  3. (c) Business continuity, backups and crisis management: Not visible from outside
  4. (d) Supply chain security: Not visible from outside

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.

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

  • SSL/TLS: did not complete in this scan.
  • Email security: did not complete in this scan.
  • DNS health: did not complete in this scan.
  • Network security: did not complete in this scan.
  • 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

Confluent operates in the technology sector, focusing on data streaming and real-time data processing. Their competitive advantage lies in leveraging open-source technologies like Apache Kafka and Flink, combined with enterprise-grade features and cloud-native architecture. Revenue streams likely include software subscriptions, support, and professional services. The target customer segments are large enterprises requiring scalable data infrastructure. Growth indicators include extensive partnerships, certifications, and a strong brand presence. The company maintains a robust partnership ecosystem and invests in marketing and analytics tools to support customer acquisition and retention.

Security posture

Confluent's security maturity is high, evidenced by HTTPS enforcement, comprehensive security headers, and industry-standard certifications. No exposed sensitive data or vulnerable libraries were detected. Compliance with GDPR is indicated by detailed privacy and cookie policies with consent mechanisms. However, the lack of a public incident response contact or vulnerability disclosure policy represents a compliance gap. The company should consider publishing a security policy and establishing clear channels for security incident reporting to enhance readiness and trust.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Establish and publicize a vulnerability disclosure program or security.txt file.
  3. Provide explicit incident response contact information for security issues.
  4. Regularly review and update privacy and cookie policies to maintain GDPR compliance.
  5. Enhance transparency around data retention policies and user data handling.

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.
