# Official third-party integrations with OVHcloud KMS

**This guide lists the third-party applications officially integrated with OVHcloud KMS and links to their documentation.**

 

## Objective

OVHcloud maintains dedicated integrations for selected third-party applications, such as plugins, operators, and configuration guides. This reference page lists those integrations and links to the documentation you need to set them up.

 

## Requirements

- An [OVHcloud customer account](https://docs.us.ovhcloud.com/en/account/account-information/create-account.md).
- An [OKMS domain](https://docs.us.ovhcloud.com/en/manage-and-operate/kms/quick-start.md) (for most integrations).

 

## Instructions

### Official third-party integrations

The table below is updated as new OVHcloud-maintained integrations are released. Only third-party products with an integration maintained by OVHcloud are listed.

Products compatible via the [KMIP protocol](https://docs.us.ovhcloud.com/en/manage-and-operate/kms/connect-product-using-kmip.md) (VMware, Nutanix, MongoDB, OpenBao, etc.) are not listed here: those integrations are maintained by their respective vendors, not by OVHcloud.
