68/100

0–100, higher is better. How it is calculated

TELSONIC AG is a Swiss-based manufacturer specializing in industrial ultrasonic systems with a global presence through multiple subsidiaries. The company offers a broad range of ultrasonic technologies including metal and plastic welding, sieving, cleaning, and cutting, targeting industries such as automotive, electronics, medical, and packaging. Their market position is that of an established medium-sized enterprise with recognized certifications and a strong brand identity. Technically, the website is built on TYPO3 CMS with modern JavaScript libraries and includes GDPR-compliant privacy and cookie policies, reflecting a mature digital infrastructure. Security posture is generally strong with HTTPS and consent mechanisms, though lacking explicit security headers and incident response information. WHOIS data is missing, which slightly reduces trustworthiness but is offset by the professional content and global footprint. Overall, the website is well-designed, user-friendly, and trustworthy, with room for improvement in security transparency and WHOIS data availability.

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.

    • 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

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

  • Security headers: 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

TELSONIC AG operates in the manufacturing and technology sectors, focusing on ultrasonic industrial applications. Their business model revolves around product innovation and global sales through subsidiaries in Europe, North America, and Asia. The company targets industrial manufacturers requiring precision ultrasonic solutions, leveraging certifications and sustainability trends as competitive advantages. Growth indicators include recent news about global expansion and product enhancements. The partnership ecosystem is implied through multiple subsidiaries and a partner login portal. Strategic observations suggest a focus on sustainability, electromobility, and additive manufacturing as future growth areas.

Security posture

The website demonstrates a moderate to strong security maturity level with enforced HTTPS and cookie consent mechanisms aligned with GDPR. However, the absence of explicit security headers such as Content-Security-Policy and lack of published security policies or incident response contacts indicate gaps in security transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The missing WHOIS data is a concern for domain legitimacy verification but does not directly impact website security. Overall, the security posture is adequate for business operations but could be enhanced by publishing security policies and improving header configurations.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response information on the website.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Investigate and resolve the missing WHOIS registration data to improve domain legitimacy and trust.
  4. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Maintain and regularly update cookie consent and privacy compliance mechanisms to align with evolving regulations.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust open-source content management system, supplemented by jQuery and modern JavaScript libraries for interactivity. Google Tag Manager is used for analytics and tracking, integrated with a CookieFirst consent management platform ensuring GDPR compliance. The site loads with moderate performance and is optimized for mobile devices with good navigation clarity. No major technical debt or deprecated technologies were detected. Opportunities exist to improve accessibility features and implement advanced security headers to reduce risk exposure.
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.
