Choosing a UTM

For any company looking at UTMs, it is essential to define requirements and thoroughly research the market, but going for an established name with a proven record in firewall security is a good way of establishing a shortlist. Bear in mind that there is no legal definition of a UTM and that there are significant variations between UTM appliances. The variations are on price, functionality, performance, scalability and most importantly security.

Not all suppliers provide solutions that are suitable for larger companies. Performance is a key element. Many UTMs aren’t designed for all the functions to work together, so performance can rapidly decline when all functions are switched on.

You may want considerable room for growth or an appliance that is licence upgradeable for both performance and function. You’ll also need a firewall that has deep packet inspection as a minimum, not just stateful inspection.
