React Router is a widely adopted open-source routing library for React applications, officially backed by Shopify, Inc. The website serves as the official documentation portal, providing comprehensive guides, upgrade paths, and community support channels. It targets React developers seeking robust routing solutions compatible with modern React versions including React 18 and 19. The business model centers on open-source community engagement supported by Shopify's enterprise resources, positioning React Router as a leading technology in the React ecosystem. Technically, the website employs modern web technologies including React, Tailwind CSS, and Cloudflare DNS services, ensuring fast performance, mobile optimization, and good accessibility. The site is well-structured with clear navigation and professional design, reflecting a mature digital presence. However, it lacks explicit privacy and cookie policies, which are important for compliance and user trust. From a security perspective, the domain is secured with HTTPS and domain status locks, but the absence of DNSSEC and security headers suggests room for improvement. No vulnerabilities or exposed sensitive data were detected. The site does not currently provide a vulnerability disclosure policy or security contact information, which could enhance its security posture. Overall, React Router's website is a high-quality, trustworthy resource for developers, with strong business credibility and technical implementation. Strategic improvements in privacy compliance and security best practices would further strengthen its position and user trust.

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

8 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 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

    • 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

React Router holds a strong market position as a leading React routing library with over 2.7 billion npm downloads and a large contributor base on GitHub. Its open-source model, supported by Shopify, enables rapid innovation and community engagement. The target audience is primarily software developers and engineers working with React. The project benefits from Shopify's enterprise backing, enhancing credibility and resources. Partnerships with platforms like GitHub and Discord facilitate community support and collaboration. The business model leverages open-source adoption and developer goodwill rather than direct monetization. Growth indicators include active contributor count and frequent updates bridging React versions. Strategic observations highlight the importance of expanding compliance documentation and security transparency to maintain leadership in a competitive ecosystem.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and domain registration includes protective statuses preventing unauthorized transfers or deletions. However, the lack of DNSSEC and security headers such as Content-Security-Policy or Strict-Transport-Security indicates potential gaps. No explicit incident response or security contact information is provided, limiting transparency for vulnerability reporting. There are no visible vulnerabilities or exposed sensitive data in the HTML content. Compliance with GDPR and other privacy regulations is not clearly documented, which could pose risks in regulated markets. Overall, the security culture appears functional but could benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies to enhance GDPR and privacy compliance.
  3. Implement and deploy security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide explicit security incident response contact information and consider publishing a security.txt file.
  5. Regularly audit and update dependencies to avoid vulnerable libraries and maintain secure codebase.

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.
