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

ckplayer.com is a website offering an open-source JavaScript video player plugin supporting multiple video formats and streaming protocols. The product targets web developers and businesses needing reliable video playback solutions. The site is positioned as a niche player in the web video streaming technology sector, distributing software under the permissive MIT license. The website content is primarily technical and product-focused, with no commercial sales or direct contact information prominently displayed. Technically, the site uses a modern but basic tech stack including jQuery and Bootstrap, hosted on Alibaba Cloud. Performance and mobile optimization are adequate, though accessibility features are basic. Security posture is moderate with HTTPS assumed but lacking DNSSEC and security headers. Privacy and cookie policies are absent, indicating compliance gaps. Analytics usage includes Baidu and CNZZ tracking scripts, suggesting moderate user tracking without clear privacy disclosures. Overall, the site is functional and professional but would benefit from enhanced security and privacy practices to improve trust and compliance.

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 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 video player software. Its business model is based on free distribution under MIT license, targeting developers and enterprises requiring video streaming solutions. Market positioning is niche with a focus on technical users rather than mass consumers. The presence of community forums and technical support links indicates an engaged user base. The company appears small and specialized, with no parent or subsidiary companies identified. Partnerships with related product sites such as mayiui.com and bird.ckplayer.com suggest a small ecosystem of related offerings. The website's ICP license indicates compliance with Chinese regulatory requirements. Revenue streams are not explicit but may include support or advertising services. The business shows consistent branding and good content quality, supporting its credibility in the developer community.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is used, but DNSSEC is not enabled, and no security headers were detected in the provided data, which are areas for improvement. No exposed sensitive data or vulnerable libraries were found. The absence of privacy and cookie policies, as well as lack of incident response or vulnerability disclosure information, indicates compliance gaps and limited transparency in security practices. The use of third-party analytics scripts introduces moderate user tracking without clear privacy controls. Overall, the security posture is functional but could be significantly improved by implementing standard security headers, enabling DNSSEC, publishing privacy and cookie policies, and establishing formal incident response contacts.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  3. Publish comprehensive privacy and cookie policies to improve GDPR and general privacy compliance.
  4. Add a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.
  5. Provide clear contact information for security incidents and general inquiries to enhance trust and incident response readiness.

Technical notes

Notes

The website uses a straightforward technology stack with jQuery 3.5.0 and Bootstrap 4.3.1 for UI components, supported by custom CSS and JavaScript. The hosting is provided by Alibaba Cloud, a reputable provider. Performance is moderate with no explicit indicators of slow loading, and mobile optimization is good due to responsive design elements. SEO is basic with meta keywords and description tags present but no advanced structured data or Open Graph tags detected. Accessibility features are minimal but functional. The site lacks a CMS indication, suggesting a custom or static site architecture. Technical risks include missing DNSSEC and security headers, which could expose the site to certain attacks. Modernization opportunities include upgrading libraries and enhancing accessibility and SEO features.
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.
