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

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 market positioning as a social media giant is reinforced by its extensive ecosystem including Instagram, Messenger, and Threads. Its business model is primarily advertising-driven, supported by advanced tracking and marketing tools. The company targets a broad general audience worldwide, with a focus on connectivity and social interaction. Strategic partnerships and subsidiaries enhance its service offerings and market reach. The website's content and branding are consistent and professional, supporting strong user engagement and trust. Growth indicators include continuous technological innovation and expansion of services under the Meta umbrella.

Security posture

The website exhibits a mature security posture with HTTPS enforced and HSTS implemented, reducing risks of man-in-the-middle attacks. Security headers and secure cookie attributes are present, though explicit incident response contacts and vulnerability disclosure mechanisms are not publicly visible on the homepage. No critical vulnerabilities or exposed sensitive data were detected in the analysis. Privacy policies and cookie consent mechanisms indicate compliance with major data protection regulations. The absence of a security.txt or explicit incident response page suggests room for improvement in transparency and user guidance during security incidents.

Recommendations

  1. Publish a dedicated security or incident response page with clear contact channels.
  2. Implement and publicize a vulnerability disclosure or bug bounty program.
  3. Enhance transparency around data retention and user data handling practices.
  4. Regularly update and audit third-party libraries to mitigate potential vulnerabilities.
  5. Improve visibility of privacy and security certifications to strengthen user trust.

Technical notes

Notes

Facebook's website is built on a modern tech stack including React and Relay, enabling efficient data fetching and UI rendering. The use of Shaka Player indicates advanced video streaming capabilities. The site is optimized for performance with asynchronous script loading and CSS preloading. Accessibility features and SEO optimizations are well implemented, supporting broad user access and search engine visibility. Hosting details are not explicitly disclosed but the infrastructure supports enterprise-level traffic and resilience. Technical risks are minimal, with continuous updates and monitoring likely in place given the scale and importance of the platform.
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.
