FAQ

Common questions about OT security.

Clear answers to help you understand industrial cybersecurity, SCADA protection, and ICS security.

OT (Operational Technology) Security focuses on protecting industrial control systems, SCADA networks, and critical infrastructure from cyber threats. OT systems control physical processes in industries like manufacturing, energy, oil & gas, and water treatment. Unlike IT security, OT security prioritizes safety, uptime, and operational continuity alongside confidentiality and integrity. Our approach includes asset discovery, network segmentation, protocol security, controlled vulnerability testing, and continuous monitoring - all designed to protect operations without disrupting production or compromising safety.
