The European Cyber Resilience Act (CRA) is fundamentally changing how manufacturers of connected products deal with cybersecurity after products are released to the market.
One requirement in particular is already creating uncertainty across the industry:
Manufacturers must report actively exploited vulnerabilities and severe incidents to ENISA within 24 hours.
At first glance, this sounds straightforward. In reality, it introduces a completely different operational challenge for manufacturers, PSIRTs, security teams, and product organizations.
Because the real difficulty is not the reporting itself.
The real challenge is determining, fast enough, whether a vulnerability is actually relevant, exploitable, and reportable.
A Common Misunderstanding About CRA Reporting
A lot of organizations currently believe the CRA requires every vulnerability to be reported within 24 hours.
That is not correct.
The obligation specifically focuses on:
- Vulnerabilities that are being actively exploited
- Severe incidents impacting the security of the product
This distinction is extremely important.
Modern products contain thousands of software components, dependencies, operating system packages, libraries, containers, firmware elements, and third-party integrations. Vulnerabilities are discovered continuously.
Not every vulnerability creates a real-world risk.
Not every vulnerability affects deployed devices.
Not every vulnerability is exploitable in a specific product context.
The challenge is separating noise from actual exposure.
And that needs to happen fast.
Why Most Organizations Are Not Ready
In many organizations today, vulnerability management for connected products is still fragmented.
Security teams often rely on a combination of:
- SBOM exports
- Spreadsheets
- Separate scanning tools
- Ticketing systems
- Manual product inventories
- Email communication between teams
- Static compliance documentation
When a new vulnerability appears, organizations frequently struggle to answer critical questions quickly:
- Which products are affected?
- Which versions are exposed?
- Which software component introduced the issue?
- Is the vulnerable component actually present in production devices?
- Is there evidence of active exploitation?
- Which customers or deployments are impacted?
- Is mitigation already available?
- Does this situation trigger CRA reporting obligations?
Without centralized visibility, even identifying the scope of exposure can take days.
Under CRA timelines, that is simply too slow.
The Operational Reality Of A 24-Hour Reporting Window
The 24-hour reporting obligation effectively means organizations need operational cybersecurity visibility at all times.
Not once per year during an audit.
Not only during penetration testing.
Not only when customers report incidents.
Continuously.
Manufacturers need to maintain an up-to-date understanding of:
- Device composition
- Software components
- Hardware dependencies
- Vulnerability exposure
- Product lifecycle status
- Mitigation tracking
- Exploit intelligence
- Customer impact
This is where many traditional IT-centric vulnerability management approaches fall short for embedded systems, IoT devices, industrial products, medical devices, automotive systems, and long lifecycle connected products.
These environments are more complex, more fragmented, and often operate for many years after deployment.
How ARIANNA Helps Organizations Prepare For CRA
ARIANNA was designed specifically to solve this challenge for connected products and embedded environments.
ARIANNA provides continuous vulnerability monitoring and device visibility by combining:
- Device Models
- SBOM management
- HBOM management
- Continuous vulnerability intelligence
- Product-level exposure tracking
- Vulnerability lifecycle management
- Reporting and evidence generation
Instead of manually reconstructing product exposure during a security incident, organizations can immediately determine:
- Which devices are affected
- Which components are involved
- Which versions are vulnerable
- Whether exploitation is relevant
- What mitigation actions are available
- Which products may trigger CRA reporting obligations
This dramatically reduces the time needed to move from vulnerability disclosure to informed decision-making.
CRA Compliance Is Becoming An Operational Discipline
The Cyber Resilience Act is not just introducing new documentation requirements.
It is pushing manufacturers toward continuous operational cybersecurity management throughout the entire product lifecycle.
The organizations that will handle CRA successfully are not necessarily the ones with the largest number of security tools.
They will be the organizations that have:
- Visibility
- Traceability
- Product intelligence
- Structured vulnerability processes
- Fast decision-making capabilities
Because when the reporting clock starts ticking, there is no time to manually rebuild your software supply chain.
You need answers immediately.
