While OT Managed Services may share a foundation with IT, the physical risks of critical infrastructure require a fundamentally different approach. Parasyn provides high-governance OT management designed for the Brownfield Dilemma, ensuring legacy assets remain safe, secure, and evolution-ready through validated engineering protocols.

At Parasyn, we provide Governance-Led OT Operations. We move beyond the “break-fix” mentality of traditional support to offer a structured engineering framework. By integrating Management of Change (MoC), IEC 62443 security standards, and staged lifecycle evolution, we ensure your systems don’t just stay online—they remain safe, compliant, and evolution-ready.

Staged Engineering & Lifecycle Evolution

We treat your OT environment as a living asset. Our MSA manages the continuous evolution of your system to prevent technical debt from compromising safety.

  • Controlled Modernization: Phased hardware and software refreshes engineered to eliminate process downtime.
  • Obsolescence Management: Proactive roadmapping of end-of-life PLCs, HMIs, and networking gear with validated migration paths.

Managed System Change & Configuration Integrity

Unmanaged change is the leading cause of OT downtime. We apply rigorous Management of Change (MoC) protocols to every engineering adjustment.

  • Configuration Governance: Centralized version control and auditing for all PLC logic, SCADA telemetry, and industrial network settings.
  • Disaster Readiness: Automated, verified backups of all industrial configurations, ensuring a “Return to Known-Good State” in minutes, not days.

Continuous Security & Standards Compliance

Security in OT is a functional safety requirement ($SIL$). We align your operations with the IEC 62443 framework and Australia’s SOCI Act requirements.

  • Vulnerability Governance: We assess vulnerabilities against process impact. If a patch risks process stability, we engineer compensatory controls (Zones & Conduits) to shield the asset.
  • Compliance Evidence: Continuous documentation and auditing to meet high-governance regulatory mandates for water, transport, and energy sectors.

Operational Support: The SLA-Backed Execution Engine

While our MSA focuses on strategy and governance, we provide a robust framework for daily operational needs. This is the “Safety Net” that ensures your team is never left without expert engineering support.

High-Performance Service Level Agreements (SLA)

Our traditional support is governed by the same transparency found in our SLA Brochure. We offer a tiered response model that guarantees accountability for every request.

  • Priority-Based Response: From P1 emergency restorations to P4 standard engineering requests.
  • Mean Time to Restore (MTTR): We focus on the speed of process recovery, not just the initial response.
  • OT-Specialist Service Desk: Direct access to engineers who understand industrial protocols and site-specific safety standards.

Core Support Activities

  • Industrial Break-Fix: Rapid troubleshooting of SCADA, PLC, and networking faults.
  • Request Fulfillment: Standardised execution of moves, adds, and changes (MACs).
  • Site Knowledge Management: Maintenance of site-specific “Engineering Standards” so that every intervention is consistent with your original design philosophy.
