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

The nginx.org website represents the official online presence of the nginx web server technology, which is a widely used HTTP web server, reverse proxy, load balancer, and proxy server solution. The product was originally developed by Igor Sysoev and is now supported commercially by F5, Inc., a large enterprise technology company. The website provides comprehensive product information, documentation, community resources, and links to official code repositories, targeting developers, IT professionals, and enterprises seeking robust web server and proxy solutions. The business model combines open source distribution with enterprise support and training services. From a technical perspective, the website is well-structured with modern HTML and CSS, good mobile optimization, and clear navigation. It links to multiple official projects and GitHub repositories, indicating a mature and active development ecosystem. No content blocking or WAF challenges were detected, and the domain registration data is consistent with the business claims, supporting a high level of trustworthiness. Security posture analysis reveals that while the website does not expose sensitive data or vulnerable libraries, it lacks explicit security headers, published security policies, and incident response contact information. Additionally, privacy and cookie policies are absent, which may impact compliance with GDPR and other regulations. The domain is secured with HTTPS (implied by the official domain and modern standards), but DNSSEC is not enabled, which could be improved. Overall, the website is professional, credible, and technically sound but would benefit from enhanced privacy compliance and security transparency to further strengthen trust and regulatory adherence.

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

7 findings rated critical or high. Fix these first.

  1. 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';…

  2. 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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

nginx.org is positioned as a leading technology provider in the web server and proxy market, leveraging a hybrid open source and enterprise support business model. The company benefits from strong brand recognition and a large user base. Revenue streams likely include enterprise subscriptions, support contracts, and training services. The target customers are developers, IT operations teams, and large enterprises requiring scalable and reliable web infrastructure. The website ecosystem includes community forums, documentation, and multiple related projects, indicating a robust partnership and developer engagement strategy. The parent company, F5, Inc., is a well-established enterprise technology firm, enhancing market credibility and resource availability. Growth indicators include regular product updates and active community involvement.

Security posture

The current security maturity level of the nginx.org website is moderate. The site does not reveal any critical vulnerabilities or exposed sensitive information. However, the absence of published security policies, incident response contacts, and security headers represents a gap in security transparency and best practices. GDPR and privacy compliance are weak due to missing privacy and cookie policies. Incident response readiness cannot be assessed due to lack of contact channels. The security culture appears focused on product robustness rather than website security disclosures. To improve, the organization should publish clear security and privacy policies, enable DNSSEC, and implement security headers to protect users and enhance trust.

Recommendations

  1. Publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Implement and publicly disclose a security policy and incident response contact information to enhance transparency and readiness.
  3. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  4. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve client-side security.
  5. Provide clear contact information including emails or phone numbers for support and security inquiries to improve business credibility.

Technical notes

Notes

The nginx.org website uses a clean and modern technical infrastructure with HTML5 and CSS for layout and styling. The presence of njs (NGINX JavaScript) indicates use of ECMAScript-compatible scripting to extend functionality. The site links to multiple GitHub repositories, showing active open source development. Hosting and domain registration are managed by reputable providers consistent with the parent company F5, Inc. Performance is likely fast given the minimalistic design and efficient content delivery. Mobile optimization is good, with responsive design elements. No CMS or third-party analytics scripts were detected in the provided HTML, indicating a lightweight and privacy-conscious implementation. Opportunities exist to modernize security configurations and add privacy compliance 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.
