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

4 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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';…

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

The platform occupies a strong market position as a trusted Swiss vertical industry portal for handwerk and construction sectors. Its business model revolves around providing verified ratings, certifications, and comparison tools to various stakeholders including customers, professionals, and investors. Revenue streams likely include premium certifications, advertising, job portal services, and partnerships with industry players. The extensive partner ecosystem includes marketing networks, job channels, and related service providers, enhancing its market reach and credibility. The platform's focus on transparency, real-time data, and integration of ESG and KI-optimized content positions it well for future growth and digital maturity within the Swiss construction industry.

Security posture

handwerker.ch exhibits a mature security posture with HTTPS enforced, CSRF protection, and Google reCAPTCHA integration to mitigate automated abuse. However, the absence of published security policies, incident response contacts, and security.txt files indicates gaps in formal security governance and vulnerability disclosure readiness. Security headers are not explicitly confirmed, suggesting potential improvements in HTTP header configurations. No vulnerabilities or exposed sensitive data were detected in the analysis. Overall, the platform maintains good security hygiene but should enhance transparency and formalize incident response mechanisms to align with best practices and compliance requirements.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and compliance.
  2. Add incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and verify HTTP security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  4. Consider publishing a security.txt file to facilitate responsible vulnerability disclosure.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used.

Technical notes

Notes

The website uses a modern technology stack with Google Analytics and Google Tag Manager for analytics, Google reCAPTCHA v3 for bot protection, and slick carousel for interactive UI elements. The site is mobile optimized with responsive design and includes SEO best practices such as meta tags and Open Graph data. Performance is moderate with room for optimization. No CMS is explicitly detected, suggesting a custom or proprietary platform. Accessibility is basic but could be improved. Hosting provider details are not disclosed. Overall, the technical infrastructure supports a professional and scalable online platform with opportunities to enhance performance and accessibility.
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.
