Generate a CSR code

CSR stands for Certificate Signing Request, a block of encrypted text containing your contact details such as domain and company identity. When applying for an SSL certificate, you must submit the CSR to your CA for validation. Along with the CSR you will also generate the private key which will remain on the Sophos system.

You have two options:

  1. Use our CSR Generator to create the CSR automatically
  2. Follow our step-by-step tutorial on how to generate CSR in Sophos XG Firewall

Install an SSL certificate on Sophos XG Firewall

Once you’ve received the necessary SSL files from your CA, you can begin installing them. Sophos XG Firewall accepts SSL certificates signed by multiple CAs in .pem or .der format.

Here’s what you will need:

  • Your SSL Certificate in .pem or .der format: It resides in the ZIP folder you received from your CA
  • Your private key: You’ve generated it along with the CSR code on the Sophos XG Firewall server
  • CA passphrase: the password for your private key

To add your SSL Certificate to Sophos XG Firewall, perform the following:

Navigate to Certificates > Certificate Authorities and click Add.

Configure the fields as shown below:

  • Name: enter a friendly name for your certificate
  • Certificate File Format: from the drop-down list, select PEM or DER
  • Certificate: click browse and import your SSL Certificate
    Note: If you’ve generated the CSR code for your SSL Certificate on Sophos XG Firewall, you don’t need to import the private key and enter a CA passphrase. Your private key is already on the Sophos system
  • Private Key: click browse and import your private key
  • CA Passphrase: enter the CA passphrase

Your SSL Certificate should be now listed under Certificate Authorities.
