Cyber Resilience Act: What Counts Now

At the heart of the CRA are all "products with digital elements" - a deliberately broad term. This includes:

• Software products of any kind
• Networked devices (IoT)
• embedded systems in industrial environments

The decisive differentiation is made via the risk potential:

• Non-critical products are subject to standard requirements
• Critical products (e.g., safety-relevant components) must meet significantly stricter testing and verification requirements

A key element here is the CE marking: in the future, it will also certify a product's cybersecurity and will be a prerequisite for sales in the EU market. For many companies, this means that security will become part of the formal product approval process.

One of the most important principles of the CRA is also one of the most demanding: security must be anchored in the product from the outset. This includes in particular:

• Minimizing the attack surface
  Only necessary functions and interfaces - no unnecessary open flanks
• Secure by default
  Products must not be delivered with insecure default configurations
• Lifecycle view
  Security does not end with the release, but encompasses the entire lifecycle - including updates and support

In practice, there is often a gap: Development processes are functionally optimized, but not consistently aligned with security. It is precisely at this point that it is decided whether CRA requirements are integrated efficiently or have to be "retrofitted" later at great expense.

The CRA mandates vulnerability management as an ongoing task. Core requirements are:

• Active treatment of vulnerabilities
  Companies must systematically identify, assess, and fix known and actively exploited vulnerabilities
• 24-hour reporting obligation to ENISA
  If a vulnerability is actively exploited, this must be reported within 24 hours
• Coordinated Vulnerability Disclosure
  Clear processes for dealing with externally reported vulnerabilities
• Software Bill of Materials (SBOM)
  Transparency about deployed software components and dependencies

This area in particular shows the extent to which CRA requires operational capabilities. It is not enough to define guidelines - companies must be able to manage vulnerabilities in real time. In practice, it is clear that without structured processes and clear responsibilities, implementation quickly becomes an organizational challenge.

In addition to technical measures, the CRA attaches great importance to traceability. Companies must provide comprehensive documentation:

• Technical documentation
  Safety concepts, architecture, risk assessments
• EU declaration of conformity
  Official confirmation that the product meets all requirements
• Internal control procedures
  Processes for continuously ensuring compliance

These requirements affect not only engineering teams but also governance, quality management, and compliance functions. Experience has shown that one of the biggest challenges here is combining technical implementation and regulatory verification.

The CRA is not a "soft law". Violations have tangible consequences:

• Substantial fines
  Depending on the severity and scope of the infringement
• Distribution bans
  Products can be withdrawn from the market or not approved in the first place
• Reputational risks
  Security flaws are becoming increasingly public and business-critical

This makes it clear: compliance is not optional, but business-critical.

The Cyber Resilience Act translates cybersecurity into concrete, verifiable requirements along the entire product life cycle. For many companies, this means a profound change: from selective security measures to structured, end-to-end processes.

Organizations that operationalize these requirements early on and integrate them into their product development not only achieve compliance but also build sustainable stability and market trust.
