Legacy industrial automation systems threaten productivity and safety with aging components, unsupported software, and cybersecurity gaps. This series unpacks risks like unplanned downtime, data breaches, and non-compliance with modern standards (e.g., Industry 4.0, IIoT). Learn actionable strategies to assess vulnerabilities, prioritize upgrades, and migrate to secure, interoperable platforms—ensuring operational continuity, reduced maintenance costs, and future-ready scalability. Protect critical assets from obsolescence and cyberattacks while bridging the gap between aging machinery and smart automation demands.
