Kiteworks

Kiteworks operates a Private Data Network (PDN) that unifies secure email, secure file sharing, secure web forms, managed file transfer (MFT), and SFTP behind a single hardened virtual appliance with a common governance, encryption, and audit layer. The platform targets regulated industries — government, defense, healthcare, financial services, legal, manufacturing, and higher education — where sensitive content leaving the organization must be tracked and provably compliant with regimes such as CMMC 2.0, FedRAMP, HIPAA, GDPR, and NIST 800-171. Kiteworks exposes its platform through a versioned REST API (currently v28) covering files, folders, mail, web forms, users, admin, SCIM provisioning, and search across roughly 400 endpoints, plus a PubSub webhook service for real-time event delivery and an Apache-2.0 licensed Model Context Protocol (MCP) server that lets AI assistants operate on Kiteworks content under OAuth 2.1. The company was formerly known as Accellion.

Kiteworks publishes 2 APIs on the APIs.io network: Core API and PubSub Consumer API. Tagged areas include Company, Secure File Sharing, Managed File Transfer, Secure Email, and Data Governance.

The Kiteworks catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Kiteworks’ developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 28 more developer resources.
