The service, powered by Imperva's cloud-based subsidiary Incapsula, provides a defense against DDoS threats.

Data security solutions specialist Imperva announced the availability of Cloud DDoS Protection, a cloud-based service that is designed to safeguard small to medium-size businesses from distributed denial-of-service (DDoS) attacks. By subscribing to this service, businesses can help protect against the downtime, brand damage and potential lost revenue caused by DDoS attacks, the company said.

The service, powered by Imperva's cloud-based subsidiary Incapsula, provides a defense against all types of DDoS threats, including network-based attacks, like SYN or UDP floods, and application attacks that attempt to overwhelm server resources. In addition, Cloud DDoS Protection scales on-demand to stop multi-gigabit denial-of-service attacks. Customers can provision the service by changing their Website's DNS setting, according to the company.

The Security Operations Center (SOC) granularly tunes policies using collective knowledge about DDoS threats, including new and emerging attack methods and known malicious users. When under an attack, the Imperva SOC monitors application performance to keep protected Websites accessible.

"Hackers frequently tune DDoS attacks, and our service will help enterprises better block one of the main weapons in a hacker's arsenal. This year we've seen a number of significant DDoS attacks that have caused significant down time for Websites," said Amichai Shulman, CTO of Imperva. "The Cloud DDoS service combines scalable DDoS protection that is tuned in real time by a team of DDoS experts with technology powered by Imperva's cloud-based subsidiary Incapsula."

The service also complements the capabilities of the SecureSphere Web Application Firewall. While SecureSphere stops application DDoS attacks, attacks designed to overwhelm organizations' Internet connections are better dealt with before they reach organizations' networks, Shulman said. Cloud DDoS Protection scales on-demand to protect against multi-gigabit attacks—much greater than many enterprises' Internet connections—and to avoid costly over-provisioning of bandwidth.

"When we were under a DDoS attack, our traffic went up 100-fold. Imperva Cloud DDoS Protection stopped the attack and kept our site up and running. Imperva's DDoS Protection service is as cost-effective as it is powerful," explained Mark Widman, a network administrator at Keystone RV.
