Why a default Microsoft 365 tenant is not secure
A new tenant ships to get you working quickly, not to withstand a targeted attack. Legacy authentication paths may remain reachable, external sharing is often permissive, mailbox auditing and alerting go unconfigured, and global administrator accounts are used for daily work.
The most common incident we clean up is business email compromise: a credential is phished, MFA was never enforced, an inbox rule quietly forwards invoices, and a payment goes to the wrong bank account. Nearly every control that would have prevented it is already included in the licensing most businesses hold.
Controls we configure
Remediation is prioritized by risk and disruption, so the highest-impact controls go in first and staff are told what to expect.
- Multi-factor authentication deployment and enforcement
- Microsoft Entra ID identity and access hardening
- Conditional Access policies for locations, devices and risk
- Microsoft Defender for endpoints, identity and Office 365 workloads
- Email security, anti-phishing configuration and spam protection
- Endpoint security, device compliance and Intune policies
- User access controls and least-privilege review
- Secure, separated administrator accounts with break-glass procedure
- Security configuration reviews and Microsoft 365 security assessments
The Microsoft 365 security assessment
The assessment reviews identity configuration, MFA and Conditional Access coverage, admin role assignments, mailbox rules and forwarding, sharing and guest access, device compliance, Defender policy state, retention and backup posture.
You receive a written report with each finding rated by severity, the business risk in plain language, and the remediation effort. Most items are configuration changes covered by licensing you already own.
- Identity, MFA and Conditional Access coverage review
- Administrator role and privileged access audit
- Mailbox rule, forwarding and sharing exposure check
- Defender, Intune and compliance policy review
- Prioritized remediation roadmap with effort estimates
