The Zero Trust (ZT) architecture is a modern concept shaping cybersecurity in the public and private sectors. The growing use of SaaS applications, migration to cloud-based architecture, a rising number of remote employees, and bring-your-own-device (BYOD) have rendered perimeter-based security obsolete. The concept of a network perimeter where those outside of the enterprise's control are malicious and insiders are trustworthy — is no longer a viable approach to cybersecurity.
