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

OstravaInfo is an official city guide portal providing comprehensive information about Ostrava, including events, tourist attractions, and local services. It serves both tourists and local visitors with detailed event calendars, tourist information centers, and an e-shop for souvenirs. The website is well-positioned as a trusted source for Ostrava-related information, supported by partnerships with local organizations and government entities. Technically, the website uses a traditional web stack with jQuery, Google Tag Manager, and Facebook Pixel for analytics and marketing. The site is mobile-optimized and provides a good user experience with clear navigation and relevant content. However, there is no detected CMS or advanced frameworks, indicating a possibly custom or legacy implementation. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms, demonstrating compliance with privacy regulations such as GDPR. However, the absence of explicit security headers and lack of visible incident response or security policy pages suggest areas for improvement. The WHOIS data is missing, which raises concerns about domain registration transparency and trustworthiness. Overall, OstravaInfo presents a professional and trustworthy front for tourism information but should enhance its security posture and domain registration transparency to strengthen trust and 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.

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

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

      • OWASP A04:2025
      • ASVS V3.4.1

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

OstravaInfo operates as an important entity in the hospitality and government tourism sector, focusing on providing official information and event listings for Ostrava. Its business model revolves around content provision and e-commerce through souvenir sales. The site benefits from strong local partnerships and a clear target audience of tourists and residents. The lack of detailed financial or founding data limits deeper business insights, but the presence of multiple information centers and active social media channels indicates a stable operational presence. The portal's competitive advantage lies in its official status and comprehensive local coverage. Revenue streams likely include e-shop sales and possibly partnerships or sponsorships. Growth indicators include active event updates and multilingual support via related domains. Strategic observations suggest maintaining and expanding partnerships and improving digital infrastructure to enhance user engagement and trust.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforcement and cookie consent compliance. The use of Google Analytics and Facebook Pixel is standard but requires ongoing monitoring for privacy compliance. The absence of security headers like Content-Security-Policy and X-Frame-Options is a gap that could expose the site to certain attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. There is no public incident response or security contact information, which is a compliance gap. GDPR compliance is indicated by the privacy policy and cookie consent mechanisms. Overall, the security posture is adequate for the site's purpose but could be improved by implementing additional security headers, publishing a security policy, and establishing incident response contacts.

Recommendations

  1. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and provide incident response contact information to improve transparency and compliance.
  3. Verify and update WHOIS domain registration information to ensure domain legitimacy and trust.
  4. Regularly audit third-party scripts and tracking tools to minimize privacy risks and maintain GDPR compliance.
  5. Enhance accessibility features and conduct periodic security assessments to maintain a strong security culture.

Technical notes

Notes

The website uses a traditional JavaScript stack with jQuery and jQuery UI components, along with third-party analytics and marketing scripts such as Google Tag Manager and Facebook Pixel. The site is mobile-optimized with responsive design and includes a cookie consent mechanism. Performance appears moderate, with no explicit indicators of slow loading but also no advanced optimization techniques detected. No modern CMS or frameworks were identified, suggesting a custom or legacy build. The site uses standard HTML5 and CSS with some inline styles for cookie consent. Hosting provider details are not evident from the content. Technical risks include potential outdated libraries and lack of advanced security headers. Opportunities exist to modernize the tech stack, improve performance, and enhance security configurations.
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.
