Always-On, Cloud-Based Service Detects All Types of DDoS Attacks, Preventing Costly Website Interruptions While Speeding the Delivery of Content to Researchers Worldwide

REDWOOD SHORES, Calif., Dec. 15, 2015 (GLOBE NEWSWIRE) — Imperva, Inc. (NYSE:IMPV), committed to protecting business-critical data and applications in the cloud and on-premises, today announced that Karger Publishers, a global medical and scientific publishing company, has selected Imperva Incapsula. The company will use the Incapsula service to ensure that its website, containing approximately 100 new scientific journals per year and a vast e-book archive, is accessible at all times by researchers at leading hospitals, research centers and universities all over the world.

In June 2015, the Karger website was the target of a massive distributed-denial-of-service (DDoS) attack that was controlled by a botnet with zombie clients all over the world. Shaken by the attack, the company evaluated several solutions and ultimately chose Imperva Incapsula because of its ability to detect, filter and control HTTPS traffic, the robustness of the cloud access security broker (CASB) offering and the speed at which Imperva was able to implement.

“We had an internal Intrusion Prevention System (IPS), but it was not able to detect the DDoS attacks we were experiencing,” said Daniel Hangartner, IT Project Manager at Karger Publishers. “We found a 70 percent increase in traffic, most of which was log files, which indicated a paid HTTPS attack.”

Marc Gaffan, General Manager for the Imperva Incapsula service, noted: “Karger was keen on getting the system up and running quickly while being able to tackle the root of the problem—filtering and controlling HTTPS traffic. Through a streamlined implementation, we were able to mitigate the attack and get defenses in place quickly.”

Once the Imperva Incapsula web application firewall (WAF) and content delivery network (CDN) were deployed in front of the Karger site, it resulted in an immediate drop in unwanted traffic. In addition, site performance has since improved and it has not been attacked again. The Imperva Incapsula Content Delivery Network (CDN) offers an added benefit of faster application delivery and enhanced user experience for researchers by enabling the Karger website to serve up dynamic content for paid subscribers without any cached content.

Imperva Incapsula is a cloud-based application delivery service that makes websites safer, faster and more reliable. Using Incapsula, organizations of any size can protect their businesses with enterprise-grade web application security, DDoS mitigation, performance optimization and load balancing.
