OT & IoT Security: vendors and distributors in Southeast Asia
Products built for industrial control systems, building systems, medical devices and other equipment that cannot run a normal security agent: passive asset discovery and monitoring, industrial firewalls, secure remote access for maintenance, and one-way gateways between plant and enterprise networks. Buyers are usually plant and engineering teams working with IT security.
What is sold under this label
- OT asset visibility and threat detection
- Passively reads industrial protocols to list every controller and device on the plant network and flag abnormal behaviour.
- Industrial firewalls and segmentation
- Ruggedised firewalls that understand industrial protocols and separate plant zones from each other and from IT.
- Data diodes
- Unidirectional gateways that let data leave a protected network but make traffic in the other direction physically impossible.
- Secure remote access for OT
- Lets vendors and engineers reach specific equipment for maintenance, with approval, least privilege and session recording.
- IoT and medical device security
- Discovers and profiles unmanaged devices — cameras, building systems, medical equipment — that cannot run a security agent.
- Removable media and file sanitisation
- Kiosks and gateways that scan USB drives and files before they enter an isolated network.
