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
      • 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 holds a market-leading position in the social networking sector, supported by its extensive user base and diversified service offerings including messaging, video, and advertising. Its business model focuses on free user access monetized through targeted advertising and data-driven marketing tools. The company benefits from a strong partnership ecosystem including Instagram, Messenger, and Threads as subsidiaries, all under the parent company Meta. Growth indicators include continuous platform innovation and expansion into new digital services. Competitive advantages stem from its scale, brand recognition, and integrated advertising technologies. The platform targets a broad demographic globally, emphasizing user engagement and business connectivity.

Security posture

Facebook demonstrates a mature security posture with enforced HTTPS, robust SSL configurations, and comprehensive security headers. The use of nonce-based CSP and anti-CSRF tokens in forms indicates strong defenses against common web vulnerabilities. Privacy policies and cookie consent mechanisms align with GDPR requirements, supporting compliance. No immediate vulnerabilities or exposed sensitive data were found. However, public visibility of incident response procedures and vulnerability disclosure programs could be improved to enhance transparency and user trust. The platform's extensive analytics and tracking integrations necessitate ongoing privacy vigilance and data protection efforts.

Recommendations

  1. Maintain continuous security audits and timely patching of all software components.
  2. Increase transparency by publishing detailed incident response and vulnerability disclosure policies.
  3. Enhance user privacy controls and simplify consent mechanisms to improve GDPR compliance.
  4. Expand educational resources to promote security awareness among users and employees.
  5. Develop a long-term security strategy focusing on emerging threats and privacy regulations.

Technical notes

Notes

The website employs a modern technology stack including advanced JavaScript frameworks, BigPipe for optimized content delivery, and nonce-based Content Security Policies for script security. Performance is optimized with preloading of critical resources and asynchronous script loading. Mobile optimization is excellent, with responsive design and alternate mobile URLs. Accessibility features are present but could be further enhanced. The hosting infrastructure is Meta's own, ensuring high availability and scalability. Technical risks are minimal, though continuous monitoring for library vulnerabilities and performance bottlenecks is recommended to maintain operational excellence.
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.
