Security experts are recommending businesses consider detection, containment and analysis capabilities when it comes to attacks. Put simply, prevention isn't working. For that reason, Milpitas, Calif.-based FireEye has been gaining the attention of businesses because its platform no longer relies on signatures to detect attacks, according to Gartner. The virtual machine-based security platform sits inline and tests suspicious files in a virtual sandbox. Additionally, Cupertino, Calif.-based Taasera sells a virtual appliance that looks for early behavioral evidence of malware. Some network appliance makers are making advances as well. Finnish firewall maker Stonesoft, recently acquired by McAfee, uses a detection engine that looks for malware using anti-detection techniques.
