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

ČEVAK a.s. is a Czech water utility company specializing in the operation and management of water supply and wastewater infrastructure. The company serves residential customers, municipalities, and water infrastructure owners, providing key services such as water and sewer connections, water quality testing, customer service, and technical statements. The website reflects a well-established regional utility with a professional online presence and ISO 27001 certification indicating a commitment to information security management. Technically, the website employs modern technologies including Google Tag Manager and Google Maps API, with good mobile optimization and accessibility features. The site uses HTTPS exclusively, ensuring secure communications, and implements a comprehensive cookie consent mechanism aligned with GDPR requirements. However, some security headers are not visibly implemented, and WHOIS data for the domain is unavailable, which slightly impacts trustworthiness. From a security perspective, the site demonstrates good practices such as secure login portals and no exposed sensitive data. The absence of explicit incident response contacts and vulnerability disclosure mechanisms suggests areas for improvement. Overall, the security posture is solid but could be enhanced by adding security headers and publishing a security.txt file. The overall risk assessment is moderate with a good balance of content quality, technical implementation, and security. Strategic recommendations include improving transparency on security policies, enhancing WHOIS data visibility, and strengthening security headers to further bolster trust and compliance.

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.

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

ČEVAK a.s. holds a significant position in the Czech water utility sector, focusing on essential public services. Its business model revolves around providing water supply and wastewater management services to a large customer base, including municipalities and private owners. The company leverages digital tools for customer engagement and operational transparency, such as online portals and detailed service information. The presence of ISO 27001 certification indicates a mature approach to information security, which is critical in utility services. The company maintains active social media channels and partners with related service providers, enhancing its market reach and customer support capabilities. Growth indicators include ongoing infrastructure projects and public communication about service improvements. The company’s operations appear stable with a focus on compliance and customer satisfaction.

Security posture

The website’s security posture is generally strong, with HTTPS enforced site-wide and no visible leakage of sensitive information. The use of cookie consent banners and privacy policies demonstrates compliance with GDPR. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security hardening. No vulnerability disclosure or incident response contacts are publicly available, which could hinder timely reporting and mitigation of security issues. The WHOIS data absence raises minor concerns about domain transparency but does not directly impact site security. Overall, the site is secure for typical user interactions but would benefit from enhanced security header implementation and formal vulnerability disclosure channels.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to improve protection against common web attacks.
  2. Publish a security.txt file and provide clear incident response contact information to facilitate vulnerability reporting and response.
  3. Investigate and resolve the absence of WHOIS data to improve domain transparency and trustworthiness.
  4. Regularly audit third-party scripts and tracking tools to ensure no vulnerabilities or privacy issues are introduced.
  5. Enhance documentation and transparency around data retention policies and privacy compliance to build user trust.

Technical notes

Notes

The website uses a modern technology stack with Google Tag Manager for analytics and Google Maps API for interactive mapping features. The presence of Typeahead.js enhances user experience in search forms. The site appears to be custom-built or uses a proprietary CMS, as no common CMS signatures were detected. Performance is moderate with good mobile responsiveness and accessibility features. SEO is supported by proper meta tags and structured navigation. However, the lack of visible security headers and incomplete WHOIS data indicate areas where technical improvements can be made to strengthen security and trust. Hosting provider details are not discernible from the content provided.
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.
