About this guide

Zero Trust inverts the old rule. Not connect then authenticate — authenticate, then connect.

Where the idea came from, what ZTNA adds, and the five steps for an organisation that has not started. Written for companies with a few hundred to several thousand users, where this is usually assumed to be out of reach.

Inside
01Define your protect surfaces — start small, and not with the ERP system
02Map the transaction flows — users to applications, actions and data
03Architect from the inside out — move controls closer to the user, reduce DMZs, log everything
04Formulate the policy — context and conditional access, IDaaS, adaptive MFA, least privilege everywhere
05Monitor and maintain — find the edge cases through logging before you change the process
06Plus a short history, from Black Cloud in 2007 to the NCSC’s 2019 recommendation
