As industrial systems become more connected, cybersecurity risks to OT (Operational Technology) and ICS (Industrial Control Systems) grow. One crucial but often overlooked defense strategy is dark web monitoring, which helps detect threats before they impact critical infrastructure.

The dark web serves as a marketplace where cybercriminals trade stolen data, credentials, and exploits. For sectors like energy, manufacturing, water, and transportation, monitoring these underground forums provides early warnings of potential attacks, such as leaked credentials or discussions about targeting ICS/SCADA systems. Reports have shown that cybercriminals frequently auction access to energy companies, putting OT environments at risk.

Dark web monitoring tools scan hidden forums and databases for company-specific data, such as leaked VPN credentials or proprietary software code. Early detection allows organizations to take proactive steps, like updating access controls and strengthening cybersecurity measures.

However, dark web monitoring should be part of a comprehensive defense-in-depth strategy, alongside intrusion detection systems, network segmentation, and employee training. Successful implementation requires defining monitored data, setting up alerts, integrating findings into incident response plans, and coordinating with IT and compliance teams.

As threats to industrial systems rise, dark web monitoring acts as an early warning system, helping organizations respond swiftly and maintain operational security.
