Description

Secure Updates Client is designed to seamlessly integrate with Secure Updates Server, providing a complete solution for managing WordPress plugin updates through your own infrastructure. While it can work with any compatible update server, it offers zero-configuration integration with Secure Updates Server, allowing you to immediately start managing plugin updates through your own trusted infrastructure. The plugin intelligently overrides the update URLs for plugins hosted on WordPress.org while leaving custom-hosted plugins unaffected.

Together with Secure Updates Server, this client enables you to:

• Mirror and serve plugin updates from your own infrastructure
• Ensure plugin integrity through checksum verification
• Control and monitor plugin updates across your WordPress sites
• Maintain a secure, private plugin update channel
• Automatically sync new plugins with your update server

The client can also be configured to work with other mirrored plugin repositories or custom update servers that implement the required API endpoints.
