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.
