Is Your M365 Tenant Secure?
We audit hundreds of M365 tenants. Here are the most common security gaps we find:
No Conditional Access
Anyone can sign in from any device, anywhere
MFA Not Enforced
Accounts vulnerable to password spray attacks
Legacy Authentication Enabled
Bypasses MFA, enables brute force attacks
Default Sharing Settings
Sensitive files shared externally by default
No DLP Policies
PII, PHI, financial data leaves organization
Defender Not Configured
Missing advanced threat protection

Frequently Asked Questions
Will this disrupt our users?
We implement changes in stages with pilot groups to minimize disruption. Most changes are transparent to users. For changes that affect user workflow (like MFA enrollment), we provide communication templates and coordinate timing with your team.
What M365 licenses do we need?
Basic hardening works with Business Basic/Standard. For full protection (Defender for Office 365, advanced Conditional Access, PIM), you need Microsoft 365 Business Premium or E3/E5. We'll assess your current licenses and recommend the most cost-effective path.
How does this compare to Microsoft Secure Score?
Secure Score is a good starting point but doesn't capture everything. We implement controls that Secure Score misses, validate that controls actually work (not just enabled), and prioritize based on real-world attack patterns rather than arbitrary scores.
Do you support hybrid environments?
Yes. We secure both cloud-only and hybrid (on-premises AD synced with Entra ID) environments. For hybrid setups, we also review AD Connect configuration and synchronization security.
What about ongoing maintenance?
Security configuration requires ongoing attention as Microsoft releases new features and threats evolve. We offer quarterly security reviews or ongoing managed security services to keep your tenant protected.
Can you help with compliance requirements?
Yes. Our hardening addresses technical requirements for SOC 2, HIPAA, CMMC, and other frameworks. We document all configurations for audit evidence and can coordinate with your compliance team or auditors.
What if we have custom applications in M365?
We review app registrations, API permissions, and consent settings as part of the engagement. We'll identify overprivileged apps, unused applications, and configure app governance policies.
How do you handle existing security settings?
We don't blindly overwrite your configuration. We assess what's already in place, identify what's working, and build on existing security investments rather than starting from scratch.
