Microsoft 365 Hardening Review
Optimize Your Microsoft 365 Environment
TrustedSec’s Microsoft 365 Hardening Review evaluates your organization’s Microsoft 365 tenant to identify security gaps and configuration weaknesses to strengthen identity and data protection. Our experts help align your Microsoft environment with industry best practices to reduce risk, improve visibility, and ensure sustainable governance.
A Complete Review of Your Microsoft 365 Security Controls
Microsoft 365 powers the modern workplace, but its range of configuration options can leave organizations exposed when mismanaged. Without a structured review, overprivileged roles, weak settings, or unsecured tools can open critical paths for attackers.
TrustedSec’s hardening review delivers a focused evaluation across Exchange Online, SharePoint, OneDrive, Teams, and Entra ID to ensure your environment is configured for maximum security and compliance.
