Sectigo (Comodo)
Pros
- + Deep catalog: DV, OV and EV in single-domain, wildcard and multi-domain formats plus code signing
- + Aggressive reseller pricing — PositiveSSL DV from about $7.45/year, OV from about $30/year
- + 99.6% browser and device compatibility from a publicly trusted root
- + Unlimited server licenses, free reissues, 30-day money-back across the range
- + Mature reseller program and certificate lifecycle management tooling for volume buyers
Cons
- - Channel pricing is chaotic — the same certificate varies 3-5x between resellers and the official store
- - OV/EV validation routinely runs 1-5 business days once documentation is submitted, with recurring support complaints
- - Multi-year subscriptions are prepaid one-year certificates requiring annual reissue, which confuses buyers
- - Comodo-era budget brand perception trails DigiCert in enterprise procurement
- - DV-only use cases are undercut by free automated certificate authorities
ZeroSSL
Pros
- + Genuine free tier with no credit card: 3 × 90-day certificates plus multi-domain, wildcard and ACME support
- + Strong automation story for a UI-first CA: REST API, ACME clients, monitoring and installation checks
- + Vienna-founded CA (2016) backed by HID Global since 2024, with a clear enterprise path for OV/EV and lifecycle management
- + Transparent published pricing including fixed Platinum tiers up to $6,719.90 per year
Cons
- - Paying for DV certificates is hard to justify when Let's Encrypt is free and equally trusted in browsers
- - Vendor's own pages disagree on free certificate count and on issuance/client volume
- - No published uptime SLA outside HID's enterprise offering; support priority scales with plan price
- - Credit-based annual certificate quotas and Basic/+ Protect variants make the plan matrix hard to compare
