Securing Microsoft 365 to Recognised Standards
Most Irish businesses run Microsoft 365 without ever fully hardening it. Our goal is to change that. We use industry-recognised benchmark tooling, including CIS Benchmarks, NCSC-IE M365 Baseline Standards, and Microsoft’s own Scuba assessment tool, to evaluate your tenant against a consistent, measurable standard. We then map findings to the GRC frameworks your organisation is most likely working towards, including CyFun, NIS2, and DORA. The result is not just a list of technical gaps. It is a clear picture of where your M365 environment stands, what it means for your compliance posture, and what to fix first.
Microsoft 365 Is Only as Secure as Its Configuration
Microsoft 365 ships with powerful security capabilities. Most tenants never fully use them. Identity controls left on default settings, MFA enforcement gaps, misconfigured external sharing, and incomplete email authentication create entry points that attackers know how to find.
Our Microsoft 365 assessment reviews your entire tenant against recognised M365 baseline standards. We check your M365 Secure Score, evaluate your security settings across Exchange, Teams, SharePoint, OneDrive, and Entra ID, and give you an honest picture of where your environment stands.
This is not a theoretical review. It is a practical, expert-led assessment of the M365 security configurations that determine whether your organisation is protected or exposed.
Our Microsoft 365 Security Assessment service is designed to help businesses in Ireland improve their security posture by evaluating their current environment and providing actionable recommendations to strengthen their security. Our assessment process consists of five steps:
Find Out What’s Misconfigured in Your M365 Tenant
No commitment. We’ll help identify your biggest risks fast.
What Our Microsoft 365 Assessment Covers
We carry out a comprehensive review of your M365 tenant, benchmarked against the NCSC-IE M365 Baseline Standards, CIS Benchmarks, and NIST Guidelines. Our assessment covers:
- Identity and Access Controls We review Entra ID (Azure AD) configurations, conditional access policies, privileged account protections, and MFA enforcement across your user base.
- M365 Security Settings and Configurations We evaluate security settings across Exchange Online, Microsoft Teams, SharePoint, and OneDrive, including external sharing policies, app registration controls, and guest access permissions.
- Email Security and Domain Protections We assess your SPF, DKIM, and DMARC configurations, anti-phishing policies, and Safe Links and Safe Attachments settings under Microsoft Defender for Office 365.
- M365 Secure Score and Baseline Alignment We review your Microsoft Secure Score against your industry peers and map your environment against the M365 baseline to identify the controls with the greatest impact.
- Compliance Logging and Audit Readiness We check that audit logging is enabled, retention policies are correctly configured, and your environment meets the evidence requirements for ISO 27001, NIS2, and DORA.
- M365 Pen Test Readiness We identify the configuration weaknesses most commonly targeted in Microsoft 365 penetration tests, helping you close gaps before a formal test or attacker finds them.
A Clear, Prioritised Report Your Team Can Act on Immediately
At the end of the assessment, you receive a concise, executive-ready report that your IT team can act on immediately. It includes:
- A baseline compliance score mapped to NCSC, CIS, and NIST standards
- Critical findings ranked by risk and business impact
- Specific, practical remediation steps for each issue
- A longer-term roadmap for sustained M365 security and compliance
- Optional support from our team to implement changes directly

Benefits of our m365 security assessment
Stop attackers exploiting gaps Microsoft cannot see
Identify and remediate the misconfigurations most commonly exploited in Microsoft 365 environments before they become incidents.
Know exactly what to fix, and in what order
A prioritised remediation plan means your team focuses effort where it matters most, not on a list of 200 low-risk findings.
Stay ahead of NIS2, ISO 27001, and DORA requirements
Proper M365 security and compliance configuration provides documented evidence for audit purposes and reduces your exposure during regulatory reviews.
Improve your M365 Secure Score with purpose
Move your Secure Score based on expert-led prioritisation, not automated suggestions that do not account for your specific environment and risk tolerance.
Gain complete visibility across your tenant
Understand how your M365 security settings perform across users, apps, devices, and data, including areas you may not have reviewed since initial deployment.
Build lasting resilience, not a one-time fix
Establish drift detection and monitoring practices that keep your M365 baseline controls effective over time.
FAQ's
What is an M365 Baseline and why does it matter?
An M365 baseline is a defined set of security configurations that every Microsoft 365 tenant should meet as a minimum standard. Bodies such as NCSC-IE and CIS publish these baselines based on real-world threat intelligence and security best practice. Without measuring your tenant against a recognised baseline, you have no consistent way of knowing whether your environment is adequately protected or drifting over time. Our assessment uses these baselines as the benchmark for every finding we report.
What is Microsoft Secure Score and should I be worried if mine is low?
Microsoft Secure Score is a built-in measurement of your security posture across your M365 environment. It scores your tenant based on the controls you have enabled relative to those available to you. A low score does not always mean you are at high risk, and a high score does not always mean you are fully protected, because Secure Score does not account for how controls are configured, only whether they are enabled. Our assessment goes beyond the score to evaluate the quality and consistency of your actual security settings.
How is this different from what our IT team or managed service provider already does?
Most internal IT teams and managed service providers focus on keeping Microsoft 365 running rather than hardening it against attack. Day-to-day administration and security configuration are different disciplines. Our assessment is carried out by dedicated security consultants using specialist tooling, including ScubaGear and CIS Benchmarks, and is benchmarked against standards your internal team may not have the time or resource to apply. Many of our findings come from environments that are actively managed by competent IT teams.
Can the assessment help us meet our cyber insurance requirements?
Yes. Cyber insurers increasingly require evidence that cloud environments such as Microsoft 365 are configured to a recognised security standard. MFA enforcement, email authentication controls, and privileged access management are among the most commonly assessed areas during underwriting. Our report provides documented evidence of your security posture and the steps you have taken to address identified gaps, which can support both new applications and renewals.
What if we have already done a Microsoft 365 assessment in the past?
M365 environments change constantly. New users are added, applications are connected, policies are updated, and Microsoft itself rolls out changes that can affect your security configuration. An assessment carried out 12 or 18 months ago may not reflect your current posture. We recommend reassessing annually as a minimum, and our team can also implement ongoing drift detection to alert you when configurations fall outside your agreed baseline between formal reviews.
What happens after I receive the assessment report?
Beyond the report, we can support you with remediation, retesting, and ongoing assurance. This includes follow-up security assessments, vulnerability scanning, and penetration testing to validate improvements and ensure your Microsoft 365 environment remains resilient over time.
Is this relevant for my Compliance Journey?
Absolutely. Proper cloud security configuration directly supports ISO27001, NIS2 and DORA’s requirements for digital resilience testing. The assessment provides documentation you can use as evidence for most compliance frameworks.
