McAfee acquired Stonesoft for $389 million in May mainly for the Finnish security firm's Evasion malware detection engine, which has been praised for its ability to detect custom malware designed to conceal itself from file inspection technology. NSS Labs gave Stonesoft positive scores in 2013, and it repeated its performance in the latest round of tests: NSS Labs gave it a "Recommended" rating, calling the appliance suitable for enterprise deployments.
Stonesoft said its 3206 appliance is suitable for high-end data centers and large network central sites. It includes deep packet inspection and a virtual engine for suspicious file inspection. McAfee plans to integrate it more deeply into its entire portfolio. In the latest NSS Labs testing, it earned a 32.6 percent, above average security effectiveness score and a total-cost-of-ownership calculation of $23.83 per protected Mbps. NSS Labs testers liked Stonesoft's unified management console as well as its shortcuts and drill-down features. Testing, however, found throughput performance below the vendor-claimed 10 Gbps.
