Case 08 Zero Trust
Zero Trust Architecture
Rebuilding a growing organization's network on 'never trust, always verify', so a single compromise can't spread.
- Client
- Growing organization
- Engagement
- Zero Trust architecture implementation
- Outcome
- Lateral movement blocked; access limited to what each user needs
Overview
A growing organization was concerned that an attacker who got into its network could move freely between systems. We implemented a Zero Trust architecture built on a simple principle: never trust, always verify. Every user and device must prove who they are, and access is limited to exactly what's needed — sharply reducing the risk of a breach spreading.
Client names and identifying details are withheld for confidentiality.
The business view
The engagement in plain language, for owners, executives and boards.
- The risk
- Once inside the network, an attacker could move freely between systems, and many users had more access than their jobs required.
- What changed
- Every user and device is now verified continuously, access is limited to what each person needs, and the network is segmented so threats can't spread.
- The result
- The risk of a breach spreading is sharply reduced — without slowing down daily work.
The detail for IT and security teams
The challenge
What was at risk
- Once inside, an attacker could move between systems freely.
- Users held more access than their jobs required.
- Little verification of users and devices after the first login.
- Rising risk from remote work and cloud-based systems.
- Protection had to improve without slowing daily work.
Our approach
What we did
- Adopted a 'never trust, always verify' security model.
- Limited access so each user reaches only what they need.
- Added continuous verification of users and their devices.
- Segmented the network to stop threats from spreading.
- Made security seamless so employees stay productive.
