Microsoft 365 Security

A phased program to harden identities, devices and data in Microsoft 365, then keep watch over them.

Most Microsoft 365 tenants already include strong security controls that have never been switched on or tuned. PASY Technology works through them in a deliberate order, starting with the changes that reduce the most risk for the least disruption to your users, and builds toward continuous detection and response.

Close the gaps attackers use first

We begin with identity, because most Microsoft 365 breaches start with a compromised account, then extend protection to devices and the data itself.

First 90 days

  • Put administrator accounts under Privileged Identity Management with least-privilege roles
  • Consolidate multi-factor authentication under Conditional Access policies
  • Turn off legacy authentication and review OAuth app trusts
  • Work through the priority recommendations in Microsoft Secure Score
  • Discover where sensitive data lives and pilot data protection labels

Months 3 to 6

  • Roll out data governance to production: encryption, classification, retention and control of anonymous sharing links
  • Extend Intune enrollment and compliance policies to devices not covered by another MDM

Month 6 onward

  • Enforce Defender for Cloud Apps policies with remediation for high-risk users
  • Deploy hardened Intune configuration baselines
  • Take Microsoft Purview Information Protection to full production
  • Apply conditional access controls to everyone who handles sensitive data

See what is happening in your environment

Controls reduce risk; visibility tells you when something gets past them. We connect your Microsoft signals so suspicious activity is noticed early.

First 90 days

  • Document the security and compliance requirements for regulated data
  • Enable Microsoft Defender for Cloud and connect Microsoft Sentinel

Months 3 to 6

  • Deploy Defender for Identity for intrusion detection across Active Directory and Entra ID
  • Configure automated investigations in Microsoft Sentinel

Month 6 onward

  • Enforce governance policies through Defender for Cloud Apps
  • Use the Microsoft Graph API to automate threat hunting and issue handling

Act quickly and learn from every incident

When an alert is real, the response should be fast, consistent and measurable.

First 90 days

  • Establish investigation and remediation procedures for security alerts
  • Automate incident handling in Defender for Cloud Apps

Months 3 to 6

  • Define and track security KPIs so progress is visible to leadership

Month 6 onward

  • Identify and resolve non-compliant mobile devices
  • Automate incident workflows with Power Automate and Microsoft security insights

Work that runs alongside every phase

Monthly Secure Score review and reassessment
Security awareness training for IT staff and end users, with phishing and data loss as priorities
Monitoring for account and credential abuse
Weekly review of security reports and alert tuning
Threat detection and incident response planning
New or refreshed policies for IT security, data handling, mobile devices, retention and classification
Security coaching for continuous improvement
