# PreVeil

> PreVeil is an end-to-end encrypted email and file-sharing platform 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. Content 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.

## Important for agents

PreVeil publishes **no public developer API**. There is no OpenAPI or AsyncAPI definition, no GraphQL
endpoint, no MCP server, no A2A agent card, no OAuth or OpenID Connect discovery document, no SDK on
any package registry, and no developer portal. Probes on 2026-08-26 of `www.preveil.com`,
`web.preveil.com`, `collections.preveil.com` and `status.preveil.com` found no machine-readable API
contract. `web.preveil.com` answers 200 with an HTML application shell for every path, including
`/openapi.json` and `/.well-known/agent-card.json`; those are not documents.

PreVeil's two documented programmatic surfaces are:

1. The **PreVeil Drive Upload CLI**, bundled with the desktop client, which talks to the locally
   installed PreVeil drive daemon on the same machine — not to a network API.
2. The **PreVeil SIEM Connector**, a licensed Docker/VM appliance that exports organization activity
   logs in syslog format to an external SIEM. It requires a license and hosting agreement.

Anything presented as a "PreVeil REST API" is not something PreVeil publishes.
