RED Cybersecurity Essentials: What Wireless Product Teams Should Prepare

Radio Equipment Directive compliance used to mean RF + EMC + safety. For many connected products, cyber-related essential requirements now sit in the same market-access path.

What to assemble early

• Asset and data-flow diagram (what the device stores/transmits)
• Threat / risk assessment proportionate to use case
• Secure update strategy (who signs firmware, how keys are protected)
• Access control defaults (no universal passwords in production)
• Vulnerability handling contact and supported lifetime statement
• Evidence mapping to harmonized standards (e.g. EN 18031 family where applicable)

Engineering habits that help

1. Separate debug interfaces from production (disable or authenticate).
2. Inventory third-party stacks and their CVEs as part of release gates.
3. Make “factory reset restores secure defaults” a test case.
4. Align privacy notices with what the radio product actually collects.

Pitfalls

• Assuming module vendor cyber docs cover your cloud + app + device system.
• Shipping with open UART/JTAG on retail units.
• No plan for security updates after launch.

FAQ

Is this the same as IEC 62443?

Related ideas, different scopes. 62443 is often industrial/OT. RED cyber obligations are tied to radio product placement in the EU. Map intentionally.
