ZERO TRUST
SECURITY
LONDON
Coreitech implements Zero Trust security architecture for London businesses — "never trust, always verify" applied to every user, device, and application. Built on Microsoft 365 native tools, aligned with NCSC guidance.
Zero Trust security
pillars we implement
Identity Verification
Multi-factor authentication, conditional access policies, and Entra ID configuration — every user verified before accessing company resources.
Device Health
Intune MDM ensures only compliant, patched devices access your network. Non-compliant devices are blocked automatically.
Network Segmentation
Micro-segmentation prevents lateral movement. Compromised devices cannot reach other systems on the same network.
Application Access
Conditional access restricts app access based on user, device, location and risk level — not just username and password.
Data Protection
Microsoft Purview sensitivity labels, DLP policies, and encryption ensure sensitive data stays protected regardless of where it travels.
Least Privilege Access
Users receive only the permissions they need. Privileged Identity Management (PIM) enforces just-in-time access for admin accounts.
Zero Trust security —
questions answered
Q.What is Zero Trust security?
Zero Trust is a security framework based on the principle "never trust, always verify." Unlike traditional perimeter security that trusts everything inside the network, Zero Trust continuously verifies every user, device, and application — regardless of whether they are inside or outside the corporate network. It is particularly important for modern businesses with remote workers, cloud services, and BYOD devices.
Q.Does my London SME need Zero Trust security?
Yes — especially if your team works remotely, uses cloud services like Microsoft 365, or accesses company data from personal devices. Traditional perimeter firewalls alone are no longer sufficient. Zero Trust is recommended by the NCSC (National Cyber Security Centre) and is the foundation of Cyber Essentials Plus and ISO 27001 compliance. Coreitech implements Zero Trust using Microsoft's native tools included in Business Premium.
Q.What Microsoft tools are used for Zero Trust?
Microsoft's Zero Trust architecture uses: Microsoft Entra ID (identity and conditional access), Microsoft Intune (device compliance and MDM), Microsoft Defender for Business (endpoint protection and EDR), Microsoft Purview (data classification and DLP), and Microsoft Defender for Cloud Apps (application access control). All are included or available as part of Microsoft 365 Business Premium or E3/E5.
Q.How long does Zero Trust implementation take in London?
A full Zero Trust implementation for a London SME (20–150 users) typically takes 4–8 weeks with Coreitech: Phase 1 (Week 1–2) — Identity and MFA setup; Phase 2 (Week 2–4) — Device compliance and Intune MDM; Phase 3 (Week 4–6) — Conditional access policies and app control; Phase 4 (Week 6–8) — Data protection and monitoring. We prioritise high-impact controls first.
Q.Is Zero Trust expensive to implement?
For businesses already on Microsoft 365 Business Premium, the core tools for Zero Trust are included at no extra cost — Entra ID, Intune, Defender for Business, and Purview are all part of the licence. The investment is Coreitech's time to configure and deploy these tools correctly. Compared to the average cost of a UK data breach (£3.4 million according to IBM), Zero Trust is highly cost-effective.
