0–100, higher is better. How it is calculated

Facebook, operated by Meta Platforms, Inc., is a leading global social networking platform that enables users to connect, share content, and communicate. It holds a dominant market position with a vast user base and offers key services including social networking, messaging, video content, and advertising. The website is professionally designed with excellent content quality and consistent branding, targeting a general audience worldwide. The platform integrates with its parent company Meta and subsidiaries such as Instagram, Messenger, and Threads, forming a comprehensive social media ecosystem. Technically, Facebook employs a modern and robust technology stack including React, Relay, and BigPipe, hosted on Meta's infrastructure. The site demonstrates excellent performance, mobile optimization, and accessibility, ensuring a seamless user experience across devices. Security is strong with HTTPS enforcement, secure cookie policies, and content security measures, although no explicit security policy or incident response contact is publicly listed on the homepage. Privacy compliance is well addressed with comprehensive privacy and cookie policies, including GDPR adherence and consent mechanisms. However, direct contact information such as emails or phone numbers for support or security are not explicitly provided on the main page. WHOIS data is unavailable due to registry restrictions, a common practice for large brands to protect privacy, but the domain's legitimacy is unquestioned given its global recognition and consistent content. Overall, Facebook's website reflects a mature digital presence with strong business credibility, technical sophistication, and security posture. Strategic recommendations include maintaining up-to-date security practices, enhancing transparency around security policies and incident response, and continuing to monitor third-party integrations for vulnerabilities.

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 8 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

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 operates as a dominant player in the social media industry, leveraging its extensive user base and integration with Meta's family of apps to maintain competitive advantages. Its business model centers on user engagement and targeted advertising, generating significant revenue streams. The platform targets a broad demographic globally, focusing on social connectivity and digital communication. Growth is supported by continuous innovation and expansion into new services such as video and AI-driven features. Partnerships and subsidiaries like Instagram and Messenger enhance its ecosystem, providing cross-platform synergies. The company's operations reflect a high level of digital maturity and market penetration.

Security posture

Facebook exhibits a high security maturity level with enforced HTTPS, secure cookie attributes, and modern web security practices. The presence of HSTS and nonce-based script loading indicates strong defenses against common web attacks. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the absence of publicly visible security policies or incident response contacts on the homepage suggests room for improvement in transparency and user trust. Compliance with GDPR and cookie consent mechanisms is evident, supporting regulatory adherence. Overall, Facebook maintains a robust security posture appropriate for its scale and risk profile.

Recommendations

  1. Publish a dedicated security policy and incident response contact information prominently on the website.
  2. Regularly audit and update third-party libraries and integrations to mitigate potential vulnerabilities.
  3. Enhance transparency around data protection officer contact details and vulnerability disclosure programs.
  4. Maintain and improve cookie consent mechanisms to align with evolving privacy regulations.
  5. Invest in continuous security awareness and culture initiatives to strengthen organizational security posture.

Technical notes

Notes

The website leverages a sophisticated technical infrastructure with React and Relay frameworks, enabling dynamic and responsive user interfaces. BigPipe technology is used for efficient page loading, improving performance. Hosting is managed on Meta's own infrastructure, ensuring scalability and reliability. The site is optimized for mobile devices and accessibility, with comprehensive SEO meta tags and structured data (JSON-LD) for enhanced search engine understanding. No CMS was detected, indicating a custom-built platform. Performance is fast with asynchronous script loading and resource preloading. Technical risks are minimal but require ongoing management of third-party dependencies.
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.
