Available as an appliance or as a service IronPort Anti-Spam™ Filters combine a real-time email traffic threat assessment and identify suspicious email senders and best-of-breed conventional techniques with IronPort’s breakthroughcontext-sensitive detection technology, to eliminate the broadest range of known and emerging email threats.

The IronPort Reputation Filtering System was the first in the industry and remains the most sophisticated. It will block over 80 percent of incoming mail at the connection level, saving you bandwidth (the message is never accepted)and system resources. CPU intensive spam and virus filters are only used when needed, and rate limiting is a very effective defense against “hit and run” spam attacks or denial of service attacks. In practice we’ve seen customers with up to 95% of email being spam and all it effectively blocked by the Ironport.

By reducing the downtime associated with spam, viruses and a wide variety of other threats. It is the advanced technology within the IronPort appliance that leads to the highest levels of security in the world. IronPort’s email security appliances support and protect your email systems— not only from today’s threats, and in the future.
