Sometimes acquisitions are about immediate returns and responses to requests from major customers, and sometimes acquisitions are more about moving a company towards its vision. Webroot's announced acquisition of Prevx is interesting for its statements about the future direction of endpoint security, and leveraging cloud-based security services.
"Thin on the device, thick in the cloud". The major entry points for attacks are still browsers and e-mail agents -- both services that are delivered through the cloud and that can be kept clean in the cloud. With new attacks being defined approximately every 1.5 seconds, there is no way for individual devices to have the latest attack patterns and to continually scan without performance headaches. The future direction of endpoint security includes utilizing the processing power of shared data centers in the cloud to scrub traffic, and having a thinner presence on the endpoint, perhaps to enforce whitelists and to control USB devices.
