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

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

The company operates in the real estate sector, focusing on software and digital services tailored for real estate agencies, agents, and developers. Their business model revolves around software development and service provision, including multi-listing services and web presence solutions. The company maintains partnerships with several related domains offering complementary services, indicating a collaborative ecosystem. The firm is small-sized with a long operational history, enhancing credibility. The website content and linked services suggest a stable revenue stream from software subscriptions and web services. The absence of social media presence and limited marketing tools indicates a focused, possibly niche market approach. The company provides clear legal and contact information, reinforcing trust and compliance with local regulations.

Security posture

The website employs HTTPS (assumed from modern standards though not explicitly stated), but lacks visible security headers such as Content Security Policy, HSTS, or X-Frame-Options. No incident response or security policy pages are present, and no vulnerability disclosure or security.txt files were found. The site uses third-party libraries like jQuery and Alpine.js, which require regular updates to mitigate vulnerabilities. No forms are present on the main page, reducing attack surface, but cookie consent mechanisms are missing despite cookie policy presence, which may be a GDPR compliance gap. Overall, the security posture is moderate but could be significantly improved by implementing security headers, explicit incident response information, and cookie consent mechanisms.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Add a cookie consent banner/mechanism to comply fully with GDPR and improve user privacy transparency.
  3. Publish explicit security policy and incident response information to improve trust and readiness.
  4. Regularly audit and update third-party libraries to mitigate vulnerabilities.
  5. Enhance analytics and marketing transparency by disclosing tracking and data collection practices.

Technical notes

Notes

The website uses a modern frontend stack with Tailwind CSS for styling, Alpine.js for reactive components, and jQuery for DOM manipulation. Chartist.js is included for charting capabilities, and a custom money formatting script is used. The site is responsive and mobile-optimized with good design quality and navigation clarity. No CMS or backend platform is detected from the HTML content. Hosting provider details are not disclosed. Performance is moderate, likely due to multiple external scripts and large images. Accessibility is basic with some semantic HTML usage but no ARIA landmarks or advanced accessibility features detected. SEO optimization is basic with meta charset and viewport tags but no Open Graph or structured data found. Overall, the technical implementation is solid but could benefit from enhanced SEO and accessibility improvements.
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.
