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

2 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.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

Sonova's market position as a global leader in hearing care is supported by diversified business units and a broad portfolio of brands. The company targets consumers with hearing needs, audiological professionals, and investors. Its business model combines manufacturing, licensing, and audiological services distributed globally. The website's investor relations section and financial reports indicate transparency and corporate governance maturity. Partnerships and subsidiaries are clearly identified, enhancing brand strength and market reach. The digital ecosystem includes social media engagement and detailed content on sustainability and innovation, signaling growth orientation and corporate responsibility.

Security posture

The website demonstrates a good security maturity level with HTTPS enabled and a cookie consent mechanism compliant with GDPR. The presence of a coordinated vulnerability disclosure policy indicates proactive security management. However, the absence of explicit security headers and a security.txt file suggests room for improvement. No exposed sensitive data or vulnerable libraries were detected. Incident response contact information is not explicitly provided, which could be enhanced to improve readiness and trust. Overall, the security posture is strong but could benefit from additional best practices to further reduce risk.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a security.txt file to facilitate vulnerability reporting and improve transparency.
  3. Provide explicit incident response contact emails (e.g., security@sonova.com) on the website.
  4. Regularly review and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Enhance data retention policy disclosures and privacy transparency for users.

Technical notes

Notes

The website is built on Drupal 10, leveraging modern JavaScript libraries including jQuery and YouTube Player API. Google Tag Manager is used for analytics and tracking, integrated with OneTrust for cookie consent management. The site is mobile optimized with responsive design and accessibility features such as skip links and ARIA roles. Performance is moderate, with room for optimization in loading times. The technical infrastructure supports a professional and scalable digital presence, though hosting provider details are not explicitly identified. Overall, the technical implementation supports business goals effectively with opportunities for further modernization and security enhancements.
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.
