How to configure UniFi SSL certificate

Published onMarch 10, 2024

SSL certificates encrypt the data transmitted between your browser and the UniFi Controller, ensuring that sensitive information remains secure. Setting up SSL certificates is a critical component for securing UniFi Controllers and their managed networks.

Especially for MSPs and IT-service businesses that run larger networks for multiple clients, security is of utmost importance. Hence, it's essential to figure out how to set up SSL certificates correctly.

We'll run you through a step-by-step guide to set it up. Let's dive in!

The Need for SSL Certificates

SSL (Secure Sockets Layer) certificates are digital certificates that provide authentication for a website and enable an encrypted connection. For UniFi Controllers, an SSL certificate is not just a layer of security; it signifies the legitimacy and safety of your network management portal, especially when accessing it over the internet.

Steps to Configure SSL Certificates for UniFi Controller

  1. Generate a Certificate Signing Request (CSR): Begin by creating a CSR on the server that hosts your UniFi Controller. This request will include your organization’s details, such as domain name, company name, locality, and country.

  2. Choose a Certificate Authority (CA): Submit your CSR to a trusted CA. The CA will validate your domain and organization before issuing an SSL certificate. You can choose from various CAs, including free options like Let's Encrypt or paid ones offering extended validation certificates.

  3. Install the SSL Certificate: Once you receive your SSL certificate from the CA, install it on the server hosting your UniFi Controller. The installation process may vary depending on your server’s operating system and web server software.

  4. Configure the UniFi Controller to Use the SSL Certificate: After installing the certificate, you’ll need to configure your UniFi Controller to use it. This typically involves editing the UniFi Controller’s network settings to point to the certificate files on your server.

  5. Verify the SSL Certificate Installation: Use online tools like SSL Labs' SSL Server Test to check that your UniFi Controller is correctly using the SSL certificate. This tool will also provide a security rating for your setup.

  6. Renew Your SSL Certificate: SSL certificates have an expiration date. Ensure to renew your certificate before it expires to maintain your UniFi Controller’s security and accessibility.

Best Practices for SSL Certificate Management

  • Automatic Renewal: If you're using a service like Let's Encrypt, set up automatic renewal to avoid certificate expiration.
  • Strong Cipher Suites: Ensure your server is configured to use strong cipher suites to enhance the security of the SSL connection.
  • Regular Updates: Keep your UniFi Controller and server’s operating system up-to-date to mitigate potential security vulnerabilities.
