Cisco Systems, Inc. announced this morning that it will acquire the privately held email security provider IronPort Systems, Inc.
Cisco will pay $830 million in cash and stock for IronPort, which manufactures messaging security appliances from its headquarters in San Bruno, Calif. IronPort was founded in 2000 and has 408 employees.
IronPort's technology will be incorporated into Cisco's products for threat mitigation, data-leak prevention, security policy control, and network access and control management, according to a statement from Cisco.
The statement said Cisco expects the acquisition will not materially affect its 2007 earnings.
In addition to its email security appliances -- which IronPort literature claims are used by more than 20% of the world's largest companies and eight of the 10 largest Internet service providers -- the company makes Web security devices that are designed to scan file signatures and filter out spyware. Its security management appliances combine email and Web security devices, and provide a management tool through which the products can be monitored, administered and integrated with other security systems.
