"Truly, any big number multiplied by an imaginary number can be turned into an even bigger number."
But "imaginary number" is a term with a defined meaning: some real number multiplied by the square root of -1. So a big number multiplied by an imaginary number yields another imaginary number. It's still rhetorically apt though, since imaginary numbers defy common sense definitions of "positive" and "negative," much like Uber's balance sheet.
During #sstic conference (FR infosec reference con), I have done a lightning talk about benefits you can have to deploy an #ACME frontend (Serles ACME proxy in our case) in front of your private PKI in your private corporate network.
One main #takeaway is the great diversity it exists among ACME clients due to its open and standardised format. This diversity in terms of languages and technologies allows a lot of different people among our internal IT ecosystem (developers, sysadmins, devops, architects, network guys...) to adopt ACME.
The final result is a greatly wider adoption of certificates automation inside our private network and a less work for Security team. With zero change (organisational nor added people ) on the PKI side.
