It's funny you should mention that. A new guy (who has since left) who was super into the Let's Encrypt thing before running up against the org policy of only using a certain certificate vendor, got excited about the "problem," used NGINX, and then had to take it down for reasons I wasn't privy to. I didn't look into the reasons why.
Probably stepped on some toes. If they're not familiar with LE, it's because they think anything free has a catch, or they're just ignorant and want to keep sending money to Norton because that's the antivirus that came with their computer all those years ago.
Oh, the guy who wanted NGINX was familiar with Let's Encrypt, but the org-wide policy was set somewhere far, far away from either of us. The approved vendor changed at least twice that I can recall.
