PrivateCore was a security company that specialized in server data protection. Their main product, vCage, focused on securing server data in use, providing encryption to protect data in the RAM against physical and advanced threats. The company aimed to ensure data confidentiality in cloud and data center environments. In 2014, PrivateCore was acquired by Facebook. As a result, the company's proprietary technology was integrated into Facebook's infrastructure to enhance the security of its servers. Please note that PrivateCore is no longer an active independent entity.
