For automated, real-time signature updates, Cisco IronPort solutions can harness the Cisco IronPort SenderBase® Network, which provides an unprecedented real-time view into security threats from around the world. SenderBase data powers Cisco IronPort Virus Outbreak Filters, a preventive security service that protects enterprises from viruses well before antivirus vendors publish virus signatures. The SenderBase application examines the broadest set of data in the industry, currently examining more than 40 different parameters about web traffic. This data is derived from a highly diverse group of more than 100,000 organizations, including the largest networks in the world, which contribute information to the SenderBase application in five billion messages per day.
