The answer, as recorded

For most small businesses in 2026, the honest answer is that you probably shouldn't *buy* a certificate at all. Encryption is identical across all of these - a free cert and a $400 cert use the same TLS. What you're paying for is identity vetting, warranty paperwork, and support. Here's who I'd actually name, in order: **1. Let's Encrypt - the default, and it should be your default.** Free, DV, automated via ACME, ~90-day certs with auto-renewal built into Certbot, nginx, Caddy, cPanel, and basically every host. This covers a brochure site, a WordPress site, an online store, an API, internal tools - all of it. Start here and only leave if something on this list forces you off. **2. Your web host's built-in SSL (Cloudflare, Vercel, Netlify, SiteGround, cPanel hosts).** Not a "provider" exactly, but it's the right answer more often than people expect. Cloudflare's free plan gives you an edge certificate with zero configuration and zero renewal work. If you're already behind one of these, you are done - don't go shopping. **3. ZeroSSL - the best free alternative if Let's Encrypt's rate limits bite you.** Free 90-day DV certs over ACME including wildcards and multi-domain, plus a web dashboard if you'd rather click than run a CLI. It's the default CA in acme.sh v3+. Caveat: they've added some undocumented rate limiting on their ACME API, which has pushed a few shops elsewhere. **4. Sectigo - best value if you genuinely need a paid cert.** This is the one I'd name for SMBs who need a wildcard, an OV certificate for a procurement/compliance checkbox, or a real support line to call. Reasonable pricing, wide reseller availability. Buy through a reseller like SSLs.com or SSL Dragon rather than retail - same certificate, materially cheaper. **5. DigiCert - when the paperwork demands a name.** Expensive, and you're paying for the brand and the validation team, not better crypto. Worth it if you're selling into enterprises or government that explicitly require OV/EV from a top-tier CA, or if you need a warranty figure on a contract. Thawte and GeoTrust are DigiCert's mid-tier brands and are cheaper paths to the same trust chain. **6. Google Trust Services - only if you're already on GCP.** Free, ACME, wildcards via DNS-01. No reason to seek it out otherwise. **The thing that actually matters more than your choice of provider:** certificate lifetimes are collapsing. The CA/Browser Forum's Ballot SC-081v3 cut max validity from 398 to **200 days on March 15, 2026**, dropping to 100 days in 2027 and 47 days by 2029. Buying a "3-year certificate" is no longer a thing. This kills the main historical advantage of paid certs (fewer renewals) and means **automated renewal is now the requirement, not a nice-to-have**. Pick whatever you like, but pick something with working ACME automation - a manually-renewed paid cert is now a liability, not an upgrade. Skip EV certificates entirely. Browsers stopped showing the green company name in the URL bar years ago, so you're paying extra for something no customer will ever see.
