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

The website www.e-zamestnani.cz serves as a specialized job listing and career information platform focused on public sector employment opportunities within the Czech Republic. Operated by Rentel a.s., it targets job seekers interested in government and municipal positions, providing curated listings and direct links to career pages of various Czech government offices. The site demonstrates a consistent and professional brand presence with clear navigation and relevant content tailored to its niche audience. Technically, the site is built on WordPress using the Divi theme, supplemented by common plugins such as Complianz GDPR for cookie consent management and Burst Statistics for analytics. The infrastructure supports HTTPS with good SSL configuration, though additional security headers could enhance its security posture. Performance and mobile optimization are adequate, ensuring a positive user experience across devices. From a security and compliance perspective, the site enforces HTTPS and provides comprehensive privacy and cookie policies aligned with GDPR requirements. Contact information is clearly presented, enhancing business credibility. However, the absence of WHOIS data for the domain raises concerns about domain registration transparency, which slightly impacts trustworthiness. No critical vulnerabilities or exposed sensitive data were detected in the content. Overall, the website presents a secure, compliant, and user-friendly platform for its target audience, though verifying domain registration details and enhancing security headers would strengthen its trust profile and resilience against potential threats.

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. 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

  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 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 occupies a niche market segment by focusing exclusively on public sector employment within the Czech Republic, differentiating itself from general job boards. Its business model revolves around aggregating and linking to official government career pages, likely generating revenue through service contracts or partnerships with public institutions. The presence of Rentel a.s. as the parent company suggests a medium-sized enterprise with expertise in digital services for government clients. The website's clear contact details and privacy compliance indicate a mature operational approach. Growth potential exists through expanding partnerships with additional government offices or integrating advanced job matching technologies. The ecosystem includes trusted analytics and GDPR compliance tools, supporting data-driven insights and regulatory adherence.

Security posture

The website exhibits a solid security foundation with enforced HTTPS and cookie consent mechanisms that comply with GDPR standards. No security headers were explicitly detected, which is an area for improvement to mitigate risks such as clickjacking or MIME sniffing. The absence of exposed credentials or vulnerable libraries in the HTML content is positive. However, the lack of WHOIS data for the domain is a notable gap that could indicate registration issues or privacy protection that is not justified by the business type. Incident response and security policy documentation are not present, suggesting limited transparency in security governance. Overall, the security posture is good but could benefit from enhanced header implementation and clearer incident response protocols.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security to strengthen defense against common web attacks.
  2. Verify and update domain WHOIS registration details to improve transparency and trustworthiness.
  3. Establish and publish a formal security policy and incident response plan accessible to users and partners.
  4. Regularly audit and update WordPress core, themes, and plugins to mitigate vulnerabilities and maintain compliance.
  5. Enhance accessibility features to improve usability for all users and comply with accessibility standards.

Technical notes

Notes

The website leverages a modern CMS platform (WordPress) with the Divi theme, providing a flexible and visually appealing design. The use of jQuery and Google Tag Manager indicates standard web technologies for interactivity and analytics. Performance is moderate, with responsive design elements ensuring usability on mobile devices. The site employs GDPR-compliant cookie management via the Complianz plugin, reflecting attention to privacy regulations. However, the absence of advanced security headers and incomplete WHOIS data suggest areas for technical improvement. Hosting details are not explicitly identified, limiting full infrastructure assessment. Overall, the technical implementation supports the business goals but would benefit from security and transparency enhancements.
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.
