There's a scale beyond which the real challenge isn't issuing a certificate.
I see organisations with thousands of SSL certificates, and their struggle is real. Even reputable companies with huge teams have their certificates expire or served badly. Some serve expired certificates for years!
Plus, enterprise alternatives are extremely costly and rigid.
All the more reason to automate renewing of certificates.
Sure! yet automation only solves one problem (until it doesn't). Inventory and control/accountability is still needed at scale, and automation doesn't provide it.
