Industrial Control System (ICS) Security Market

The industrial control system (ICS) security market in the energy & power vertical is projected to grow from USD 7.74 billion in 2025 to USD 17.12 billion by 2030 at a compound annual growth rate (CAGR) of 17.2% during the forecast period. In October 2022, Tata Power reported a cyberattack that affected its IT systems and raised concerns about access controls linked to power operations. In October 2020, a major power outage in Mumbai exposed weaknesses in grid isolation and system visibility. These incidents showed the financial and operational impact of cyber-related downtime. As a result, power operators across Asia Pacific are adopting continuous monitoring and clearer incident response practices to meet rising regulatory expectations and reduce disruption risks.

What is Industrial Control System (ICS) Security?

According to MarketsandMarkets, “ICS security refers to the protection of industrial control systems that manage critical infrastructure like power plants, manufacturing lines, and water systems. It involves safeguarding hardware, software, and network components from cyber threats. The goal is to ensure operational continuity, safety, and data integrity. ICS security combines traditional IT practices with OT-specific protection. It also addresses unique challenges like legacy systems, limited downtime, and real-time operational requirements”.
