Real Estate · Poland
Medium risk. 6 critical or high findings in GDPR outside view, Security headers and 2 other checks.
Nieruchomosci-online.pl is a prominent Polish real estate portal offering a comprehensive platform for buying, selling, and renting properties including apartments, houses, plots, and commercial spaces. The website targets a broad audience including individual buyers, renters, real estate agents, and developers, positioning itself as one of the largest property listing services in Poland with over 350,000 listings. The business model revolves around providing direct listings from owners, agencies, and developers, supplemented by tools such as a financial calculator and agent finder to enhance user experience. Technically, the website employs modern web technologies including jQuery, Google Tag Manager, and Mapbox for mapping services. The site is well-optimized for desktop and mobile devices, with good SEO practices and a professional design. Performance is moderate, with room for improvement in accessibility features. The site uses HTTPS exclusively, ensuring encrypted communications. From a security perspective, the site demonstrates good baseline practices such as HTTPS enforcement and cookie consent mechanisms aligned with GDPR. However, it lacks explicit security headers like Content-Security-Policy and does not provide visible contact points for security incidents or vulnerability disclosures. The absence of publicly available WHOIS data due to privacy protection is common but slightly reduces transparency. Overall, the website is a credible and professional real estate portal with a solid technical foundation and moderate security posture. Strategic improvements in privacy policy visibility, security headers, and incident response transparency would enhance trust and compliance.
Scanned
NIS2 Art. 21(2)
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.

Each check with its score, findings and the evidence it collected.

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.
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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
