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. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  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

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

  • Email security: did not complete in this scan.
  • DNS health: did not complete in this scan.
  • 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

Sonion operates as a key player in the hearing instrument component manufacturing sector, leveraging decades of expertise to maintain a competitive edge. Their business model focuses on B2B partnerships, providing customized and standard solutions to hearing aid manufacturers and professional audio companies. The company’s global footprint and large employee base indicate significant operational scale. Their innovation-driven approach and quality certifications support premium positioning. The website’s content and product segmentation reflect a clear understanding of customer needs and market trends. Sonion’s social media channels and detailed product descriptions enhance brand visibility and customer engagement. The lack of WHOIS data is a minor concern but does not overshadow the company’s established market presence.

Security posture

The website employs HTTPS with a valid SSL certificate, uses Google reCAPTCHA v3 to protect forms from abuse, and implements a cookie consent mechanism compliant with GDPR. No sensitive data is exposed in the HTML source. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. There is no publicly available security or incident response policy, nor a vulnerability disclosure program or security.txt file, which limits transparency and readiness perception. The use of third-party scripts and tracking services is moderate and consent-based. Overall, the security posture is good but could be enhanced by publishing formal security policies and improving HTTP header configurations.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan on the website.
  2. Add security HTTP headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to improve protection.
  3. Publish a security.txt file to facilitate vulnerability disclosure and improve transparency.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Clarify domain registration details or ensure WHOIS data is publicly available to enhance trust.

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.
