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

6 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • 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. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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 essential energy sector, focusing on water supply and wastewater management. It targets residential and commercial customers in specific Czech regions, leveraging its market leadership and ISO certifications as competitive advantages. The business model centers on utility services with revenue streams from water supply, wastewater treatment, and related customer services. Partnerships with Aqualia and PragueBest indicate a strong ecosystem supporting operational and digital capabilities. Growth indicators include ongoing infrastructure modernization and active communication channels. The website supports customer engagement through account management and appointment booking features.

Security posture

The website enforces HTTPS and implements cookie consent, reflecting awareness of privacy and security requirements. However, the lack of visible security headers such as Content-Security-Policy and X-Frame-Options limits protection against common web attacks. No incident response or vulnerability disclosure information is published, which could hinder timely security issue reporting. The absence of contact emails reduces direct communication channels for security concerns. Overall, the security maturity is moderate with room for enhancements in headers, transparency, and incident readiness.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish clear incident response and vulnerability disclosure information, including a security.txt file.
  3. Add verified company contact email addresses for customer and security communications.
  4. Conduct regular audits of third-party scripts to mitigate supply chain risks.
  5. Improve accessibility features to meet WCAG standards and enhance user inclusivity.

Technical notes

Notes

The website uses a modern JavaScript stack with libraries such as Tiny Slider and GLightbox for UI components, and Google Tag Manager for analytics. The presence of a cookie consent script indicates compliance with privacy regulations. The site is mobile optimized with responsive images and navigation. Performance is moderate, with potential improvements in loading speed and accessibility. No CMS or hosting provider information is evident from the HTML. The absence of WHOIS data and security headers suggests some technical gaps in domain management and security hardening.
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.
