This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

3 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Silicon Labs operates as an essential technology provider in the IoT and wireless connectivity sector. Their competitive advantage lies in a broad wireless portfolio, integrated hardware and software platforms, and strong ecosystem partnerships. The business model focuses on product sales, developer tools, and services including custom manufacturing and SDK support. The company targets developers and enterprises in smart home, industrial, commercial, and healthcare markets. Growth indicators include active developer engagement, frequent events, and comprehensive content offerings. The partnership ecosystem is robust, including integrations with Amazon Sidewalk, Google Home, and others. The company maintains a professional and consistent brand presence with strong trust signals such as privacy policies and security disclosures.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, cookie consent, and a public vulnerability reporting mechanism. No exposed sensitive data or vulnerable libraries were detected. Compliance with GDPR is indicated by privacy and cookie policies. Incident response readiness is supported by a dedicated security page. However, explicit security headers like Content-Security-Policy and X-Frame-Options were not confirmed in the provided data and should be verified. Accessibility compliance is basic and could be improved to meet broader standards. Overall, the security culture appears proactive but could benefit from enhanced transparency and technical controls.

Recommendations

  1. Verify and implement explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Enhance website accessibility features to meet WCAG standards for broader compliance and usability.
  3. Conduct regular audits of third-party scripts and marketing tools to mitigate potential vulnerabilities.
  4. Improve transparency of WHOIS data or provide registrar information to strengthen domain trustworthiness.
  5. Maintain and update privacy and security policies to reflect evolving regulatory requirements and best practices.

Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
