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

The website portal.dtm-praha-sck.cz serves as the official portal for the Digital Technical Map (DTM) of Prague and the Central Bohemian Region. Operated by the Institute of Planning and Development of the Capital City of Prague, it provides access to public data packages, documentation, data validation tools, metadata, georeports, and statistics related to the digital technical map. The portal is positioned as a central hub for government entities, municipalities, and infrastructure managers, supported by European Union funding and national recovery plans. Technically, the site is built on modern frameworks such as Nuxt.js and Vue.js, with PrimeVue components and Tailwind CSS for styling, ensuring a responsive and accessible user experience. Security posture is strong with HTTPS enforcement, security headers, and CAPTCHA integration, although explicit security policies and incident response contacts are not published. The absence of WHOIS data is a notable gap, but the website's content and official affiliations suggest legitimacy. Overall, the portal demonstrates a mature digital infrastructure supporting government geospatial data services.

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

7 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

  2. 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';…

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 portal targets government agencies, municipalities, and technical infrastructure managers in Prague and the Central Bohemian Region, offering essential services for managing and accessing digital technical map data. Its business model is public sector-focused, funded by EU and national programs, emphasizing data provision and regulatory compliance support. The portal's integration with partner sites like the Central Office for Surveying, Mapping and Cadastre (ČÚZK) and regional geoportals strengthens its market position. The lack of direct contact emails or phone numbers suggests a controlled communication channel, likely via contact forms. The portal's content quality and professional design reflect a well-established service with strategic importance in regional planning and infrastructure management.

Security posture

The website employs HTTPS with good SSL configuration and includes multiple security headers enhancing protection against common web vulnerabilities. The use of Turnstile CAPTCHA indicates proactive bot mitigation. However, the absence of a publicly available security policy, vulnerability disclosure program, or incident response contact reduces transparency and preparedness perception. No exposed sensitive data or vulnerable libraries were detected in the analysis. The security score is solid but could be improved by publishing formal security documentation and providing explicit security contact channels.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear incident response contact information, including security-specific emails.
  4. Enhance contact information availability with verified company emails and phone numbers.
  5. Regularly review and audit third-party scripts and dependencies for security vulnerabilities.

Technical notes

Notes

The portal is built using modern web technologies including Nuxt.js and Vue.js frameworks, leveraging PrimeVue UI components and Tailwind CSS for styling. The site is mobile responsive and optimized for accessibility and SEO, with structured data (JSON-LD) implemented for enhanced search engine understanding. Performance is moderate, with preloading and prefetching of scripts observed. Google Tag Manager and Google Analytics are used for analytics and tracking, balanced with a cookie consent mechanism for privacy compliance. No CMS or hosting provider details were explicitly identified. The technical stack supports a professional and scalable platform suitable for government digital services.
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.
