Features include: firewall, SSL and IPSec VPN, URL filtering, network antivirus, and antispam.
The ProsSecure UTM50, while a bit pricier than some models in the ProSEcure line, offers far higher anti-virus and VPN throughput, as well as a vastly increased number of concurrent connections (40,000 with the UTM50 vs. 8,000 with the UTM5) for businesses needing those levels.
The increased robustness of the UTM50 should make it a solid consideration for businesses whose networks and Web presence are themselves robust and growing. The $899 price covers all connected devices -- there's no per-seat pricing.
