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

Statutární město Opava operates an official municipal website serving as the primary digital platform for city residents, visitors, and local businesses. The site provides comprehensive information about city governance, public services, news, events, and contact details. It targets a broad audience including citizens, municipal employees, and tourists, positioning itself as a trusted source of local government information. The business model is that of a government service portal, focusing on transparency and community engagement. Technically, the website employs modern web technologies including HTML5, CSS3, JavaScript with jQuery, Bootstrap framework, and mapping libraries like Leaflet.js. It uses WebJET CMS for content management and integrates Google Tag Manager and Google Analytics for tracking and analytics. The site is mobile-optimized, accessible, and SEO-friendly, with structured data enhancing search engine understanding. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms aligned with GDPR requirements. However, it lacks explicit privacy policy and terms of service pages, security headers, and incident response contacts, which are areas for improvement. No vulnerabilities or malicious content were detected, and the site maintains a good security posture overall. Overall, the website is a professional and trustworthy municipal portal with good content quality and technical implementation. The absence of WHOIS data limits domain transparency, but the official branding and comprehensive contact information support its legitimacy. Strategic recommendations include publishing privacy and security policies, enhancing security headers, and providing incident response contacts to strengthen compliance and trust.

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. 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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

The website represents the statutory city government of Opava, Czech Republic, serving as a central hub for municipal information and services. It holds a strong market position as the official digital presence of the city administration. The business model is focused on public service delivery and community engagement rather than commercial revenue. Key services include public notices, event calendars, municipal department contacts, and access to official documents. The target customer segments are local residents, businesses, and visitors. The site demonstrates growth indicators through regular updates and integration of digital tools. Partnerships are evident with social media platforms and mapping services, enhancing outreach and usability.

Security posture

The security maturity level of the website is moderate. HTTPS is enforced, and cookie consent mechanisms are in place, indicating awareness of privacy regulations. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No explicit incident response or vulnerability disclosure channels are provided, which could delay response to security incidents. Data protection practices are partially implemented but lack transparency due to missing privacy policy documentation. The site does not expose sensitive data or use vulnerable libraries visibly. Overall, the security culture appears basic but could benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Publish a comprehensive privacy policy page clearly linked from the website footer or header.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security.
  3. Establish and publicize incident response contact information or a security@ email address for vulnerability reporting.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance cookie consent details to include granular user choices and data retention information.

Technical notes

Notes

The website is built on a modern technology stack featuring HTML5, CSS3, JavaScript with jQuery, and Bootstrap for responsive design. It uses WebJET CMS, which supports structured content management. Mapping functionality is provided via Leaflet.js and OpenStreetMap integration. Analytics and tag management are handled through Google Analytics and Google Tag Manager. The site demonstrates good mobile optimization and accessibility features. Performance is moderate, with potential improvements in script loading and caching. Technical debt appears low, but modernization opportunities include adopting security headers and improving privacy compliance mechanisms. The infrastructure supports stable operation but lacks visible hosting provider details.
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.
