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

Penziony.cz is an established Czech online platform specializing in affordable accommodation listings including pensions, hotels, apartments, and cottages. Operated by eViz s.r.o., it targets travelers seeking budget-friendly lodging options across the Czech Republic. The website offers extensive listings with direct contact details to properties, facilitating user bookings and searches. Technically, the site is built on WordPress using the WP Rentals theme, integrating modern JavaScript libraries such as jQuery, Bootstrap, Algolia Places, and Mapy.cz APIs for enhanced user experience and search functionality. Security-wise, the site employs HTTPS and nonce tokens for form submissions, indicating a baseline security posture; however, it lacks comprehensive security headers and explicit incident response policies. Privacy compliance is partial, with a privacy policy present but no visible cookie consent mechanism, which may pose GDPR compliance risks. The absence of WHOIS data limits domain trust assessment, but the website content and business information appear professional and trustworthy. Overall, Penziony.cz presents a solid digital presence in the hospitality sector with room for improvement in privacy and security transparency.

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. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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 platform holds a strong market position as a comprehensive accommodation directory in the Czech Republic, serving a broad audience of travelers. Its business model revolves around listing properties and enabling direct contact between guests and property owners, possibly monetized through listing fees or premium services via its partner domain eshop.penziony.cz. The integration with booking and image hosting services like p.zarezervovat.cz suggests a partnership ecosystem supporting its operations. The company maintains consistent branding and good content quality, which supports user trust and engagement. Growth potential lies in expanding service offerings and enhancing compliance and security features to meet evolving regulatory standards.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and secure form handling via nonce tokens. However, it lacks critical security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate common web vulnerabilities. No evidence of vulnerability disclosure or incident response policies was found, indicating potential gaps in security governance. The absence of cookie consent mechanisms also raises privacy compliance concerns under GDPR. While no immediate vulnerabilities or exposed sensitive data were detected, the site would benefit from enhanced security controls and transparency to strengthen its security culture and readiness.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Deploy a visible cookie consent banner to ensure GDPR compliance and user privacy awareness.
  3. Publish clear security and incident response policies, including a vulnerability disclosure program or security.txt file.
  4. Enhance WHOIS domain registration transparency or verify domain registration details to improve trustworthiness.
  5. Regularly audit third-party libraries and APIs for vulnerabilities and update them to latest secure versions.

Technical notes

Notes

The website leverages a mature WordPress CMS platform with a specialized rental theme, integrating multiple modern JavaScript libraries and APIs for maps and search functionality. Performance is moderate with room for optimization, especially in accessibility and SEO enhancements. Mobile optimization is good, ensuring usability across devices. The technical stack is standard for hospitality listing platforms but would benefit from improved security configurations and privacy features. Hosting provider details are not disclosed, which could be relevant for infrastructure risk assessment. Overall, the technical infrastructure supports the business needs but requires modernization in security and compliance aspects.
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.
