Forrester evaluated leading ITAM vendors across 43 criteria and found that HP and CA lead overall with industrial and proven solutions. BMC Software also has a leading solution and is refocusing its sales force to leverage this leadership. Altiris is a proven leader in the medium-size market, with a well-received portfolio approach. USU and PS'SOFT are leading European solution providers with enterprise and mid-market success. Provance Technologies sells primarily to service providers that offer ITAM as a service. MRO Software is a leading facilities and ITAM vendor, with less focus on IT aspects than others. Centennial Software and REALTECH are two vendors that address specific customer segments, but with less ITAM functionality.
