The firewall controls the door to your computer. Because you tell ZoneAlarm how you use your computer, the firewall only allows traffic that you understand and initiate. With Stealth Mode enabled, your computer becomes invisible to the Internet and potential intruders. If you can't be seen, you can't be hacked. ZoneAlarm's firewall provides the ultimate intrusion security for your personal computer.
Application Control lets you decide which applications can and cannot use the Internet. ZoneAlarm monitors all activity on your computer and alerts you when a new application attempts to access the Internet. Application Control ensures that rogue applications like Spyware cannot send your valuable data to criminals and vandals.
The Internet Lock blocks Internet traffic while your computer is unattended or while you are not using the Internet. The Internet Lock can engage automatically with your computer's screen saver or after a set period of inactivity. With the Internet Lock you have absolute control over your always-on connection.
Security Levels make ZoneAlarm easy to set up. In contrast to other security solutions, ZoneAlarm does not require you to learn about ports, protocols and hierarchical rules. ZoneAlarm comes configured to deliver out-of the-box safety and security. Security Levels automatically configure the Firewall and eliminate the risk of improper configuration common to other products. With ZoneAlarm's Security Levels, you get peace of mind, not confusion.
Always-on connections provide the fastest way of sharing important data with people you trust. Zones allow you to grant that privilege to your friends and associates and deny it to everyone else. Through the two zones - Local and Internet - users can easily share their important files on the local network or across the world while keeping them safe from access by strangers.
