Uniquely among providers in the region, we integrate functional safety with OT cybersecurity, because in a modern plant a cyberattack on a safety system is itself a functional safety risk.
Arista Cyber delivers functional safety services that keep safety-critical industrial systems reliable, compliant, and protected across the entire safety lifecycle. From hazard identification to safety validation, our certified functional safety experts help UAE operators reduce risk, meet functional safety standards, and prove their systems perform when it matters most. Whether you need a single safety integrity level assessment or a complete functional safety management service, we work directly with your team on site across the Emirates and remotely.
Functional safety is the part of overall system safety that depends on protective systems operating correctly in response to their inputs. In industrial environments, it is what ensures a safety instrumented system, interlock, or emergency shutdown responds the way it should when a hazardous condition occurs, protecting people, equipment, and production.
Achieving it is not a one-time task. Industrial functional safety spans the full lifecycle of a safety system, from initial hazard analysis and functional safety requirements through design, implementation, validation, and ongoing management. Arista Cyber provides functional safety engineering services across every one of those stages for UAE operators, aligned to recognized functional safety standards including IEC 61511 for the process industries, IEC 61508 as the foundational standard, and ISO 26262 for automotive systems.
Systematic hazard and operability studies that identify risks and design safeguards, forming the foundation of your functional safety assessment.
Safety integrity level assessment that evaluates the exact level of risk reduction each safety function requires under IEC 61511.
Detailed functional safety requirements documentation that defines clear, testable safety goals for every safety-critical system.
Validation and verification that confirms safety instrumented systems meet both regulatory functional safety standards and real operational requirements.
A complete functional safety management service that tracks and governs the safety lifecycle of your systems, with audit-ready documentation.
Reliability, availability, maintainability, and safety analysis that optimizes system performance across all four dimensions.
A structured series of functional safety assessments and audits across the lifecycle to evaluate safety performance and close gaps.
Proof test procedures that validate safety system functionality under real operating conditions.
A cyberattack on a safety instrumented system is itself a functional safety failure. Most providers in the region treat functional safety engineering and OT cybersecurity as separate disciplines, and the gap between them becomes the exposure. Arista Cyber is a functional safety company that integrates both, aligning IEC 61511 with ISA/IEC 62443 so your safety systems are protected against random failure and deliberate attack alike. You can read more about our OT cybersecurity services and how they reinforce functional safety for UAE operators.
For operators across the Emirates in oil and gas, petrochemical, and power, this integrated approach closes a gap that safety-only and security-only providers leave open, and it aligns with the direction the UAE is taking on critical infrastructure protection.
Functional safety is not a single task; it is a lifecycle. Each of our services maps to a specific stage of the IEC 61511 safety lifecycle, so your safety systems are covered from initial hazard analysis through operation and modification.

Yes. Our certified functional safety consultants deliver services aligned to IEC 61508 as the foundational standard and IEC 61511 for process industry safety instrumented systems, along with ISO 26262 for automotive and ISA/IEC 62443 where safety and cybersecurity intersect.
A safety integrity level assessment determines the level of risk reduction each safety function must deliver to bring risk to a tolerable level. Arista Cyber provides both SIL determination and SIL verification, so your safety instrumented systems are not only assigned a target but confirmed to meet it.
Our functional safety engineering services cover HAZOP and HAZID studies, SIL assessment and determination, safety requirement specification, safety validation and verification, RAMS studies, functional safety management service and documentation, functional safety assessments (FSA 1 to 5), and proof test procedures, all aligned to IEC 61511 and IEC 61508.
Functional safety focuses on preventing systems from failing in ways that cause harm, such as safety instrumented systems, interlocks, and emergency shutdown systems. Cybersecurity focuses on preventing unauthorized access or attacks. Arista Cyber integrates both, since a cyberattack on a safety system is itself a functional safety risk. This is the core of how we approach IEC 62443 compliance.
In OT environments, a safety system failure is not just a compliance issue; it can mean unplanned shutdowns, equipment damage, or harm to personnel. As UAE industry expands across oil and gas, petrochemical, and energy, and as OT and IT systems converge, functional safety ensures protective systems respond correctly when something goes wrong.
