Zero Trust rests on pillars that you must implement together:
Verify explicitly. Authenticate and authorize based on all available data points: identity, location, device health, service or workload, data classification, and anomalies.
Use least privilege access. Limit user access with just-in-time and just-enough-access (JIT/JEA). Risk-based adaptive policies and data protection help contain breaches.
Assume breach. Minimize blast radius through segmentation. Verify end-to-end encryption. Use analytics to detect threats and improve defenses.
