CYFOR Secure's Office 365 Security Audit is an expert-led security assessment service targeting Microsoft 365 tenancy environments. The audit identifies misconfigurations, privilege mismanagement, and security gaps across Microsoft 365 services including Exchange, SharePoint, OneDrive, and Teams. The service reviews the status and configuration of key security controls such as logging, alerting, multi-factor authentication (MFA), conditional access policies, and threat protection features. Auditors also assess for suspicious activity, login anomalies, and data access issues within the tenant. Upon completion, clients receive a written report detailing identified risks, potential exploitation paths, and step-by-step remediation guidance to harden the environment. The service also covers account compromise recovery and access to historical logs for investigative purposes. The audit is applicable to organisations preparing for compliance (including GDPR alignment), responding to a suspected security incident, or seeking a general security posture review of their Microsoft 365 environment. It can be extended into a broader Cyber Security Audit engagement.
