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

Superapartments 24, operated by VANDERBERG MEDIA SE, is a professional real estate platform specializing in apartment listings for sale and rent primarily in the UK and international markets. The website offers a comprehensive suite of services including legal assistance, advertising packages for estate agencies, mortgage support, and personal assistance with property inspections. The platform targets estate agencies, private sellers, buyers, and renters, positioning itself as a trusted intermediary with exclusive offers and partnerships. The business is relatively new, founded in 2022, and operates from the Czech Republic with a medium-sized company profile. Technically, the website is built on modern frameworks such as Next.js and React, leveraging Cloudflare for DNS and CDN services. It integrates Google Tag Manager for analytics, Google reCAPTCHA v3 for bot protection, and CookieYes for cookie consent management, reflecting a mature digital infrastructure. The site is mobile optimized with good SEO and accessibility features, although some accessibility aspects could be enhanced. From a security perspective, the site enforces HTTPS and employs standard security practices including bot mitigation and cookie consent. However, DNSSEC is not enabled, and no security.txt or explicit incident response contacts are published, representing areas for improvement. The WHOIS data is transparent and consistent with the business profile, enhancing trustworthiness. Overall, the security posture is good but could be strengthened with additional DNS and policy measures. The website is safe for general audiences, containing no adult or questionable content. It maintains GDPR compliance with clear privacy and cookie policies and provides multiple contact channels. The overall risk is low, with strategic recommendations focusing on enhancing DNS security, publishing vulnerability disclosure policies, and improving security headers to further solidify 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. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Cloudflare, Google APIs

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

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

Superapartments 24 operates in the competitive real estate market, leveraging a digital-first approach to connect estate agencies and private sellers with buyers and renters. Its partnership ecosystem includes legal and construction firms, enhancing service breadth. The business model centers on advertising and service fees, targeting a broad audience including international clients. Growth indicators include recent domain registration and active job postings. The company maintains a professional online presence with consistent branding and comprehensive service offerings, positioning it as a reliable player in the real estate portal sector.

Security posture

The website demonstrates a solid security foundation with HTTPS enforcement, bot protection via Google reCAPTCHA, and cookie consent mechanisms. However, the absence of DNSSEC and security.txt files, along with missing explicit security headers, indicates room for improvement. No exposed sensitive data or vulnerable libraries were detected. Incident response readiness is not publicly documented, which could hinder rapid mitigation of security incidents. Compliance with GDPR is evident, but enhancing transparency around security policies and incident handling would strengthen the security culture and trust.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and prevent spoofing.
  2. Publish a security.txt file to provide clear vulnerability disclosure and incident response contacts.
  3. Implement additional security headers such as X-Frame-Options and X-Content-Type-Options to mitigate common web attacks.
  4. Provide explicit incident response contact information on the website to enhance transparency and readiness.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, ensuring server-side rendering and good SEO performance. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The integration of Google Tag Manager and reCAPTCHA indicates mature analytics and security practices. Performance is moderate with room for optimization, particularly in accessibility and mobile responsiveness. The site uses a custom CMS or framework rather than a common CMS like WordPress, indicating tailored development. Overall, the technical infrastructure supports a professional and scalable real estate platform.
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.
