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

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

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

Aventin Shopping holds a strong regional position in retail real estate development in the Czech Republic. Their business model revolves around developing, leasing, and managing retail parks. The company targets retail customers and tenants seeking retail space in strategic locations. The website highlights multiple retail locations with detailed addresses and images, indicating a focus on physical retail presence. The company uses various marketing and analytics tools to optimize user engagement and advertising effectiveness. No direct contact emails or phone numbers are provided on the homepage, which may limit direct customer engagement online.

Security posture

The website enforces HTTPS and implements a comprehensive cookie consent mechanism compliant with GDPR. Multiple third-party analytics and marketing scripts are used, with user consent controls in place. However, the site lacks visible security headers such as Content-Security-Policy and X-Frame-Options, which could enhance protection against common web attacks. No security.txt or vulnerability disclosure policy is found, and no explicit incident response contacts are provided. The absence of WHOIS data limits domain transparency but is likely due to privacy protection. Overall, the security posture is good but could be improved with additional headers and disclosure policies.

Recommendations

  1. Implement security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  2. Publish a security.txt file to facilitate vulnerability reporting and improve transparency.
  3. Add explicit contact information for security incidents and data protection officer details.
  4. Regularly audit third-party scripts and plugins for vulnerabilities and update them promptly.
  5. Enhance website accessibility features to meet compliance standards and improve user experience.

Technical notes

Notes

The website is built on WordPress 6.8.2 with common plugins such as Yoast SEO and Dynamic Cookies Bar Pro. It uses jQuery and Slick Carousel for UI components. The site loads multiple third-party analytics and marketing scripts, including Google Analytics, Facebook Pixel, Hotjar, and Microsoft Clarity.

Hosting provider details are not explicitly found. Overall, the technical infrastructure is modern and suitable for the business needs.
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.
