Federal Reports Sound Alarm on Legacy Industrial Systems
Federal assessments in the U.S. and Canada are shining a spotlight on the vulnerabilities of outdated industrial technologies, spurring investments in secure, durable computing solutions. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) and the Canadian Centre for Cyber Security (CCCS) issued sobering 2024 reports, warning that legacy operational technology (OT) systems often running on obsolete platforms like Windows XP or poorly isolated networks are prime targets for ransomware and other cyberattacks. The growing integration of OT with IT systems, amplified by the proliferation of Industrial Internet of Things (IIoT) devices, has created a volatile landscape of cyber risks.
Market data underscores the scale of the challenge. The global industrial cybersecurity market, valued at USD 19.00 billion in 2024, is expected to climb to USD 32.76 billion by 2033, with a compound annual growth rate (CAGR) of 6.24%, driven by advancements in artificial intelligence (AI) and machine learning (ML) for threat detection. Similarly, Credence Research projects the market to grow from USD 22,372 million in 2024 to USD 40,799.5 million by 2032, at a CAGR of 7.8%, fueled by the escalating frequency and complexity of attacks on critical infrastructure. In North America, which held a 36.5% share of the global market in 2024, the rising adoption of IIoT and cloud platforms is accelerating demand for robust cybersecurity measures.
Government Initiatives Tackle the Legacy Challenge
North American policymakers are responding with resolve. The U.S. Department of Energy’s Cybersecurity for Energy Delivery Systems (CEDS) program and Canada’s 2024 National Cyber Security Strategy Update are driving efforts to modernize OT systems. The U.S. White House’s 2023 National Cybersecurity Strategy prioritizes safeguarding critical infrastructure, while the NIST Cybersecurity Framework 2.0 (2024 draft) establishes rigorous standards for OT/IT integration. These initiatives send a clear signal: legacy systems must be upgraded to withstand modern threats.
But the road to modernization is fraught with obstacles. Many industrial control systems (ICS) in sectors like manufacturing, energy, and utilities are over two decades old, running on hardware and software long abandoned by vendors. Designed for durability rather than security, these systems struggle to interface with modern IoT devices or cloud-based platforms, creating exploitable gaps. According to CISA’s 2024 ICS Threat Report, North America saw a 35% surge in ICS-related vulnerabilities. A 2024 Deloitte Canada survey further reveals that 62% of manufacturing leaders view legacy infrastructure as their primary cybersecurity concern, a sentiment echoed across the continent.
The convergence of OT and IT systems, while essential for digital transformation, amplifies these risks. As Grand View Research notes, the growing reliance on interconnected systems and IIoT devices is a key driver of the industrial cybersecurity market, projected to reach USD 112.66 billion globally by 2033, with a CAGR of 9.9%. This underscores the need for solutions that balance innovation with security.
Lessons from High-Profile Breaches
Real-world incidents have crystallized the urgency. The 2021 Colonial Pipeline ransomware attack in the U.S. halted fuel distribution across the East Coast, exposing the fragility of interconnected OT systems. In Canada, 2023–2024 audits of Ontario’s energy sector identified outdated programmable logic controllers (PLCs) as high-risk, easily exploitable assets. CISA’s alerts to automotive and food processing plants have flagged vulnerabilities in legacy supervisory control and data acquisition (SCADA) systems, urging immediate action.
Some industries are heeding the call. Plants across North America are phasing out end-of-support systems, adopting industrial-grade Box PCs and long-lifecycle embedded solutions. Companies like Corvalent are leading the charge, offering ruggedized, U.S.-made industrial PCs designed for harsh environments. These platforms deliver extended service lifespans and robust firmware support, ensuring both reliability and compliance with evolving cybersecurity standards. For instance, a Midwest automotive facility recently upgraded its SCADA infrastructure with Corvalent’s systems, reducing downtime risks while aligning with federal guidelines.
These modernization efforts are bolstered by emerging technologies. As Credence Research highlights, the integration of AI and ML is revolutionizing threat detection, enabling real-time responses to cyber incidents. Meanwhile, the adoption of Zero Trust Architecture (ZTA) and cloud-based security solutions is reshaping industrial cybersecurity, offering scalable protection for complex environments.
Barriers to Progress
Despite these advances, significant challenges persist. Budget constraints and technical debt anchor many facilities to aging systems, as replacements often entail costly downtime. Integrating IoT devices into legacy setups can introduce compatibility issues, inadvertently creating new vulnerabilities. Commercial vendor’s short hardware lifecycles often just 3–5 years clash with industrial demands for 10–15 years of continuity. A shortage of OT cybersecurity experts, as reported by CyberSeek in the U.S. and ICTC Canada, further complicates the transition.
Yet, the market is poised for growth. MarketsandMarkets forecasts the North American industrial cybersecurity market to surpass USD 12 billion by 2030, with a CAGR of roughly 8%. This expansion is driven by demand for edge computing and long-lifecycle hardware, which offer cost-effective security enhancements. As IMARC Group notes, high-profile cyberattacks, like ransomware incidents, are raising awareness, pushing industries to prioritize cybersecurity investments.
Building a Cyber-Resilient Future
The way forward demands a paradigm shift. CISA, NIST, and CCCS are advocating for “security by design,” emphasizing embedded security chips and trusted boot mechanisms in industrial hardware. Hybrid architectures that combine edge computing with AI-driven threat monitoring are set to redefine plant modernization. Grand View Research highlights the rapid adoption of IIoT and cloud platforms, but stresses that these must be paired with robust measures like ZTA to counter evolving threats.
Corvalent stands at the forefront of this transformation. Their U.S.-manufactured, long-life industrial PCs provide end-to-end control over the component supply chain, ensuring security and compliance continuity. With extended lifecycle support and meticulous revision control, they offer a lifeline for industries navigating the shift from legacy to modern systems. As federal mandates loom potentially mandating modernization for critical infrastructure the imperative is clear: adopting secure, long-lifecycle computing platforms is not just strategic but essential for national resilience.
In a world where cyberattacks grow ever more cunning, the hum of that old programmable logic controller is no longer a sound of reliability it’s a warning. North America’s industrial sector stands at a crossroads, and the choice to modernize will shape the security of its critical infrastructure for decades to come.
