Introduction: The HTTPS Revolution and the SSL Dilemma
In a recent blog post, we discussed Google’s latest security update set to mark all HTTP websites as “Not Secure” starting July 2018. To ensure your website is recognized as secure and avoids the stigma associated with HTTP, installing an SSL certificate is imperative. However, the choice between Let’s Encrypt and a paid SSL certificate remains a critical decision.
Our previous post introduced the options of opting for a paid SSL certificate or installing a free one with Let’s Encrypt. However, it didn’t delve into the nuances, advantages, or disadvantages of each. If you’re seeking clarity on what Let’s Encrypt is, how it differs from a paid SSL certificate, and which is best for your website, continue reading. Here, you’ll find all the information you need to dispel any doubts!
Understanding SSL Certificates: A Quick Overview
An SSL certificate (Secure Sockets Layer) is a security protocol based on a digital signature, facilitating the encryption of data transmitted between the server and the user’s web browser.
Having an SSL certificate transforms your website’s address from HTTP to HTTPS, displaying a padlock symbol and a “Secure” notice. This not only boosts your website’s SEO but also instills trust in your customers, enhancing conversions.
Let’s Encrypt: The Free SSL Certificate
In 2016, Let’s Encrypt was launched as an initiative by the Linux Foundation to foster a more secure web. Let’s Encrypt operates as a certificate authority, issuing free, automatic, and open SSL certificates. Collaborators in this venture include major companies like Google, Automattic, Facebook, and Mozilla, among others.
Over time, Let’s Encrypt has become a viable alternative for those seeking to enhance their website’s security and avoid Google’s “Not Secure” label. As depicted in the graph below, the issuance of Let’s Encrypt certificates has steadily increased since its inception in early 2016.
Let’s Encrypt vs. Paid SSL Certificate: Decoding the Differences
As often seen, free versions of a product tend to have limitations compared to their paid counterparts, or paid services offer unique value additions. The comparison between Let’s Encrypt and paid SSL certificates is no exception.
1. Issuance Speed:
- Paid SSL Certificate: After purchase, a paid SSL certificate, such as those issued by Comodo, requires domain validation before installation. While this process is nearly instantaneous, Extended Validation (EV) SSL certificates may take longer due to additional owner validation.
- Let’s Encrypt: No similar validations occur, making the issuance entirely automatic, allowing you to have your certificate within seconds.
The rapid, automated issuance of Let’s Encrypt certificates has, however, raised concerns about potential misuse due to its ease of acquisition and cost-free nature, as highlighted by security firms like Trend Micro.
2. Price:
- Let’s Encrypt: Free of charge.
- Paid SSL Certificate: Cost involved.
Price is often a deciding factor, but understanding the differences is crucial for an informed decision. Let’s Encrypt may suffice in some cases, but in others, a paid option might be necessary.
3. Support:
- Paid SSL Certificate: 24/7 technical support is available, ensuring prompt assistance for any SSL-related issues.
- Let’s Encrypt: Being a free service, there is no dedicated technical support. However, a robust community and documentation are available for guidance.
While paid SSL certificates offer continuous technical support, Let’s Encrypt relies on its community and documentation for assistance.
4. Green Padlock and HTTPS:
- Let’s Encrypt: When configured correctly, Let’s Encrypt ensures encryption of all transferred information, displaying a secure connection similar to paid SSL certificates.
- Paid SSL Certificate: Provides a recognizable trust seal from the issuing authority, such as Comodo, reinforcing customer trust.
The visual indication of a secure connection is similar for both Let’s Encrypt and basic paid SSL certificates.
5. Certificate Varieties:
- Let’s Encrypt: Offers a single certificate.
- Paid SSL Certificate: Provides a range of certificates, including WildCard for multiple subdomains and Extended Validation for added security and trust.
Paid SSL certificates offer versatility with different types catering to varied website needs.
6. Browser Compatibility:
- Let’s Encrypt: Recognized by major browsers like Chrome, Firefox, and Safari, but potential compatibility issues with older browsers or operating systems due to its relatively young project status.
- Paid SSL Certificate: Generally boasts widespread compatibility across browsers and operating systems.
Paid SSL certificates typically ensure broad compatibility, while Let’s Encrypt may face challenges with certain configurations.
7. Trust Seal:
- Let’s Encrypt: Being a free service, it lacks a specific trust seal.
- Paid SSL Certificate: Includes a trust seal from the issuing authority, adding credibility to your website.
The trust seal associated with paid SSL certificates contributes to user confidence and recognition.
8. Warranty:
- Let’s Encrypt: Being a free service, it doesn’t provide a warranty in the event of encryption breaches.
- Paid SSL Certificate: Offers a warranty, providing financial coverage in the rare event of a security breach.
Paid SSL certificates, even at a basic level, often come with a warranty, offering financial protection against security breaches.
Conclusion: Making an Informed Decision for Your Website’s Security
In conclusion, the choice between Let’s Encrypt and a paid SSL certificate involves weighing the factors that matter most to your website. While Let’s Encrypt caters to many with its simplicity and cost-effectiveness, paid SSL certificates offer additional features, support, and warranties that might be essential for certain businesses.
