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. 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';…

  2. 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

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

DESITEK operates in the energy and transport sectors, focusing on niche markets for lightning and surge protection equipment and services. Its business model is B2B, targeting organizations needing electrical safety solutions. The company benefits from its parent DEHN's global presence and reputation, enhancing market positioning. The website indicates active marketing through newsletters, social media, and participation in industry events. Growth is suggested by recent office expansions and new service offerings. The partnership ecosystem includes DEHN and international affiliates. Revenue streams likely include product sales, engineering services, and testing. The company maintains a small but specialized workforce, emphasizing quality and technical expertise.

Security posture

The website enforces HTTPS and provides a cookie consent mechanism aligned with GDPR requirements, indicating a baseline of privacy and security awareness. However, the lack of visible security headers such as Content-Security-Policy and X-Frame-Options suggests potential areas for hardening. No explicit security policy or incident response information is published, which could hinder transparency and readiness in case of security incidents. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of Google Tag Manager introduces moderate user tracking, balanced by privacy controls. Overall, the security maturity is moderate with opportunities for improvement in policy communication and technical controls.

Recommendations

  1. Publish a dedicated security policy and incident response page to enhance transparency and preparedness.
  2. Implement and verify HTTP security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Investigate and resolve the absence of WHOIS registration data to improve domain trustworthiness.
  4. Regularly audit third-party scripts and analytics tools for security and privacy compliance.
  5. Enhance user trust by providing certifications or compliance badges related to security and quality.

Technical notes

Notes

The website is built on Drupal 10, a modern and widely supported CMS, ensuring a solid technical foundation. It uses JavaScript modules for navigation, search, and language switching, and integrates Google Tag Manager for analytics. The site is mobile-optimized with responsive design and accessibility features such as skip links and ARIA attributes. Performance is moderate, with deferred script loading and optimized images. SEO is supported by meta tags and Open Graph data. Hosting provider details are not evident from the content. The absence of security headers is a technical gap. Overall, the infrastructure is modern and functional but could benefit from enhanced security configurations and performance tuning.
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.
