Sophos Factory: Upload LetsEncrypt Certificates on SFOS via Factory

LuCar Toni

Sophos Factory offers pre build pipelines to upload and manage certificates on a Sophos Firewall. 
For example can you upload and use Certificates like LetsEncrypt Certificates in SFOS with those Pipelines. 

If you have a Certificate already generated like described here:  [HowTo] Lets Encrypt Renewal Process with Factory 

You can simply use those certificates with the predefined Pipelines. You find them in the global catalog:

This Pipeline require the following Inputs:

Which could be extracted by a pipeline before that. Like this one:  [HowTo] Lets Encrypt Renewal Process with Factory 

In combination: 

Which will upload the certificate to the firewall. 
To integrate the Firewall, please follow the following: Sophos Factory: Integrate Sophos Factory with Sophos Firewall  

This would be the editor code for everything:

    Would this be appropriate for a partner to deploy and assign certificates across several hundred clients?  Seems like that would be a challenge.  Not a single wildcard cert but a cert for every company.

    As you can scale this, you would generate per customer one certificate and "offer the certificate to the customer". Partners doing this right now. 

    The point here is: The wildcard can be offered directly to the firewall or as multiple approaches. For example you can upload it to the firewall and send it as a S3 Bucket Download to the customer via Email or Teams. So the customer can reuse it manually, if he wants. 

    The customer in the end does one thing (one time config): He creates a CNAME to the partner domain. The rest is automatically generated by lego in this principle. I wrote about this here:  [HowTo] Lets Encrypt Renewal Process with Factory 

    Right now, i am doing this for 20 domains automatically (Upload to firewalls and offering via Teams). 

    Factory offers the way to automate this per domain, per customer individually. Which means: You build the pipeline and then recreate the customer variables one time and run this pipeline per customer automatically every 90 days. 

    It is a service offering from the partner for the customer. Some customers do not need a LE certificate, as they have no public facing services anyway. 

    And as this solution is entirely free, you are free to try it and report back about your findings.
