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

Starjob.cz is a Czech Republic-based AI-powered recruitment platform operated by Active Radio a.s. It offers personalized job matching for candidates and AI-driven candidate screening for employers, aiming to streamline recruitment and improve job fit. The platform integrates modern web technologies such as React, Next.js, and Material-UI, hosted on Microsoft Azure, ensuring a fast and responsive user experience. Privacy compliance is strong, with GDPR-aligned policies and cookie consent mechanisms clearly implemented. Security posture is good with HTTPS and security headers, though explicit security policy and incident response information are absent. WHOIS data is unavailable, likely due to local registry privacy policies, which slightly impacts transparency but does not detract from the professional presentation and trustworthiness of the site.

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 company positions itself as an innovative player in the Czech recruitment market, leveraging AI to reduce time and cost for employers while enhancing job seeker experience. Its business model revolves around providing AI-enhanced job search and recruitment tools, targeting both job seekers and employers. The platform's partnership with Dream Jobs and integration with related domains like business.dream.jobs and muj.starjob.cz indicates a broader ecosystem supporting recruitment services. The company appears medium-sized with a focus on technology and recruitment sectors, emphasizing GDPR compliance and user data protection as competitive advantages.

Security posture

The website employs HTTPS with strong SSL configuration and security headers, indicating a mature security posture. Cookie consent and privacy policies demonstrate compliance with data protection regulations. However, the absence of a dedicated security policy page, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of reputable analytics and tracking services is balanced with privacy considerations.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and frameworks.
  2. Provide explicit incident response contact information for security issues.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Enhance WHOIS transparency if possible or provide domain registration details on the site.
  5. Continue to monitor and update privacy compliance as regulations evolve.

Technical notes

Notes

The site is built on a modern React/Next.js stack with Material-UI for UI components, ensuring a responsive and accessible design. Hosting on Azure Container Apps provides scalability and reliability. Performance is optimized with preloading of key assets and use of Google Fonts. Analytics integration includes Microsoft Clarity and Facebook Pixel, supporting user behavior insights. The site is mobile-optimized and SEO-friendly with appropriate meta tags and Open Graph data. No CMS detected, likely a custom or headless architecture. Overall, the technical implementation supports a professional and user-friendly recruitment platform.
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.
