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

Reality Písek is a regional real estate listing platform focused on the Písek district in the Czech Republic. Operated by ČESKÝ INTERNET s.r.o., the website aggregates property listings for sale and rent, including residential, commercial, and land properties. It also features directories of real estate agencies and brokers, serving individuals and businesses seeking real estate in the region. The platform positions itself as a trusted local resource with a professional presentation and a broad network of partners. Technically, the website employs modern web technologies including jQuery, Vue.js, Google Analytics, and Google Tag Manager. It is mobile-optimized with good SEO practices and includes a cookie consent mechanism compliant with GDPR. Performance is moderate with asynchronous loading of scripts and lazy loading of images. However, some security headers are not explicitly detected, suggesting room for improvement in security hardening. From a security perspective, the site enforces HTTPS and implements cookie consent, but lacks visible security policies or incident response contacts. WHOIS data is unavailable due to privacy protection or query issues, but the domain appears legitimate and well-maintained. No vulnerabilities or exposed sensitive data were detected. Overall, the security posture is solid but could benefit from enhanced security headers and published security policies. The overall risk assessment is low, with the website demonstrating professionalism, compliance with privacy regulations, and a clear business model. Strategic recommendations include implementing additional security headers, publishing a security policy, and adding a vulnerability disclosure mechanism to further enhance trust and security.

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

8 findings rated critical or high. Fix these first.

  1. 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

  2. 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';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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 targeting the Písek district, leveraging partnerships with multiple local real estate agencies and brokers. Its business model is based on aggregating listings and providing advanced search capabilities to end users. The presence of a parent company, ČESKÝ INTERNET s.r.o., indicates an established operator with experience in internet services. The platform's competitive advantage lies in its regional focus and comprehensive property filtering options. Revenue streams likely include advertising, featured listings, and partnerships with real estate agencies. The target customers are local buyers, sellers, renters, and real estate professionals. Growth indicators include regular content updates and integration with partner sites. The partnership ecosystem includes realitniservery.cz and other local agencies, enhancing market reach and credibility.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and cookie consent mechanisms are implemented, indicating compliance with GDPR. However, the absence of explicit security headers such as Content-Security-Policy and Strict-Transport-Security suggests potential areas for improvement. No exposed sensitive data or vulnerable libraries were detected. The lack of a published security policy or incident response contact limits transparency in security management. There is no evidence of a security.txt file or vulnerability disclosure program. Overall, the security posture is adequate for the business type but could be strengthened by adopting additional best practices and publishing security-related information to build user trust and readiness for incident response.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Add a security.txt file to facilitate vulnerability disclosure and improve transparency.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance privacy compliance by detailing data retention policies and user rights in the privacy policy.

Technical notes

Notes

The website uses a modern technology stack with Vue.js and jQuery for frontend interactivity, Google Analytics and Tag Manager for tracking, and AppConsent for cookie management. The site is mobile-optimized and uses lazy loading for images, improving performance. However, no CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not available. The site loads asynchronously and uses multiple external scripts, which may impact load times but are managed to maintain moderate performance. Accessibility is basic, with room for improvement in ARIA roles and semantic markup. SEO is well addressed with proper meta tags and Open Graph data. Overall, the technical infrastructure is solid but could benefit from enhanced accessibility and security header implementation.
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.
