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

Reality Karlovy Vary is a regional real estate listing platform focused on the Karlovy Vary district in the Czech Republic. Operated by ČESKÝ INTERNET s.r.o., the site aggregates property listings for sale and rent, including residential, commercial, and land properties. It also provides directories of real estate agencies and brokers, along with relevant real estate news articles. The platform targets individuals and businesses seeking real estate in the region, positioning itself as a trusted local marketplace. Technically, the website employs a modern tech stack including jQuery, Vue.js, Google Analytics, and a consent management platform. It is mobile-optimized with good SEO practices and uses HTTPS for secure communications. The site integrates multiple advertising and tracking services, maintaining a balance between user experience and marketing needs. From a security perspective, the site enforces HTTPS and basic security headers but lacks advanced headers like Content-Security-Policy and security.txt for vulnerability disclosure. No critical vulnerabilities or exposed sensitive data were detected. Privacy compliance is well addressed with a privacy policy and cookie consent mechanism. However, the absence of phone contact details and terms of service pages slightly reduces business credibility. Overall, Reality Karlovy Vary presents a professional and trustworthy online presence for real estate services in its region. The main risk factor is the absence of WHOIS data, which limits domain registration trust verification. Strategic improvements in security headers, incident response transparency, and additional contact channels would enhance trust and compliance.

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';…

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 platform operates in the real estate sector, focusing on the Karlovy Vary district. Its business model revolves around aggregating listings from real estate agencies and private sellers, monetized likely through advertising and premium listings. The presence of numerous partner agencies and brokers indicates a strong local partnership ecosystem. The company, ČESKÝ INTERNET s.r.o., appears to be a medium-sized entity with a history dating back to at least 2008. The website's content and structure suggest a mature digital presence with steady user engagement. The lack of direct phone contacts may indicate a preference for digital communication channels. The site’s integration with multiple ad networks and tracking services supports revenue generation through targeted advertising.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is enforced, and basic security headers are present, but advanced headers like Content-Security-Policy and Strict-Transport-Security are missing. The use of a consent management platform aligns with GDPR requirements, and privacy policies are published. No exposed credentials or vulnerable libraries were detected in the HTML content. However, the absence of a security.txt file and incident response information indicates limited transparency in vulnerability management. The site uses multiple third-party scripts, which should be regularly audited to mitigate supply chain risks. Overall, the security posture is adequate for a real estate listing platform but could be improved with enhanced headers and documented security policies.

Recommendations

  1. Implement advanced security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to strengthen browser security.
  2. Publish a security.txt file and incident response policy to improve transparency and facilitate vulnerability reporting.
  3. Add clear phone contact numbers for customer support to enhance business credibility and user trust.
  4. Develop and publish terms of service and security policy pages to clarify user rights and security commitments.
  5. Regularly audit third-party scripts and dependencies to identify and mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a combination of jQuery and Vue.js for frontend interactivity, supported by multiple plugins for UI components such as multiple select dropdowns, date pickers, and carousels. Google Analytics and Tag Manager are used for analytics and marketing tracking. The site is served over HTTPS with a responsive design optimized for mobile devices. Performance is moderate, with lazy loading of images and asynchronous loading of scripts to improve load times. The absence of a detected CMS suggests a custom or proprietary platform. The site includes a cookie consent mechanism compliant with GDPR. Technical risks include reliance on multiple third-party scripts and incomplete security header implementation, which could be addressed to improve overall robustness.
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.
