0–100, higher is better. How it is calculated

CloudNativePG is an open source Kubernetes operator designed to manage highly available PostgreSQL clusters with native streaming replication. The project is community-driven and originally created by EnterpriseDB, now under LF Projects, LLC. It targets Kubernetes users and DevOps professionals seeking automated, cloud native PostgreSQL lifecycle management. The website presents comprehensive technical content describing features such as autopilot deployment, data persistence, security, high availability, disaster recovery, monitoring, and advanced architectures. The site is well structured, mobile optimized, and uses modern technologies including Hugo and Google Analytics. Security posture is good with HTTPS and no exposed sensitive data, though explicit security headers and policies are missing. Privacy and cookie policies are absent, indicating compliance gaps. WHOIS data is consistent and transparent, supporting legitimacy. Overall, the website is professional and trustworthy but could improve privacy compliance and security disclosures.

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

9 findings rated critical or high. Fix these first.

  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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

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

CloudNativePG occupies a niche in the cloud native database operator market, focusing on PostgreSQL on Kubernetes. Its open source model with Apache 2 license encourages community contributions and adoption. The project benefits from EnterpriseDB's initial development and Linux Foundation stewardship, enhancing credibility. The business model centers on community-driven development with potential enterprise support. Target customers include cloud native developers, database administrators, and DevOps teams. The partnership ecosystem includes EnterpriseDB and Linux Foundation. Growth indicators include recent domain registration and active GitHub presence. The website content supports technical decision makers evaluating Kubernetes database solutions.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no visible sensitive data leaks. The product supports TLS encryption, client authentication, and auditing features. However, the website lacks published privacy and cookie policies, security.txt, and incident response contacts, which are important for compliance and trust. No security headers were detected in the HTML. Google Analytics is used without a consent mechanism, raising privacy concerns. No forms or inputs reduce attack surface. Overall, security maturity is good but could be enhanced by formal policies and headers.

Recommendations

  1. Publish comprehensive privacy and cookie policies to improve GDPR compliance.
  2. Implement a cookie consent mechanism to inform users about tracking.
  3. Add security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  4. Provide a security.txt file or vulnerability disclosure policy with contact information.
  5. Include contact details or a dedicated security contact email for incident response.

Technical notes

Notes

The website is built using the Hugo static site generator, ensuring fast performance and good SEO. It uses Google Fonts and Google Analytics for typography and analytics respectively. Hosting is likely on AWS based on DNS nameservers. The site is mobile responsive with clear navigation and consistent branding. No CMS vulnerabilities or outdated libraries were detected. The absence of forms reduces risk exposure. The technical stack aligns well with the target audience of Kubernetes and PostgreSQL users. Opportunities exist to improve security headers and privacy compliance to reduce risk and enhance trust.
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.
