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

3 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 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

FCC operates in essential sectors including energy, transportation, and real estate, targeting a broad audience including investors, partners, and the general public. The business model focuses on providing integrated services with a strong emphasis on sustainability and corporate governance. The website supports investor relations and corporate communications, indicating a well-established ecosystem. The absence of direct contact emails or phone numbers on the main pages suggests a controlled communication channel, possibly via dedicated portals or forms. The company leverages social media platforms for outreach and engagement.

Security posture

The website enforces HTTPS and employs Google reCAPTCHA to mitigate automated threats. Cookie consent is managed with GDPR compliance, reflecting good privacy practices. However, some standard security headers like X-Frame-Options and X-Content-Type-Options are not explicitly detected, representing an area for improvement. No vulnerabilities or exposed sensitive data were found in the analyzed content. Incident response and vulnerability disclosure information are not publicly available, which could be enhanced to improve transparency and readiness.

Recommendations

  1. Add explicit security headers such as X-Frame-Options and X-Content-Type-Options to strengthen browser security.
  2. Publish a clear incident response and vulnerability disclosure policy to enhance trust and preparedness.
  3. Increase visibility of direct contact information for security and privacy inquiries.
  4. Regularly audit third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Consider implementing security certifications and displaying them to reinforce trust.

Technical notes

Notes

The website utilizes a robust technology stack centered on Liferay CMS, enhanced with Bootstrap for responsive design and React components for interactive elements. Google Analytics and Tag Manager are used for analytics and marketing, with reCAPTCHA protecting forms. The site demonstrates good mobile optimization and accessibility features. Performance is moderate, with potential improvements in resource loading and caching. The technical infrastructure supports a professional and scalable corporate website, though some modernization opportunities exist in security header implementation and performance tuning.
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.
