Southeast Asia is a high-value ICS/OT environment: rapid industrialization, mixed IT/OT estates, and geopolitical pressure that Western-centric TI often underweights.

​
Why SEA matters

Mixed IT/OT. Facilities across Thailand, Vietnam, Indonesia, Malaysia, and the Philippines blend modern Ethernet PLCs with legacy gear never designed for the internet. Supply-chain chokepoints. Energy, water, and manufacturing corridors serve global logistics. OT security maturity. Segmentation and OT monitoring remain uneven vs NA/EU norms.

​
Owned capacity

Reyhford’s owned honeypot capacity today is edge-sgp-001 (Singapore). Customer-enrolled sensors elsewhere expand coverage; confidence 100 typically needs multi-sensor corroboration (see Confidence Scoring).
