Unified threat management (UTM) is an approach to information security where a single hardware or software installation provides multiple security functions. This contrasts with the traditional method of having point solutions for each security function. UTM simplifies information-security management by providing a single management and reporting point for the security administrator rather than managing multiple products from different vendors.
UTM appliances have quickly gained in popularity, partly because the all-in-one approach simplifies installation, configuration, and maintenance. Such a setup saves time, money and people when compared to the management of multiple security systems.
