Crowdsourcing has proven successful for organizations or individuals seeking assistance on a project from a larger group of people. Some technology vendors are applying it to security. Santa Clara, Calif.-based Palo Alto Networks has been gaining attention with the crowdsourcing capabilities associated with its network security appliances. The company's Wildfire platform uses a cloud-based malware analysis environment that shares threat information with all subscribers to the service. Columbia, Md.-based Sourcefire sells its FireAmp appliance line with crowdsourcing antimalware capabilities.
