Dasient Introduces First Web Anti-Malware Service.

Addresses Growing Need for Protection From New Web-Based Attacks

PALO ALTO, Calif. -- Dasient today introduced the industry's first service to protect companies against a fast-growing class of web-based attacks that compromise legitimate websites and then use them to spread malware to the sites' visitors. Dasient's new Web Anti-Malware (WAM) service continually monitors websites, diagnoses any infections, and helps businesses address the infections, before the sites suffer significant losses in traffic, revenue, and reputation.

"In the last two years, we've seen a fundamental shift in the way malware is spread," said Dasient co-founder Dr. Neil Daswani. "Hackers are using highly automated and mutable attacks to turn websites into delivery vehicles for malicious software. This is a web problem at its core, and it requires a solution that can function at web speed and web scale. That's exactly what we had in mind when we designed the Dasient WAM service."

Sharp Increase in Malware-Infected Webpages

Each day, thousands of legitimate websites are infected with malicious code, often without their knowledge. The speed, scale, and complexity of these attacks makes it extremely difficult for website owners to identify and fix the resulting infections, and in some cases to even know they've occurred.

The most immediate result of web malware infection is blacklisting by search engines like Google and Yahoo; browsers like Internet Explorer, Firefox, and Chrome; and desktop anti-virus providers like Norton and McAfee. When blacklisted, a website's visitors are redirected to a warning that the site they're about to visit might be dangerous. In many cases, being blacklisted causes a sharp drop in traffic to the site, depriving the site owner of advertising or e-commerce revenue, damaging the site's brand, and spurring additional support costs.

Dasient Identifies and Contains Malware That Can Infect Site Visitors

Today Dasient is announcing the following updates to its patent-pending Web Anti-Malware service, which has been in alpha testing with thousands of websites since early this year:

* Free Blacklist Monitoring: Regularly monitors blacklists from search engines, browsers, and desktop anti-virus companies and provides customers with instant alerts if they've been flagged by those providers. The WAM Blacklist Monitoring service is now in public beta, and is available for free to direct customers and web hosting providers.

* Premium Monitoring and Diagnosis: Continuously monitors customer websites for malicious code that can be distributed by web applications, user-generated content, third-party widgets, advertisements, and other vulnerable site elements. When an infection is identified, customers are notified and provided with detailed diagnostic information, including all malicious source code and infected URLs. The WAM Premium Monitoring service is now in public beta, and is available on a subscription basis to direct customers and web hosting providers.

* Quarantining: Used in conjunction with the Premium Monitoring service, Dasient's quarantining technology automatically contains infections as soon as they're diagnosed, serving the webpages in question but not the malicious code. Quarantining prevents the site from spreading malware broadly to its visitors and keeps it from being flagged by blacklist providers. The WAM Quarantining service is now in private beta, and direct customers and web hosting providers can sign up to join the beta on the Dasient site.

The Dasient WAM monitoring and diagnostic services are built on a set of behavioral analysis technologies that continually crawl customer sites and the web, identifying new web-based malware infections. The monitoring and diagnostic tools are provided to customers as a web service, and the quarantining technology is made available as a web server module that can be installed by customers or web hosting providers.
