Zone Labs Announces the New Standard for Protecting PCs from Hackers and Spyware -- ZoneAlarm Pro 4.0

Latest Version of World's Leading Internet Security Product Combines New Levels of Power, Control and Ease of Use

San Francisco, CA, RSA Conference 2003, Booth #1009 - April 14, 2003 - Zone Labs Inc., a leading creator of endpoint security solutions, today announced ZoneAlarm® Pro 4.0, a new version of the company's award-winning Internet security product. Available next month, ZoneAlarm Pro 4.0 includes powerful new capabilities that can be tailored to every user's skill level in order to protect users' PCs as well as their confidential, personally-identifiable information. Along with significantly enhanced security and privacy features, ZoneAlarm Pro includes new, stronger Internet security measures, including updated anti-hacker and anti-spyware safeguards to combat the latest vulnerabilities and exploits. In addition, ZoneAlarm Pro 4.0 includes Hacker ID™, which gives members of the Zone Labs community the ability to safely track attacks on their PCs and report offenders to the appropriate ISP, thereby helping to make the Internet a safer place for all.

In keeping with Zone Labs' philosophy that powerful security must be easy to use, ZoneAlarm Pro 4.0 further enhances overall ease of use so that even the novice user's PC receives the utmost in 'out of the box' protection. In addition, telecommuters and mobile workers will find it easier to connect to their enterprise networks safely while working remotely since ZoneAlarm Pro 4.0 can now automatically detect and configure VPN (Virtual Private Network) connections. For the expert user, ZoneAlarm Pro 4.0 features new firewall rules to provide precision control over a variety of firewall settings.

"The ongoing cat and mouse game between security providers and hackers requires sophisticated security measures that are accessible to all levels of users - from the novice to the experienced expert," said Frederick Felman, vice president of marketing, Zone Labs. "Every release of ZoneAlarm Pro raises the ante in powerful, proactive protection and with ZoneAlarm Pro 4.0, we are placing a new standard in powerful security within the grasp of every user, whether those users want 'set and forget' security or an arsenal of expert features for complete customization."

The most recent statistics about the growing dangers from identity theft over the Internet illustrate how all Internet users need the powerful protection of ZoneAlarm Pro. The U.S. Federal Trade Commission reported 86,168 instances of identity theft during 2001. In 2002, the Federal Trade Commission reported that consumers attributed more than $343 million to cases of identity theft and fraud.

New and Improved Features in ZoneAlarm Pro 4.0
Key new feature, benefits and improvements in ZoneAlarm Pro 4.0 include:

Outbound MailSafe - monitors outgoing e-mail for activity that could indicate virus infestation and, if found, halts e-mail transmission. Outbound MailSafe prevents users from inadvertently sending virus-infected e-mail to others, providing critical, last-ditch protection for common socially-engineered viruses.

Hacker ID - lets users identify potential hackers and snoops, allowing users to track these offenders and safely take appropriate action. With Hacker ID, users can identify and report serious offenders to ISPs for action. Hacker ID helps the large ZoneAlarm Pro community keep the Internet safer and more secure for all users by making it more difficult for prolific hackers to ply their craft. Hacker ID functions with ZoneAlarm Pro's existing AlertAdvisorsm Service which helps users make informed decisions about the security-related events that are occurring on their PCs in real-time.

Cache Cleaner - clears the PC's hard disk and browser caches to protect the privacy of the user's surfing habits and to free up valuable disk space. CacheCleaner consists of two components that perform at the user's discretion and, to save time and effort for busy users, can be scheduled to operate automatically. The Hard Drive Cleaner removes all temporary files, search history, recycle bin files and other file clutter from the PC, while the Browser Cleaner purges browser-related files, including browser cache, URL history, cookies and page cache. CacheCleaner prevents invasions of privacy by cookie-snooping web sites and is especially useful for users who share a computer.

Expert Firewall Controls - allow fine-tuning of traditional firewall rules, including options to control port, protocol, application, and time of day. The expert firewall controls in ZoneAlarm Pro 4.0 provide highly precise, granular command of firewall settings to advanced users, developers, and security experts.

Increased Hacker-Proofing - blocks hackers from cracking the firewall and then compromising the security of the PC. These sophisticated measures further strengthen ZoneAlarm Pro 4.0 from some of the newest and most dangerous hacker techniques that can stop competitive security products from functioning properly.

Automatic VPN Configuration - automatically optimizes security for a user's VPN session, freeing users from having to tinker with the special configuration issues of VPNs. This new feature is geared to the growing numbers of remote and mobile workers such as road warriors, telecommuters and occasional home users who connect to corporate networks.

Stronger, More Efficient Privacy Features - optimize ad-blocking, cookie control, and protection against third-party spying, resulting in a cleaner interface and faster performance. The improved privacy features in ZoneAlarm Pro 4.0 efficiently block spy-sites and eliminate pop-up ads while users surf, making web-browsing faster and safer.
