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

9 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"

      • OWASP A04:2025
      • ASVS V3.4.1
    • 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 company positions itself as a regional real estate developer with a focus on Ostrava and nearby areas, offering commercial office spaces, industrial parks, and land parcels. Their business model revolves around property development and leasing, targeting business clients and investors. The website indicates a stable market presence with professional branding and detailed project portfolios. Partnerships with web development firms like Cyber Fox are evident. The absence of direct phone contacts or social media links suggests a controlled communication approach, possibly emphasizing direct email contact. The company complies with GDPR and cookie regulations, reflecting awareness of regulatory requirements.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and a comprehensive cookie consent mechanism that allows users to manage preferences. However, no explicit HTTP security headers were detected in the provided data, and there is no visible security policy or incident response contact information. The use of somewhat outdated JavaScript libraries (e.g., jQuery 1.11.3) could pose potential vulnerabilities if not regularly updated. No exposed sensitive data or vulnerabilities were found in the HTML content. The site lacks a security.txt file or dedicated vulnerability disclosure policy, which could improve transparency and incident handling readiness.

Recommendations

  1. Implement and enforce HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Regularly update all JavaScript libraries and dependencies to their latest secure versions to mitigate known vulnerabilities.
  3. Publish a clear security policy and incident response contact information to enhance trust and preparedness.
  4. Consider adding a security.txt file and a vulnerability disclosure policy to facilitate responsible reporting.
  5. Enhance accessibility features and conduct periodic security audits to maintain compliance and security posture.

Technical notes

Notes

The website is built on a Bootstrap 3.1.1 framework with jQuery versions 1.11.3 and 2.1.0, supplemented by plugins such as Fancybox and SmartMenus for UI enhancements. Google Maps API integration provides interactive location features. The site uses Foxframe 2.4 as a JavaScript framework. Performance is moderate with responsive design and mobile optimization in place. SEO is supported by proper meta tags and Open Graph data. However, some JavaScript libraries are outdated, and no CMS or hosting provider information is evident. The site could benefit from modernizing its tech stack and improving accessibility compliance.
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.
