For a long time, cybersecurity was viewed as a “nerds vs. hackers” software battle. If a system was hacked, the worst outcome usually meant losing some data or a few credit card numbers. Today, however, the stakes have moved far beyond the digital world and into the physical one.

Experts note that modern cyberattacks are no longer limited to stealing files. Increasingly, hackers are targeting critical infrastructure – shutting down power grids, interrupting hospital treatments, and halting factory production lines.

Roger Lvin, CEO of Hitachi Digital Services and Executive Chairman of Hitachi Cyber, has been vocal about this shift. According to him, cyber risk can no longer be treated as an issue solely for the IT department. “Because our physical world – like water systems and trains – is now connected to the internet, a digital glitch can trigger a physical disaster,” he said.

The Old Way vs. the New Way

Old Mindset: Focus on ticking compliance boxes and protecting digital records or spreadsheets.

New Reality: Focus on ensuring that critical systems keep running—keeping the lights on and machines operational.

Artificial Intelligence Is Fueling the Arms Race

Artificial Intelligence is rapidly intensifying the cybersecurity battle.

Hackers are now using AI to:

●     Create more sophisticated scams

●     Automate attacks at massive speed

●     Identify vulnerabilities faster than human attackers

At the same time, organizations are using AI to detect and respond to threats in real time.

However, AI is not a magic solution. Experts noted that, if companies lack strong security strategies, AI can actually accelerate failure. This risk is especially severe in environments like power plants and industrial facilities, where a split-second AI error could damage physical equipment.

Protecting the “Physical Internet” (OT)

The technology that controls machines in factories, power plants, and infrastructure is known as Operational Technology (OT).

For years, OT systems were considered safe because they were isolated and not connected to the internet. That assumption no longer holds true.

‘Now they are connected, and they have become massive targets,’ Lvin says.

Hackers understand that shutting down a manufacturing line or infrastructure system gives them far more leverage than stealing emails. As a result, cybersecurity now requires collaboration between engineers who operate machines and security teams who protect networks.

Simply put: you cannot secure systems you don’t fully understand.

Why India Is Emerging as a Cybersecurity Powerhouse

The global talent landscape is also evolving. India, once known primarily for IT support services, is increasingly becoming a center for advanced cybersecurity and AI expertise. Organizations around the world are turning to Indian engineers to help secure complex industrial environments and defend against sophisticated cyber threats.

The Bottom Line for Business Leaders

Industry experts emphasize that leaders must rethink cybersecurity strategies in three key ways:

CEO Accountability

Cybersecurity is no longer just a technology issue—it is a core leadership responsibility.

Resilience Over Perfection

No organization can prevent every attack. The real goal is building systems that can withstand attacks and continue operating.

Invest in People

Security tools and AI platforms are important, but companies ultimately need skilled professionals who understand both technology and real-world operations.

The Bigger Picture

Cybersecurity is no longer a background IT task—it has become a critical foundation for economic stability. The consequences of failure are no longer limited to stolen passwords or leaked files. The real risk today is disrupted systems, damaged infrastructure, and a loss of public trust.
