THE COMPLEXITY OF GxP ENVIRONMENTS

Why pharmaceutical production requires controlled remote access

Pharmaceutical manufacturing is built on validated batch processes controlled through PLCs, SCADA, and MES systems. From process equipment and skids to filling and packaging lines, every interaction with production systems must be controlled and traceable.

But when connectivity relies on VPNs, shared credentials, or ad hoc tools, control weakens, and traceability is lost. In a GxP environment, that introduces compliance risk.

Validated systems require attributable access, not IT-style security

Pharmaceutical production systems must remain in a validated state, and all interactions must be documented and controlled. Agent-based or IT-centric security approaches can impact system integrity or require revalidation, limiting how safely remote access can be implemented in regulated environments.

Vendor access must align with QA and change control processes

Industrial sites depend on ongoing remote support from machine builders, integrators, and maintenance partners.

Without structured governance, access can occur outside QA oversight, making it difficult to align with deviation management and change control procedures.

Data integrity depends on full traceability of system access

Pharmaceutical manufacturing relies on data integrity principles such as ALCOA+. Unstructured remote access can bypass validation boundaries, break traceability, and introduce undocumented system interactions or gaps in accountability.

AGGRAVATED BY COMPLIANCE DEMANDS

Remote access that supports compliance and data integrity requirements

Pharmaceutical manufacturing environments are governed by strict requirements for validated systems, controlled access, and data integrity. Structured OT secure remote access provides the technical foundation for enforcing these requirements across OT environments.

GxP frameworks require that all activities affecting production systems are controlled, documented, and attributable.

Guidance from global authorities such as PIC/S and MHRA reinforces the importance of secure, traceable access to computerized systems.

OT secure remote access supports these expectations by:

  • Enforcing unique user identification and authentication
  • Maintaining complete, time-stamped records of system access
  • Preventing uncontrolled or shared access to production systems

This ensures remote access aligns with global data integrity expectations.

Annex 11 requires that computerized systems be secure, access-controlled, and fully traceable.

OT secure remote access supports Annex 11 by:

  • Restricting access to authorized users and defined systems only
  • Enforcing role-based and time-limited permissions
  • Providing complete traceability of remote access sessions

This ensures that remote access does not compromise validated system boundaries.

FDA 21 CFR Part 11 requires that access to systems managing electronic records is secure, controlled, and attributable.

While Part 11 primarily applies to data systems, remote access must not introduce uncontrolled entry points.

OT secure remote access supports these expectations by:

  • Ensuring only authorized users can access production systems
  • Providing traceability of all remote sessions interacting with regulated systems
  • Eliminating shared or unmanaged access paths

This helps maintain the integrity of systems governed by Part 11.

Under NIS2, pharmaceutical manufacturers must implement cybersecurity risk management measures across OT environments.

OT secure remote access supports these requirements by:

  • Enforcing identity-based access control for all remote users
  • Providing continuous monitoring and logging of access activity
  • Supporting incident investigation through full session traceability

IEC 62443 defines best practices for securing industrial control systems used in production environments.

OT secure remote access aligns with these principles by:

  • Enforcing asset-level access instead of flat network connectivity
  • Limiting external access to specific production systems
  • Providing centralized visibility and logging of remote activity

This strengthens OT cybersecurity without impacting performance or validation.

Pharmaceutical facilities handling hazardous substances, such as active pharmaceutical ingredients (APIs) and chemical processes, may also be subject to safety frameworks such as Seveso (EU), COMAH (UK), PSM (US), and RMP (US).

While these frameworks focus on process safety, they depend on controlled and reliable operation of production systems.

OT secure remote access supports these environments by:

  • Restricting access to authorized users and defined systems

  • Ensuring full visibility of remote activity

  • Reducing the risk of unintended or unsafe interaction with production processes

Practical remote access use cases in pharmaceutical OT environments

Secomea’s Secure Remote Access solution can be seamlessly deployed across PLCs, SCADA, and MES systems, batch processing equipment, filling lines, and packaging systems in production sites – regardless of system age or vendor.

Controlled access to validated production systems

Time-limited, role-based access can be granted to defined machines or zones – ensuring validation boundaries are respected and maintained.

Secure vendor access aligned with QA processes

Engineers and external partners can diagnose and resolve issues quickly, reducing mean-time-to-repair while maintaining alignment with internal procedures.

Centralized governance across multiple plants

User management, policies, and session logs are centralized and consistent, while enforcement remains local within each facility.

Full session traceability for audits and inspections

All remote access sessions are tracked, logged, and recorded – supporting GxP compliance, FDA and EMA inspections, and internal QA audits.

HERE'S HOW WE DO IT AT SECOMEA

OT-native access architecture for validated production

Across pharmaceutical regulations, the requirement is clear: access to production systems must be controlled, attributable, and audit-ready.

OT secure remote access provides the technical foundation for meeting that expectation. Secomea supports regulated environments with:

Purdue Model-based OT security architecture showing secure remote access across industrial network layers. The diagram maps engineering workstations, HMIs, and PLCs at the zone level, a secure edge endpoint and data collector at the cell/area level, a low-latency encrypted gateway at the production level, and access management integrations with IAM, SIEM, and IoT platforms at the enterprise level. Secure remote users connect through an OT-native, agentless remote access client. IT manages identities and audit data, while OT controls least-privilege and just-in-time access for vendors and technicians.

Frequently asked questions

What is secure remote access in pharmaceutical manufacturing?

It is identity-based, controlled access to production systems ensuring all activity is attributable, traceable, and compliant.

How does it support GxP and data integrity requirements?

It ensures all system access is controlled, documented, and attributable, supporting validation and ALCOA+ principles.

Can remote access be used in validated systems?

Yes. It can be implemented without modifying control logic or affecting system validation.

How does it support Annex 11 and FDA requirements?

By ensuring secure, controlled, and traceable access to systems, supporting electronic records and computerized system requirements.

How is this different from VPN access?

VPNs provide broad, uncontrolled access. OT secure remote access enforces asset-level control with full traceability.

Can vendor access be controlled and audited?

Yes. Access is approved, time-limited, role-based, and fully traceable.
