Cyber Security Assessment Common Questions.
Common questions about cyber security assessments, answered for Irish businesses looking to identify vulnerabilities, meet GDPR and NIS2 requirements, and strengthen their Microsoft 365 security posture.
What is a cyber security assessment and why does an Irish business need one?
A cyber security assessment is a structured review of your business’s systems, configurations, and processes to identify security weaknesses before they are exploited. For Irish businesses, the most common triggers for getting an assessment are a concern about GDPR compliance after becoming aware of how much personal data the business holds, a NIS2 obligation assessment following the 2025 Irish transposition, a cyber insurance requirement, a client or partner asking for evidence of security controls, or a change in the business such as moving to remote working or adopting Microsoft 365. The output of a Mata365 cyber security assessment for an Irish business is not a generic compliance checklist but a specific, prioritised list of vulnerabilities and gaps with clear remediation guidance based on your actual environment.
What does a cyber security assessment cover for an Irish Microsoft 365 business?
A Mata365 cyber security assessment for an Irish business covers four main areas. The Microsoft 365 security configuration review examines your tenant settings against Microsoft best practice and Secure Score recommendations, including MFA coverage, conditional access policies, Microsoft Defender configuration, email protection settings, external sharing controls in SharePoint and Teams, and admin role assignments. The identity and access review examines who has access to what, including privileged accounts, guest access, and former staff accounts that remain active. The data protection review assesses how personal and sensitive data is classified, stored, shared, and retained in your Microsoft 365 environment against GDPR Article 32 requirements. The network and endpoint review identifies exposures in how devices connect to your business systems, including personal devices used for work and any legacy on-premise infrastructure still in use.
How long does a cyber security assessment take for an Irish SME?
For most Irish SMEs, a Mata365 cyber security assessment takes between five and ten business days from kick-off to final report delivery. The first two days cover scoping, access configuration, and initial data collection. Days three to six cover the active assessment work including Microsoft 365 configuration review, vulnerability scanning, identity and access analysis, and data protection evaluation. The final days cover report writing, finding validation, and preparing the prioritised remediation roadmap. The assessment causes no disruption to your Irish business operations, as all evaluation work is conducted through read-only access to your Microsoft 365 tenant and any other agreed systems, with no changes made to your environment during the assessment.
What is the difference between a cyber security assessment and a Microsoft Secure Score review?
Microsoft Secure Score is a useful tool that measures your Microsoft 365 tenant’s security posture against a set of Microsoft-defined controls and shows a score out of 100. A full cyber security assessment goes significantly further. Secure Score only evaluates Microsoft 365 tenant-level controls, and the improvement actions it recommends are not always prioritised by actual risk to your Irish business. A Mata365 cyber security assessment evaluates your full environment including network infrastructure, endpoint security, identity management, data protection controls, and regulatory compliance, then prioritises findings by the likelihood and potential business impact of each risk rather than by the Microsoft scoring model. For Irish businesses that need to understand their real risk exposure, not just their Microsoft tenant score, a full assessment provides significantly more actionable insight.
Does a cyber security assessment help with GDPR compliance for an Irish business?
Yes. GDPR Article 32 requires Irish businesses to implement appropriate technical and organisational security measures, and to be able to demonstrate that those measures are in place and effective. A cyber security assessment provides the evidence base for that demonstration, identifying which technical controls are in place, which are absent or misconfigured, and what the residual risk is. The assessment report and the remediation plan it generates can be used as evidence in a Data Protection Commission investigation to show that the business takes its GDPR security obligations seriously. Mata365 structures the assessment output for Irish businesses to map directly against the Article 32 technical measure requirements so the report is usable as compliance documentation as well as an operational security roadmap.
