Keep Pace with Growth in Encrypted Traffic

Firebox M400 and M500 firewalls are specifically engineered for midsize and distributed enterprises that are struggling to effectively and affordably secure networks in the face of explosive growth in bandwidth rates, encrypted traffic, video use, and connection speeds.

With an operating system built on the latest generation of processors from Intel, the M400 and M500 have all the power they need to run their security scanning engines in parallel, without causing a bottleneck in performance – while still leaving “head room” to add future engines as security trends evolve.

Network attacks targeting enterprises increasingly use encrypted traffic to bypass standard controls. With the dramatic rise of encrypted traffic, it has become crucial to address threats within those encrypted HTTPS streams – while still maintaining enterprise-grade performance. The WatchGuard Firebox® M400 and M500 appliances are up to 61 percent faster than competing solutions with all layers of WatchGuard’s award-winning defense-in-depth solutions turned on, and up to 149 percent faster performing HTTPS inspection. This ensures IT pros never have to compromise network security for performance. Learn more >
