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 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. 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
  3. 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

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 company operates as a medium-sized regional energy supplier focused on the Soltau area, serving residential and commercial customers. Their business model revolves around providing essential utility services with an emphasis on renewable energy and electromobility. The website links to partner domains related to solar energy and electromobility, indicating strategic partnerships. The presence of a news section and customer service portals suggests active engagement with customers and community. The company appears well-established with consistent branding and a comprehensive service portfolio, positioning it competitively in the regional energy market.

Security posture

The website demonstrates a good security maturity level with HTTPS enforced, cookie consent with opt-in mechanisms, CAPTCHA-protected forms, and obfuscated email addresses to reduce spam. However, the absence of explicit security headers like Content-Security-Policy and lack of published security or incident response policies indicate room for improvement. No vulnerabilities or exposed sensitive data were detected in the content. The company should consider publishing a security policy and incident response plan to enhance trust and preparedness. Overall, the security posture is solid but could be strengthened with additional transparency and technical controls.

Recommendations

  1. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response page to inform users and stakeholders about security practices and contact points.
  3. Establish and publish a vulnerability disclosure policy and security.txt file to facilitate responsible reporting of security issues.
  4. Continue to maintain GDPR compliance and transparency in data processing, including clear cookie consent and privacy policies.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities and maintain up-to-date software versions.

Notes

The website is built on Joomla CMS, leveraging modern JavaScript libraries such as jQuery, Awesomplete for autocomplete, and Swiper.js for sliders. Hosting uses Amazon AWS DNS services, indicating reliable infrastructure. The site is mobile-optimized with responsive design and good SEO practices including meta tags and structured content. Performance is moderate, with potential for optimization. Accessibility is basic but present. The use of GDPR cookie consent plugins and CAPTCHA on forms shows attention to privacy and bot protection. Overall, the technical implementation is solid with opportunities for further modernization and security enhancements.
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.
