Protecting the systems that keep essential services running.
Cybersecurity consulting for critical infrastructure and operational technology environments where digital security directly affects physical operations, safety and service continuity.
Critical Infrastructure & OT Security
Shelef Technologies provides cybersecurity consulting for critical infrastructure and operational technology environments, helping organizations identify and manage cyber risks across systems that support essential services and physical operations.
Operational Technology environments require a different security approach from conventional IT environments. Availability, safety, reliability and operational continuity must be considered alongside cybersecurity.
Our approach focuses on understanding the operational environment, identifying cyber risks and developing practical security measures that support both security and operational requirements.
Security for Operational Environments
OT environments can include Industrial Control Systems (ICS), SCADA systems, Distributed Control Systems (DCS), PLCs and other technologies responsible for monitoring and controlling physical processes.
We help organizations understand the security implications of connecting these environments to enterprise networks, remote-access platforms and external systems.
The objective is to improve security without compromising the availability and reliability of critical operations.
Protecting Energy & Industrial Assets
Production facilities, processing plants, pipelines and terminals rely on interconnected OT systems that must remain available under strict safety and regulatory requirements.
We assess segmentation, remote access, vendor connectivity and monitoring across these environments to reduce cyber exposure without disrupting operations.
