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

jPlayer.org is the official website for jPlayer, a free and open source HTML5 audio and video media player plugin for jQuery and Zepto. Operated by Happyworm Ltd, the site serves a developer audience seeking cross-platform media playback solutions. The project is well-established since 2010 with an active community and GitHub presence, positioning it as a reputable player in the web media technology space. Technically, the site uses a modern JavaScript stack with jQuery, Zepto, and HTML5, supported by Cloudflare DNS and external analytics and social media integrations. However, some technical debt is evident in the lack of modern security headers and partial use of HTTP resources. Security posture is moderate with no critical vulnerabilities detected but lacking in privacy and cookie policy compliance. The domain registration is consistent and legitimate, with no privacy protection masking ownership, supporting trustworthiness. Overall, the site is professional and functional but would benefit from improved privacy compliance and security hardening.

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. 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 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';…

  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

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 operates in the technology sector focusing on open source media player software. Its competitive advantage lies in its free MIT license, extensive codec and platform support, and an active developer community. Revenue streams likely include donations, commercial services via Happyworm Ltd, and possibly consulting or custom development. The target customers are web developers and media content creators requiring customizable media playback solutions. Growth indicators include ongoing GitHub activity and community engagement. Partnerships with related sites like jplayer.it and hyperaud.io enhance ecosystem reach. The business model balances open source community engagement with commercial service offerings.

Security posture

The website demonstrates a moderate security maturity level. While HTTPS is implied, no explicit security headers such as CSP or HSTS are detected, and DNSSEC is not enabled. There is no published privacy or cookie policy, nor a vulnerability disclosure or incident response contact, indicating compliance gaps with GDPR and best practices. External scripts include Google Analytics and Twitter widgets, increasing tracking footprint without clear consent mechanisms. No exposed sensitive data or known vulnerabilities are visible in the HTML content. Incident response readiness and security culture indicators are minimal. Overall, the security posture is functional but requires enhancements to meet modern compliance and protection standards.

Recommendations

  1. Publish comprehensive privacy and cookie policies with explicit user consent mechanisms to improve GDPR compliance.
  2. Implement security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to harden the site against common web attacks.
  3. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  4. Ensure all external resources load over HTTPS exclusively to avoid mixed content vulnerabilities.
  5. Establish and publish a vulnerability disclosure policy and incident response contact information to improve security transparency and readiness.

Technical notes

Notes

The website uses a mature JavaScript technology stack centered on jQuery and Zepto for media playback, with HTML5 and CSS3 for styling and layout. Hosting is supported by Cloudflare DNS, enhancing availability and performance. The site includes multiple external scripts for analytics, social media integration, and donation facilitation. Performance is moderate with room for optimization, especially by minifying and combining scripts as noted in the source comments. Mobile optimization is good, supporting a range of platforms including iOS and Android. Accessibility features are basic, and SEO optimization is minimal but present through meta tags. Technical debt is evident in legacy script usage (e.g., html5shiv) and partial HTTP resource loading. Modernization opportunities include adopting a CMS or static site generator for easier content management and improving security configurations.
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.
