Comparison
GlobalSign lands on Depends, and Let's Encrypt lands on Worth it.
Buy if you're an enterprise needing managed PKI, IoT device identity, or compliant digital signatures at scale.
Buy if you run any public website or API and can operate an ACME client . it's free and the de facto default.
| Compare | ||
|---|---|---|
| Verdict | Depends | Worth it |
| Best for | Enterprises needing managed PKI | Public websites and APIs |
| Who it's not for | Small blogs needing one SSL cert . free options exist | Enterprises needing EV/OV certificates for compliance or branding |
| Privacy | Established CA with no recent breaches, but a 2016 revocation error and 2021 signing-process criticism.⁴ | Widely trusted nonprofit CA; isolated incidents disclosed and resolved openly, no evidence of CA-level compromise in sources reviewed.16 |
| Support quality | No reliable review signal in sources | Community forums only; no paid support |
| Public sentiment | Signal is thin: a 95% Peer Insights recommendation rate on the vendor's own page, offset by developer complaints about code-signing revocations.² | Sysadmins and developers on Reddit largely call Let's Encrypt good enough for production, praising cost and automation while flagging rate limits and renewal discipline.12 |
| Biggest gotcha | Code-signing revocation complaints from developers . protect your keys and read revocation terms first⁶ | Short-lived certs: if renewal automation breaks, your site goes dark without warning. |
