Best enterprise-grade AI agent integration providers in 2026

As AI agents increasingly require connections to external APIs for tasks such as payment refunds or Salesforce updates, enterprises seek secure, compliant, and easily integrable platforms. This text reviews six integration platforms for enterprise AI agents: Nango, Arcade, Composio, Pipedream Connect, Workato, and Paragon. Each platform offers unique features tailored to different needs, such as compliance with SOC 2, GDPR, and HIPAA, customization capabilities, and deployment options. Nango stands out with its extensive API coverage and enterprise readiness, offering 900+ APIs and 6,000+ pre-built tool calls, along with the ability to self-host in any region via bring-your-own-cloud. It is open source, allowing for auditing, and provides robust security and governance features. Arcade, Composio, and other platforms cater to more specific use cases but may have limitations in areas like compliance, audit logging, or maintenance status. The importance of integration platforms lies in their ability to manage OAuth handshakes, credential storage, execution with user credentials, and maintaining an audit trail, which are critical for security reviews and procurement processes in enterprises.
