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

Pražské vodovody a kanalizace, a.s. is a major water utility company serving Prague and surrounding regions, providing essential water supply and sewage services. The company is part of the Veolia group, a global leader in environmental services. Their website offers comprehensive information on services, customer support, water quality, and company news, targeting residential and commercial customers. The business model focuses on utility service provision with a strong emphasis on customer engagement and environmental responsibility. Technically, the website is built on the Vizus CMS platform, utilizing modern web technologies including JavaScript, CSS, and Bootstrap framework components. The site is mobile-optimized and includes a cookie consent mechanism compliant with GDPR standards. Analytics are handled via Matomo, indicating a privacy-conscious approach to user tracking. Performance is moderate with good SEO and basic accessibility features. From a security perspective, the site enforces HTTPS and provides cookie consent controls, but lacks visible security headers and explicit security policies or incident response contacts. The absence of WHOIS data reduces domain trust slightly, though the affiliation with Veolia and professional presentation support legitimacy. No critical vulnerabilities or exposed sensitive data were detected. Overall, the website presents a professional and trustworthy digital presence for a large utility company. Strategic improvements in security headers, explicit privacy and security policies, and WHOIS transparency would enhance trust and compliance further.

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

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

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

Pražské vodovody a kanalizace, a.s. holds a leading position in the Czech water utility market, serving Prague with comprehensive water and sewage services. Their competitive advantage lies in their affiliation with Veolia, enabling access to global expertise and resources. The business model is utility-based, generating revenue primarily through customer billing for water consumption and sewage services. Target customers include residential households, businesses, and public institutions in Prague. The company demonstrates growth through digital customer portals and educational outreach programs. Their partnership ecosystem includes several regional subsidiaries and related Veolia entities, enhancing service coverage and operational efficiency. Strategic observations highlight a focus on sustainability, customer engagement, and digital transformation.

Security posture

The website exhibits a moderate security maturity level with HTTPS enforced and a cookie consent mechanism in place, reflecting compliance with privacy regulations. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options indicates room for improvement in defense-in-depth. No vulnerability disclosure or incident response information is provided, which could hinder timely reporting and mitigation of security issues. Data protection practices appear adequate but could benefit from explicit documentation and transparency. Overall, the security culture is implied but not explicitly communicated, suggesting an opportunity to strengthen user trust and regulatory compliance.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish a clear privacy policy and terms of service pages accessible from the homepage to improve transparency and GDPR compliance.
  3. Establish and publicize a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance WHOIS data transparency or ensure domain registration details are publicly available to improve domain legitimacy and trust.
  5. Regularly audit and update cookie consent mechanisms and analytics configurations to maintain privacy compliance and user trust.

Technical notes

Notes

The website is built on a modern CMS platform (Vizus CMS) with standard web technologies including JavaScript and CSS. It uses Bootstrap for responsive design and Matomo for analytics, indicating a focus on privacy-friendly tracking. The site is mobile-optimized with good SEO practices and clear navigation. Performance is moderate, with potential for improvement through optimization of assets and caching. The absence of advanced accessibility features suggests an area for enhancement to meet broader user needs. No hosting provider details were identified, limiting infrastructure assessment. Overall, the technical implementation supports a professional user experience but could benefit from security and accessibility upgrades.
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.
