Case Study: Strengthening Enterprise & OT Security Posture for a Global Pharma Organization

Company Overview

A global pharmaceutical organization operating in a highly regulated environment
wanted to strengthen its information security and OT security posture while ensuring
alignment with ISO/IEC 27001 and NIST SP 800 standards.
The organization faced challenges due to:

Diverse IT and OT environments (manufacturing, labs, SCADA)
Legacy systems with limited native security controls
Increasing regulatory and audit scrutiny (GxP, data integrity, availability)

Objectives

Enhance existing standardized control framework aligned to ISO 27001 and NIST SP 800 with latest revisions
Identify control gaps and overlaps across IT and OT environments
Improve audit readiness and traceability

Stay protected

Approach

Control Mapping & Gap Assessment
1. Mapped existing controls against:
  1. ISO/IEC 27001 Annex A
  2. NIST SP 800 security control families
2. Performed control adequacy and design assessment, identifying:
  1. Fully compliant controls
  2. Partially implemented controls
  3. Control gaps and redundancies
OT Security Control Framework Development
1. 1. Created a dedicated OT security control framework aligned to ISA 62443 requirements.
2. Defined controls across key OT domains:
  1. Asset inventory and classification
  2. Network segmentation and secure architecture
  3. Access control and privileged access in OT
  4. Change management and system integrity
  5. Incident detection and response for OT environments
3. Ensured alignment with operational realities without impacting production
  continuity
Governance, Documentation & Traceability
1. Established clear control ownership across IT, OT, and Quality teams
2. Built traceability matrices linking:
  1. Business risks → Controls → ISO/NIST requirements
