Browser Ubiquity

Browser ubiquity describes how widely an SSL Certificate is trusted across web browsers, operating systems, and devices without any warning. It depends on the roots of the Certificate Authority (CA) being present in the root stores that browsers and devices use to decide which SSL Certificates to trust.

When a Certificate Authority (CA) root is present in those stores, an SSL Certificate that chains back to it is trusted automatically. When the root is missing, the browser cannot verify the SSL Certificate and shows a security warning instead.

Why Browser Ubiquity Matters

Many Certificate Authorities claim high ubiquity, but the figure only matters if the root is actually present in the browsers and devices your visitors use. A newer or smaller Certificate Authority (CA) may not have its roots in every root store yet, which is most often a problem on older browsers and devices that no longer receive updates.

A visitor who meets a security warning is likely to leave, which affects trust in the site and its reputation. High ubiquity avoids that by keeping the SSL Certificate recognized wherever your visitors are.

Ubiquity of Trustico® SSL Certificates

Every SSL Certificate offered by Trustico® is issued by an established Certificate Authority (CA) whose roots have been distributed and trusted for many years, across both current and older browsers. This gives compatibility with around 99.9% of browsers, operating systems, and devices.

Because the roots are long-established, an SSL Certificate stays trusted as new browser versions are released, without the gaps that can appear when a newer root has not yet been added everywhere. Learn About the Sectigo® Certificate Authority 🔗
