PreVeil

PreVeil is a Boston-based end-to-end encrypted email and file-sharing platform built for organizations that must protect Controlled Unclassified Information (CUI) and meet CMMC 2.0 Level 2, DFARS 252.204-7012, ITAR, NIST SP 800-171, HIPAA and GDPR obligations. Its architecture removes the central point of compromise: every message and file is encrypted on the endpoint with per-user keys the service never holds, privileged administrative actions require multi-party cryptographic consent through Approval Groups, and there are no passwords to phish. The platform ships PreVeil Drive (encrypted file sharing and sync through Windows Explorer, Mac Finder or a browser), PreVeil Email (which layers onto existing Outlook, Apple Mail and Gmail clients), PreVeil Express for free browser-based external collaboration, an Admin Console with tamper-proof activity logging, e-discovery and device management, a licensed SIEM Connector appliance that exports those logs in syslog format, and a Compliance Accelerator and GRC platform for CMMC documentation. PreVeil publishes no public developer API, SDK or OpenAPI definition; its documented programmatic surface is the first-party PreVeil Drive Upload command-line tool and the SIEM Connector.

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 PreVeil the way a machine reads it — 4 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 — PreVeil scores 35.3/100 (thin), with a separate agent-readiness read of 3/100 (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.

No API surface

Why this profile is thin

PreVeil ships end-user encrypted email and file-sharing clients and publishes no developer program at all — there is no api./developer./docs. host in DNS, /openapi.json and every /.well-known/ path 404 on www.preveil.com, the web.preveil.com SPA answers 200 with an HTML shell for every path including /openapi.json and /.well-known/agent-card.json, and a full-text search of PreVeil's own Confluence knowledge base for "API" returns one hit that is an Android API-level requirement; the only documented programmatic surfaces are a bundled Drive Upload CLI that talks to a machine-local daemon and a licensed SIEM Connector appliance that exports logs as syslog.

This is an honest zero, not a gap in our research. PreVeil does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile PreVeil

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

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 things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.

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.

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.

Where this information came from

This is an independent, third-party profile of PreVeil, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
