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

9 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

    • High

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 in the energy sector as a public utility provider, focusing on water and sewage services. It maintains multiple subsidiary branches serving different localities, indicating a broad regional footprint. The business model is service-oriented, targeting residential and commercial customers requiring water supply and wastewater management. Their market position is stable with over two decades of operation, supported by EU-funded infrastructure projects. The company leverages partnerships and maintains transparency through dedicated project and transparency portals. Growth indicators include ongoing projects and community engagement initiatives. The company’s digital ecosystem includes social media channels and a modern website, supporting customer interaction and information dissemination.

Security posture

The website enforces HTTPS and uses Cloudflare for DNS and CDN services, providing a strong baseline for security. Cookie consent mechanisms and privacy policies are well implemented, supporting GDPR compliance. However, the absence of explicit security headers like Content-Security-Policy and lack of a published security policy or incident response contacts limit the security maturity. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party scripts such as Google Analytics and UserWay accessibility widget is standard but should be regularly audited. Overall, the security posture is good but can be enhanced by adopting additional security best practices and transparency measures.

Recommendations

  1. Implement and publish explicit security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Develop and publish a formal security policy and incident response contact information to improve transparency and readiness.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure and improve trust with security researchers.
  4. Regularly audit third-party scripts and libraries to ensure they are up to date and free from known vulnerabilities.
  5. Enhance user trust by providing more visible trust signals such as customer testimonials, awards, or certifications on the website.

Technical notes

Notes

The website is built on Joomla CMS, utilizing Foundation framework for responsive design, jQuery, Font Awesome, Google Fonts, and Material Icons for UI elements. Hosting is supported by Cloudflare, providing DNS and CDN services that improve performance and security. The site loads moderately fast with good mobile optimization and accessibility features, including the UserWay widget. SEO is supported by proper meta tags and structured navigation. The technical stack is modern and well-maintained, though some security headers are missing. The site uses Google Analytics for visitor tracking, balanced with GDPR-compliant cookie consent. Overall, the technical infrastructure is solid with room for incremental security and performance improvements.
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.
