Open source is the most effective method for developing secure and reliable software on the planet. It is inherently secure by design because it relies on a transparent exchange of information, technology, and collaborative development. Because Guardian Digital is a pioneer in open-source software, enterprise email solutions, and cyber security, it is committed to open-source development and innovation. Our enterprise email security solutions are more flexible and more effective as a result.

Real-time Enterprise Cloud Email Solutions

Because Guardian Digital’s solutions are built on our advanced cloud platform that combines open-source technologies with the security expertise of our engineers, the result is a system that updates rapidly and learns over time to protect your business email from advanced and persistent threats. Our worldwide network of systems works cohesively to collect billions of data points using big data analytics, our own algorithms, and machine learning to update systems with the latest real-time information. This reduces the exposure to zero-day threats as well as the largest spam campaigns around the globe.  

Open-source development also allows Guardian Digital to customize your email security platform to your specific needs. Better yet, it allows us to do this without jeopardizing your bottom line.

We are proud to be a citizen of the open-source community. We know, from decades of open-source development expertise, that using open-source methodology for securing digital information creates a more robust and secure platform precisely because its core components have been subjected to rigorous peer review for decades.

Since its inception in 1999, Guardian Digital has recognized that the open-source model provides the best approach to the problem of maintaining security in the relentlessly dynamic environment of the internet.

The ideals that the open-source community follows and hold dear — community engagement, openness, collaboration — are also the ideals that Guardian Digital holds among its main tenets. It’s a reflection of an environment that is highly collaborative, and where the best solution always comes out ahead. In this environment — where flexibility, choice, and an affordable costs are built into the process — Guardian Digital customers win.
