As threats evolve, outdated IT playbooks won’t protect OT. Learn how leaders are building cyber resilience now.
Critical infrastructure is not only under threat, but it has been and is under test. Whether in power grids and water treatment plants or during transport, the convergence of information technology (IT) and operational technology (OT) has generated efficiency openings, but it has also manifested stark and painful gaps in terms of cybersecurity. Attackers do not require physical access or high-level insider knowledge. One neglected OT endpoint or a badly-patched industrial controller is all they require to take out the critical services.

The convergence challenge we can’t ignore
In the past, IT and OT were siloed. Now they are bonded design. Smart manufacturing facilities, networked utility grid, and autonomous systems thrive on operational environment real-time data. However, such a union broadens the threat sector as well. The conventional IT controls are not designed to address the unique limitations of OT, including legacy systems, real-time operations requirements, and safety-critical operations. The upshot: the security of America and critical infrastructure has proved to be highly more complex and vulnerable.
In the case of C-suite business leaders, IT/ OT security is no longer a back-office problem in industrial settings but a business must-have. Downtime can no longer be defined in minutes; it is now defined in terms of money, of reputations, and national security issues.
The adversaries are evolving faster than defenses
Infrastructure is also being maliciously targeted by cybercriminals and nation-state actors. In particular, OT systems are targeted by such sophisticated malware as TRITON and Industroyer. In 2024 alone, more than 60 percent of breaches of critical infrastructure came via OT access points, hence mainly via third-party vendors.
The next thing that is changing the game is the fact that AI is used in reconnaissance and automating attacks. This allows malicious actors to identify vulnerabilities and conduct precision-targeted attacks with the ability to scan as well as map the OT environment quickly. Such attacks have moved beyond theory as the operational reality. Protection of infrastructure needs to move at the same pace.
Outdated models won’t protect tomorrow’s infrastructure
Relying on patchwork compliance or traditional IT playbooks doesn’t cut it anymore. Regulatory reporting and routine audits create a false sense of security. Compliance may tick boxes, but it does not secure resilience.
What is called for instead is a change in approach—toward converged, real-time cyber defense frameworks optimized for hybrid IT/OT environments. Top organizations are implementing compliance automation, AI-driven anomaly detection, and asset-level visibility throughout operational networks.
Strategic priorities for future-ready leaders
To stay ahead of escalating threats, executives must focus on:
- Real-time compliance monitoring for dynamic threat visibility
- Micro-segmentation of networks to contain lateral movement
- Cloud-based compliance tools for scalable protection
- KYC automation and AML technology to secure financial operations within critical infrastructure
- Strategic investment in cross-functional teams and digital transformation in compliance
RegTech solutions for banks and financial institutions already demonstrate how digital compliance solutions can reduce the cost of compliance while enhancing governance. These principles are now migrating into the OT space, where risk management in finance parallels industrial threat modeling.
Cyber resilience needs more than compliance
It’s time to reframe cybersecurity strategies for critical infrastructure. Compliance is foundational, but it can’t be the ceiling. C-suites need to infuse security thought into all layers of operations, from purchasing to predictive servicing. Data governance, AI-based threat intelligence, and cross-industry collaboration will be the markers of future success.
Lead or lag—the decision is now
IT/OT security isn’t a defensive move—it’s a competitive one. Organizations that are ahead in infrastructure protection will earn trust, achieve uptime, and become known as robust market leaders.
