What it is

A security framework that eliminates implicit trust and requires verification for every user, device, and service attempting access, regardless of location.

Core Principles

  • Verify explicitly: Use all available data points for authentication
  • Least privilege access: Limit user and service permissions to minimum required
  • Assume breach: Design for containment and minimize blast radius

Implementation Components

  • Identity and Access Management with multi-factor authentication
  • Network micro-segmentation and policy enforcement
  • Device compliance and endpoint protection
  • Real-time risk assessment and adaptive policies

Benefits

  • Reduced attack surface and lateral movement
  • Improved visibility and audit trails
  • Better compliance posture
  • Support for remote work and cloud adoption

When to use

  • Cloud-first or hybrid infrastructure
  • Regulatory compliance requirements
  • Remote workforce or BYOD environments
  • Legacy perimeter security proving inadequate
