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

2 findings rated critical or high. Fix these first.

  1. 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

      SSL Certificate Expires Soon

      SSL certificate expires in 7 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Facebook's business model is primarily advertising-driven, leveraging extensive user data and analytics to deliver targeted ads. The company operates at an enterprise scale with a global audience and a diverse portfolio of subsidiaries including Instagram, Messenger, and Threads. Its competitive advantage lies in its massive user base, integrated ecosystem, and advanced data analytics capabilities. The website's external links and references to Meta's other services indicate a tightly integrated partnership ecosystem. The absence of direct contact information on the main page is typical for large platforms relying on support portals and automated systems. Facebook's market presence is strong, with continuous innovation and expansion into new technologies such as AI and virtual reality.

Security posture

Facebook exhibits a mature security posture with HTTPS enforced site-wide, presence of key security headers like Content-Security-Policy and Strict-Transport-Security, and no visible exposure of sensitive data. The site uses secure forms for user login and data submission. No known vulnerabilities or outdated libraries were detected in the analyzed content. Privacy and cookie policies are comprehensive, indicating strong compliance efforts. However, no explicit incident response or vulnerability disclosure pages were found, which is common for large enterprises that handle these through dedicated channels. Continuous security monitoring and regular audits are recommended to maintain this posture given the platform's scale and threat profile.

Recommendations

  1. Implement and publicize a dedicated vulnerability disclosure or bug bounty page to enhance transparency and security collaboration.
  2. Provide clearer and more accessible security incident response contact information for improved trust and responsiveness.
  3. Regularly update and audit third-party libraries and scripts to mitigate potential vulnerabilities.
  4. Enhance accessibility features to ensure compliance with latest standards and improve user inclusivity.
  5. Maintain and update privacy and cookie consent mechanisms to adapt to evolving regulations and user expectations.

Technical notes

Notes

The website employs a modern tech stack centered around React and Relay frameworks, with extensive use of JavaScript and CSS for dynamic content rendering. The infrastructure is optimized for performance with asynchronous script loading and resource preloading. Mobile optimization is excellent, with alternate mobile URLs and responsive design elements. SEO is supported by proper meta tags, Open Graph protocol, and JSON-LD structured data. Hosting is managed by Meta's own infrastructure, ensuring high availability and scalability. No CMS was detected, indicating a custom-built platform. Technical risks are minimal but require ongoing management of third-party dependencies and continuous performance monitoring.
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.
