Connecting machines and equipment to the internet became easier than ever when we launched the Arduino Opta micro PLC, enabling real-time control, monitoring, predictive maintenance and more – in industries ranging from smart agriculture to large-scale manufacturing to building automation. 

Supporting our well-known Arduino sketch programming experience and any of the five IEC 61131-3 PLC standard languages, the Opta was designed to be powerful yet easy to use from the start – as well as highly secure. Indeed, the Opta supports OTA firmware updates and ensures data security from the hardware to the Cloud thanks to the physical onboard secure element and X.509 Standard compliance. 

In addition, as part of the go-to-market for this innovative hardware solution, we actively committed to verifying its security against the threats posed by cyberattacks. 

To this end, in late 2023 we started a collaboration with global cybersecurity provider HWG Sababa: their Offensive Team engaged in a penetration test that lasted weeks, assessing Opta’s security posture and pinpointing any weaknesses. Their meticulous report allowed us to remedy any vulnerabilities before they became actual issues, and now we are proud to say the Opta is more secure than ever.

The software patches and configuration updates we carried out are part of our ongoing commitment to providing you the most robust solutions on the market in every respect – including against ever-evolving cyber threats. The rigorous testing process and following activities our team completed only confirms Opta as an ideal candidate for any industrial automation project you have in mind.
