Buys security start-up

In an effort to protect the site from cyber attacks, Facebook purchases PrivateCore, a company that builds security software. Joe Sullivan, Facebook’s chief security officer, says PrivateCore’s technology:

protects servers from persistent malware, unauthorized physical access, and malicious hardware devices.

Based in Palo Alto, CA, the company was started in 2012 by security experts from Google and VMware. PrivateCore CEO Oded Horovitz says the deal gives both companies “a huge opportunity to pursue our joint vision at scale with incredible impact.” Neither company discloses the purchase price.
