The US$830 million deal is "a natural extension to
Cisco's security portfolio" as enterprises increasingly grapple with the need to safeguard email and other messaging technology, according to a news release.
"This is a step that Cisco had to take because security is moving away from just being about the network and devices and is becoming focused on securing the data," James Quin, senior research analyst at Toronto-based
Info-Tech Research Group, told SCMagazine.com today.
IronPort's appliance solutions expanded in November when it announced plans to acquire
PostX, maker of email-encryption services.
This is the first security snag for Cisco since it acquired endpoint security firm Meetinghouse in July for almost US$44 million. Two months later,
Microsoft and Cisco announced plans to integrate their network access control architectures.
In November 2005, Cisco scooped up the security intelligence assets of
Cybertrust for US$14 million. The Intellishield Alert Manager provides daily vulnerability updates to customers.
But Quin said the
IronPort acquisition is unique because it represents the changing face of enterprise security.
Quin cited Symantec's recently announced Security 2.0 initiative, focused on rolling out products aimed at identity and reputation protection, and Check Point's acquisition in November of
Protect Data, parent of
Pointsec Mobile Technologies.
"Making sure that data is appropriately protected is the next frontier," he said. "It's where security is going, and Cisco is just being prudent by keeping pace."
In other Cisco news, the company reported Wednesday that its Clean Access solution contains multiple vulnerabilities that can be exploited by attackers to escalate privileges and access sensitive information. In an advisory, the
French Security Incident Response Team rated the flaws "high risk."
