Industrial and critical infrastructure operators across Asia Pacific (APAC) are intensifying efforts to strengthen operational technology (OT) and industrial control systems (ICS) security. These initiatives respond to escalating threats, regulatory directives, and investment in proactive capabilities. Manufacturers and infrastructure organizations are increasingly implementing network segmentation, threat intelligence sharing, and incident response preparedness to transition from reactive to resilient cyber risk management.
Background
Ransomware and other cyber threats have surged across APAC, with attacks rising approximately 39% in 2023, significantly affecting manufacturing, real estate, and financial sectors, according to INTERPOL's regional threat assessment. This trend has drawn attention to OT vulnerabilities, particularly where legacy and SCADA (Supervisory Control and Data Acquisition) systems connect with enterprise networks. APAC governments have issued new regulatory policies in response: Japan's 2022 Cybersecurity Strategy mandates annual OT risk assessments in alignment with IEC 62443 standards, while China's Multi-Level Protection Scheme (MLPS) 2.0 guidelines require state-owned enterprises to allocate 7-10% of IT budgets to OT security. This has driven a 41% increase in domestic firewall deployments.
Details
Public-private collaboration on threat intelligence is expanding. In Hong Kong, cybersecurity firm Group-IB provided over 20 threat intelligence reports to law enforcement via the Cyber Security Action Task Force, exemplifying effective adversary-focused cooperation. Forrester reports that 79% of senior security leaders in APAC plan to increase threat intelligence budgets in 2026, outpacing planned investment in Europe and North America. Sectoral investment is rising, with Japan allocating more than US $3.8 billion in 2025 to public-private cybersecurity projects focused on ICS and critical infrastructure. The APAC OT security market is also expanding, with consulting and integration services expected to lead in 2025, and cloud-based OT security tools projected to grow at a 19.6% compound annual growth rate from 2025 to 2030.
Outlook
Regional trends indicate ongoing advancement in proactive OT defense. Greater segmentation, intelligence sharing, and incident response capability are set to enhance supply-chain resilience. The expansion of regulatory frameworks and sustained public-private cooperation are expected to support a transition from reactive OT risk management to anticipatory cyber resilience across APAC industries.
