Facebook has acquired cybersecurity firm PrivateCore in the hope of thwarting off security threats against its servers and users.

“I’ve seen how much people care about the security of data they entrust to services like Facebook,” wrote Joe Sullivan, Facebook’s chief security officer, in a Facebook post on Thursday.

“[PrivateCore’s] vCage technology protects servers from persistent malware, unauthorized physical access, and malicious hardware devices, making it safer to run any application in outsourced, hosted or cloud environments,” he added.

Terms of the deal were not announced, but media reports say Palo Alto, Calif.–based PrivateCore received $2.3 million in investment from TEEC Angel Fund and Foundation Capital.

Oded Horovitz, CEO and founder of PrivateCore, expressed his excitement over the acquisition in a statement. “Working together with Facebook, there is a huge opportunity to pursue our joint vision at scale with incredible impact.”

“Over time, Facebook plans to deploy our technology into the Facebook stack to help protect the people who use Facebook,” he added.
