ES520 Secure Wireless Bridge


The Fortress ES520 allows organizations to quickly establish networking and communications in environments with no available infrastructure. With a dual radio design that allows for simultaneous wireless backhaul and wireless access, the ES520 offers high assurance FIPS 140-2 validated security as well as industry leading radio range. Combining these services along with an eight port Ethernet switch in a small and rugged form factor enables the ES520 to provide on-demand secure voice, video and data communications. Whether for rapidly deployable kits, vehicle area networks, emergency response or situational awareness, the Fortress ES520 is the proven choice to meet the most challenging deployable networking requirements.

Fortress Secure Wireless Bridges are all-in-one network access devices with built-in security. The ES520 is ideally suited to work as a self-contained network combining the functions of a wireless access point, Ethernet switch, and security gateway in a form factor engineered specifically for harsh outdoor environments.
