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

3 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.

    • 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

  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
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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 holds a strong market position as a key water utility provider in the Brno region, serving a large customer base with comprehensive water and wastewater services. Their business model focuses on regulated utility services with customer account management and public information portals. The website content and structure support customer engagement and transparency, including detailed service descriptions, emergency information, and downloadable resources. Partnerships with web design and development firms are evident. The company maintains certifications related to quality management, enhancing trust. Growth indicators include ongoing infrastructure projects and active communication channels. No direct competitors or subsidiaries are identified from the website data.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and a cookie consent mechanism aligned with privacy regulations. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers such as Content Security Policy (CSP), X-Frame-Options, and HSTS suggests room for improvement. No dedicated security or incident response contact information or security.txt file was found, which could enhance transparency and readiness. Overall, the security practices are adequate for a public utility website but could be strengthened to mitigate advanced threats and demonstrate compliance with best practices.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and facilitate vulnerability reporting.
  3. Verify and update WHOIS domain registration information to ensure transparency and trustworthiness.
  4. Regularly audit third-party scripts and libraries for vulnerabilities and update them promptly.
  5. Enhance SEO and accessibility by adding structured data (JSON-LD) for organization and contact information.

The site is mobile-optimized and includes accessibility features such as skip links and ARIA attributes. Performance is moderate with multiple CSS and JS assets loaded, but no major bottlenecks detected. SEO is supported by meta tags, Open Graph tags, and canonical links. The cookie consent mechanism is implemented via a custom script with detailed category management. No server or hosting provider information was identified from the HTML content. The site uses HTTPS with valid certificates, ensuring secure data transmission.
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.
