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.

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

What to do: Implement SPF, DKIM, and DMARC immediately
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.

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.

Business context
Business profile
PSN s.r.o. is a medium-sized real estate developer with a strong market position in Prague, focusing on residential property sales with direct ownership and financing facilitation. The business model emphasizes direct sales without commission, supported by partnerships with mortgage brokers. The company maintains multiple related project domains, indicating a diversified portfolio. The target audience includes local buyers and investors seeking quality housing in a historic and green Prague neighborhood. The website content and structure support lead generation and customer engagement effectively.
Security posture
The website employs HTTPS and integrates Google reCAPTCHA v3 to protect form submissions, enhancing security against automated abuse. Cookie consent mechanisms align with GDPR requirements. However, the absence of explicit security headers such as Content Security Policy and HSTS reduces defense-in-depth. No incident response or vulnerability disclosure information is provided, which could hinder timely security issue reporting. No vulnerabilities or exposed sensitive data were detected in the content. Overall, the security posture is good but could be improved with additional headers and published policies.
Recommendations
Implement HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance browser security.
Publish a clear security policy and incident response contact information on the website.
Add a security.txt file to facilitate vulnerability reporting and improve transparency.
Enhance accessibility features to meet higher compliance standards and improve user experience for all visitors.
Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.
Automated reading of the public site. Ratings are indicative.

Technical notes
Notes
The website uses a modern and popular technology stack with Bootstrap 5.3.2 for responsive design, Swiper for interactive galleries, and LightGallery for image viewing. Google Maps API integration provides location context. Google Tag Manager and Seznam tracking scripts enable analytics and marketing. Hosting is provided by websupport.cz, indicated by the nameservers. Performance is moderate with good mobile optimization. SEO is supported by proper meta tags and Open Graph data. No CMS was explicitly detected, suggesting a custom or static site build. The site could benefit from improved accessibility and additional security headers.
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.
