TrustFour is a cybersecurity company focused on securing workload interactions through a zero-trust approach to Workload Attack Surfaces and Non-Human Identities (NHI). The company leverages Transport Layer Security (TLS) combined with an authorization control system to protect machine-to-machine and workload-to-workload communications. Their core solution is designed to be straightforward to implement, using TLS as the foundational security protocol to authenticate and authorize workload interactions. The platform addresses the challenge of securing non-human identities — such as service accounts, APIs, and automated processes — that communicate across modern infrastructure environments. Key focus areas include: - Workload Attack Surface protection - Non-Human Identity (NHI) security - TLS compliance and enforcement - Zero-trust based authorization controls for workload communications TrustFour targets organizations seeking to reduce risk from machine-to-machine communication channels, which are often underprotected compared to human user access. The company is headquartered in San Diego, California, with additional offices in Austin, Texas, and Bangalore, India. The company was co-founded by Robert Levine (CEO), Pugal Panneerselvam (VP Engineering), and Jim Curtin (COO). TrustFour has received backing from EvoNexus and Go Ahead Ventures, and maintains an advisory board with expertise spanning identity management, cloud architecture, military cybersecurity, banking regulation, and quantum computing.
