What is Letsencrypt?
Letsencrypt is a globally recognized nonprofit certificate authority (CA) that has revolutionized the SSL certificate landscape. Founded by the Internet Security Research Group (ISRG), its mission is simple yet crucial: to make the internet safer by enabling widespread adoption of HTTPS. Letsencrypt has made significant strides in its mission by providing free SSL/TLS certificates to millions of websites worldwide, helping to improve online privacy and security across the internet.
One of the standout features of Letsencrypt is its fully automated certificate issuance process. From requesting a certificate to renewing it, everything is automated, ensuring that website owners don’t have to manually handle the complexities of SSL certificate management.

Key Differences Between ZeroSSL and Letsencrypt
When it comes to choosing between ZeroSSL vs Letsencrypt, it’s essential to understand their key differences in terms of features, pricing, usability, and more. Let’s take a closer look at how these two SSL certificate providers compare on several crucial aspects.
1. Cost
Both ZeroSSL and Letsencrypt offer free SSL certificates, which is an excellent option for individuals and businesses working with a tight budget. Free certificates are a fantastic way to secure a website without incurring any costs, but where these providers differ is in the range of options beyond the free tier.
ZeroSSL, unlike Letsencrypt, also provides paid SSL certificates that come with advanced features like Extended Validation (EV) certificates and Wildcard SSL certificates. These additional certificates allow website owners to access more robust security options and are ideal for businesses that require higher levels of trust from their users. EV certificates are especially valuable for eCommerce websites or online businesses that want to display a high level of credibility and trustworthiness.
On the other hand, Letsencrypt sticks primarily to providing Domain Validation (DV) certificates, which are free but come with limitations. These certificates are suitable for most websites but do not include the extended features that ZeroSSL offers.
In short, if you’re just looking for a free SSL certificate, both providers have you covered. However, if you need specialized certificates with more comprehensive validation options, ZeroSSL has the upper hand in offering paid plans with enhanced features.
2. Ease of Use
Letsencrypt is a powerful SSL certificate authority that offers a streamlined process for issuing certificates. Its strong point is automation through the ACME protocol, which allows website owners to automatically request and renew SSL certificates. This process is great for experienced users and large-scale website operators, especially for those who want to automate their entire SSL certificate lifecycle. However, for beginners, Letsencrypt can pose some challenges. The process requires using command-line tools, server integration, and sometimes even configuring a client to automate the certificate management. This can be overwhelming for those without technical knowledge.
In contrast, ZeroSSL is designed with a more user-friendly approach in mind. Its intuitive interface is perfect for beginners who may not be comfortable using command-line tools or performing complicated server setups. With ZeroSSL, even novice website owners can manage their SSL certificates easily through a visual interface, making the process much more accessible. ZeroSSL also offers ACME protocol integration, so developers who prefer to automate the process can still take advantage of this feature without compromising usability.
Thus, if you’re a beginner or prefer an interface that doesn’t require extensive technical know-how, ZeroSSL is a more user-friendly option compared to Letsencrypt.
3. Validity Period
When it comes to the validity period of SSL certificates, both ZeroSSL and Letsencrypt offer certificates with a 90-day validity period, which is standard in the industry for DV SSL certificates. This relatively short validity period encourages frequent renewals and helps to maintain high levels of security.
However, ZeroSSL provides a bit more flexibility by allowing users to purchase certificates with longer validity periods—up to 1 year for paid plans. This option can be beneficial for users who want to avoid the hassle of renewing their certificates every three months. While this extended validity is convenient, Letsencrypt does not offer this option, and their certificates still expire after 90 days, requiring users to renew them periodically.
So, if you’re looking for an SSL solution that offers longer validity periods, ZeroSSL provides an advantage over Letsencrypt with its extended paid plans.
4. Browser Compatibility
Both ZeroSSL and Letsencrypt are trusted by virtually all modern browsers, offering 99.9% browser compatibility. This means that whether your website visitors are using Google Chrome, Firefox, Safari, or other popular browsers, they won’t encounter any security warnings when accessing your site. This level of compatibility ensures that your SSL certificate is universally recognized and trusted, providing a seamless experience for your users.
Whether you choose ZeroSSL or Letsencrypt, you can rest assured that your SSL certificate will be widely accepted, making both providers reliable choices in terms of browser coverage. So, for website owners looking for the reassurance that their SSL certificates will be trusted across all major platforms, both ZeroSSL and Letsencrypt deliver on this front.

ZeroSSL Features: A Closer Look
When it comes to providing flexible, user-friendly, and secure SSL certificates, ZeroSSL stands out with several unique features that cater to different website needs. Let’s explore these in more detail:
1. Wildcard SSL Certificates
One of ZeroSSL’s most valuable features is its offering of Wildcard SSL certificates. These certificates can protect your main domain and all subdomains associated with it, all under a single certificate. This is incredibly useful for businesses or websites that operate a variety of subdomains and want to save time and money by securing all of them in one go. For example, if you have store.yourdomain.com, blog.yourdomain.com, and shop.yourdomain.com, a Wildcard SSL certificate from ZeroSSL will cover all of them, simplifying the management of SSL security.
2. Extended Validation (EV) Certificates
For businesses looking to increase trust and enhance their website’s credibility, ZeroSSL offers Extended Validation (EV) certificates. EV certificates are the gold standard in terms of trust and security. When you use an EV certificate, the company’s name will appear prominently in the browser’s address bar next to the HTTPS padlock, signifying that the website is secure and trustworthy. This visible trust indicator is especially important for e-commerce and financial websites, as it helps reassure visitors that their sensitive information is being handled securely.
3. ACME Protocol Integration
ZeroSSL also fully supports the ACME protocol, which allows website owners and developers to automate the process of SSL certificate issuance, renewal, and management. This integration enables the seamless automation of SSL processes, especially useful for developers managing multiple websites or servers. By using the ACME protocol, ZeroSSL makes it easier for website administrators to keep their certificates up to date and ensure ongoing security with minimal manual effort.
Letsencrypt Features: A Deeper Dive
While Letsencrypt offers a more streamlined, automated experience for securing websites, its features are more focused on providing basic SSL certificates to meet the security needs of many users. Here’s a closer look at what Letsencrypt offers:
1. Fully Automated SSL Management
One of the strongest features of Letsencrypt is its complete automation. Using the ACME protocol, Letsencrypt makes SSL certificate management completely hands-off. This means that from issuance to renewal, everything can be automated, making it an ideal choice for beginners or anyone who does not want to handle the technical details of SSL certificates manually. The automatic renewal system ensures your certificates stay up to date without needing you to intervene.
2. Free 90-Day Certificates
Letsencrypt offers free SSL certificates with a 90-day validity period. While some might view the short validity as a disadvantage, the frequent renewal cycle is actually a security advantage. Regular renewals ensure that the certificates remain up to date with the latest security features and patches. This frequent renewal also helps encourage website owners to stay on top of their security measures, which is important for maintaining a secure website in today’s ever-changing digital landscape.

ZeroSSL Security Features

EV certificates offer better protection for websites that handle sensitive user data, such as e-commerce websites or financial institutions, by providing an additional layer of authentication to ensure that visitors can trust the website they’re interacting with.
