The social network is buying PrivateCore, a cybersecurity firm founded in 2012. It develops software to validate and secure server data — essentially making sure that the photos and messages you post to your social media account stay secure from prying eyes.

“I’ve seen how much people care about the security of data they entrust to services like Facebook,” Joe Sullivan, Facebook’s chief security officer, said in a post Thursday. “PrivateCore’s technology and expertise will help support Facebook’s mission to help make the world more open and connected, in a secure and trusted way.”

Facebook will integrate PrivateCore’s vCore technology into its server stack. It will protect servers from persistent malware, unauthorized physical access and malicious hardware devices. The new protections will help make cloud-based services more secure.

Terms of the deal weren’t disclosed. Palo Alto, Calif.-based PrivateCore was supported by $2.3 million in seed funding from TEEC Angel Fund and Foundation Capital in 2012, according to Crunchbase.

“Working together with Facebook, there is a huge opportunity to pursue our joint vision at scale with incredible impact,” Oded Horovitz, CEO of PrivateCore, said on his company’s website.
