Strengthening Microsoft 365 Security with Baseline Controls

Challenge

A growing organization needed to improve its Microsoft 365 security posture and reduce identity, email, and password-related risk. Before the engagement, the client needed practical answers: How secure is the current tenant? Which baseline controls should be prioritized first? How can users be better protected from phishing, spoofing, unsafe links, and malicious attachments? How can identity protection be improved without overbuilding the environment? The scope was intentionally focused — strengthening the tenant using existing Microsoft 365 capabilities without expanding into endpoint management, device encryption, or third-party integrations.

Approach

Safari Micro began with a Microsoft 365 Secure Score assessment to establish a baseline view of the tenant's security posture. The engagement then implemented a structured set of baseline controls: (1) identity protection — multi-factor authentication and self-service password reset to reduce account takeover risk and IT overhead; (2) email security — anti-phishing, anti-spoofing, Safe Attachments, and Safe Links policies through Microsoft Defender for Office 365; (3) data protection — secure email encryption configuration for safer handling of sensitive communications; and (4) password policy configuration aligned to stronger identity hygiene. Microsoft 365 Business Premium licensing upgrade support was also provided as part of the engagement.

Results

• Stronger protection against credential compromise through MFA implementation
• Improved user account recovery through self-service password reset configuration
• Better defense against phishing, spoofing, malicious attachments, and unsafe links
• Clearer Microsoft 365 security posture visibility through Secure Score assessment
• Improved email data protection through secure encryption configuration
• Password policies reviewed and configured for stronger identity hygiene
• More mature Microsoft 365 security baseline delivered without expanding into unrelated infrastructure work
