Engineering-led functional safety consulting in Saudi Arabia, aligned to IEC 61511 and ISO 26262.
Arista Cyber provides functional safety consulting in Saudi Arabia that helps industrial operators keep their safety-critical systems reliable, compliant, and audit-ready. As a functional safety company serving Saudi oil and gas, petrochemical, energy, and manufacturing operations, we deliver industrial functional safety engineering services across the entire safety lifecycle, from hazard identification through safety integrity level determination, verification, and validation. Our certified functional safety consultants work to the requirements of IEC 61511, IEC 61508, and ISO 26262, so your safety instrumented systems deliver the risk reduction they were designed for. Uniquely among providers in the Kingdom, we integrate functional safety with OT cybersecurity, an approach that matters more in Saudi Arabia than almost anywhere, because the Kingdom is where the world first saw a cyberattack designed to defeat a safety instrumented system.
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 Saudi 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 program, we work directly with your team on site across the Kingdom 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 Saudi 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.
Functional safety management documentation that tracks and governs the complete safety lifecycle of your systems.
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.
Saudi Arabia holds a unique place in the history of industrial cybersecurity. It was at a Saudi petrochemical facility that attackers first deployed malware specifically designed to defeat a safety instrumented system, targeting the very interlocks that stand between normal operation and a catastrophic event. That incident forced the global functional safety community, and the IEC 61511 and IEC 61508 committees, to accept a new reality: a safety instrumented system must now be protected against deliberate cyberattack, not only against random failure.
This is exactly why Arista Cyber integrates functional safety and OT cybersecurity rather than treating them as separate disciplines. We align IEC 61511 with ISA/IEC 62443 so your safety systems are protected against both failure and attack. You can read more about our OT cybersecurity services and how they reinforce functional safety for Saudi operators. For plants across the Kingdom, this integrated approach closes a gap that safety-only and security-only providers leave open.
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.

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.
Since a cyberattack on a safety instrumented system is itself a safety risk, modern functional safety in Saudi Arabia must consider cybersecurity. Our work aligns IEC 61511 with ISA/IEC 62443 and supports the intent of the Kingdom's NCA Operational Technology Cybersecurity Controls.
