Here’s why ZTA stands out:

• Least Privilege Access: Only necessary rights are granted to users and devices. If a breach
does occur, it is limited in scope.
• Continuous Verification: It is not a static process of trusting. It happens in real time using
behavior analysis, device status, and others.
• Micro-Segmentation: The networks are segmented into separate compartments that prevent the
attacker from moving freely throughout the network.
• Encryption Everywhere: The data is encrypted in the rest, in transit and in use – quantum or
not, it is very difficult to crack.
• Comprehensive Monitoring: Real-time logging and analytics to identify anomalies before they
become a crisis.

For instance, Google’s BeyondCorp initiative, a real ZTA implementation, migrated security from network
perimeter to device and user verification and successfully adapted to a cloud-first environment. It is not
just a reduction of the attack surface; it is the creation of a quantum-ready fortress.
