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

City24.ee is a prominent Estonian online real estate platform offering property listings and market information primarily targeting Estonian property buyers, sellers, and renters. The website employs a modern React-based frontend with integrations of Mapbox for mapping, Google Fonts, and multiple third-party analytics and advertising services including Facebook Pixel, Gemius, and Google Tag Manager. The technical infrastructure reflects a contemporary digital maturity with good mobile optimization and moderate performance. Security posture is solid with HTTPS enforced and use of Google reCAPTCHA v3 to mitigate automated abuse; however, the absence of security headers and formal privacy or cookie policies indicates room for improvement in security best practices and compliance. The website lacks explicit contact information and formal policies, which impacts user trust and privacy compliance. Overall, the site is functional and professional but would benefit from enhanced transparency and security hardening.

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

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

Business profile

City24.ee operates as a leading real estate marketplace in Estonia, focusing on property listings and related services. Its business model revolves around providing a digital platform for real estate transactions and market insights. The target audience includes individual buyers, sellers, renters, and real estate professionals within Estonia. The presence of a related domain (ao.city24.lv) suggests a regional partnership or expansion. The company appears to be a large entity within the Estonian real estate sector, though specific founding year and corporate structure details are not available. The platform leverages advertising and analytics extensively, indicating revenue streams from ad placements and possibly premium listings. The lack of visible trust indicators such as certifications or testimonials suggests an opportunity to strengthen market credibility.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and bot mitigation via Google reCAPTCHA v3. However, the absence of critical security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the provided content. The lack of published security policies, incident response contacts, or vulnerability disclosure mechanisms indicates gaps in compliance and incident readiness. Extensive use of third-party tracking and advertising scripts increases the attack surface and privacy risks. Overall, the security posture is adequate but requires enhancements to meet higher compliance and security standards.

Recommendations

  1. Implement comprehensive privacy and cookie policies with explicit user consent mechanisms to improve GDPR compliance.
  2. Add standard security headers (CSP, HSTS, X-Content-Type-Options, X-Frame-Options) to strengthen security posture.
  3. Publish clear contact information including security incident response contacts to enhance trust and readiness.
  4. Conduct regular security audits of third-party scripts and minimize tracking to reduce privacy risks.
  5. Improve accessibility features and provide more comprehensive content to enhance user experience and SEO.

Technical notes

Notes

The website uses a modern React framework with asynchronous loading of scripts and styles, including Mapbox GL JS for interactive maps and Google Fonts for typography. Analytics and advertising integrations are extensive, including Facebook Pixel, Gemius, Google Tag Manager, and Google Ads conversion tracking. The site loads multiple JavaScript bundles and CSS files, indicating modular frontend architecture. Performance is moderate with deferred script loading and asynchronous resource fetching. Mobile optimization is good, but accessibility features are basic. No CMS or hosting provider information was detected. The technical stack is contemporary but could benefit from improved SEO metadata and 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.
