Securing the unpatchable in an age of AI-driven vulnerabilities

• AI is accelerating vulnerability discovery, leaving unpatchable operational technology (OT) systems at risk. Hoping for the best is not a viable anti-exploitation strategy.
• Deploying next-generation firewalls directly upstream allows for virtual patching through deep packet inspection. These systems scan incoming traffic to detect and block exploit attempts before they can impact the vulnerable device.
• The predictability of legitimate network connections to OT systems can be used to protect systems through micro-segmentation. This ensures that only a handful of authorized devices can communicate with the system, minimizing the attack surface.

AI-assisted code analysis is uncovering decades of technical debt. Every new patch removes a newly identified coding mistake.
