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

7 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 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

    • 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

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

Redarbor's market position as the second largest global employment site group and leader in Latin America is supported by its portfolio of well-known brands such as Computrabajo, Infojobs, Catho, and OCC. The business model focuses on digital recruitment and HR software solutions, targeting job seekers and employers. The company demonstrates strong growth and social commitment, emphasizing helping people find better jobs and companies recruit top talent. Its partnership ecosystem includes multiple subsidiary domains and platforms, enhancing its market reach. The presence of certifications and awards like Great Place To Work and ISO 27001 further reinforce its credibility and operational excellence.

Security posture

The company exhibits a strong security posture with ISO 27001 certification and implementation of cookie consent mechanisms. The website uses HTTPS and modern security practices, with no exposed sensitive data or vulnerable libraries detected. However, the absence of DNSSEC and a publicly available security.txt or incident response contact are areas for improvement. The security headers and domain status clientTransferProhibited add to the domain's protection. Overall, Redarbor shows a mature security culture aligned with industry standards but could enhance transparency in vulnerability disclosure and incident management.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Provide explicit incident response contact information (e.g., security@ or abuse@ email).
  4. Regularly review and update third-party scripts and libraries to avoid vulnerabilities.
  5. Enhance data retention transparency in privacy policies to improve user trust.

Technical notes

Notes

The website is built using modern JavaScript libraries and frameworks, including AOS for animations, GLightbox for media, and Didomi for consent management. Google Tag Manager and Piano Analytics are used for tracking and analytics. Hosting is on AWS, inferred from DNS nameservers. The site is mobile-optimized, accessible, and SEO-friendly with proper meta tags and Open Graph data. Performance is moderate, with room for optimization. No CMS is explicitly detected, suggesting a custom or proprietary platform. The technical stack supports a professional and scalable digital presence aligned with the company's business needs.
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.
