Cisco Systems and Trend Micro have reaffirmed their relationship by signing an agreement to extend Trend Micro security services incorporated into Cisco's network infrastructure products.

The agreement advances the two companies' relationship, which started in 2004 when they began plans to incorporate Trend Micro's content security services into Cisco's Adaptive Security Appliance family. Under this agreement, the companies now will work closely on integrating additional content security services into Cisco's routing offerings.

In addition, as part of the two companies' ongoing collaboration, Trend Micro has delivered Trend Micro's Damage Cleanup Services for Cisco's mitigation, analysis and response system to further the vision of Cisco's Self-Defending Network.

"Our work with Trend Micro will continue to support our Self-Defending Network vision and enhances our ability to provide end-to-end security that combines network, application, and content protection," said Tom Russell, senior director of product management for Cisco's Security Technology Group. "We are happy to continue collaborating with Trend Micro."

"Trend Micro is very pleased with the momentum we are building with Cisco Systems. Through the strengthening of our relationship with Cisco, we are continuing to further the delivery of security within the network infrastructure," said Punit Minocha, vice president of business development for Trend Micro.
