Let's Encrypt vs Paid SSL Certificates: Which Is Right for You?

Let's Encrypt transformed the SSL landscape by making certificate issuance free and fully automated. But paid certificates from DigiCert, Sectigo, and others still exist for good reasons. Here's how to decide.

When Let's Encrypt Is the Right Choice

Let's Encrypt is the right choice for most sites. It issues Domain Validation (DV) certificates with 90-day validity, renewable automatically via Certbot or your hosting provider. It's trusted by all modern browsers and handles hundreds of millions of certificates.

Use Let's Encrypt when: you're running personal projects, developer tools, blogs, APIs, or any site where domain-only validation is sufficient and automated renewal is feasible.

When a Paid Certificate Makes Sense

Paid certificates offer features Let's Encrypt doesn't:

• Organization Validation (OV) — embeds your verified organization name in the certificate. Required by some compliance frameworks.
• Extended Validation (EV) — maximum identity assurance, required by some financial regulations and high-trust contexts.
• Longer validity with manual control — some enterprise environments can't use automated renewal and need 1-year certificates on a controlled schedule.
• Warranty — commercial CAs offer financial warranties (rarely invoked in practice, but contractually meaningful for some organizations).
• Support SLAs — human support for complex issuance scenarios.

What About ZeroSSL and Google Trust Services?

ZeroSSL offers free DV certificates via the ACME protocol, with Let's Encrypt as a fallback. Google Trust Services also offers free ACME-issued certificates for Google Cloud users. These are legitimate alternatives to Let's Encrypt for DV use cases.

Comparing in the Decoder

Paste any certificate into the SSL Certificate Decoder to see which CA issued it, what validation type it is, and what OIDs are embedded in the Certificate Policies extension. DV certificates from Let's Encrypt will look different from OV/EV certificates from commercial CAs in the Subject and extensions fields.
