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

React Suite is an established open source React UI component library founded in 2017, providing developers with a comprehensive set of frontend components including the Toaster notification system. The website serves as a documentation and resource hub, targeting frontend developers and teams building React applications. It is hosted on Alibaba Cloud and leverages modern web technologies such as React and Next.js, with integrations for Storybook and code sandbox for interactive examples. The site demonstrates good technical maturity with fast performance, mobile optimization, and accessibility considerations. Security posture is adequate with HTTPS enabled and no exposed sensitive data, but lacks published security policies or incident response information. Privacy compliance is weak due to absence of privacy and cookie policies or consent mechanisms. Overall, the domain registration and WHOIS data are consistent and legitimate, supporting the trustworthiness of the site.

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 Suite operates in the technology sector as a provider of React UI components, positioning itself as a popular and reliable framework for frontend development. Its business model is primarily open source with community and enterprise usage. The website includes trust signals such as GitHub repository links and Storybook integration, enhancing credibility. The target audience is developers and software teams seeking UI solutions. The company appears medium-sized with a focused product offering. There is no evidence of parent or subsidiary companies. The site content is well structured and professionally presented, supporting a positive market presence and growth potential.

Security posture

The website employs HTTPS and uses modern web standards, which is a strong baseline for security. However, it lacks explicit security headers and published security policies, which are important for transparency and incident management. No vulnerability disclosure or security.txt files are present, limiting the ability for external security researchers to report issues. The absence of privacy and cookie policies also indicates compliance gaps with GDPR and related regulations. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The security score is moderate, with recommendations to enhance headers, policies, and disclosure mechanisms to improve overall security maturity.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with consent mechanisms to improve GDPR compliance.
  2. Implement and publish a security policy and incident response plan accessible on the website.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Create a vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
  5. Enable DNSSEC for the domain to enhance DNS security and trust.

The site is performant with deferred and async script loading, and includes accessibility features. The technical implementation is modern and well executed, with opportunities to improve security headers and privacy compliance. No CMS was detected, indicating a custom or framework-based site.

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.
