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

PostgreSQL.org represents the official website of the PostgreSQL Global Development Group, a mature and highly reputable open source relational database project with over 35 years of active development. The website serves a global audience of developers, database administrators, and open source enthusiasts by providing downloads, documentation, community engagement, and event information. The business model is community-driven open source software development, positioning PostgreSQL as a leading database technology in the industry. Technically, the website employs modern web technologies including Bootstrap, FontAwesome, jQuery, and Google Analytics for tracking. It is well optimized for performance, mobile responsiveness, and accessibility, with clear navigation and professional design. The site uses HTTPS exclusively, ensuring secure communications. However, there is room for improvement in security headers and privacy compliance mechanisms such as cookie consent. From a security perspective, the site demonstrates good practices with secure forms and no visible vulnerabilities or exposed sensitive data. The absence of WHOIS data due to privacy protection is justified given the open source nature and global community focus. No signs of blocking or WAF interference were detected, allowing full content access. The security posture is solid but could be enhanced by publishing explicit security policies and incident response contacts. Overall, PostgreSQL.org is a trustworthy, professional, and authoritative resource for its target audience. Strategic recommendations include enhancing privacy compliance with cookie consent, implementing security headers, and increasing transparency around security policies and incident response to further strengthen trust and security culture.

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

  • 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

PostgreSQL.org operates as the central hub for the PostgreSQL Global Development Group, a large and influential entity in the technology sector specializing in open source database software. The project benefits from a strong community ecosystem, frequent releases, and active event participation, which drive adoption and innovation. The business model relies on open source contributions, community engagement, and providing free software with optional paid support or services through third parties. The website's content and structure reflect a mature organization with clear governance and versioning policies. The absence of direct company contact emails or phone numbers suggests a community-centric rather than commercial sales approach. The use of Google Analytics indicates moderate user tracking for business insights. No suspicious domains or partners were identified, reinforcing the project's independent and community-driven nature.

Security posture

The security posture of PostgreSQL.org is generally strong, with HTTPS enforced site-wide and secure form handling. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the lack of security headers such as Content-Security-Policy and X-Frame-Options represents a missed opportunity to harden the site against common web attacks. The absence of a published security policy or incident response contact reduces transparency for vulnerability reporting. The WHOIS data is unavailable due to privacy protection, which is acceptable for this type of open source project but limits external verification. Overall, the site demonstrates a mature security culture but could improve by formalizing and publishing security policies and enhancing technical defenses.

Recommendations

  1. Implement and publish comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Add a clear cookie consent mechanism to comply with privacy regulations and improve user transparency.
  3. Publish a dedicated security policy page and provide explicit incident response contact information.
  4. Consider adding a security.txt file to facilitate vulnerability disclosure and improve security communication.
  5. Increase visibility of verified company contact emails for security and general inquiries to enhance trust.

Performance is optimized with asynchronous loading of analytics scripts and minimal blocking resources. Accessibility considerations are evident with semantic HTML and form controls. No CMS was detected, suggesting a custom or static site generation approach. Hosting provider details are not disclosed. Overall, the technical implementation supports a fast, accessible, and user-friendly experience with opportunities to enhance security headers and privacy features.
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.
