A programmable logic controller (PLC) is a device designed for controlling manufacturing processes. Because they are highly reliable and easy to program, they are found in almost every manufacturing environment. As the modernization of these environments continues, and operational technology spreads everywhere, more PLCs are implemented every day.

As OT devices are becoming more and more network-connected, they can become a potential weak spot in your environment that can leave you at risk of downtime or cyberattacks. However, it also means they can be scanned and analyzed, giving you complete visibility and control of your OT estate, and allowing you to make sure that everything is protected by the latest safety protocols.

Lansweeper scans PLC information using the Lansweeper OT scanner, which leverages specialized protocols to speak the same language as your devices. Alternatively, certain information can also be retrieved from your PLCs via SNMP by using custom OID scanning. This data can then be used to plan and manage maintenance, identify and remediate firmware vulnerabilities, and ensure your systems and devices are protected and up-to-date at all times.
