Browser compatibility is a crucial factor in delivering a positive online experience. Staying updated with the latest browser versions ensures not only compatibility but also access to enhanced security protocols.

#### Note on emSign Cross-Sign Support

The emSign cross-sign provides extended trust for legacy systems such as older browsers, operating systems, and runtimes (e.g., Windows XP, Android 2.3, macOS 10.4, iOS 3.x, early Firefox/IE/Java). This ensures continued compatibility where newer roots may not be present. However, it is recommended to always use modern browsers and updated platforms for optimal security, performance, and compliance with current industry standards.
