Cisco snatches up email security firm

Cisco Systems made a move to bolster its security offerings today with the proposed acquisition of security firm IronPort for US$830m in cash and stock. 

IronPort primarily offers email and messaging security software for enterprises. The privately-held firm is based in California and has 408 employees.

Cisco plans to integrate IronPort's products into its Self-Defending Network framework, allowing the security suite to better protect against spam and malware.

The acquisition is expected to close by late April, at the end of the third quarter of Cisco's 2007 fiscal year.

IronPort will remain a separate business unit within the Security Technology Group.
