The zero trust data pillar is a foundational concept in cybersecurity that operates on the principle of continuous verification and strict access controls for data. Instead of assuming that any entity—inside or outside a network—is trustworthy, it requires constant authorizations and only grants access when strict identity and security standards are met. This pillar ensures that data is protected at every step, from its storage and processing to its transmission. Through encryption, identity verification, and monitoring, zero trust in data helps organizations prevent unauthorized access and minimizes the risk of data breaches, creating a resilient and secure data environment even if other security layers are compromised.
