In a follow-up article to the Cisco announcement of the acquisition of leading messaging security vendor, IronPort, ChannelWebNews quoted the CEO of Atrion Networking, which works with both Cisco and IronPort, on the ideal timing of the purchase.”œWe’re seeing a number of people that I would call early adopters [replacing their mail security solutions] in the last year and really looking for more manageable, easier-to-use, higher-performance solutions. You’re going to see an explosion of anti-spam/mail security-type solutions being purchased and replaced in the next few years.”In that vein, InfoWorld noted that spam, which had fallen off the enterprise security radar in recent years, has become a hot issue again, as a new breed of”image” spam has found a way around spam filters and filled up enterprise inboxes once again.IronPort’s own statistics from its customer installations show a 100 percent year-over-year increase in spam message volume to 63 billion messages per day in October, 2006. This isn’t really startling news for many of us that endure this stuff piling up in our inboxes or junk boxes in the past few months. It just shows the determination of vendors or hackers everywhere to serve this black market. In terms of the global network security market, Cisco continues to lead with 38 percent share in the third quarter of 2006, according to Synergy Research Group. Check Point Software Technologies Ltd., run from Ramat-Gan, Israel, and Redwood City, California, was second at 9.9 percent, followed by Juniper Networks Inc. at 9.2 percent.
