I put seven UTM products through their paces for reviews published in Information Security magazine. The products, from Juniper Networks SRX, IBM/ISS, Fortinet, Sonicwall, Secure Computing’s Sidewinder, Astaro, and CheckPoint Software, can handle a variety of security tasks including VPN, email filtering and spam protection, intrusion prevention and firewalls. Sonicwall and Fortinet came out on top.

Only a few of these reviews survive, and they have been linked above.
