By December 2027, any internet-connected product sold into the European Union must meet strict cybersecurity requirements. The EU Cyber Resilience Act (CRA) is a sweeping regulation designed to ensure products are secure by design and secure by default.
For manufacturers of EtherNet/IP-enabled devices, the CRA isn’t a future concern. It’s a design, sourcing, and roadmap issue that merits attention now. Industrial networks are increasingly connected, converged, and visible to regulators, which puts industrial communication technologies squarely in scope.
What Is the Cyber Resilience Act?
The Cyber Resilience Act is a European Union cybersecurity regulation that establishes mandatory security requirements for products with digital elements. Its goal is to raise the baseline level of cybersecurity across the EU by holding manufacturers accountable throughout a product’s lifecycle: from development and deployment to vulnerability handling and updates.
Importantly, the CRA applies regardless of where a product is manufactured. If it’s sold into the EU and connects to a network, it’s likely covered.
Who the CRA Impacts in the Industrial Automation Ecosystem
The CRA affects more than traditional IT vendors. In the context of industrial automation and EtherNet/IP, impacted organizations include:
- Manufacturers of EtherNet/IP-enabled devices and components
- OEMs and machine builders shipping systems into the EU
- Suppliers embedded within larger systems sold to EU customers
- Non-EU companies exporting connected industrial products to Europe
As IT and OT environments continue to converge, regulators increasingly expect the same rigor applied to enterprise technology to be reflected in industrial products.
CRA Timeline: Why 2027 Is Closer Than It Looks
Although the CRA fully takes effect in December 2027, key obligations begin earlier:
- Now (2025–2026):
Product architecture, protocol selection, and supplier decisions must account for security-by-design expectations. - September 2027:
Manufacturers must begin reporting actively exploited vulnerabilities and noncompliance. - December 2027:
Full enforcement begins, with potential market access restrictions for noncompliant products.
For many manufacturers, this timeline overlaps directly with current product development cycles, making early preparation essential.
What the CRA Means for EtherNet/IP and Industrial Networks
The CRA brings new expectations for EtherNet/IP and industrial connectivity, including:
- Secure authentication between devices
- Protection of data integrity and confidentiality
- Controlled access to industrial networks
- Cybersecurity maintained across the full product lifecycle
In short, industrial communication protocols are no longer exempt from regulatory scrutiny.
The Role of CIP Security in Supporting CRA Readiness
Technologies such as CIP Security can support implementation of secure communications and authentication mechanisms that align with common regulatory expectations.
Manufacturers leveraging CIP Security can better support:
- Defense-in-depth strategies
- Secure device-to-device communication
- Alignment with recognized industrial cybersecurity standards
However, CIP Security can be viewed as a foundational enabler, not a standalone compliance solution. CRA readiness also requires vulnerability management processes, secure development practices, and long-term support commitments.

The Time to Prepare Is Now
The Cyber Resilience Act represents a fundamental shift in how industrial products are evaluated and regulated in the EU.
The organizations that integrate cybersecurity into product architecture now will be positioned to maintain EU market access, reduce remediation costs, and build long-term customer trust.
