groov Products: Cybersecurity


groov EPICWhen you’re gathering, processing, and sharing operational data from industrial equipment on premises or located remotely, cybersecurity is a big worry. Your systems and equipment—and the data in them—are essential and sensitive, and you need industrial internet of things (IIoT) devices and software that protect them.

For all digital systems, security is a complex issue with different implications depending on your organization and your system. Security requirements constantly change as your system evolves, and building security into your system design is key.

groov RIOSecurity experts recognize several elements of system security, including physical security, policies and procedures, and network security.

groov products help you address network security requirements.

Of course the ultimate security of your system depends on you, but groov products are here to help. Using groov product security features can help you comply with security guidelines as outlined in the ISA/IEC 62443 specification.


“Security is a process, not a product.”

- Bruce Schneier


To address security’s complex, changing nature, you need to understand security risks, understand your environment, and understand the security tools you have to work with.

Opto 22’s groov products were designed from the ground up to help you build a secure extended system.
