Critical Infrastructure Protection Market
Market Size and Growth
The global critical infrastructure protection market is growing at a high CAGR during the forecast period (2024-2031).
Key Development:
United States: Recent Critical Infrastructure Protection Developments
✅ In December 2025, Cybersecurity and Infrastructure Security Agency (CISA), National Security Agency (NSA) and the Canadian cyber agency issued a joint advisory warning that state‐linked actors have deployed a sophisticated malware called BRICKSTORM targeting critical‐infrastructure and IT networks urging operators to immediately assess systems, apply mitigation and report incidents.
✅ In December 2025, cybersecurity investigators confirmed that BRICKSTORM has compromised systems using virtualization platforms (notably VMware vSphere/vCenter), allowing attackers to steal credentials, maintain long‐term access, and potentially enable sabotage of sensitive infrastructure.
✅ In early December 2025, the advisory included detailed indicators of compromise (IOCs) and detection signatures giving critical infrastructure owners concrete guidance to audit environments, identify breaches, patch vulnerabilities, and harden network segmentation.
✅ In October-November 2025, agencies issued broader alerts highlighting that supply‐chain exploits and rapidly evolving malware including AI‐assisted tactics increasingly threaten industrial control systems (ICS), urging adoption of zero‐trust architectures and enhanced cyber hygiene across utilities, transport, and energy sectors.

Japan: Recent Critical Infrastructure Protection Developments
✅ In November 2025, Ministry of Economy, Trade and Industry (METI), together with Industrial Cyber Security Center of Excellence (ICSCoE) and partner agencies from the U.S. and EU, hosted the JP‐US‐EU Industrial Control Systems Cybersecurity Week (Nov 18-21, 2025) in Tokyo bringing nearly 200 practitioners for hands‐on ICS cybersecurity training and strengthening cross‐border cooperation on infrastructure protection.
✅ In November 2025, as part of the cybersecurity week and broader policy push, Japan reaffirmed focus on building capacity among government and private‐sector operators of critical infrastructure emphasizing resilience, incident readiness, and coordination across nations in Indo‐Pacific region.
✅ In October 2025, Japan held the 18th ASEAN-Japan Cybersecurity Policy Meeting (Oct 8-9) in Tokyo, where Japanese ministries and ASEAN partners discussed strengthening cybersecurity collaboration, critical information infrastructure protection, public-private partnerships, and supply‐chain security for critical systems.
✅ In the same period (Oct-Nov 2025), Japanese cybersecurity institutions including private think‐tanks and newly merged research bodies stepped up efforts to unify cyber‐defense strategy, particularly focusing on securing software supply‐chains, industrial controls, and promoting cyber‐resilience across infrastructure sectors.
Recent Mergers and Acquisitions :
United States: Recent M&A Developments in Infrastructure & Cybersecurity
✅ In November 2025, Palo Alto Networks agreed to acquire Chronosphere a next‐gen observability platform for US $3.35 billion to strengthen resilience, monitoring and security capabilities for AI‐era infrastructure and cloud‐native environments.
✅ Also in November 2025, LevelBlue (formerly AT&T Cybersecurity) completed the acquisition of Cybereason a cybersecurity firm specializing in endpoint detection and response – expanding its managed detection / response and threat‐monitoring services to better serve critical infrastructure clients globally.
✅ In October-November 2025, multiple smaller security‐service and cybersecurity‐tool providers were consolidated through deals (e.g., acquisitions of firms specializing in identity security, threat detection, application‐security, and risk quantification) reflecting growing demand for robust cyber‐defense across critical infrastructure, industrial and enterprise environments.
✅ In late 2025, several acquisitions by firms combining OT/IT cybersecurity, cloud observability, and identity management reflect a shift toward integrated infrastructure‐security models, anticipating that critical infrastructure (utilities, grid, cloud data centers) will require unified protection spanning network, identity, cloud, and operational‐tech layers.

Japan: Recent M&A / Acquisition‐type Moves in Infrastructure & Cybersecurity
✅ In September 2025, Mitsubishi Electric Corporation announced it will acquire Nozomi Networks a U.S.-based leader in OT / IoT / industrial‐cybersecurity solutions via a reverse‐triangular merger (approx. US $883 million), strengthening its capacity to deliver “one‐stop” OT security solutions for industrial and social‐infrastructure sectors (power grids, rail, manufacturing, etc.).
✅ Under the terms, Nozomi Networks will become a wholly‐owned subsidiary of Mitsubishi Electric (expected within 2025), allowing integration of Nozomi’s OT/IoT cyber‐defense tools into Mitsubishi’s broader industrial offerings a strategic move to improve resilience of critical infrastructure in Japan and globally.
✅ This acquisition is described as one of the largest in industrial‐cybersecurity/OT security space signalling strong prioritization by Japanese industrial conglomerates on upgrading protection for infrastructure systems vulnerable to cyber‐physical threats, as utilities, manufacturing and infrastructure digitalization ramp up.
✅ Through this deal, Mitsubishi intends to leverage data and context from OT/IoT environments (industrial/factory/utility operations) to build more effective cyber‐defense and monitoring services blending operational‐technology security with AI/data-driven threat detection, boosting resilience of critical systems.
