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

The PostgreSQL website represents the official online presence of The PostgreSQL Global Development Group, a large and well-established open source community focused on developing and maintaining one of the world's most advanced open source relational database systems. The site provides comprehensive resources including downloads, documentation, community engagement, and event information, targeting developers, database administrators, and organizations seeking robust database solutions. The business model centers on open source software development supported by a global community, with a strong market position as a leading database technology. Technically, the website employs modern web technologies such as Bootstrap, FontAwesome, and Google Analytics, ensuring a responsive and user-friendly experience. The site is well-structured with good SEO and accessibility practices, and it loads quickly. Security is robust with HTTPS enforced and secure form handling, although explicit security headers are not visible in the HTML content. Privacy compliance is partially addressed with a comprehensive privacy policy and terms of service, but lacks a visible cookie consent mechanism. From a security perspective, the site demonstrates good practices including encrypted connections and no exposed sensitive data. However, the absence of explicit security headers and incident response contact details are areas for improvement. The WHOIS data is unavailable due to a malformed query response, limiting domain registration insights, but the website's content and branding strongly support its legitimacy. Overall, the website is professional, trustworthy, and well-maintained, with minor areas for enhancement in privacy compliance and security transparency. The risk level is low, and the site effectively supports its community and business objectives.

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 holds a strong position in the open source database market, benefiting from decades of development and a vibrant global community. Its competitive advantages include reliability, extensibility, and a rich feature set that appeals to a broad range of users from individual developers to large enterprises. The business model is community-driven with no direct commercial sales, relying on community contributions, events, and ecosystem partnerships. The website reflects a mature digital presence with frequent updates, active event promotion, and extensive documentation. Growth indicators include recent major releases and a busy event calendar. The partnership ecosystem is implied through community events and mailing lists, although no explicit commercial partners are listed on the site.

Security posture

The website exhibits a mature security posture with mandatory HTTPS and secure form handling. The lack of visible security headers such as Content Security Policy (CSP) and HTTP Strict Transport Security (HSTS) suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. Privacy policies are comprehensive and GDPR compliant, but cookie consent mechanisms are absent, which may pose compliance risks. Incident response information is not explicitly provided, limiting transparency for security issues. Overall, the site is secure but would benefit from enhanced header policies and clearer incident response channels to strengthen trust and compliance.

Recommendations

  1. Implement and publish a cookie consent banner/mechanism to improve privacy compliance.
  2. Add security headers including Content Security Policy (CSP), HSTS, and X-Frame-Options to enhance protection against common web attacks.
  3. Publish a security.txt file and provide explicit incident response contact information to improve vulnerability disclosure and incident handling transparency.
  4. Regularly audit and update third-party scripts and tracking tools to minimize privacy risks and ensure compliance.
  5. Enhance WHOIS data availability or provide domain registration transparency to improve trust and legitimacy signals.

Technical notes

Notes

The website uses a modern and stable technology stack including Bootstrap 4.4.1 for responsive design, FontAwesome for icons, and Google Analytics and Tag Manager for analytics. The HTML is well-structured and semantic, supporting accessibility and SEO best practices. Performance is fast with minimal blocking scripts and asynchronous loading of analytics. No CMS is detected, suggesting a custom or static site approach. Hosting provider details are not disclosed. The site is mobile optimized and accessible, with clear navigation and consistent branding. Technical risks are low, but the absence of explicit security headers and cookie consent mechanisms are notable gaps. Opportunities exist to modernize security headers and enhance privacy controls to align with best practices.
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.
