Let's Encrypt vs Paid SSL Certificate: Which is Right for You?

Free or Paid? Choosing the Right SSL

One of the most frequently asked questions when choosing an SSL certificate: "Is Let's Encrypt free SSL sufficient, or should I get paid SSL?" The answer to this question varies depending on your site type, business model and security needs.

In this article, we will help you make an informed decision by objectively comparing both options.

What is Let's Encrypt?

Let's Encrypt is a certificate authority that provides free and automatic SSL certificates, launched in 2016 by the Internet Security Research Group (ISRG). Its goal is to remove the cost barrier to using SSL to make the web more secure.

Let's Encrypt Features:

• Completely free DV SSL certificate
• 90-day validity period (with automatic renewal)
• Automatic installation and renewal with ACME protocol
• Easy management with tools like Certbot
• Wildcard certificate support (with DNS validation)

Differences Offered by Paid SSL Certificates

1. Verification Levels

Let's Encrypt can only offer DV (Domain Validation). Paid SSL certificates offer three levels of verification:

• DV SSL: Domain ownership verification
• OV SSL: Organizational verification
• EV SSL: Extended (highest level) authentication

2. Financial Guarantee

This is one of the differences. Paid SSL certificates come with a warranty whose amount depends on the product. This warranty applies, under the certificate authority's terms, to losses caused by a certificate that was issued incorrectly.

Let's Encrypt offers no financial guarantees.

3. Technical Support

Paid SSL certificate providers offer professional support for installation, configuration and troubleshooting. Only community forums and documentation are available on Let's Encrypt.

4. Certificate Validity Period

• Let's Encrypt: 90 days (automatic renewal required)
• Paid SSL: At most 200 days (since 15 March 2026; this limit drops to 100 days on 15 March 2027 and to 47 days on 15 March 2029). Multi-year plans can still be purchased; the certificate is reissued within the term

The 90-day period is no problem when the automation works properly. However, in case of server changes, DNS problems or automation errors, your site may temporarily remain without SSL.

5. Compatibility

Let's Encrypt is compatible with the majority of modern browsers. However, some older devices and systems (especially IoT, old Android versions, some enterprise gateways) may experience problems.

Paid SSL certificates usually offer broad browser and device compatibility that also covers older devices.
