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

Zamestnani.cz is a Czech Republic-based online job portal operated by Tanger s.r.o., providing a comprehensive platform for job seekers and employers to connect. The website offers job listings, temporary work opportunities, and career advice, targeting the Czech labor market. It holds a solid market position as a recognized job listing service in the region. Technically, the site is built on ASP.NET WebForms with modern front-end technologies including Bootstrap 5, jQuery, and Select2, ensuring a responsive and user-friendly experience. The site integrates Google services such as Tag Manager and Adsense, with a clear consent mechanism for privacy compliance. Security-wise, the website enforces HTTPS and basic security headers, though it could improve by adding advanced headers and HSTS. No critical vulnerabilities or exposed sensitive data were detected. The absence of WHOIS data due to privacy protection slightly reduces transparency but is common for commercial websites. Overall, Zamestnani.cz demonstrates a good balance of business functionality, technical implementation, and privacy awareness.

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

    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

      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

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 business operates in the employment services sector, focusing on the Czech market. Its business model revolves around aggregating and listing job offers and temporary work, monetized likely through advertising and possibly premium employer services. The target audience includes job seekers across various professions and employers seeking candidates. The company Tanger s.r.o. is the legal entity behind the site, though no parent or subsidiary companies were identified. The website's content quality and branding are consistent, supporting a professional image. The platform leverages partnerships with Google for analytics and advertising, indicating a mature digital marketing approach. Growth potential lies in expanding job categories and enhancing user engagement through career advice content.

Security posture

The website maintains a good security posture with HTTPS enforced and a cookie consent mechanism that respects user privacy preferences. Security headers are present but limited, suggesting room for enhancement. No signs of malware, phishing, or exposed credentials were found. The use of third-party scripts is controlled with consent, reducing privacy risks. However, the lack of advanced security headers and no visible incident response or security policy pages indicate potential gaps in formal security governance. Compliance with GDPR is implied through consent management but not explicitly documented. Overall, the security maturity is moderate with recommendations to strengthen header policies and publish security-related documentation.

Recommendations

  1. Implement additional HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security (HSTS).
  2. Publish a clear privacy policy and terms of service pages accessible from the homepage to improve transparency and compliance.
  3. Add visible contact information including company emails and phone numbers to enhance business credibility and user trust.
  4. Establish and disclose an incident response policy and vulnerability disclosure program to demonstrate security readiness.
  5. Regularly audit and update third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a mature technology stack based on ASP.NET WebForms, enhanced with modern front-end libraries like Bootstrap 5 and jQuery. It loads Google Fonts and integrates Google Tag Manager and Adsense for analytics and advertising. The site is mobile responsive and optimized for SEO with proper meta tags and structured data (JSON-LD). Performance is moderate, with some scope for optimization in loading times and accessibility features. The use of multiple viewstate fields indicates a complex page state management typical for WebForms. No CMS was detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. Overall, the technical infrastructure supports the business needs but could benefit from modernization and enhanced security configurations.
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.
