Neil mentioned they're offering free 90-day single domain certs, but nothing I can find on their site can verify that claim.
From their What Is the ACME Protocol page:
Granted, it says "purchased" here. So maybe that's the confusion. But it also says:
Which types of certificates can I order from SSL.com with ACME?
The following SSL/TLS certificate products may be ordered via the ACME protocol by any SSL.com customer:
• Basic SSL
• Wildcard SSL
• Premium SSL
• Multi-Domain UCC/SAN SSL
The Basic SSL page describes a "single domain" cert (including a www SAN) for "As low as $36.75/year".
Further, their SSL/TLS Certificate Issuance and Revocation with ACME page says this:
All SSL/TLS certificates issued via ACME by SSL.com are one-year certificates. The SSL.com certificate type you will receive (and be billed for) depends on the number and type of domain names requested:
I added the emphasis on "and be billed for". So going strictly by the docs I was able to find. It sounds like they're only offering an ACME compatible endpoint for their existing paid cert offerings. If they offer anything for free, they definitely seem to be hiding it.
I haven't bothered to create an account with them yet. But can anyone confirm the availability of a free option (and if possible point to some sort of official doc talking about it)? It feels like if I had an account with any sort of payment method attached and ordered a single domain cert via ACME, I'd be automatically charged the normal price for a one-year cert.
