Why Microsoft 365 Security Matters to Insurers
With over a million businesses using Microsoft 365, it’s one of the most targeted cloud ecosystems in the world. Attackers exploit weak access controls, unmonitored mail rules, and misconfigured sharing policies to steal credentials and data—often leading to ransomware incidents and denied insurance claims.
Microsoft’s shared responsibility model means Microsoft secures the platform, but you are responsible for securing your tenant configuration, data, and user access.
When misconfigurations persist or MFA isn’t enforced, insurers flag the environment as high-risk.
eSureITy’s M365 Security Assessment identifies and quantifies those gaps—giving you a documented, defensible security posture that supports both operational resilience and insurability.
Overexposure by Default
Microsoft 365 defaults favor productivity and collaboration over strict security. Without ongoing review, these features become attack vectors:
- Weak Authentication Policies:Users without MFA or conditional access controls.
- Unrestricted Data Sharing:Files shared externally without encryption or expiration policies.
- Overprivileged Admin Accounts:Elevated rights without justification or monitoring.
- Inconsistent Logging & Auditing:Limited visibility into mailbox or SharePoint activity.
- Email Spoofing & Phishing Risks: Lack of SPF, DKIM, or DMARC enforcement.
For organizations bound by HIPAA, PCI, or GDPR, these weaknesses not only expose data—they jeopardize compliance and insurance claims.
Risk-Based M365 Security Assessment
eSureITy’s methodology combines automated Microsoft Secure Score analysis with expert-led configuration auditing to provide actionable results insurers recognize.
Our Assessment Includes:
Authentication & Access Review
- Evaluate MFA enforcement, password policies, and conditional access rules.
Identity & Role Management Audit
- Analyze user groups, admin privileges, and directory synchronization risks.
Email & Content Security Evaluation
- Review mail flow rules, anti-phishing and malware configurations, and data loss prevention (DLP) policies.
Application Permissions Audit
- Identify risky third-party app integrations and legacy protocol dependencies.
Data Protection & Storage Management
- Verify encryption settings for OneDrive, SharePoint, and Teams.
Mobile Device & Endpoint Controls
- Evaluate MFA enforcement, password policies, and conditional access rules.
Authentication & Access Review
- Review Intune configurations and device compliance enforcement.
Audit Logging & Monitoring Verification
- Confirm unified audit log and alerting capabilities are active and retained for required durations.
