Client Overview: Our client, a rapidly growing technology company, required a strengthened Microsoft 365 security posture, improved compliance controls, and proactive monitoring to protect sensitive IP and customer data. Their existing Microsoft 365 setup lacked consistent security policies, centralized monitoring, and automated compliance workflows. NVITS, with deep expertise in Microsoft 365 security and managed services, was engaged to design and implement a comprehensive security, compliance, and monitoring solution.

Preparation

Initial Consultation

NVITS conducted an executive-level and technical consultation to understand the company’s risk profile, regulatory obligations, and business priorities. This helped shape a tailored security and compliance roadmap aligned with their growth plans.

Detailed Assessment

Security Posture Audit

We performed a full audit of their Microsoft 365 environment, including identity configuration, Exchange Online, SharePoint, OneDrive, Teams, and endpoint integrations.

Compliance Gap Analysis

Compliance requirements (e.g., GDPR, industry-specific standards) were reviewed and compared against current controls to identify gaps and remediation priorities.

Threat & Vulnerability Assessment

We ran vulnerability scans and threat simulations to uncover weaknesses in identity management, email security, data leakage paths, and configuration drift.

Strategy & Roadmap

Risk-Based Prioritization

NVITS prioritized actions using a risk-based model—addressing high-impact, high-likelihood threats first while aligning with compliance deadlines.

Timeline and Milestones

A phased timeline with clear milestones was established to implement identity hardening, data protection, threat prevention, and monitoring incrementally.

Resource Allocation

A cross-functional team of security architects, compliance specialists, and M365 engineers was assigned to lead the project and provide ongoing managed services.

Implementation

Identity & Access Management

Azure AD Hardening: Implemented conditional access policies, role-based access controls (RBAC), and identity protection to reduce attack surface.

Multi-Factor Authentication (MFA): Enforced MFA across all users and privileged accounts with step-up authentication for sensitive operations.

Email & Endpoint Security

Microsoft Defender for Office 365: Deployed advanced phishing and malware protection, safe attachments, and safe links.

Endpoint Integration: Integrated Microsoft Defender for Endpoint for device posture checks and automated remediation workflows.

Data Protection & Information Governance

Microsoft Information Protection (MIP): Classified and labeled sensitive data across Exchange, SharePoint, OneDrive, and Teams.

Data Loss Prevention (DLP): Implemented organization-wide DLP policies to prevent accidental or malicious data exfiltration.

Compliance Automation

Compliance Manager & eDiscovery: Configured Compliance Manager controls, retention policies, legal holds, and eDiscovery workflows to support audits and litigation readiness.

Audit Logging & Records Management: Centralized audit logs and set long-term retention for critical compliance artifacts.

Configuration & Baseline Management

Applied security baselines and configuration policies via Microsoft Endpoint Manager and Intune to ensure consistent, compliant device configurations.

Monitoring & Detection

SIEM & Alerting

Azure Sentinel: Deployed Azure Sentinel as the central SIEM for ingesting Microsoft 365 signals, custom analytics, and incident orchestration.

Automated Playbooks: Built automation playbooks to triage common incidents, block malicious actors, and initiate remediation steps.

Continuous Threat Hunting

NVITS performed proactive threat hunting using telemetry from Defender, Sentinel, and endpoint logs to identify anomalous behavior and advanced threats.

24/7 Monitoring & SOC Integration

Integrated the client’s environment with NVITS-managed SOC capabilities for 24/7 monitoring, investigator-led response, and regular threat briefings.

Training, Awareness & Adoption

Security Awareness Training

Delivered targeted security awareness workshops covering phishing, secure collaboration, and data handling best practices for technical and non-technical staff.

Admin & IT Training

Provided hands-on training for IT and security teams on Sentinel playbooks, MIP label management, DLP tuning, and incident response procedures.

Support Materials

Created runbooks, response playbooks, user guides, and quick-reference documentation to accelerate incident response and governance operations.

Post-Implementation Monitoring and Management

Ongoing Managed Services

NVITS provided continuous managed detection and response (MDR), regular security posture reviews, and maintenance of compliance controls.

Patch & Configuration Management

Regular patch cycles and baseline configuration checks were scheduled to reduce exposure to known vulnerabilities.

Reporting & Governance

Delivered regular security and compliance reports, KPI dashboards, and executive summaries to track improvements and highlight risks.

Outcome

Results Achieved

  • Hardened Identity Security: Conditional access and MFA significantly reduced successful credential-based attacks.
  • Improved Data Protection: MIP labeling and DLP policies prevented sensitive data leaks and simplified compliance.
  • Proactive Detection: Sentinel and Defender integration enabled faster threat detection and automated response.
  • Regulatory Readiness: Compliance Manager, retention policies, and audit logging improved the company’s audit posture.
  • Operational Resilience: 24/7 monitoring and NVITS-managed SOC reduced mean time to detect (MTTD) and mean time to respond (MTTR).
