Risk levelMedium

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

TSÚ is a Slovakian company focused on creating a world of safe products, likely operating in the manufacturing and product safety certification sector. The website presents a professional image with a clear business focus on product safety and certification services. The technical infrastructure uses modern frontend technologies such as Vue.js and Google Fonts, with good performance and mobile optimization. Security posture is solid with HTTPS and security headers properly configured, although privacy compliance is lacking due to missing privacy and cookie policies. Contact information is limited to contact forms without direct emails or phone numbers, which may affect user trust and accessibility. Overall, the website is safe, professional, and moderately mature digitally, but could improve privacy transparency and direct contact options.

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

9 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. Security headers

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

TSÚ operates in the manufacturing and product safety sector in Slovakia, targeting businesses requiring product safety certification and consulting. The business model appears service-oriented, focusing on compliance and safety assurance. The website content and design suggest a medium-sized enterprise with consistent branding and a professional market position. There is no evidence of parent or subsidiary companies. The company leverages modern web technologies but lacks advanced marketing or analytics tools, indicating a focus on core business rather than aggressive digital marketing. The absence of explicit privacy and terms policies may reflect a need for enhanced compliance maturity.

Security posture

The website enforces HTTPS and includes key security headers such as Strict-Transport-Security, X-Content-Type-Options, X-Frame-Options, and Content-Security-Policy, indicating a good baseline security posture. No exposed sensitive data or vulnerable libraries were detected. However, the lack of a vulnerability disclosure policy or security.txt file and absence of incident response contact channels suggest limited transparency in security incident handling. The site uses deferred script loading to improve performance and reduce attack surface. Overall, the security posture is good but could be enhanced by adding explicit security policies and incident response information.

Recommendations

  1. Publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Add direct contact information such as company emails and phone numbers for better accessibility.
  3. Implement a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve usability for all users.
  5. Consider adding trust seals, certifications, or testimonials to strengthen business credibility.

Technical notes

Notes

The website uses a modern frontend stack centered on Vue.js and Google Fonts, with CSS3 styling and deferred JavaScript loading for performance optimization. The site is mobile optimized and has a clear navigation structure. No CMS was detected, suggesting a custom or proprietary platform. Hosting provider details are not evident from the data. Performance is moderate, with good SEO meta tags and Open Graph data for social sharing. Accessibility is basic but could be improved. No analytics or tracking scripts were found, indicating minimal user tracking. The technical implementation is solid with room for enhancements in accessibility and privacy compliance.
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.
