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

NetworkManager is an open source Linux network configuration tool suite widely recognized as the standard in its domain. The website serves primarily as a documentation and informational portal, targeting Linux users, system administrators, and IT professionals. It provides access to documentation and source code hosted on GitLab, emphasizing transparency and community collaboration. The business model is centered around open source software development and community support, positioning NetworkManager as a key technology project within the Linux ecosystem. Technically, the website is built using the Hugo static site generator, leveraging jQuery and tocbot for UI enhancements. The site is moderately optimized for performance and mobile devices, with good SEO practices evident through meta tags and structured navigation. However, accessibility features are basic, and no advanced frameworks or hosting details are disclosed. The absence of analytics or tracking scripts suggests a privacy-conscious approach, though no explicit privacy or cookie policies are provided. From a security perspective, the site lacks visible security headers and does not provide any security or incident response policies. HTTPS status and SSL configuration could not be confirmed from the provided data, but no WAF or blocking mechanisms were detected. The absence of contact information and policies reduces compliance posture and user trust. No vulnerabilities or exposed sensitive data were identified, but improvements in security best practices and transparency are recommended. Overall, the website is professional and functional but could benefit from enhanced privacy compliance, security policies, and contact transparency to improve trust and compliance. The risk level is moderate with no critical issues detected, but strategic improvements are advised to align with best practices and regulatory expectations.

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

5 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 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

NetworkManager holds a strong position as the standard Linux network configuration tool, serving a niche but critical market segment of Linux users and IT professionals. Its open source nature fosters community engagement and integration with popular desktop and server environments. The business model relies on open source development and community contributions rather than direct commercial revenue streams. The website supports this model by providing documentation and source code access without commercial distractions. The lack of explicit business contact details or corporate information suggests a community-driven project rather than a traditional commercial entity. Growth indicators include active code repositories and community engagement channels. Strategic partnerships or parent company affiliations are not evident, indicating independence. The website's clean, focused content and consistent branding support its credibility within the technology sector.

Security posture

The current security posture of the NetworkManager website is basic. The absence of security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces protection against common web attacks. No privacy or cookie policies are present, which impacts GDPR compliance and user trust. The lack of incident response or vulnerability disclosure information limits transparency and preparedness for security events. No forms or user input fields reduce attack surface but also limit user engagement options. The site does not appear to use tracking or analytics scripts, which is positive for privacy but may limit security monitoring capabilities. Overall, the site is low risk but would benefit from implementing standard security headers, publishing privacy and security policies, and providing clear contact channels for security incidents.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security to enhance protection.
  2. Publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance and user trust.
  3. Add clear contact information including security incident response contacts and vulnerability disclosure procedures.
  4. Enable HTTPS with strong SSL/TLS configuration and enforce HTTPS site-wide.
  5. Consider adding a security.txt file and vulnerability disclosure policy to foster responsible security reporting.

Technical notes

Notes

The website is built using the Hugo static site generator, which provides a lightweight and performant infrastructure. The use of jQuery 2.1.4 and tocbot indicates some legacy and modern JavaScript components for UI functionality. The site includes multiple CSS files for styling and demonstrates good SEO practices with meta tags and Open Graph properties. No CMS or dynamic backend is detected, reducing complexity and attack surface. Performance is moderate, with no explicit hosting provider identified. Mobile optimization is good, but accessibility features are basic and could be improved. No analytics or tracking scripts are present, indicating minimal data collection. The technical stack is appropriate for a documentation-focused site but could be modernized with updated JavaScript libraries and enhanced accessibility compliance.
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.
