Choosing the right Certificate Authority (CA) is an important step when securing your website with an SSL certificate. A CA is a trusted entity that issues digital certificates, verifying the legitimacy of websites and enabling encrypted connections. While all CAs provide the same core functionality—issuing SSL certificates—they differ in terms of trust level, pricing, support, warranty, and additional features.
In this blog post, we'll compare some of the most popular Certificate Authorities (CAs) to help you decide which one is the best fit for your website. We’ll look at trusted CAs such as Comodo, DigiCert, GlobalSign, Let’s Encrypt, and GoDaddy, examining their key features and differences.
What is a Certificate Authority (CA)?
A Certificate Authority is a trusted organization that issues SSL certificates to websites after verifying their identity. When a user visits a website secured by an SSL certificate, their browser trusts that the connection is secure because the SSL certificate was issued by a reputable CA. CAs play a crucial role in ensuring trust and security across the internet.
