Xirrus Advanced RF Security Manager (RSM)
The Xirrus RSM improves security and minimizes the risk in deploying 802.11
wireless networks. Leveraging an integrated 24/7 threat sensor and hardware-
based encryption/decryption in each Array, RSM secures the wireless network
from multiple types of threats. The result delivers uncompromised overall
network security with superior flexibility and performance.
Wireless networks face a number of potential security threats in the form of rogue
access points, ad-hoc clients, unauthorized clients, wireless-based attacks,
eavesdropping, etc. As “bring your own device” (BYOD) becomes ubiquitous in
enterprise networks, defending against these threats becomes more critical. With
the Array’s threat sensor radio scanning all channels in the 2.4GHz and 5GHz
spectrums, RSM searches for security threats and automatically mitigates them.
High performance encryption/decryption in the enterprise wireless network is a
must. The wireless network needs to support each client using the highest level of
encryption (WPA2 Enterprise/128 bit AES) and without degrading the overall
performance of the network. Xirrus incorporates hardware-based encryption/
decryption into each Array, delivering line-rate encryption at the edge of the
network instead of at a choke point within a centralized controller.
The complete feature set of the RSM package includes:

Wireless IDS/IPS (Intrusion Detection/Prevention System)

Wireless stateful firewall

User group policies

Authenticated guest access gateway
