Unified threat management devices provide small and midsize businesses with multiple network security functions in a single appliance. SMB buyers should carefully evaluate UTMs' performance when numerous security functions are enabled, and UTMs' ability to handle new SMB practices. Gartner defines the unified threat management (UTM) market as multifunction network security products used by small or midsize businesses (SMBs). UTM products must continually add new functions, and therefore encompass the feature set of many other network security solutions, including next-generation firewall, intrusion prevention systems (IPSs), secure Web gateway and secure email gateway. While consolidation comes with compromises in performance and capability, these are compromises that many SMBs are willing to accept.
