### AI overview

This article explains Zero Trust Architecture as a security model that assumes the network may already be compromised. It contrasts Zero Trust with perimeter security and describes explicit verification, contextual authorization, least privilege, encryption, segmentation, and continuous monitoring. It also distinguishes the broader ZTA model from Zero Trust Network Access (ZTNA).

### Source excerpt

Zero Trust starts from the assumption that the network is already compromised, so every request is authenticated, authorised, and encrypted regardless of where it originates. It rests on explicit verification, least privilege, micro-segmentation, continuous monitoring, and encryption everywhere. It is an architectural direction, not a product you buy.

### AI overview

This article compares VPN-based remote access with Zero Trust Network Access for remote working security. It describes VPN benefits and limitations, including broad network access, weaker granularity, slower connections as usage grows, and management complexity, then introduces zero trust as an alternative and outlines the transition to a zero-trust architecture.

### Source excerpt

This article will explore how zero trust access is a better alternative than a VPN for remote working.
