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

Plyr is a small Australian technology company offering an open source, customizable HTML5 media player supporting video, audio, YouTube, and Vimeo integration. The website presents a professional and accessible interface targeting developers and content creators who need a simple yet flexible media player solution. The business model appears to be centered around open source distribution with community engagement via GitHub and partnerships such as with Mux for video hosting. Technically, the site uses modern web standards including HTML5, SVG icons, and JavaScript libraries like Plyr.js and HLS.js. It is hosted with Cloudflare DNS and registrar services, ensuring good performance and security. The site is mobile optimized and accessible, with proper meta tags and SEO considerations. From a security perspective, HTTPS is enforced, and domain registration is secure with clientTransferProhibited status. However, the site lacks explicit security headers, privacy and cookie policies, and vulnerability disclosure information, which are areas for improvement. No contact information or incident response channels are provided, limiting transparency. Overall, the site is trustworthy and professionally maintained but would benefit from enhanced privacy compliance and security documentation to improve user 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

9 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

Plyr occupies a niche in the technology sector as a provider of customizable media player software. Its competitive advantage lies in its open source nature, ease of integration with popular platforms like YouTube and Vimeo, and a strong GitHub presence with a large user base. The business targets developers and media content creators who require flexible media playback solutions. Revenue streams are likely indirect, possibly through partnerships (e.g., Mux) or donations. The company demonstrates growth potential through community engagement and strategic partnerships. The ecosystem includes GitHub for distribution and Mux for hosting, indicating a collaborative approach to service delivery.

Security posture

The security maturity of Plyr is moderate. The use of HTTPS and Cloudflare registrar with clientTransferProhibited status are positive indicators. However, the absence of DNSSEC, security headers, and published security policies reduces the overall security posture. There is no visible vulnerability disclosure or incident response information, which could hinder timely handling of security issues. Data protection practices are not explicitly documented, and no GDPR compliance statements are present. The site does not collect user data via forms, reducing exposure but also limiting user engagement options. Enhancing security documentation and implementing best practices would strengthen the security culture and compliance.

Recommendations

  1. Enable DNSSEC to improve DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies to comply with GDPR and other regulations.
  3. Add security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options to harden the site.
  4. Implement a vulnerability disclosure policy and provide incident response contact channels.
  5. Provide clear contact information to improve business credibility and user trust.

Technical notes

Notes

The website is built on a modern, lightweight tech stack leveraging HTML5, SVG, and JavaScript libraries including Plyr.js and HLS.js for media playback. Hosting and DNS are managed via Cloudflare, ensuring good performance and security. The site is mobile optimized and accessible, with proper use of meta tags and preloading fonts for performance. No CMS is detected, indicating a custom or static site approach. The absence of analytics or tracking scripts suggests a privacy-conscious design. Opportunities exist to improve technical security by adding security headers and enabling DNSSEC. Overall, the technical implementation is solid with room for modernization in security practices.
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.
