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

Ostravacard.eu is a website promoting the OSTRAVACARD!!! visitor discount card for tourists staying in Ostrava, Czech Republic. The card is distributed free of charge by selected accommodation providers for stays of at least two nights and offers various discounts and benefits at partner locations. The website is professionally designed with a focus on tourism and hospitality, featuring partner logos from recognized Czech tourism organizations. Technically, the site uses modern frontend technologies including Bootstrap, jQuery, Flickity carousel, Leaflet maps, and Google Analytics for visitor tracking. The site is served over HTTPS and implements a cookie consent mechanism with opt-in for analytics cookies, indicating a basic level of privacy compliance. However, no explicit privacy policy or terms of service pages were found, and no direct contact information is provided on the homepage, which limits transparency. WHOIS data is privacy protected by EURid, which is typical for EU domains and does not raise immediate concerns. Overall, the website presents a legitimate, small-scale tourism promotion business with moderate technical maturity and a generally good 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

10 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

    • High

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 business operates in the hospitality sector, targeting tourists visiting Ostrava. Its business model revolves around providing a physical discount card that grants benefits at partner venues, thus encouraging tourism and local spending. The company, Černá louka s.r.o., appears to be a small entity focused on local market positioning with partnerships including official city and tourism organizations. The website content and partner ecosystem suggest a stable presence in the regional tourism market. Revenue streams likely include partnerships and promotional collaborations. The absence of detailed company registration or VAT information on the site limits deeper business intelligence. Growth indicators include regular updates and new benefits. The partnership ecosystem is strong with recognized tourism bodies, enhancing credibility.

Security posture

The website demonstrates a basic but adequate security posture. HTTPS is enforced, and cookie consent is implemented with opt-in for analytics cookies, aligning with GDPR principles. However, no security headers such as Content-Security-Policy or X-Frame-Options were detected, which could improve protection against common web attacks. No sensitive data exposure or vulnerable libraries were identified in the provided content. The lack of a published security policy or incident response contact reduces transparency and preparedness. Overall, the site is moderately secure but would benefit from enhanced security headers, explicit privacy documentation, and incident response information to improve trust and compliance.

Recommendations

  1. Implement and publish a comprehensive privacy policy page linked prominently on the website.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Provide clear contact information including emails and phone numbers for general and security-related inquiries.
  4. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Develop and communicate an incident response plan and vulnerability disclosure policy to build user trust.

Technical notes

Notes

The website uses a modern frontend stack with Bootstrap for responsive design, jQuery for DOM manipulation, Flickity for carousel functionality, and Leaflet.js for interactive maps. Google Tag Manager and Google Analytics are used for tracking user behavior. The site is mobile optimized and has good SEO metadata including Open Graph tags. No CMS or backend technology was identified from the HTML content. Performance is moderate with multiple external resources loaded from CDNs. Accessibility is basic with some ARIA roles used in the cookie consent modal. The site lacks advanced security headers and explicit privacy/legal pages, which are technical debt areas. Hosting provider details are not disclosed. Overall, the technical infrastructure is adequate for a small tourism promotion site but could be improved with enhanced security and privacy features.
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.
