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

The website www.e-zamestnani.cz operates as a specialized online platform providing job listings and career information for government offices and municipalities in the Czech Republic. It is managed by Rentel a.s., a company with a physical presence in Prague. The platform targets job seekers interested in public sector employment, offering curated links and information about career opportunities at regional and city government offices. The website uses WordPress with the Divi theme, integrating GDPR-compliant cookie consent mechanisms and analytics tools such as Google Tag Manager and Burst Statistics. The design is professional and mobile-optimized, providing a good user experience with clear navigation and relevant content. Security posture is adequate with HTTPS enforced and cookie consent implemented, but lacks advanced security headers and explicit security policies. The absence of WHOIS data for the domain reduces confidence in domain legitimacy, although the website content and contact information appear trustworthy. Overall, the site is functional and compliant with privacy regulations but would benefit from enhanced security practices and transparency regarding domain registration and terms of service.

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

  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 business model focuses on providing a niche service connecting job seekers with public sector employment opportunities in the Czech Republic. Rentel a.s. leverages its expertise to aggregate and present official career pages of government offices, positioning itself as a trusted intermediary in this market segment. The platform's competitive advantage lies in its specialization and localized content. Revenue streams likely include advertising or partnerships with government entities. The target customer segment is clearly defined as individuals seeking government jobs. The partnership ecosystem includes related domains such as rentel.cz, which is the parent company. Growth indicators include recent content updates and active cookie compliance. Strategic observations suggest opportunities to expand services or integrate more interactive job application features.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and GDPR cookie consent implemented. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options indicates room for improvement. No visible vulnerabilities or exposed sensitive data were detected in the HTML content. The site does not provide explicit incident response or vulnerability disclosure information, which could hinder rapid response to security incidents. Compliance with GDPR is evident through cookie management and privacy policy presence. Overall, the security culture appears basic but functional, with recommendations to enhance header configurations and publish security policies.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  2. Publish a clear terms of service and security policy page to enhance transparency and legal compliance.
  3. Add a security.txt file and vulnerability disclosure policy to facilitate responsible reporting of security issues.
  4. Regularly update WordPress core, themes, and plugins to mitigate risks from known vulnerabilities.
  5. Enhance accessibility features to meet compliance standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on WordPress CMS using the Divi theme, a popular and flexible framework for content management. It employs jQuery and integrates Google Tag Manager and Burst Statistics for analytics and tracking. The site uses the Complianz GDPR plugin for cookie consent management, indicating attention to privacy compliance. Performance is moderate with responsive design and mobile optimization evident. However, the absence of advanced security headers and incomplete WHOIS data suggest technical debt and potential risks. Hosting provider details are not disclosed. The site structure and SEO elements are well implemented, but accessibility could be improved. Overall, the technical infrastructure is solid but would benefit from modernization in security and transparency 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.
