Certificate Management

Last modified: January 27, 2026

Introduction

In Mendix Cloud, SSL/TLS certificates enable secure HTTPS communication for incoming connections to applications that use custom domains.

The Certificate Management page provides Mendix Admins with a centralized view of all company-wide certificates. From this page, you can upload, replace, renew, and monitor certificates that can be reused across multiple applications and environments.

After a certificate is added:

  • Technical Contacts can select it when configuring custom domains at the application level
  • The certificate is shown as centrally managed in the Custom Domains tab of the environment’s Cloud Settings
  • The same certificate can be reused across multiple applications and environments, provided the domain names are covered by the certificate

Certificate Summary

The Certificate Management page displays a summary of all configured certificates, including:

  • Certificates currently in use
  • Certificates not in use
  • Expired certificates
  • Certificates that are about to expire

This overview helps you proactively manage certificate renewals and avoid service interruptions.

Certificate Details

Each configured certificate is shown in a table with the following fields:

  • Description – A descriptive name for the certificate. Use clear and meaningful names to make certificates easy to identify.

  • Expiration date – The date and time the certificate expires

  • Number of custom domains – The number of custom domains currently using the certificate

  • Status – The current state of the certificate:

    • Valid – Currently valid and in use
    • Expires soon – Certificate expiring soon
    • Expired – Certificate has expired
    • Upcoming – Certificate is not valid; the start date is in the future

    You can filter certificates by these statuses to identify certificates that require renewal or deletion.

  • More options – Actions available per certificate:

    • Edit
    • Replace
    • Details
    • Delete

For detailed information about how Mendix Admins can use the Certificate Management page to upload, configure and manage centralized certificates, refer to Centralized Certificates.
