Zyxel USG Flex 100 Review

Small businesses face three major challenges because of advances in how people work and collaborate. Increasingly, small businesses are required to provide Wi-Fi to smart devices due to the BYOD trend. It is not only important for small businesses to be able to control, prioritize, and block various applications to stay productive, but these applications can also open up new Web attacks. Small businesses with limited IT resources face a real problem as threats evolve and challenges diversify.

ZyXEL’s new USG Performance Series is an all-in-one Next-Generation Firewall (NGFW) designed specifically for small businesses to meet the security demands of BYOD, malware protection, and application regulation. With the included wireless access points (USG40W and USG60W) and WLAN controller, users can set up instant hotspots and scale their WLANs in the future.

UTM features and application intelligence technology provide deep and extensive protection while giving businesses control over Web application usage. It provides easy, centralized management and lower total cost of ownership (TCO) with an all-in-one design.

Small businesses no longer have to worry about threats, spam, or social networking sites affecting productivity.

Access to Wi-Fi wherever you need it: The ZyXEL USG Performance Series addresses the trend of BYOD by providing Wi-Fi wherever it is needed. A single-radio AP and a dual-radio AP are built into the USG40W and USG60W to provide Wi-Fi for small offices right out of the box. In addition to providing Wi-Fi in multiple areas, such as reception areas and meeting rooms, the USG Performance Series has an integrated WLAN controller.
