Clarent360 conducts structured Microsoft 365 security reviews that assess your tenant configuration against Microsoft security benchmarks, CIS controls, and your organisation's compliance obligations. M365 environments are complex, rapidly evolving, and frequently misconfigured — creating identity, data, and communication risks that standard deployments leave unaddressed.
Our review methodology covers identity and access management, email security, collaboration controls, conditional access policies, and audit logging — delivering prioritised findings with clear remediation guidance mapped to your risk appetite and regulatory requirements.
End-to-end review of your Microsoft 365 tenant — covering identity, Exchange, Teams, SharePoint, and security policy configurations against benchmark controls.
Review findings mapped to ISO 27001, Essential Eight, NIST CSF, and GDPR — with remediation priorities tied directly to compliance control objectives.
Clarent360 reviews Microsoft 365 security configurations that organisations frequently deploy without validating against security baselines. Default M365 settings are optimised for usability, not security — leaving gaps in authentication enforcement, data sharing controls, legacy protocol exposure, and audit trail completeness.
Our review team works across Exchange Online, Teams, SharePoint, OneDrive, Entra ID, and Defender for M365 — producing a findings register that quantifies risk, maps remediation effort, and gives your team a clear path to a hardened, audit-ready tenant.
Review of conditional access policies, MFA enforcement, guest access controls, privileged role assignments, and legacy authentication exposure.
Assessment of anti-phishing, anti-spoofing, DKIM/DMARC/SPF configuration, transport rules, and mail flow security settings.
Review of external sharing policies, Teams guest access, SharePoint permissions, OneDrive sync restrictions, and data handling configurations.
Assessment of unified audit log configuration, alert policies, sign-in log retention, and integration with SIEM platforms.
A thorough Microsoft 365 security review is not a checklist exercise — it is a structured assessment that connects configuration findings to organisational risk. Each pillar ensures coverage of a distinct security domain within the M365 platform.
Review authentication methods, MFA coverage, conditional access policies, and privileged identity configurations across the tenant.
Assess email security controls — anti-phishing, spoofing protection, mail flow rules, and connector configurations — against current threat vectors.
Evaluate external sharing, guest access, Teams permissions, and OneDrive sync policies to identify data exposure risks.
Review Microsoft Purview sensitivity labels, DLP policies, and information barriers applied across M365 workloads.
Assess audit log coverage, alert policy completeness, and SIEM integration to confirm detection and response capability.
Produce a prioritised remediation register with configuration-level guidance, effort estimates, and compliance mapping.
Clarent360 delivers Microsoft 365 security reviews that produce actionable findings — not lengthy reports that gather dust. Every review outputs a prioritised remediation register, compliance mapping, and implementation-ready configuration guidance for your engineering team.
"A well-configured M365 tenant is one of the most effective security controls available to an organisation. We review it with the rigour it deserves — finding the gaps that default deployments leave open and giving teams a clear path to close them."
