Legacy equipment has been linked to cyberattacks against utility organisations. It’s a problem well beyond utilities: old, unsupported hardware and software no longer receive security updates, leaving known holes wide open for attackers to walk through.
The Foresight take
End-of-life kit is a security liability, not just an operational one. Once a vendor stops issuing patches, every newly discovered flaw in that device is permanent — and attackers actively hunt for exactly these forgotten systems.
Keep a live inventory of your hardware and software, track end-of-support dates, and plan replacements before they become risks. Where legacy systems can’t be retired yet, isolate them behind segmentation and tight controls. We help clients build and manage that lifecycle.
