiles Very Good Security the way a machine reads it — 7 machine-readable artifacts across 1 API, 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 — Very Good Security scores 65.6/100 (strong), with a separate agent-readiness read of 61/100 (agent native). 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 Very Good Security

Each block below is one kind of artifact we hold for Very Good 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.

APIs 1

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

Very Good Security aliases API

Unique IDs that retain all the essential information about the data without compromising its security.

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Event Specifications 1

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

AsyncAPI definitions for this provider's event-driven and streaming APIs.

Security Posture 3

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.

Scopes 1

OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.
