You own Microsoft 365. Is anyone actually managing it?

You are running Microsoft 365, but no one is actively governing it. Your Secure Score is unknown or low, and an insurer or auditor has started asking questions you cannot answer. Identity is sprawling, the joiners and leavers process is manual, and an estimated 29% of your licences are sitting unused while Microsoft raises prices again on 1 July 2026. Meanwhile a one to five person team is expected to run governance, security, identity, endpoints and a service desk at the same time. That is structurally impossible.

We take ownership of your Microsoft 365 estate and run it to a defined standard:

  • Identity and access — Entra ID joiner, mover and leaver lifecycle, MFA, Conditional Access, SSO, self-service password reset and Privileged Identity Management.
  • Endpoint management — Intune device compliance across Windows, macOS, iOS and Android, Windows Autopatch, Autopilot zero-touch provisioning and BYOD app protection.
  • Threat protection — Defender for Endpoint and Office 365, anti-phishing, safe links and safe attachments, with Secure Score monitoring and a managed improvement roadmap.
  • Data and compliance — Purview DLP, sensitivity labels, retention and Compliance Manager, with continuous, documented compliance evidence.
  • Collaboration — Exchange Online, Microsoft Teams governance and Teams Phone where applicable.
  • Information governance — SharePoint Online and OneDrive site, permissions and storage governance.
  • Service desk — L1 and L2 support with defined SLAs, a self-service portal, and shift-left automation at higher tiers.

Service tiers

Three tiers, so you can start where your need and budget sit and grow with us:

Premium

Everything in Enhanced, plus 24/7 cover, advanced security with Arctic Wolf managed detection and response, and a dedicated Service Delivery Manager.

Why Northdoor?

  • Proven, not promised — We quantify the misconfiguration, licensing waste and the security gaps in a fixed-fee health check before you commit a penny.
  • Senior-led and independent — 37 years independent and never acquired, with named senior contacts, not an offshore, shared-service desk.
  • Regulated-sector depth — FSQS registered and built to a financial-services standard, with continuous compliance evidence for Cyber Essentials and cyber insurance.
  • The whole estate — Combined IBM and Microsoft capability, not just another Microsoft-only partner.

The health check

Every engagement starts with a free M365 Health Check and Security Audit. We assess your environment configuration, tell you your Secure Score, show you the licences you are paying for and not using, and confirm whether you are safe for Copilot, in days not weeks. You see the value before you commit a penny. Then a Statement of Work to remediate, followed by an ongoing managed service.

Proven in financial services

Regulated firms trust Northdoor to run business-critical Microsoft estates. Here is what that looks like in practice.

20%

cut in associated costs when Ocorian moved its SQL Server estate to a Northdoor managed service.

29%

of SaaS licences typically sit unused. The Health Check finds them before you renew.

37 years

independent and privately owned. The same senior team runs your service, not a rotating pool.

Microsoft 365: your questions answered

Everything you need to know about the health check, licensing and Copilot readiness.

In the health check we review your M365 configuration, including the Secure Score, Defender configuration, identity and Conditional Access set-up, and data governance, then give you a prioritised, quantified improvement roadmap.

Yes. We identify unused and wrong-tier licences and quantify the saving in pounds, and the optimisation usually pays for the service.

Copilot readiness is mainly a data question: where your sensitive information sits and how well it is governed. The health check reviews your data governance, sensitivity labelling, DLP and licensing, so you can switch Copilot on safely rather than hoping for the best.

Microsoft list prices have risen 25% to 40% over the past three years, and rise again on 1 July 2026. We model the impact on your estate and remove waste ahead of your renewal.

Yes. We are FSQS registered with genuine financial-services depth, and we provide the continuous compliance evidence regulators and insurers now expect.

UK organisations of roughly 50 to 300 users on Microsoft 365 Business Premium, E3 or E5, with a small in-house IT team and no dedicated security resource.

Yes. The health check shows which licensed capabilities you are not yet using, and we run focused projects to roll them out and drive adoption, so your investment delivers its full value rather than sitting idle.

Stop paying for what you are not using

Make sure the capabilities you already pay for are actually adopted, and prove your estate is secure and Copilot-ready. Book your free M365 Health Check and Security Audit.
