PHILADELPHIA, April 25, 2008 — ACE USA, the U.S.-based retail operating division of the ACE Group of Companies, announces the launch of eRisk Hub™, a web-based loss prevention resource designed to help policyholders manage their cyber risk. The eRisk Hub portal is provided to all ACE policyholders who purchase privacy and network security coverage under the ACE Privacy Protection^®, ACE DigiTech^® and ACE Digital DNA^® product lines.

The eRisk Hub provides triage support through its Incident HELP Hotline staffed by security experts who understand the potentially catastrophic impact of privacy and network related exposures. These experts use that knowledge to help companies deal with post-breach regulatory, reporting and crisis management issues. The eRisk Hub also helps policyholders keep abreast of best practices and regulatory guidelines and prepare detailed, comprehensive response plans. Founded and managed by NetDiligence^®, a leading cybersecurity and e-risk assessment services company, eRisk Hub features news, and informative content from leading cyber risk experts (including risk management, computer forensics, forensics accounting, crisis communications, legal and other specialists.)

“We are delighted to announce the launch of eRisk Hub. This informative, value-added resource gives our policyholders instant access to the most current and comprehensive information, expertise and specialized resources that can help them manage their network and data risks on the front end, and to respond quickly and appropriately should they experience a hack or data breach,” said Toby Merrill, Assistant Vice President, ACE Professional Risk.

According to Mr. Merrill, increasingly sophisticated network attacks and data thefts are on the rise, and no organization is immune. Even those with strong security and privacy controls in place can be victimized by internal fraud, data theft, and the accidental loss of sensitive information. The resources of the eRisk Hub serve as a safety net that complements and extends network risk management, incident response and business continuity plans and programs. Organizations can use eRisk Hub to locate qualified external resources with highly-specialized expertise to help manage the post-exposure fallout, develop breach recovery plans, as well as stay on top of legal and regulatory changes, emerging and changing cyber threats, and recommended security and privacy practices.

“As a market leader in privacy and network liability, ACE understands that when an incident occurs, most policyholders need immediate and specialized expertise. Privacy and network exposures can be very complex and must be addressed quickly and appropriately. We want policyholders to use the eRisk Hub as their “one stop shop” for the vital information and expert resources that can help minimize their network risks and access the necessary tools to react appropriately in the event of an incident. The eRisk Hub is an essential complement to our existing privacy and network liability products,” commented Mr. Merrill.

Key eRisk Hub features include:

• Incident HELP Hotline: Staffed by security experts who provide immediate triage assistance in the event of a breach.
• eRisk Resources Directory: Comprehensive directory of external resources with deep expertise in pre- and post-breach disciplines.
• News Center: Resource for current privacy and network security news, security and compliance blogs, risk management events, and helpful industry links.
• Learning Center: Best-practice articles and white papers written by leading technical and legal experts on compliance, network security, privacy and breach recovery.
