This Comparative Report provides the enterprise with Total Cost of Ownership (TCO) and TCO per Protected Mbps metrics from this group test. While TCO is important, the TCO per Protected Mbps metric goes even further by factoring NSS-Tested Throughput and Security Effectiveness into TCO. This more accurately represents the true cost of owning a security network product. Products were subjected to thorough testing at the NSS facility in Austin, Texas, based on the NSS Labs Next Generation Intrusion Prevention System Test Methodology v5.0.
