When you're at work there's probably a firewall between you and the nasty Internet protecting you from all those malicious hackers. ZyXEL introduced this product at CES to help when you're not. This little box does firewalls and more. From their press release:

This easy-to-pack, compact network device is equipped with advanced safety and security features that connect you to the LAN or Internet through any broadband connection. With a powerful SPI Firewall and Network Outbreak Prevention, it behaves as one of the frontline protections for individual PCs from Internet attacks. You can also optionally block Java, Active X and cookies. With the light-weight, compact device, the ZyWALL P1 also provides VPN connection for mobile users to create a private secure hotspot for yourself where ever you go. No extra sophisticated software installation and configuration effort is needed. Once you're connected over VPN, it's just like being attached to the local network.
