Search giant Google quietly bought up GreenBorder Technologies earlier
this month in an acquisition that some company watchers have speculated
signals a future security offering.

The deal, which reportedly closed earlier in May, gives Google access to GreenBorder’s virtualization technology,
which allows Internet browsers to run in a sandboxed environment to
prevent malicious code from interacting with a user’s PC. The only
notice of the deal appeared to be a statement on GreenBorder’s support site.
