Cyber Resilience Act:
What embedded systems manufacturers must do now

Every machine with firmware is a regulated product from 11 September 2026 — with a 24-hour vulnerability notification duty.

Product with digital elements (CRA Art. 3)

Any software or hardware product that can be connected directly or indirectly to a network or device — including firmware, embedded operating systems, and remote access solutions.

All of the following are CRA-relevant if you manufacture them:

MCU (microcontroller unit)
PLC
IPC (industrial PC)
Edge device / IoT gateway
Variable-frequency drive with update capability
OPC UA control unit
Safety controller
Industrial gateway with remote access

CRA Annex II: which category is your product?

CategoryConformity pathTypical products
Standard productsSelf-assessment (Annex IX) — no third partySimple sensors, standard IoT devices
Important products Class I (Annex II)Self-assessment OR voluntary third-party cert; without harmonised standard: third party mandatoryIndustrial firewalls, standard PLCs, industrial routers
⚠ Important products Class II (Annex II)Mandatory third-party assessmentSafety controllers, industrial gateways with remote access, PLCs in critical infrastructure

Security by design (5 requirements)

  • No known vulnerabilities at market placement
  • Secure by default No default passwords, no open ports without need
  • Minimal attack surface Only necessary interfaces enabled
  • Authentication against unauthorised access
  • Encryption of sensitive data — in transit and at rest

SBOM — new obligation under CRA Art. 13

CRA Art. 13 requires manufacturers to create an SBOM — a machine-readable inventory of all software components.

  • Format: CycloneDX or SPDX (not PDF)
  • Content: all components incl. open-source libraries, version numbers, CVE references
  • Legacy systems: SBOM creation is often the hardest CRA step — reverse engineering dependencies may be required

24-hour notification table

Fielded legacy products: notification duty from 11 Sep 2026 also applies to vulnerabilities in already shipped devices. Without a vulnerability disclosure policy, you are non-compliant from the first known incident.

IEC 62443: the OT security standard for your control systems

OWASP Embedded Top 10 applies at MCU/SoC level. For industrial control systems (PLC, IPC, safety controller), customers and market surveillance check against IEC 62443-4-2:2019 (Security Level SL-C 1–4). Solvetronix supports both standards.
