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

DEHN Sverige AB is a well-established company specializing in lightning protection, surge protection, and industrial safety equipment with over 112 years of expertise. The company targets professional and industrial clients in the energy and transportation sectors, offering comprehensive protection solutions and consulting services. The website reflects a mature business with consistent branding and detailed product information, supporting its market position as a trusted provider in its industry. Technically, the website is built on Drupal 10, leveraging modern JavaScript and Google Tag Manager for analytics and tracking. The site is mobile-optimized, accessible, and SEO-friendly, providing a good user experience. However, the hosting provider and domain registration details are not publicly available, which slightly impacts trust. Security-wise, the site enforces HTTPS and has a cookie consent mechanism, but lacks explicit security policies, incident response contacts, and security headers. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is well addressed with a comprehensive privacy policy and cookie management. Overall, the website presents a professional and trustworthy digital presence for DEHN Sverige AB, though improvements in transparency around domain registration and security policies would enhance trust and compliance.

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

8 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

    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 Strict-Transport-Security header

      Forces HTTPS connections

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

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

Business profile

DEHN Sverige AB operates primarily in the energy and transportation sectors, focusing on B2B sales of electrical safety products. The company benefits from a long history and established brand reputation. Its business model includes product manufacturing, distribution, and consulting on protection concepts. The website indicates a medium-sized enterprise with a strong regional presence in Sweden and international connections through the DEHN international domain. The company leverages digital channels for marketing and customer engagement but could improve by adding more direct contact details and clearer terms of service. Partnerships are suggested through the international DEHN domain, and social media presence on LinkedIn and YouTube supports brand visibility. The absence of detailed financial or registration data limits deeper business intelligence insights.

Security posture

The website demonstrates a solid baseline security posture with HTTPS enabled and cookie consent implemented. However, the absence of security headers such as Content-Security-Policy and lack of published security or incident response policies represent gaps. No security.txt or vulnerability disclosure mechanisms were found, which could hinder responsible vulnerability reporting. The site does not expose sensitive data or use vulnerable libraries based on the analysis. Overall, the security maturity is moderate to good but could be improved by adopting best practices in security headers and transparency. Compliance with GDPR is evident through privacy and cookie policies, but incident response readiness and security culture indicators are not visible on the site.

Recommendations

  1. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Verify and publish domain registration details or clarify domain ownership to improve trustworthiness.
  5. Include terms of service and more explicit contact details such as company phone numbers and emails to enhance business credibility.

Technical notes

Notes

The website is built on Drupal 10 CMS, indicating a modern and maintainable platform. It uses JavaScript extensively for UI components and Google Tag Manager for analytics. The site is mobile-optimized and accessible, with good SEO practices including meta tags and Open Graph data. Performance is moderate, with multiple asynchronously loaded scripts and preloaded resources. No major technical debt or deprecated technologies were detected. Hosting provider details are not disclosed, which could be a risk factor for infrastructure transparency. Overall, the technical infrastructure supports a professional and functional website experience.
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.
