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

Statutární město Opava operates an official municipal website providing comprehensive information and services to residents, visitors, and local businesses. The site serves as a central hub for news, public administration details, event calendars, and contact information, positioning itself as a trusted government resource in the Czech Republic. The website leverages modern web technologies including WebJET CMS, Bootstrap, Leaflet.js for mapping, and integrates Google Analytics and Tag Manager for analytics and marketing purposes. It demonstrates good digital maturity with responsive design, accessibility features, and SEO optimizations. Security posture is adequate with HTTPS enforced and cookie consent mechanisms in place, though there is room for improvement in HTTP security headers and incident response transparency. The absence of WHOIS data slightly impacts trust but the official branding and content quality strongly support legitimacy. Overall, the site is a well-maintained government portal with moderate technical sophistication and good privacy 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

The website reflects a medium-sized government entity focused on serving the Opava community. Its business model is centered on public service delivery and information dissemination. The site supports multiple sectors including social services, culture, transportation, and urban planning. It maintains active communication channels and social media presence, enhancing community engagement. The extensive menu structure and content depth indicate a mature digital presence. Partnerships with external platforms like Google and social media networks support marketing and outreach efforts. The lack of WHOIS transparency is a minor concern but does not detract from the site's official status. Growth indicators include regular news updates and strategic project disclosures.

Security posture

The website enforces HTTPS and implements GDPR-compliant cookie consent, reflecting a baseline security posture. However, no explicit HTTP security headers were detected in the provided data, suggesting potential gaps in defense-in-depth strategies. The site uses third-party scripts such as Google Analytics and Tag Manager, which require ongoing monitoring for vulnerabilities. There is no visible incident response or vulnerability disclosure information, which could be improved to enhance security readiness. No exposed sensitive data or known vulnerabilities were identified. Overall, the security maturity is moderate but could benefit from enhanced header policies, security.txt adoption, and clearer incident response contacts.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a security.txt file to facilitate vulnerability reporting and improve transparency.
  3. Enhance incident response readiness by providing dedicated security contact channels (e.g., security@ or abuse@ email addresses).
  4. Regularly audit and update third-party scripts to mitigate risks from external dependencies.
  5. Continue to maintain and improve GDPR compliance and cookie consent mechanisms to build user trust.

Technical notes

Notes

The website is built on WebJET CMS with Bootstrap framework and uses Leaflet.js for interactive maps. It integrates Google Tag Manager and Google Analytics for tracking and marketing. The site is mobile responsive and includes accessibility features such as ARIA labels and keyboard navigation aids. Performance is moderate, with video content and multiple JavaScript libraries potentially impacting load times. SEO is supported by structured data (JSON-LD) and Open Graph metadata. There is no explicit hosting provider information. The site uses modern web standards but could improve by optimizing script loading and enhancing security headers. Overall, the technical infrastructure supports a robust municipal portal with opportunities for modernization 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.
