Microsoft 365 Security Service

Secure Your Microsoft 365 Environment

Microsoft 365 is at the core of many modern business operations, but without the right configuration and governance, it can quickly become one of your biggest security risks. From misconfigured identities to uncontrolled sharing, attackers often exploit weak points in cloud services.

Our Microsoft 365 Security Service is designed to give you confidence that your tenant is secure, resilient, and aligned to recognised security standards. Whether you need a one-off health check or ongoing governance and protection, we provide the expertise to safeguard your environment.

Crucially, the service is tailored to your business profile. We shape security configurations around your operating model, industry regulations, and risk appetite, while also considering the working practices of your users and business. This ensures the right balance between security, operational effectiveness, and efficiency. At the same time, we review your Microsoft 365 licensing to confirm you are using the correct licence models to unlock security features cost-effectively — helping you achieve best value from the platform while realising the benefits of robust security controls.

Why This Matters

  • Balance Security and Productivity – Apply controls that protect the business without disrupting how your teams work.

Frequently Asked Questions

While Microsoft provides a secure cloud foundation, responsibility for configuring, monitoring, and managing your tenant sits with your organisation. Many breaches occur due to misconfigurations, overly permissive access, or underused security features. Our service ensures your tenant is aligned to best practice and tailored to your specific business needs.

The assessment reviews your Microsoft 365 environment against recognised security standards and Microsoft best practices. You’ll receive a clear report detailing risks, misconfigurations, and practical recommendations for improvement, along with a consultant-led review session to explain the findings.

The ongoing service builds on the initial assessment by providing continuous monitoring, maintenance, and governance. It includes implementing recommendations, aligning with security standards (ISO 27001, Cyber Essentials Plus, NCSC guidance), and regular reassessments to keep your security posture current.

No — we consider the working practices of your users when designing and applying security controls. Our aim is to maintain the right balance between security, usability, and efficiency, ensuring staff can remain productive without compromising protection.

Yes. Microsoft 365 licensing can be complex, and some of the most valuable security and compliance features are only available at enhanced licence levels (for example, Microsoft Defender for Office 365, Azure AD Premium, or advanced auditing). As part of the service, we review your current licences and identify where you may be overpaying for features you don’t use or missing out on features you need.

Our consultants ensure you’re on the most cost-effective licence model to access the right security capabilities — balancing protection, compliance requirements, and budget. This means you get the full benefit of Microsoft 365 security features without unnecessary costs.

We recommend at least once per year for static environments, or more frequently if your organisation is undergoing change (e.g., growth, mergers, increased compliance requirements). The ongoing service includes periodic reassessments as standard.

Yes. Our ongoing service can be mapped against frameworks such as ISO 27001 and Cyber Essentials Plus, providing the evidence and assurance needed to support certification.

All assessments and ongoing management are delivered by accredited Microsoft and cybersecurity consultants with proven experience in Microsoft 365 security, compliance, and governance.
