+description: "Commercial support, certified distributions, and managed services for Dapr"
+---
+
+For organizations running Dapr in production that need enterprise-grade support, service-level agreements (SLAs), certified distributions, or fully managed services, commercial offerings are available from the Dapr ecosystem. The following offerings are provided by [Diagrid](https://www.diagrid.io/), a leading contributor to the Dapr project.
+
+## Dapr open source support
+
+Diagrid provides 24/7 enterprise support for open source Dapr, with a guaranteed one-hour response time for critical production issues. Support is offered across three tiers (Standard, Select, and Premium) with varying response times, security patching commitments, architecture reviews, and training sessions tailored to your organization's needs, across all cloud platforms.
+
+{{< button text="Learn more about Dapr open source support" link="https://docs.diagrid.io/dapr-open-source/dapr-support" >}}
+
+## Diagrid Dapr Distribution for Enterprise (D3E)
+
+D3E is a custom distribution of the open source Dapr project that enhances it with additional security and scalability capabilities, while maintaining full compatibility with the Dapr APIs and SDKs. Designed for large-scale production environments, it offers multi-tenancy support, reduced security permissions, enterprise support with guaranteed response times, and CVE backports to custom versions. It is aimed at organizations with stringent security requirements or substantial Dapr deployments.

+## Diagrid Catalyst
+
+Diagrid Catalyst is an AI orchestration platform that brings durable workflows, access control, and governance to AI agents and MCP servers. It delivers an AI-native workflow engine that integrates with existing agent frameworks, ensuring agents pick up where they left off in the event of any failure, from simple restarts to complete system outages. Catalyst also lets platform teams and developers issue cryptographic identities to agents, MCP servers, and tools, and apply policy-based access control across the organization.
