New service powered by Incapsula allows organizations to quickly address PCI, protect Web applications and improve Website performance

Redwood Shores, CA – May 9, 2011 – Imperva, the leader in data security, today announced its Imperva Cloud WAF, powered by Incapsula, a cloud-based Web Application Firewall service for small to mid-enterprise businesses that need to effectively achieve PCI compliance, prevent blacklisting, protect against Web application attacks and improve Website performance. To help businesses without dedicated security or IT staff rest assured that their Web applications and data are safe, the Imperva Cloud WAF service includes around-the-clock monitoring, tuning, reporting, and incident response, all managed by Imperva’s world-class team of experienced security professionals. The offering is available today.

“Cloud-based Web Application Firewall technology will be an essential protective measure for small to medium sized businesses. With hackers increasingly targeting small business applications, SMBs will greatly benefit from the low capital investment while ensuring comprehensive protection without dramatic upfront fees or infrastructure changes,” said Lawrence Pingree, Research Director, of Gartner.

According to the Verizon 2011 Data Breach Investigations Report, hackers actively target small to mid-enterprise organizations with standardized, automated attacks because these businesses have fewer protections. These softer targets provide hackers an ongoing stream of valuable data and, as a result, money. According to the Verizon report, between 2010 and 2011, “we saw a virtual explosion of breaches involving smaller organizations.”

“The Imperva Cloud WAF service offers businesses an easy and affordable way to protect critical Web applications and achieve PCI compliance with around-the-clock monitoring from experienced security professionals,” explained Amichai Shulman, Imperva’s CTO. “With Imperva Cloud WAF services, businesses without dedicated security or IT staff will have greater confidence that their applications and data are safe.”

Imperva Cloud WAF helps businesses maintain PCI DSS section 6.6 compliance, which is required for any organization whose Web applications process payment cards. With Imperva Cloud WAF, businesses get continuous protection that does not impact their Web development processes and does not result in burdensome consulting costs.

Imperva Cloud WAF shields Websites and online applications from hackers and other online threats while permitting legitimate traffic. Leveraging Incapsula’s unique technology, Imperva Cloud WAF protects against current and emerging threats including SQL Injection, Cross-site Scripting (XSS), illegal resource access, malicious bots, and other Open Web Application Security Project (OWASP) Top-10 threats. Imperva Cloud WAF also increases Website performance with cloud-based caching that reduces Web page load time, server workload, and Website bandwidth consumption.

Imperva Cloud WAF is provisioned via a simple change to a Website’s DNS setting. It does not require any hardware, software or changes to existing Website code. This easy deployment enables organizations to jumpstart their Web application security initiative in a matter of minutes while maintaining their existing Internet hosting provider and infrastructure.

By leveraging a software-as-a-service (SaaS) delivery model, Imperva Cloud WAF provides businesses with the highest levels of Website security without requiring a large resource investment. Imperva Cloud WAF couples easy deployment and dedicated security expertise with low annual costs to significantly reduce capital expenditures and operational costs.

An Imperva Cloud WAF 1-year subscription at 20Mbps starts at $7,200 and includes Imperva managed security services.
