Website security is a paramount factor for every website owner. Thus, TLS/SSL certificates are issued by (CAs) Certificate Authorities. A trustworthy SSL certificate authenticates a website’s identity and enables an encrypted connection. Data encryption is essential to secure communication between the web server and its users. HTTPS symbolizes data encryption which also ensures the increased security of the data transfer.
The Internet Security Research Group (ISRG) is a public organization that focuses on Internet security. No matter what the user’s technical or financial capabilities are, it aims to ensure secure Internet communication.

What is Let’s Encrypt SSL Certificate?
Let’s Encrypt is an automated Certificate Authority (CA) run by the ISRG. It offers X.509 certificates for Transport Layer Security (TLS) encryption. Organizations worldwide can obtain, renew, and manage SSL/TLS certificates through the CA. Websites use them to enable secure HTTPS connections. Let’s Encrypt automatically renews certificates to reduce page errors.
How Does Let’s Encrypt Work?
Let’s Encrypt leverages a protocol called ACME (Automated Certificate Management Environment). This ingenious protocol automates the issuance and renewal of SSL/TLS certificates. It eliminates the manual need and error-prone processes. With Let’s Encrypt, your certificates are automatically renewed every year, so you don’t have to constantly worry about them.
The Types of Certificates Let’s Encrypt Offers
Let’s Encrypt primarily offers DV (Domain Validated) certificates. These certificates are crucial for most of websites, verifying that you have control over the domain, and securing connections effectively. In spite of Let’s Encrypt’s lack of Extended Validation (EV) certificates, most websites, such as e-commerce sites, blogs, and small business pages, find DV certificates to be sufficient for security.
Advantages of Let’s Encrypt Certificates
1. Free of Cost
One of the most significant advantages of Let’s Encrypt certificates is they are free of cost. Conventional SSL/TLS certificates come at a recurring fee or renewal charges. Let’s Encrypt democratizes web security by eliminating financial barriers. Such an accessibility level makes Let’s Encrypt an appropriate option for organizations functioning at a lower budget.
Although Let’s Encrypt is cost-free, it does not compromise with the functionalities. These certificates offer the same level of encryption as paid alternatives, ensuring robust protection for website visitors.
The initiative aligns with its mission to build a safer internet by encouraging widespread HTTPS adoption. Many developers and organizations allocate their funds to other operations in spite of investing into web security.
2. Ease of Automation
Let’s Encrypt automates the tools for getting and renewing SSL certificates. By using ACME (Automatic Certificate Management Environment) protocols, users bootstrap + bootstrap their own installations and renewals automatically.
Automation helps reduce human mistakes like, missed certificate renewal. This will result in a website that is not secure or down. When combined with the web hosting platform, Certbot and such tools automate the process so that it is rather uninteresting to non-technical people.
This reduced friction to automation is especially key for serverless monoliths and any business with hundreds of domains. It lowers the operational overhead but keeps all sites safe without having to constantly babysit.
3. Improved Website Security
Website using Let’s Encrypt to encrypt the information that passes from the website and visitors. It is a shield for their data i.e., the login credentials, personal info and also payment details. It provides confidentiality and integrity of the data, minimizing the risks of breaches to risk and interception.
Let’s Encrypt uses industry-standard encryption ciphers that offer great security, equivalent to paid certificates. It also comes with advanced features, for example, Wildcard certificates, that are helpful for sub-domains below the root of one single certificate.
On top of that, Let’s Encrypt improves user trust. The HTTPS padlock will appear in the browser of your visitors and it gives them a sense that the website is secure. Which when implemented provides higher user engagement, less bounce rate,and esteem for a business.
4. Widespread Compatibility
Let’s Encrypt certificates are hugely compatible with most of the web browsers, devices, and server configurations. Because of such compatibility ensures a seamless user experience across different platforms, reducing potential accessibility issues.
The certificates are also trusted by root programs like Google, Microsoft, and Apple. The wide acceptance kills any chance of browser warnings or compatibility horrors with minor/unknown certificate authorities too.
Also, compatibility is not just positive to the web hosts and CMS because these days even some hosting platforms provide Let’s Encrypt support out of the box. The widespread use cuts down the barrier to entry for security in general (more people are switching to just using secure connections)
5. Promotion of a Safer Internet
Let’s Encrypt contributes crucially to the global movement toward a safer and more secure internet. Opening and providing SSL certificates for free pretty much gets even the little websites on HTTPS, making fewer websites unencrypted data.
It aligns with industry best practices and what search engines (like Google, etc) tend to love when it comes to securing your website. By default, adopting HTTPS, helps against phishing and cyberattacks for the whole digital ecosystem.
Also, Let’s Encrypt is an example of open-source excellence and crowd reimagination. By providing this community-driven framework for security it has encouraged follow-on projects and work to improve the security and usability of the Internet.
How to Get Started with Let’s Encrypt?
This is a step-by-step tutorial that guides you through installing Let’s Encrypt SSL in your domain through the cPanel. Before you start, you need to check whether the web host enables Let’s Encrypt certificates and that the domain and its www subdomain are pointed to your cPanel account’s IP address. In several instances, if the web host supports Let’s Encrypt, it is also going to install the SSL certificates automatically. If it doesn’t, however, you can follow the steps below to get it done:
1. Access Let’s Encrypt SSL in cPanel
- Scroll down to the “SECURITY” section of your cPanel account.
- Select “Let’s Encrypt SSL.”
2. Issue a new SSL certificate
From the list displayed, select the domain you want to use.
- Under Actions, click “Issue”.
3. Configure SSL Certificate Options
Next, you’ll see a variety of domain options:
- If you select this option, Let’s Encrypt will apply a Wildcard SSL cover to all domains under your domain. Select the DNS-01 validation method if wildcard domains are included.
- Adding cPanel subdomains: Optionally add additional cPanel subdomains. Through these subdomains, you can access cPanel services.
4. Select an SSL Validation Method
Select the validation methods:
- http-01: This method is commonly used for HTTP validation.
- dns-01: Opt for DNS validation if your domain’s nameservers point to cPanel.
5. Issue the Certificate
- After selecting the validation method, click “Issue” to proceed.
6. Installation Process
- The SSL certificate will be installed on your domain automatically.
- The virtual host configuration will update with the new certificate.
- Apache will restart in the background to apply the changes.
Let’s Encrypt is an evolving solution for the website owner that aims to secure the websites in a cost-effective manner. The robust encryption and automatic certificate issuance of Let’s Encrypt makes it a trustworthy choice. No matter whether you manage a blog, a small business website or any other simple website, understanding the answers to important questions like: what is Let’s Encrypt, how does it work, and why is it important to my operations will enhance your online security and build trust with your users.
