Risk levelLow

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

ELCON is a large Danish energy sector company specializing in electrical installations, energy optimization, and green technology solutions primarily serving eastern Denmark. The company offers a broad range of services including traditional electrical work, automation, intelligent building solutions, and 24-hour emergency electrician services. Their market position is strong with over 1,100 employees and a focus on sustainable energy solutions. Technically, the website is well-structured, mobile-optimized, and uses modern technologies such as Google Tag Manager for analytics and marketing. Security posture is good with HTTPS enforced and no visible vulnerabilities, though security headers could be improved and incident response contacts are not explicitly provided. Privacy compliance is adequate with a comprehensive privacy policy but lacks a visible cookie consent mechanism. Overall, the website reflects a professional and trustworthy business with minor areas for improvement in privacy and security transparency.

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

5 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

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics

      What to do: Document all third-party data sharing in your privacy policy

  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

  • 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

ELCON operates as a service provider in the energy sector, targeting businesses and customers in eastern Denmark. Their competitive advantage lies in their comprehensive service portfolio combining traditional electrical services with advanced green and intelligent building technologies. The business model focuses on long-term service agreements and energy consulting, supported by a large workforce and regional presence. Partnerships with companies like CLEVER for electric vehicle charging solutions indicate a strategic ecosystem approach. The company demonstrates growth potential through green technology adoption and digital service integration. Their website content and structure support clear communication of services and contact points, enhancing customer engagement and trust.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and no exposed sensitive data. Use of Google Tag Manager is noted, but no vulnerable libraries or insecure forms were detected. However, the absence of explicit security headers such as Content-Security-Policy and lack of published incident response contacts or vulnerability disclosure mechanisms represent gaps. GDPR compliance is supported by a comprehensive privacy policy, but cookie consent mechanisms are missing, which could pose compliance risks. Overall, the security maturity is good but could be enhanced by adding security headers, incident response information, and cookie consent transparency.

Recommendations

  1. Implement a visible cookie consent banner to ensure GDPR compliance and user transparency.
  2. Publish explicit incident response contact information (e.g., security@ or abuse@ email) to improve security readiness.
  3. Add a security.txt file to facilitate vulnerability disclosure and improve trust.
  4. Enhance HTTP security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve data protection.

Technical notes

Notes

The website uses modern HTML5 and CSS3 standards with JavaScript for interactivity and Google Tag Manager for analytics and marketing. The site is mobile-optimized and accessible with good SEO practices including meta tags and structured data (JSON-LD BreadcrumbList). Performance is moderate with deferred script loading. No CMS or hosting provider was explicitly detected. The technical implementation supports a professional user experience but could benefit from enhanced security headers and explicit privacy controls. No technical debt or legacy technology indicators were found.
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.
