E-mail Security in the Cloud: More Secure, Less Expensive: Study

By Calvin Azuri, TMCnet Contributor


Users of cloud-based email security solutions show substantially better results than users of on-premise email security implementations in the critical areas of security, compliance, reliability and cost. This is the conclusion drawn by Aberdeen (News - Alert) Group, a Harte-Hanks Company based on research findings from multiple benchmark studies on email security and security software as a service.

In addition, users of cloud-based email security solutions reported 47 percent fewer incidents of spam and malware compared to companies using on premise email security solutions. Users of cloud-based email security solutions also reported 65 percent fewer audit deficiencies, 50 percent less security-related downtime, and 11 percent lower total cost per end-user per year for email security. 

Aberdeen is highlighting practical examples of cloud-based security services, in light of the current market hype about cloud-based computing. The company has started with email security as the number one use case for security software as a service. Intelligence from the cloud is leveraged by these cloud-based email security solutions, or hybrid solutions.  This can help to ensure that “what happens in the cloud, stays in the cloud”. For example the spam and other email threats are eliminated before they touch the enterprise network. This reduces the risk and the costs are moved from the “not avoided” to the “avoided” category.

Benchmark studies on best practices in email security and security software as a service have been conducted by Aberdeen for all the last three years. The use of cloud-based email security solutions showed the biggest increase over the previous year. According to Derek Brink, vice president and research fellow for IT Security, Aberdeen Group, strong evidence is provided by Aberdeen’s analysis that the jump to email security in the cloud is being led by the top performance companies. Since one model is not likely to prevail as per history and experience, each buyer will select their email security services based on their own unique sense of balance between factors such as security, compliance, total cost, and degree of ownership and control, Brink added.
