What is Comodo SSL?
Comodo is a trusted brand offering SSL certificates designed to protect your website’s traffic. A Comodo SSL certificate creates a secure, encrypted connection between the visitor’s browser and your server. When sensitive data such as a password, email address or payment information is collected on your site, the SSL certificate encrypts it instantly. As a result, even if malicious actors try to intercept the connection, the data remains completely unreadable and your users’ personal information stays safe.
Comodo SSL is a trusted SSL certificate brand operated today under Sectigo, offering DV, OV, EV and Wildcard SSL certificates for websites and e-commerce businesses.
How Does a Comodo SSL Certificate Work?
SSL (Secure Sockets Layer) technology works with a method called public-key encryption. When a visitor connects to your site, an ‘SSL handshake’ takes place between the browser and the server: the certificate’s validity is verified, a session-specific encryption key is generated, and from that point all data between the two parties is protected with 128/256-bit encryption. The padlock icon and the https:// prefix in the address bar indicate that this secure tunnel is active.
Comodo SSL is fully compatible with banking infrastructures and is seamlessly supported by 99.9% of web browsers. So no matter which device or browser your visitors use, they won’t encounter a ‘Not secure’ warning.
Why Is HTTPS Important?
After 2018, Google began flagging sites without SSL (running only over HTTP) as ‘Not secure’ in the browser and ranking them lower in search results. HTTPS is no longer optional but mandatory. Using an SSL certificate not only ensures data security but also creates a trust signal for Google that contributes to your organic ranking and increases visitors’ confidence to shop on your site.
Who Is Comodo SSL Suitable For?
Comodo SSL certificates are offered at different validation levels for blogs, personal sites, corporate websites, e-commerce sites and advanced web projects.
Is Comodo SSL Reliable?
Yes, it is extremely reliable. Comodo uses 256-bit encryption, the industry’s highest standard, which makes stealing data nearly impossible. It is compatible with all major browsers such as Chrome, Safari and Edge and with mobile devices. It also offers high warranty coverage against a potential certificate vulnerability.
Comodo or Sectigo?
Comodo CA was renamed Sectigo in 2018. So the ‘Comodo SSL’ certificates you buy today are actually issued by Sectigo — the brand heritage, root certificates and chain of trust remain unchanged. Before the rebrand, Comodo was the world’s largest commercial Certificate Authority and issued more than 100 million digital certificates. In short, ‘Comodo’ and ‘Sectigo’ refer to the same trusted infrastructure.
