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 operates as a core asset of Meta, leveraging a business model centered on advertising revenue generated through extensive user engagement. Its market positioning as a technology giant is reinforced by its ownership of subsidiaries like Instagram, Messenger, and Threads. The platform targets a general audience worldwide, offering a suite of interconnected social media and communication services. Facebook's ecosystem includes partnerships and integrations with various marketing and analytics tools, enhancing its advertising capabilities. The company's strategic focus on user data monetization and platform expansion underpins its competitive advantage and growth trajectory.

Security posture

Facebook demonstrates a mature security posture with enforced HTTPS, use of security headers such as HSTS and Content-Security-Policy, and secure cookie attributes. The site employs nonce-based script loading to mitigate cross-site scripting risks. No vulnerabilities or exposed sensitive data were detected in the analyzed content. However, public incident response and vulnerability disclosure information are not directly available on the main site, suggesting an area for transparency improvement. Overall, Facebook maintains strong security best practices aligned with industry standards.

Recommendations

  1. Enhance public visibility of incident response and vulnerability disclosure policies to improve transparency.
  2. Maintain continuous monitoring and updating of third-party libraries to prevent vulnerabilities.
  3. Regularly audit privacy compliance to adapt to evolving regulations such as GDPR and NIS2.
  4. Increase user awareness and control over data collection and tracking mechanisms.
  5. Strengthen communication channels for security incidents and user support.

Technical notes

Notes

Facebook's technical infrastructure is built on a modern tech stack including React, extensive JavaScript, and CSS frameworks. The site is optimized for fast loading and mobile responsiveness, with accessibility considerations evident. Use of JSON-LD structured data and Open Graph tags supports SEO and social media integration. The hosting environment and CDN usage are implied but not explicitly identified. Performance is fast with well-structured code and asynchronous script loading. Technical risks are minimal, with opportunities for further modernization in transparency and incident response integration.
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.
