NIS2 Art. 21(2)

  1. (a) Risk analysis and security policies: Not visible from outside
  2. (b) Incident handling: One indicator
  3. (c) Business continuity, backups and crisis management: Not visible from outside
  4. (d) Supply chain security: Not visible from outside
  5. (e) Secure acquisition, development and maintenance, including vulnerability handling: Partly checked
  6. (f) Assessing the effectiveness of security measures: Not visible from outside

  8. (h) Cryptography and encryption: Partly checked
  9. (i) HR security, access control and asset management: One indicator
  10. (j) Multi-factor authentication and secured communications: Not visible from outside

The NIS2 figure counts only evidence anyone can see from the internet. 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

No critical or high findings. These medium findings are worth fixing next.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Medium

      MTA-STS Policy Invalid

      The _mta-sts TXT record exists but the policy cannot be used: https://mta-sts.cloudflare.com/.well-known/mta-sts.txt could not be fetched. Senders that honour MTA-STS may defer mail.

      What to do: Serve a valid policy (version: STSv1, mode, mx, max_age) over HTTPS with a trusted certificate at https://mta-sts.cloudflare.com/.well-known/mta-sts.txt.

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.
  • Accessibility: Accessibility is a separate readout from security, so it is reported but not scored. 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

Cloudflare holds a strong market position as a critical internet infrastructure provider, with a business model focused on subscription and service-based revenue streams. The company targets enterprises, developers, and organizations requiring enhanced security and performance for their online assets. The presence of verified social media links and structured data supports its credibility. While explicit privacy and terms of service documents are not directly found, the overall branding and technical sophistication indicate a mature and well-established operation with a global footprint.

Security posture

The website enforces HTTPS with excellent SSL configuration and implements multiple security headers, indicating a strong security posture. Integration with consent management platforms like OneTrust and Zaraz demonstrates compliance efforts. No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms suggests areas for improvement in transparency and incident readiness. Overall, the security maturity is high but could benefit from enhanced documentation and communication.

Recommendations

  1. Publish and prominently link a comprehensive privacy policy and terms of service to improve privacy compliance and user trust.
  2. Provide clear contact information including dedicated security incident response and abuse contacts to enhance incident management readiness.
  3. Implement and publicize a vulnerability disclosure program or security.txt file to foster responsible security reporting.
  4. Regularly audit and update third-party libraries and tracking tools to mitigate potential vulnerabilities.
  5. Enhance transparency around certifications and compliance frameworks to strengthen trust and market positioning.

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.
