Zero Trust Network Access

Zero Trust Network Access (ZTNA) is a security framework and product category that grants access to private applications and resources based on identity, device posture, and context, rather than network location. ZTNA replaces the implicit trust of legacy VPNs with explicit per-request verification, creating one-to-one encrypted tunnels between authenticated users and the specific applications they are authorized to use. This topic collects the leading ZTNA vendors, the standards bodies that govern the underlying primitives, and the data schemas used to describe access policies, identities, devices, and resources.

human only

Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.

Kin Score

API Evangelist profiles Zero Trust Network Access the way a machine reads it — 34 machine-readable artifacts across 6 APIs, 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 — Zero Trust Network Access scores 39.1/100 (thin), with a separate agent-readiness read of 14/100 (human only). 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 Zero Trust Network Access

Each block below is one kind of artifact we hold for Zero Trust Network Access. 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 6

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.

Twingate API

Twingate is a software-defined ZTNA platform that exposes a GraphQL Admin API for managing remote networks, resources, groups, users, service accounts, and connectors.

GraphQL 1

Where a provider ships GraphQL, the schema is the contract. We profile it alongside the REST surface so the whole interface is legible in one place.

GraphQL schemas published by this provider.

Pricing Plans 1

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.

Published pricing tiers and plan structures.

Rate Limits 1

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Documented rate limits and quota policies.

FinOps 1

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Features 8

The notable capabilities this provider advertises, captured as structured features so they can be searched and compared instead of read one landing page at a time.

Notable capabilities this provider offers.

Identity-Centric Access

Access decisions are based on user and workload identity rather than network location.

Application-Level Tunnels

One-to-one encrypted connections between authenticated users and specific applications.

Device Posture Checks

Continuous evaluation of device health, OS patch level, EDR status, and certificate state.

Context-Aware Policy

Policies factor in time, location, risk score, and behavior in addition to identity.

Application Cloaking

Private applications are dark to the public internet and not advertised by IP or DNS.

SSO and MFA Integration

Native integration with SAML, OIDC, and modern MFA providers.

Microsegmentation

Lateral movement is prevented by issuing scoped, per-application access.

Continuous Authorization

Sessions are reauthenticated and reauthorized as conditions change.

Semantic Vocabularies 1

JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

JSON Schema 3

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

Examples 2

Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.

Example request and response payloads for these APIs.

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.
