GlobalSign
Pros
- + 25+ years as a publicly trusted CA with ubiquitous roots and WebTrust accreditation since 2001
- + Full identity spectrum: DV, OV, EV, Wildcard, SAN (up to 100 names), plus code signing, S/MIME, and document signing
- + Enterprise PKI depth: Managed PKI portal, Atlas platform, ACME and lifecycle automation tools
- + Warranties scale with validation ($10k DV to $1.5M EV); unlimited server licensing and reissues
- + 24/7 phone, email, and chat support; eIDAS and PSD2 compliance certificates available
Cons
- - Expensive for commodity TLS — $249/yr list for DV against free Let's Encrypt automation
- - Storefront prices render client-side and ordering is region-locked, which complicates buying
- - EV's browser-visible value has eroded; the $599 tier buys vetting and warranty, not a green bar
- - GMO Internet Group ownership is a jurisdiction consideration for some procurement policies
acme.sh
Pros
- + Free GPLv3 tool with no runtime dependencies beyond a POSIX shell — runs on servers, routers, NAS boxes, and containers alike
- + Broadest DNS-01 provider coverage of any ACME client, plus DNS alias and stateless modes for awkward zones
- + Wildcard, SAN, RSA and ECDSA (default) certificates with HTTP-01, DNS-01 and TLS-ALPN-01 challenge support
- + Multi-CA support (Let's Encrypt, ZeroSSL default, Google Trust Services, SSL.com, Actalis) with a single --server flag
- + Self-installing daily renewal cron and deploy hooks with service reload commands — automation once configured
Cons
- - No support contract, no SLA, and community-only help (wiki, GitHub issues, Gitter) when renewals break
- - Learning curve beyond the basic case: shell flags, environment credentials, DNS propagation behavior
- - DNS API tokens stored on the renewing host are a standing credential — scoping and protecting them is on you
- - GPLv3 copyleft complicates embedding in closed commercial products
- - High maintainer concentration and the curl|sh install idiom warrant release pinning and verification in production
