Security and compliance continue to be top priorities for businesses with a digital presence.

Protecting your digital assets is more important than ever, so an increased focus on security applies not only to software delivery but also to the vital task of testing websites and mobile apps to drive a quality and trusted user experience.


To do this effectively, you require proven and efficient security protocols and a high-performing and scalable infrastructure. Whether running tests on virtual or real device clouds, it's common to require a secure connection to software behind a corporate firewall or in your local environment. And, of course, you want to run these tests quickly and with minimal hassle.


Building upon Sauce Labs’ impressive 13+ years of experience, we are bringing secure testing to the next level. Sauce Connect has always been a foundational element of our platform, providing a crucial layer of connectivity and testing security. As industry standards and practices evolve, so do we. We've taken an innovative approach to secure testing with Sauce Connect 5 that can enhance your testing performance using industry-standard protocols and streamline the developer experience using package-managed installation.
