Google's Google Secure Access Wi-Fi service is an IPSec virtual private network (VPN), and Gmail improves on the average corporate e-mail system with such features as spam blocking and storage capacity, and also does not sign every message with a threat to sue the reader. That is not a reason as yet to get rid of Exchange or look for a new profession, but follow on Gmail versions could be. With Google Secure Access, users download a client that automatically routes all their wireless traffic through an encrypted tunnel to the Googleplex. The service is free, even though it has the power of the VPN. However, Google also gets to sniff Internet connections and track locations. Google does log traffic, but its policy is not to retain cookies from other sites, and Google tries to delete such information as passwords. However, as a way to secure home networks, this seems even odder than the most recent proposal from Intel and Microsoft, which is the transfer of keys through radio frequency identification (RFID) cards, which requires an radio frequency identification (RFID) reader in every 802.11 device. Google is aiming the service primarily at people in Wi-Fi hotspots, including enterprise users, who can choose not to use it. However, two trends become apparent with the advent of Gmail. One is that Web-based ASPs, including Google, can easily match the abilities of enterprise IT software. Another is that Google's real goal in gathering data is to understand you better so that its advertisers are better able to manipulate you into giving them your money.
