Use Case: Securing a Global Healthcare Service Provider with M365, AD, VPN, SIEM & PAM

📌 Client Overview:
A global healthcare provider operating clinics across India and abroad. Facing cybersecurity gaps, compliance issues, and decentralized IT governance, the organization needed scalable and secure infrastructure for their rapid expansion.

🚨 Business Challenges

❌ 1. No Centralized User & Access Management

• Disconnected user directories at different locations
• Weak access and password policies
• No centralized auditing or role enforcement

🔒 2. No Privileged Access Management (PAM)

• Shared administrator credentials across systems
• Lack of session control or accountability

🧾 3. Absence of SIEM & Endpoint Monitoring

• No log correlation or centralized visibility
• Delayed detection of misuses or breaches

☁️ 4. Insecure Cloud Applications

• Banian Cloud-hosted internal apps lacked access control, API protection, and anomaly detection

🦠 5. Weak or Inconsistent Endpoint Protection

• Several endpoints without antivirus or protection policies
• No central control over endpoint hardening
