Cisco Systems agreed to acquire IronPort Systems, a start-up specializing in messaging security appliances, for approximately $830 million in cash and stock.
IronPort, which is based in San Bruno, California, is best known for its email security platform. The company claims that eight of the ten largest ISPs and nearly 20% of the world’s largest enterprises are using its platforms. The systems provide spam defense, virus defense and content scanning. IronPort also offers a line of web security appliances, which protect the network perimeter against spyware and a wide variety of Web-based threats. These appliances combine multiple layers of Web security technology such as deep application content inspection, a Layer 4 Traffic Monitor, IronPort Web “Reputation Filters” and multiple malware signatures.
“We feel there is enormous potential for enhanced email and message protection solutions to be integrated into the existing Cisco Self-Defending Network framework,” said Richard Palmer, senior vice president of Cisco’s Security Technology Group.
IronPort has 408 employees based primarily in San Bruno, California.
