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 global social media leader is reinforced by its extensive ecosystem including Instagram, Messenger, and Threads. Its business model revolves around free user access monetized through advertising and data services. The company benefits from strong brand recognition, a large user base, and diversified services. Growth is supported by continuous innovation in AI and payment technologies (Meta Pay). Partnerships and subsidiaries are tightly integrated, enhancing user engagement and monetization opportunities. The platform's extensive tracking and analytics capabilities support targeted advertising and business intelligence.

Security posture

Facebook exhibits a mature security posture with enforced HTTPS, secure cookie attributes, and anti-CSRF protections on forms. The absence of exposed sensitive data and use of modern JavaScript frameworks reduce attack surface. Privacy policies and cookie consent mechanisms align with GDPR requirements. However, no explicit public incident response or vulnerability disclosure pages were found, suggesting room for improved transparency. The domain's privacy-protected WHOIS is justified given the company's size and risk profile. Overall, the platform is secure but should maintain vigilance against emerging threats and enhance public security communications.

Recommendations

  1. Maintain continuous security audits and timely patching of all web components.
  2. Establish and publicize a dedicated vulnerability disclosure program and incident response contacts.
  3. Enhance transparency around data protection officer contacts and security certifications.
  4. Regularly update privacy and cookie consent mechanisms to reflect evolving regulations.
  5. Invest in user education on privacy settings and security best practices to strengthen trust.

Technical notes

Notes

The website leverages a modern tech stack including React and BigPipe for dynamic content delivery and performance optimization. The use of asynchronous JavaScript loading and CSS preloading improves page load times. Hosting is likely on Meta's proprietary infrastructure, ensuring scalability and reliability. The site is mobile-optimized with responsive design and accessibility features. No CMS was detected, indicating a custom-built platform. Technical risks are minimal but require ongoing management of third-party scripts and tracking technologies to avoid privacy and security issues.
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.
