What problems is ZeroSSL solving and how is that benefiting you?
I intended to use zerossl to provide free 90 days certs to a few small, personal web sites that I operate. Signing up with them was fast and easy, generating the certs was fast and easy, sadly, I never got to even try them as I had an accident and was laid up for a while, and they expired. No problem I thought, I can either renew them now that I am on my feet again or regnerate them if I can not rener them. This is where the problem with zerossl arose. They compare themselves with derivses that are truly free, but when zerossl says they will issues you 3 free ssl certs, they literally mean 3, no free renewals or regeneration of ones that have expired. You get 3 free certs for your lifetime from them. This is far from what some other places give you, totally free 90 certs for as long as you want to renew and deal with them every 90 days. Some of them even have the request, renewal, and install mechanized. Sadly my case is an odd web server and I am not able to use that service, and zerossl was able to give me certs to try and install manually. Review collected by and hosted on G2.com.
