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

Advantage Consulting, s.r.o., operating the website www.acjobs.cz, is a leading Czech personnel agency established in 2002. The company specializes in helping job seekers find employment and offers recruitment services to employers. The website reflects a professional business model targeting both job seekers and companies within the Czech Republic, positioning itself as the largest personnel agency in the country. The site provides a broad range of job offers and related content, including blogs and partner employer listings. Technically, the website employs a modern technology stack including Vue.js, Bootstrap, jQuery, and various JavaScript libraries for enhanced user experience and interactivity. It is mobile-optimized with good SEO practices and uses HTTPS to secure communications. The presence of cookie consent mechanisms and privacy policies indicates a commitment to GDPR compliance and user privacy. From a security perspective, the site demonstrates good practices such as HTTPS enforcement, CSRF token usage, and cookie management. However, explicit security policies and incident response information are not publicly available, which could be improved. No critical vulnerabilities or security issues were detected in the analysis. Overall, the website is trustworthy and professional, though the absence of WHOIS data limits domain registration transparency. Strategic recommendations include enhancing security headers, publishing a formal security policy, and improving WHOIS data visibility to strengthen trust and compliance further.

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

6 findings rated critical or high. Fix these first.

  1. 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 holds a strong market position as the largest personnel agency in the Czech Republic, focusing on recruitment and job placement services. Its business model revolves around connecting job seekers with employers, supported by a network of partner companies and regional offices. The website content and partner logos indicate a well-established ecosystem and a medium-sized enterprise. The company leverages digital marketing tools and social media channels to engage its audience. Growth indicators include a large number of job offers and active content updates. The partnership with A-WebSys for website development suggests a professional approach to digital presence.

Security posture

The security maturity level of the website is moderate to good. HTTPS is properly implemented, and cookies include security tokens to prevent CSRF attacks. The cookie consent banner and privacy policy demonstrate GDPR awareness. However, the lack of explicit security policies, incident response contacts, and security.txt files indicates room for improvement in transparency and readiness. No vulnerable libraries or exposed sensitive data were detected. The site could benefit from additional HTTP security headers such as Content-Security-Policy and X-Frame-Options to mitigate common web attacks. Overall, the security posture supports business operations but should be enhanced to meet higher compliance standards.

Recommendations

  1. Implement and enforce Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options HTTP headers.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Regularly audit and update third-party libraries to mitigate vulnerabilities.
  4. Improve WHOIS data transparency or ensure domain registration details are publicly accessible.
  5. Enhance accessibility features and conduct periodic security assessments to maintain compliance.

Technical notes

Notes

The website uses a combination of modern front-end technologies including Vue.js for reactive UI components, Bootstrap for responsive design, and jQuery for legacy support. It integrates third-party services such as Facebook SDK, Google Tag Manager, and Smartsupp Chat for analytics and customer engagement. The site loads multiple CSS and JS resources efficiently, though performance is moderate likely due to the number of external scripts. Mobile optimization is good, with responsive navigation and layout adjustments. The absence of a detected CMS suggests a custom or proprietary platform. Technical risks include dependency on multiple third-party scripts and the need for enhanced security headers.
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.
