Sectigo (Comodo)
0 reviews
Sectigo (Comodo) is rated higher (3.6 vs 3.5). OV/EV and full certificate lifecycle management are offered through parent company HID Global's Enterprise SSL product, not as standard ZeroSSL plans. Sectigo (formerly Comodo CA) is one of the largest SSL certificate providers. DV certificates from about $7.45/year and OV from about $30/year on the reseller channel (higher direct), plus wildcard and multi-domain certificates. Good reseller program.

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
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
