Overview
Operational Technology (OT) and Industrial Control Systems (ICS) in Turkey face increasing cybersecurity threats. Critical sectors such as energy, manufacturing, transportation, and smart infrastructure require robust protection of ICS/OT systems to prevent operational disruptions, safety hazards, and regulatory non-compliance.
IEC 62443 provides a structured framework for ICS/OT cybersecurity, covering risk assessment, system security requirements, secure development lifecycle, and continuous monitoring. Conducting a security gap analysis helps organizations identify vulnerabilities and maintain compliance with international standards.
Cyberintelsys, a CREST-accredited cybersecurity provider, delivers detailed security gap analysis and compliance verification aligned with IEC 62443 for organizations in Turkey.
Importance of Security Gap Analysis
ICS/OT systems may include legacy devices, proprietary protocols, and high-availability processes. Security gaps can exist in PLCs, HMIs, SCADA servers, industrial networks, and IT-OT integration points.
Identify gaps impacting operational integrity, safety, or availability.
Ensure regulatory compliance with IEC 62443 standards.
Maintain operational continuity while mitigating vulnerabilities.
Strengthen overall cybersecurity posture.
Build confidence with regulators, partners, and stakeholders.
Cyberintelsys CREST-Accredited Gap Analysis Approach
Our approach combines technical evaluation, regulatory alignment, and practical ICS/OT expertise.
