The IronPort E-Mail Security Appliance e-mail security appliance reduces spam by analyzing inbound messages and calculating a score based on the reputation of the sender. The sender's reputation is based on information from IronPort's SenderBase Network, which samples more than 5 million Web traffic data points daily and sends real-time updates to all IronPort e-mail security appliances. IronPort also examines the complete context of each message. By looking at not just the content of the message but how it is constructed, and factoring in the reputation score, IronPort promises to spot spam accurately. Starts at US$9,000.
