Your Microsoft tenant holds your emails, files, Teams conversations, and business data. Most tenants are not secure by default - and attackers know exactly where to look. We audit your setup, close the gaps, and harden your environment so you stay protected.
Microsoft 365 is the backbone of most businesses. But it ships with permissive defaults that leave real gaps in your security posture - gaps attackers actively exploit.
Multi-Factor Authentication is the single most effective control against account takeover - but in many tenants it is not consistently applied across all users and apps.
Old authentication protocols like IMAP and SMTP Auth do not support MFA. Leaving them enabled gives attackers a side door into your accounts.
Default SharePoint, Teams, and OneDrive settings allow broad sharing - including with anyone who has a link. This is rarely what your business actually needs.
Too many users with Global Admin rights, no separation between admin and day-to-day accounts. One compromised login becomes a full tenant breach.
What we see in practice We regularly find tenants where key protections simply have not been set up properly - leaving businesses exposed without even realising it. These are not edge cases. They are the norm.
Tenant hardening is the process of securing your Microsoft 365 environment by tightening configurations, removing unnecessary access, and applying security best practices across identity, data, devices, and communication.
Protects
User identities and login credentials from being compromised or impersonated.
Controls
How and where people can access your data, from which devices and locations.
Locks Down
External sharing and collaboration settings across SharePoint, Teams, and OneDrive.
Monitors
Activity across your environment to detect threats and suspicious behaviour early.
We work across five areas of your Microsoft environment. Each builds on the last to give you layered, practical protection.
Not sure where your gaps are?
Our free assessment tells you exactly where you stand - and what matters most.
Book AssessmentThese are not rare edge cases. We see these issues in the majority of tenants we audit - regardless of business size or how long they have been on Microsoft 365.
| Finding | Risk Level | Business Impact |
|---|---|---|
| MFA not enforced for all users | Critical | Account takeover via credential stuffing or phishing |
| Legacy authentication protocols enabled | Critical | Bypasses MFA entirely - primary attack vector |
| No Conditional Access policies | High | No controls on where or how accounts are accessed |
| Over-permissioned users or Global Admins | High | One breach becomes a full tenant compromise |
| Open external sharing in SharePoint / OneDrive | High | Business data accessible by anyone with a link |
| No device compliance policies (Intune) | Medium | Unmanaged personal devices accessing company data |
| Audit logging not configured | Medium | No visibility of what happened during or after a breach |
| Permissive mail forwarding rules | Medium | Emails silently forwarded to external addresses |
We do not overwhelm you with a 40-page report. We give you a clear picture of your risks, prioritise what matters, and fix it - without disrupting your team.
We run a detailed audit of your Microsoft 365 tenant - reviewing identity controls, sharing settings, email security, device policies, and your Secure Score. You get a clear baseline of where you stand, including quick wins and critical gaps.
We break every finding into three buckets: fix now, fix soon, and optional improvements. No jargon, no overwhelm. Just a clear plan tied to real business risk so you know exactly what to tackle first.
We implement the changes across your tenant - carefully, with full documentation, and in a way that does not disrupt your team's day-to-day work. Every change is aligned to how your business operates.
Security is not a one-off job. We monitor changes in your environment, track your Secure Score, adapt to new threats, and provide regular recommendations to keep your posture improving over time.
The goal is not compliance for its own sake. It is a Microsoft environment that is genuinely harder to breach, easier to manage, and built to support your business long term.
Significantly reduced attack surface. Closing the gaps attackers rely on means most common attack paths are blocked before they start.
Know what is happening in your environment. Audit logs, alerts, and monitoring in place so nothing goes undetected.
Better positioned for GDPR, Cyber Essentials, and cyber insurance requirements. A hardened tenant is a well-documented one.
Email security controls, Safe Links, and Safe Attachments working properly - reducing the chance of a successful phishing attack reaching your team.
Your Microsoft Secure Score tracked and improved over time. A tangible measure of your security posture that you can report to leadership and insurers.
Confidence that your Microsoft environment has been configured by people who know what they are doing - not left on defaults and hoped for the best.
Not if it is done properly. We plan all changes carefully and implement them in stages where needed. We communicate with your team before making changes that affect their workflow - for example, when rolling out MFA or Conditional Access. Most changes happen invisibly in the background.
Some security features require Business Premium or higher licences - for example, Conditional Access, Intune device management, and advanced threat protection. We assess what you have and tell you exactly what is available to you. Where a licence upgrade would materially improve your security, we will tell you - but we never upsell unnecessarily.
The initial assessment typically takes a few hours of our time. We will need delegated admin access to your tenant to run the audit properly. You will receive a clear written report within a few working days, covering findings and prioritised recommendations.
Absolutely. Many of our clients have internal IT staff or another MSP who handles day-to-day support. We can deliver the assessment and hardening as a standalone project, hand back full documentation, and leave your team in complete control. We are not trying to replace what you have - just to make it more secure.
Yes. Many of the controls we implement align directly with the Cyber Essentials and Cyber Essentials Plus requirements - particularly around access control, MFA, and device management. A hardened Microsoft 365 tenant puts you in a much stronger position for certification.
We offer ongoing monitoring and Secure Score tracking as part of our managed service. As Microsoft evolves - new features, new threats, new best practices - your configuration needs to evolve too. We keep an eye on it so you do not have to, and flag anything that needs your attention.
