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

5 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, LinkedIn

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

  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 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';…

  3. 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 company holds a solid position in the Czech financial sector, focusing on building savings and housing finance products. Its business model revolves around providing financial products such as building savings accounts, housing loans, grant consulting, and services for housing cooperatives and legal entities. The website indicates a medium-sized enterprise with a clear target audience in the Czech Republic. The presence of social media channels and a dedicated partner portal suggests an active partnership ecosystem. The content quality and user experience are excellent, supporting customer engagement and trust. The lack of WHOIS data is a minor concern but does not detract significantly from the business credibility.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, cookie consent mechanisms, and form validation including anti-spam measures. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of published security policies, incident response contacts, and security headers such as Content-Security-Policy or X-Content-Type-Options indicates room for improvement. The integration of Sentry for error monitoring is a positive security practice. Overall, the security score is good but could be enhanced by transparency and additional technical controls.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information for security issues.
  3. Implement and enforce security headers like Content-Security-Policy and X-Content-Type-Options.
  4. Regularly audit and update third-party scripts to mitigate vulnerabilities.
  5. Consider establishing a vulnerability disclosure program to encourage responsible reporting.

Technical notes

Notes

The website uses a modern frontend stack with optimized CSS and JavaScript assets, SVG graphics for logos and maps, and asynchronous loading of analytics and consent scripts. Google Tag Manager and Sentry are used for analytics and error tracking respectively. The site is mobile-optimized with responsive design and accessibility features such as skip links and ARIA labels. SEO is supported by proper meta tags and Open Graph data. Performance is moderate, with preloading of fonts and styles. No CMS is explicitly detected, suggesting a custom or proprietary solution by Giant Interactive s.r.o. Hosting provider details are not discernible from the content.
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.
