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.

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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

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

  3. 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';…

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 website serves as a niche real estate portal for the Domažlice district, leveraging partnerships with local real estate agencies and agents. Its business model relies on listing fees and advertising revenue, supported by Google Adsense and local ad networks. The platform targets local buyers, sellers, and renters, providing detailed filtering options and up-to-date listings. The presence of multiple partner domains and a parent company indicates a stable operational ecosystem. Growth potential lies in expanding listings and enhancing user engagement through content and marketing tools. The company benefits from a recognized brand in the Czech real estate market, although the lack of public WHOIS data may affect trust for some users.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and use of consent management for cookies, indicating GDPR awareness. However, it lacks advanced security headers such as Content-Security-Policy and does not publish security or incident response policies. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a security.txt file and vulnerability disclosure process suggests limited formal security governance. Overall, the site is secure for typical user interactions but could improve transparency and resilience by adopting additional security best practices and publishing relevant policies.

Recommendations

  1. Implement additional HTTP security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure and improve security posture.
  4. Enhance accessibility features to comply with WCAG standards for broader user inclusivity.
  5. Consider publishing terms of service and data retention policies to strengthen legal compliance and user awareness.

Technical notes

Notes

The website uses a combination of modern JavaScript libraries and frameworks including jQuery, Vue.js, and various UI components such as multiple-select and flatpickr for date inputs. Google Analytics and Google Tag Manager are integrated for analytics and marketing. The site loads CSS and JS assets with versioning for cache control. Performance is moderate with lazy loading of images and asynchronous loading of scripts. Mobile optimization is good with responsive images and viewport settings. The site does not appear to use a common CMS, suggesting a custom or proprietary platform. Hosting provider details are not explicitly found. Technical debt appears low, but opportunities exist to improve security headers 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.
