Overview
Industrial Control Systems (ICS) and Operational Technology (OT) environments in Turkey face growing cybersecurity threats. Critical sectors including manufacturing, energy, oil & gas, water treatment, transportation, and smart infrastructure depend heavily on secure ICS/OT systems. Cyber incidents can cause operational downtime, safety hazards, financial losses, and regulatory non-compliance.
IEC 62443 is a globally recognized cybersecurity standard for ICS/OT environments. It provides a structured framework for risk assessment, system security requirements, secure development lifecycle, and continuous cybersecurity management. Aligning with IEC 62443 ensures compliance with Turkish regulations, protects critical infrastructure, and demonstrates cybersecurity due diligence.
Cyberintelsys, a CREST-accredited cybersecurity company, delivers comprehensive IEC 62443-aligned Vulnerability Assessment (VA) and Penetration Testing (PT) services in Turkey. Our services help industrial organizations identify, assess, and remediate cybersecurity risks while maintaining operational safety and business continuity.
Importance of VA/PT for IEC 62443
ICS/OT systems differ from traditional IT networks, often including legacy devices, proprietary protocols, and safety-critical processes that cannot tolerate downtime. Vulnerabilities may exist in PLCs, HMIs, SCADA servers, industrial networks, remote access systems, and IT-OT integration points.
Detect critical vulnerabilities impacting safety, availability, or process integrity.
Ensure compliance with IEC 62443 standards.
Maintain operational continuity without disrupting production.
Mitigate safety risks from potential cyber incidents.
Build confidence among regulators, partners, and clients.
Partnering with a CREST-accredited provider like Cyberintelsys ensures ethical, standardized, and globally recognized testing practices.
Cyberintelsys CREST-Accredited VA/PT Approach
Our IEC 62443 assessment methodology combines technical rigor, regulatory alignment, and ICS/OT expertise.
