Do you find yourself leery about using public Wi-Fi networks? You should be. All manner of attacks are possible, especially if the Wi-Fi hardware isn't as up-to-date as it should be.

Comodo has the solution: a VPN service named TrustConnect. There are daily, monthly and annual contracts available. Enterprise customers may have their own VPNs, but when you're on personal business you still need to be secure.

Your communications will be secure at least up to the point of Comodo, at which point they connect back out to the rest of the Internet, probably in the clear (unless, for example, it's an SSL site). So there's still some exposure there, but it's not likely to happen between Comodo and your surfing destination.

Of course, VPNs aren't a cure-all, and a compromised PC connected to a VPN is still compromised, but it can be a powerful tool for protecting assets at both ends of the connection.
