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

Brněnské komunikace a.s. is a municipal service company providing specialized services for the statutory city of Brno and the general public. Their key offerings include traffic situation monitoring, parking management, road maintenance, construction, smart city initiatives, and coordination of road closures. The company targets local government and citizens, positioning itself as a key municipal infrastructure and transportation service provider in the Czech Republic. The website reflects a medium-sized enterprise with a professional online presence and clear service descriptions. Technically, the website employs modern web technologies including HTML5, CSS3, JavaScript, Google Analytics for visitor tracking, and Cookiebot for cookie consent management. The site is mobile-optimized with good navigation and SEO practices, although no specific CMS or hosting provider was identified. Performance is moderate, and accessibility features are basic but present. From a security perspective, the site uses HTTPS with an excellent SSL configuration and implements cookie consent mechanisms aligned with GDPR requirements. However, it lacks visible security headers and explicit security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the website is trustworthy and professional, though the absence of WHOIS data and privacy policy pages slightly reduces the trust score. Strategic recommendations include publishing privacy and security policies, adding security headers, and providing incident response information to enhance compliance and security posture.

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

4 findings rated critical or high. Fix these first.

  1. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…
  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

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

Brněnské komunikace a.s. operates primarily in the transportation and government sectors, serving the city of Brno. Their business model focuses on providing municipal infrastructure services, including traffic management, parking enforcement, road maintenance, and smart city solutions. The company leverages partnerships with technology providers like Google for analytics and Cookiebot for compliance. The website indicates a stable market position as a local government service provider with a clear target audience. Growth opportunities may lie in expanding smart city initiatives and digital services. The company maintains active social media channels to engage with the community and enhance transparency.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and cookie consent implemented. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a gap that could expose the site to certain web-based attacks. No explicit security or incident response policies are published, which limits transparency and preparedness. Compliance with GDPR is partially evidenced by the cookie consent mechanism but lacks a dedicated privacy policy page in the provided content. There are no visible vulnerabilities or exposed sensitive data. Enhancing security headers and publishing security policies would improve the overall security posture.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a comprehensive privacy policy and terms of service pages accessible from the website footer or header.
  3. Add a security policy and incident response contact information to improve transparency and readiness.
  4. Consider deploying a security.txt file or vulnerability disclosure program to encourage responsible reporting.
  5. Regularly review and update cookie consent and data retention policies to maintain GDPR compliance.

Technical notes

Notes

The website uses a modern tech stack with HTML5, CSS3, JavaScript, and third-party services like Google Analytics and Cookiebot. The site is mobile-optimized and has good SEO metadata including Open Graph and Twitter card tags. No CMS or hosting provider was explicitly identified. Performance is moderate, with some optimization opportunities in accessibility and loading speed. The site uses asynchronous loading for analytics scripts, which is good practice. There is no evidence of technical debt or outdated libraries in the provided content. Overall, the technical implementation supports a professional and functional user experience.
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.
