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

4 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. 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

Docler Holding operates as a diversified holding company with subsidiaries spanning streaming and entertainment, health and wellness, philanthropy, venture capital, technology services, sports, and hospitality. Its market position is strong, supported by a long domain history and a broad portfolio of brands. The company targets business partners, investors, and job seekers, with active recruitment and social media engagement. The business model focuses on managing and growing a varied set of companies under a unified brand. The website content and structure support clear communication of its offerings and corporate culture, enhancing credibility and market presence.

Security posture

The website demonstrates a good security baseline with HTTPS enforced and domain status locks to prevent unauthorized changes. Cookie consent is implemented, indicating awareness of privacy regulations. However, the absence of DNSSEC and lack of published security policies or incident response contacts represent areas for improvement. No vulnerabilities or exposed sensitive data were detected in the content. The use of modern web technologies reduces risk from outdated components. Overall, the security posture is solid but could benefit from enhanced transparency and additional technical controls.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing.
  2. Publish a dedicated security policy and incident response information to improve transparency and trust.
  3. Consider implementing a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  4. Review and add additional HTTP security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from vulnerable libraries.

Technical notes

Notes

The website is built on a modern technology stack including Next.js and React, providing server-side rendering and optimized performance. The CMS appears to be Strapi, indicated by the admin subdomain and API structure. The site is mobile-optimized with responsive design and good accessibility features. SEO is supported by comprehensive meta tags and Open Graph data. Hosting details are limited but the domain registrar is EuroDNS S.A. Performance is fast with deferred script loading and preloading of critical CSS. No major technical debt or outdated technologies were observed, indicating a well-maintained infrastructure.
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.
