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

Dropzone.js is an open source JavaScript library that facilitates drag and drop file uploads with image previews. It is positioned as a popular and robust tool for developers seeking easy-to-integrate file upload solutions. The website serves as a hub for documentation, source code access via GitHub, and community support through Stack Overflow and GitHub Discussions. Technically, the site is built using the Svelte framework and includes modern JavaScript practices, delivering a fast and mobile-optimized experience. Security-wise, the site uses HTTPS but lacks important security headers and formal privacy or cookie policies, which are areas for improvement. No contact information or incident response details are provided, limiting direct communication channels. Overall, the site is trustworthy and professional but could enhance compliance and security posture.

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. 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

The business model revolves around open source software distribution targeting developers and website owners. The project maintains a strong community presence on GitHub and social media, facilitating support and collaboration. The lack of formal business contact details and policies suggests a community-driven project rather than a commercial enterprise. The site’s content and features indicate a focus on ease of use, customization, and broad browser compatibility, which are competitive advantages. Growth is supported by active documentation and community engagement. No direct partnerships or subsidiaries are identified.

Security posture

The website demonstrates a basic security posture with HTTPS enabled, ensuring encrypted communications. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No vulnerability disclosure or incident response information is available, which could hinder timely security issue reporting and resolution. The minimal tracking via plausible.io respects user privacy but the lack of privacy and cookie policies indicates compliance gaps, especially regarding GDPR. No exposed sensitive data or vulnerable libraries were detected in the HTML content.

Recommendations

  1. Implement comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Provide clear contact information for security incidents and general inquiries to improve communication and incident response.
  4. Consider publishing a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Enhance accessibility features to improve inclusivity and compliance with accessibility standards.

Technical notes

Notes

The website uses a modern tech stack centered on the Svelte framework and the Dropzone.js library. It leverages module preloading and external CSS/JS resources for performance optimization. The site is mobile optimized and provides a clean, professional design with clear navigation. No CMS or hosting provider details are evident from the HTML. Analytics are implemented via plausible.io, a privacy-focused service. The site lacks some security best practices such as security headers and formal policies. Overall, the technical implementation is solid with room for security and compliance enhancements.
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.
