Microsoft 365 Security & Management
A Microsoft 365 tenant that is hardened, well run and ready for audit. Identity, email, data and device controls configured properly, plus day-to-day administration and user support.
Service Details
Microsoft 365 security and management gives you a tenant that is configured properly, kept up to date and supported day to day. Microsoft 365 runs your email, files, meetings and sign-ins, which makes it a prime target for attackers. We harden the tenant, run it month to month and support your users, so you get value from the licences you pay for rather than a blind spot.
The service is part of our continuous operations work, alongside the endpoint, identity and cloud services that keep an estate secure over time.
INFO
You get one team responsible for your tenant’s security settings, administration and user support, with every change documented.
Use the security you already pay for
Many Microsoft 365 tenants still run close to default settings. That often means gaps in multi-factor authentication (MFA), overshared SharePoint sites and retention policies nobody configured. Business Premium, E3 and E5 licences include security features that frequently sit unused.
We close that gap with hardened baselines, identity controls switched on and data loss prevention that matches how your teams share files. We also handle the everyday side, from licence reviews to Teams governance, so security does not get in the way of work.
Who this service is for
This service suits organisations that rely on Microsoft 365 but lack the time or specialist knowledge to secure it. That might be a small internal IT team stretched across everything, or a business with no IT staff at all.
It also suits firms facing an audit, a client security questionnaire or a regulator’s questions about access control. If you are planning to roll out Microsoft 365 Copilot, a tenant review first shows you what Copilot would be able to see.
What a hardened tenant includes
Controls across identity, email, data and collaboration:
Identity Protection
MFA for every account, Conditional Access policies in Microsoft Entra ID, and legacy sign-in methods blocked. Risk-based policies where your licences include Entra ID P2.
Email Security
Microsoft Defender for Office 365 policies for phishing, malicious links and attachments, plus SPF, DKIM and DMARC records to stop spoofing of your domain.
Data Protection
Microsoft Purview sensitivity labels, data loss prevention (DLP) and retention policies that limit oversharing without blocking work.
Teams and SharePoint Governance
Naming, ownership, guest access and lifecycle policies so collaboration spaces stay tidy and controlled.
Device Management
Laptops and phones enrolled in Microsoft Intune, with compliance policies that feed Conditional Access decisions.
Secure Score Tracking
Microsoft Secure Score reviewed regularly, with changes explained and reported so you can see progress over time.
How we work
You move from your current configuration to a hardened, documented tenant in planned stages, without disrupting how people work.
- Review — We assess your tenant against Microsoft guidance and the CIS Microsoft 365 benchmark, and check which security features your licences already include.
- Prioritise — You get a list of findings ranked by risk and effort, so the most important fixes come first.
- Harden — We make changes in agreed windows, test them with pilot users and document every setting.
- Administer — Ongoing administration keeps policies current as Microsoft changes the platform and your business changes around it.
From default tenant to defended tenant
Microsoft regularly moves settings, renames products and adds features. Ongoing administration means your baseline keeps up, joiners and leavers are handled properly, and new risks are dealt with before they become incidents.

Getting ready for Copilot
Microsoft 365 Copilot works with the permissions your users already have. If a SharePoint site is shared with the whole organisation, Copilot can draw on it in answers to anyone. Before you switch it on, we review sharing and permissions, label confidential content with Purview and remove access people no longer need.
For wider questions about AI risk, our AI and machine learning security team can help you set rules for how AI tools use your data.
Evidence for audits and accreditations
A well-run tenant produces the evidence auditors ask for: MFA coverage, access reviews, audit logs and retention settings. That supports Cyber Essentials, ISO 27001 and UK GDPR programmes. Our compliance support team can turn it into a pack ready for your auditor.
Services that work alongside
Tenant security also depends on devices and people. Endpoint management keeps devices compliant so Conditional Access can trust them, and identity and access covers sign-in controls beyond Microsoft 365. User awareness training helps staff spot the phishing that targets their inboxes.
Day-to-day support can sit inside managed services, and automations and integrations can take repetitive admin off your team. If you run Google instead, see Google Workspace. For the bigger picture, our digital workplace solution brings these services together.
A tenant that labels its own content
We deployed data loss prevention and sensitivity labels across Microsoft 365, reaching 100% coverage, with confidential content blocked from AI assistants such as Copilot. The tenant now protects its own material instead of relying on people remembering.
