Certbot
Pros
- + Free, Apache 2.0, EFF-maintained — no paid tier or usage caps
- + Automates issuance, installation, and renewal for Apache, Nginx, HAProxy, Plesk, standalone, webroot
- + Wildcard certificates via DNS-01 with many first-party DNS provider plugins
- + Works with any ACME CA, not just Let's Encrypt
- + Interactive instruction generator makes correct setup reachable for non-specialists
Cons
- - Assumes root access on a traditional server; poor fit for containers and serverless
- - Renewal failures are silent unless you add monitoring and alerting
- - Config-parsing plugins can refuse complex setups, falling back to manual work
- - Certificates-only scope: no inventory, policy, or contractual support
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
