Before diving into this article, we highly recommend reviewing our guide, “CNC Machine Security: The Dangers and Management of USB Devices“. The USB port on your CNC control remains a critical vulnerability—even in air-gapped environments.
If you’re short on time: CIMCO Software is specifically designed to support air-gapped environments and requires no active Internet connection to function effectively.
Cyber threats to manufacturing operations have grown increasingly sophisticated, with ransomware such as Black Basta posing significant risks to businesses. In response, more organizations are returning to the proven cybersecurity strategy of air-gapping or physically isolating a network from external connections, eliminating a major vector for cyberattacks. By air-gapping your CIMCO-driven operations, your organization can significantly reduce exposure to threats like Black Basta and safeguard critical CNC infrastructure.
Why Air Gap Your Most Sensitive Environment?
In 2024 alone, manufacturing was the most targeted industry for cyberattacks, representing 26% of incidents according to IBM’s X-Force report. Groups like Black Basta and Clop have demonstrated that even seemingly isolated systems can be vulnerable without proper air-gap controls. Clop’s extensive MOVEit exploits during 2023-2024 underscore the importance of strict air-gap procedures, particularly for downstream manufacturers. Implementing robust air-gap measures creates a fortress around your CNC machines, DNC systems, and sensitive data.
CIMCO Software Does Not Require Constant Connectivity
Many software solutions rely on routine connections to the internet for updates, licensing verifications, and more. However, no CIMCO products require constant connectivity except for “online subscriptions” cloud subscription offerings. All standard licensed CIMCO products can be managed offline, meaning:
- All on premise CIMCO modules can run without an active internet connection.
- Offline licensing is supported through key files and offline activation procedures.
This flexibility allows you to completely isolate your CIMCO based systems from the internet, protecting them from external threats while still running the manufacturing software you rely on.
Protecting Your CIMCO Investment
Air gapping your CIMCO environment is one important step toward a well-rounded security approach. You may also be interested in further protecting your CIMCO software investment by implementing best-practice guidelines and strategies. While air gapping protects from external threats, internal security processes, training, and technology solutions can further strengthen your defenses.
In fact, as the requirements for industry compliance (e.g., CMMC 2.0) become more rigorous, adding solutions like OT MAX for secure CNC machine connectivity can help ensure your shop floor remains both air-gapped (where appropriate) and compliant with emerging standards.
Conclusion
Cyber threats are evolving, and so must our defenses. Stuxnet demonstrated the very real risks faced by industrial control systems, especially those thought to be isolated. Air gapping—coupled with strong access controls, robust monitoring, and offline license activation—can make a powerful difference in safeguarding your most critical CIMCO environments.
By following best practices and leveraging the tools and procedures CIMCO provides, you can maintain a secure, productive, and compliant operation—even without an active internet connection.
