"As Groople has grown, I have seen the volume of e-mail-based attacks skyrocket," said Larsen, the company's manager of IS. "It soon overburdened our e-mail gateway, and I was forced to implement new systems and software to handle the huge increase." Vendors and enterprises alike are faced with a new e-mail threat landscape, where spam is increasingly laced with malware and targeted attacks have become more common. IT pros have a lot to consider-both in terms of technology and best practices-as they deal with the growing e-mail security challenge. How do you take control of e-mail-ruthlessly or humanely?

According to Larsen, Groople grapples with about 1 million e-mails each month, 76 percent of which are either blocked by Trend Micro's Network Reputation Services or quarantined as spam. About 5 percent of spam messages get through to Groople in-boxes, he said. To avoid this messaging traffic overburdening the network, the company went to a load-balanced e-mail gateway environment earlier this year. Larsen said he made sure security was woven into the gateway's fabric. "Our entire e-mail infrastructure is architected in conjunction with our security infrastructure ... to maximize the use of multiple layers of protection," Larsen said. "An attack must make it through several separate layers to get onto a user network. Any company that looks at e-mail as simply a business tool is blind. E-mail is a significant security threat to all businesses and should be addressed aggressively."
