About PrivateCore
At a glance
PrivateCore is a cybersecurity company specializing in Data Protection, founded in 2011 and headquartered in Palo Alto, United States. It has raised $2.25M in total funding, employs about 4 people, and was acquired by Meta in 2014.
PrivateCore was a venture-backed startup founded in 2012 by security veterans from VMware and Google, headquartered in Palo Alto, California. The company developed server security software focused on protecting data in use — specifically targeting threats that exploit physical server access and memory vulnerabilities. Their primary product, vCage, was designed to secure x86 servers through three core mechanisms: software-based server attestation, full-memory encryption, and operating system hardening. Together, these capabilities formed a trusted computing foundation for physical and virtualized server environments. Server attestation, as addressed by PrivateCore, refers to the process of verifying the integrity of a server's software stack before it is trusted to process sensitive data. Full-memory encryption protects data residing in RAM from physical memory attacks — a class of threats where an attacker with physical access to a server can extract sensitive data directly from memory chips or via hardware interfaces. OS hardening reduces the attack surface of the underlying operating system to limit exploitation vectors. PrivateCore's solutions were aimed at organizations concerned with insider threats, data center physical security, and the integrity of servers handling sensitive workloads, particularly in cloud and hosted environments. The company addressed side-channel attacks as part of its security research and product scope. In 2014, PrivateCore was acquired by Facebook (now Meta), with the stated goal of applying their technology to make global network connections more secure.
