FUNCTIONAL SAFETY SERVICES
FUNCTIONAL SAFETY
DIGITIZATION
Move your functional safety program from static documents to connected, auditable, and actionable digital systems. Reduce manual effort, improve data integrity, and give your teams real-time visibility into safety performance across the lifecycle.
The functional safety lifecycle generates a large and growing volume of documentation. HAZOP records, SIL determination reports, LOPA worksheets, safety requirement specifications, SIL verification calculations, validation records, proof test logs, management of change records, and FSM audit trails accumulate across every project phase and continue growing through the operational life of every safety instrumented system under an organization's responsibility.
In most organizations, this documentation exists across a fragmented landscape: spreadsheets, shared drives, PDF archives, paper records, and proprietary engineering tools that do not communicate with each other. Traceability between a proof test result and the SIL verification assumption it is designed to validate requires manual cross-referencing across multiple systems. A management of change request requires searching through several document repositories to establish the current safety baseline. An FSA preparation exercise becomes a document retrieval and reconciliation project before any assessment work can begin.
The cost of this fragmentation is not just administrative. It introduces a real safety risk. When the current status of a SIF's proof test compliance is not immediately visible, overdue tests go unnoticed. When the management of change records is not linked to the SIL verification calculations for the affected function, change impacts are assessed without full information. When safety lifecycle documentation cannot be queried and cross-referenced efficiently, the organizational knowledge embedded in it degrades over time as staff change and institutional memory is lost.
Functional safety digitization addresses these problems by connecting the documentation, data, and workflows of the safety lifecycle into structured digital systems that support better decisions, faster compliance demonstration, and more effective ongoing safety management.
Digitization of the functional safety lifecycle is not simply scanning paper documents or migrating spreadsheets to a cloud platform. It is the structured implementation of digital tools and connected data models that reflect the architecture and requirements of IEC 61511 and support the people responsible for safety across every lifecycle phase.
Functional safety digitization covers several distinct but interconnected areas:
Digital Safety Lifecycle Documentation
Replacing static document repositories with structured, version-controlled digital records for every safety lifecycle deliverable: HAZOP records, SIL determination reports, SRS documents, design verification records, validation records, FSM plans, and FSA reports. Digital lifecycle documentation enables traceability between deliverables, version management, review and approval workflows, and audit trail generation without manual effort.
Connected SIF Register and Safety Data Management
A structured digital SIF register that connects each Safety Instrumented Function to its SRS requirements, SIL target, SIL verification record, proof test procedure, proof test schedule, and current compliance status. A connected SIF register gives safety engineers, operations managers, and FSM coordinators a single point of reference for the status of every safety function under their responsibility, replacing the manual reconciliation of information held across separate documents and systems.
Proof Test Management and Compliance Tracking
Digital proof test management systems that schedule tests against the intervals required by SIL verification assumptions, issue notifications when tests are approaching or overdue, capture test results against defined acceptance criteria, flag failures for follow-up action, and generate compliance records automatically. Proof test management digitization eliminates the manual tracking burden that leads to overdue tests going unnoticed and test records being incomplete or inconsistent between cycles.
Digital Management of Change
A structured digital MOC process that links change requests to the safety baseline of the affected systems, prompts the required safety impact assessment, routes approvals to the right authorities, and maintains a complete, queryable record of every change made to a safety-related system since commissioning. Digital MOC ensures that no change reaches implementation without a documented safety review and that the cumulative effect of multiple changes on the safety case is visible.
Safety Performance Dashboards and Reporting
Real-time visibility into functional safety program performance through structured dashboards that surface proof test compliance rates, open non-conformances, overdue FSM actions, management of change activity, and SIL achievement status across all safety instrumented systems. Digital safety performance reporting replaces periodic manual report generation with continuous visibility that supports proactive management rather than reactive response.
Integration with Engineering and OT Systems
Connection of the functional safety data model to the engineering information systems and OT infrastructure that surround it: plant asset registers, maintenance management systems, DCS and SIS configuration management tools, and OT network monitoring platforms. Integration eliminates the data re-entry, version inconsistency, and information silos that create both administrative burden and safety risk in conventionally managed programs.
The digitization of functional safety programs introduces new considerations that do not arise in paper-based systems. Digital safety lifecycle tools, connected SIF registers, and proof test management platforms are themselves software systems that hold safety-critical data and support safety-critical decisions. Their integrity, availability, and protection from unauthorized modification are not optional attributes.
A connected functional safety management platform that can be accessed by an unauthorized party, that lacks adequate backup and recovery capability, or that allows safety lifecycle records to be modified without an audit trail, is not a safer alternative to paper-based management. It is a different and potentially larger risk.
Arista Cyber approaches functional safety digitization with this reality at the center of the engagement. Every digital system we recommend or implement for safety lifecycle management is assessed for its cybersecurity posture alongside its functional capability. Data integrity controls, access management, audit trail requirements, backup and recovery, and integration security are part of the digitization design, not an afterthought.
Our functional safety digitization work is structured in alignment with:
- IEC 61511-1: Functional safety lifecycle requirements, which define the documentation, traceability, and management system requirements that digitization must support and maintain
- IEC 61511-1 Clause 6: FSM Plan requirements for documentation control, configuration management, and management of change, which digital systems must reflect and operationalize
- IEC 61508 Part 3: Software lifecycle requirements applicable to safety management software tools used in the functional safety lifecycle
- ISA/IEC 62443: Security requirements for industrial automation and control systems, applied to the OT-connected digital platforms that support functional safety management
- IEC 27001: Information security management principles applied to the protection of safety lifecycle data and the systems that hold it
We approach functional safety digitization as an engineering and management challenge, not a software implementation project. The goal is a digital program that genuinely improves safety management outcomes, not a technology deployment that adds complexity without corresponding benefit.
Current State Assessment
We assess the current state of the functional safety program: the documentation landscape, the tools in use, the data quality and completeness, the manual processes that create the most burden or the greatest risk of error, and the organizational structure and competency context in which the digital program must operate. The current state assessment defines what needs to be digitized, in what order, and to what standard.
Digital Architecture and Tool Selection
We define the digital architecture for the functional safety program, identifying the tools, platforms, and integration points required to support the target state. Tool selection is based on functional fit, IEC 61511 alignment, cybersecurity posture, integration capability with existing engineering and OT systems, and the practical ability of the organization to adopt and maintain the solution. We are tool-agnostic: our goal is the right solution for the client, not a preferred vendor.
Implementation and Data Migration
We support the implementation of selected digital tools, including configuration to reflect the client's safety lifecycle structure, migration of existing safety lifecycle data into the new environment, integration with connected engineering and OT systems, and validation that the implemented system correctly supports the required safety lifecycle workflows. Implementation is conducted in phases, prioritizing the areas of greatest current risk or administrative burden.
Training, Handoff, and Ongoing Support
We develop training for the teams who will use and maintain the digital safety program, covering both the tool capabilities and the functional safety management principles they are designed to support. We conduct a structured handoff that confirms the organization is capable of operating and evolving the digital program independently, and we provide ongoing support for program optimization as the organization's needs develop.
- Real-time visibility into the compliance status of every Safety Instrumented Function, including proof test scheduling, overdue test alerts, and open non-conformance tracking
- A connected, traceable safety lifecycle record that links every SIF to its hazard origin, SIL target, design basis, validation evidence, and current operational status without manual cross-referencing
- A controlled, auditable management of change process that ensures every modification to a safety-related system is assessed, approved, and documented before implementation
- Significant reduction in the administrative burden of FSM audit preparation, FSA evidence assembly, and regulatory reporting, because the required documentation is structured, version-controlled, and queryable rather than scattered across multiple repositories
- Improved organizational resilience to staff turnover, because safety program knowledge is held in structured digital systems rather than in individuals who may leave
- A cybersecurity-aware digital safety program that protects the integrity of safety lifecycle data and the systems that hold it, aligned to ISA/IEC 62443 and IEC 27001 principles
- Current state assessment report identifying digitization priorities, data quality gaps, and risk areas in the current safety program management approach
- Digital architecture specification defining the tools, platforms, integration points, and data model for the target digital safety program
- Configured and validated digital safety management environment, including SIF register, proof test management, MOC workflow, and safety performance dashboards
- Data migration package transferring existing safety lifecycle documentation and data into the new digital environment
- Cybersecurity assessment of the digital safety program architecture, with recommendations for data integrity controls, access management, and integration security
- Training materials and handoff documentation for the teams responsible for operating and maintaining the digital program
Most organizations offering functional safety digitization are either functional safety specialists who treat cybersecurity as an afterthought or technology integrators who understand the software but not the safety lifecycle requirements the software must support. The result is digital programs that are technically implemented but either non-compliant with IEC 61511 or inadequately protected against the cybersecurity risks their connectivity introduces.
Arista Cyber sits at the intersection of functional safety and OT/ICS cybersecurity. That positioning is not incidental to functional safety digitization. It is the defining capability that makes our approach different.
- Functional safety expertise across the complete IEC 61511 lifecycle, ensuring that every digital tool and workflow we implement reflects the standard's actual requirements rather than a simplified interpretation
- OT/ICS cybersecurity competence applied to the protection of the digital safety program infrastructure, ensuring that the digitization investment strengthens rather than compromises the safety case
- Tool-agnostic advisory that prioritizes the right solution for the client's safety programme, operational context, and existing technology landscape
- Practical implementation experience that accounts for the organizational, operational, and data quality realities of existing safety programmes, not just the ideal-state target
- Deep operational experience across high-consequence sectors, including oil and gas, energy, pharmaceuticals, and process manufacturing
We do more than implement software. We help organizations build digital functional safety programs that improve safety outcomes, reduce management burden, and give leadership genuine confidence in the performance of the systems that protect their people and assets.
