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

The website www.deelcn.com, branded as 中当网, operates as a Chinese software and game download platform offering a wide range of free PC and mobile applications, including games and technical articles. It targets computer and mobile enthusiasts seeking green, safe, and cracked software with a clean user experience. The site is moderately sized with a consistent brand presence and good content quality. Technically, it employs standard web technologies such as HTML5, CSS, JavaScript, jQuery, and uses Cloudflare CDN and analytics services like 51.la and Cloudflare Insights. The site is mobile-optimized and has good SEO and navigation structure. Security-wise, it enforces HTTPS and includes several security headers, but lacks visible privacy and cookie consent mechanisms and does not provide explicit security incident response or vulnerability disclosure information. WHOIS data is unavailable, which raises some legitimacy concerns but the active and professional nature of the site mitigates this somewhat. Overall, the site scores moderately well in content quality, technical implementation, and security posture but has room for improvement in privacy compliance and business credibility.

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 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.

Dark web exposure

Add-on

Leaked records that mention deelcn.com, from OffSeq Breach.

No leaked records found

Breach holds no records for deelcn.com right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The platform positions itself as a free software and game download hub in the Chinese market, focusing on green and cracked software, which appeals to a niche audience of enthusiasts. Its business model is likely ad-supported, with no direct monetization visible. The site maintains partnerships with related domains like qadmin.net, indicating some ecosystem integration. The absence of detailed company information and WHOIS data limits transparency. The site’s extensive categorized content and regular updates suggest active management and a stable user base. Growth potential exists if privacy compliance and trust signals are enhanced.

Security posture

The website demonstrates a good baseline security posture with HTTPS enforcement and multiple security headers. It uses Cloudflare CDN, which adds protection and performance benefits. However, the lack of a cookie consent mechanism and privacy policy details indicates compliance gaps, especially regarding GDPR or similar regulations. No explicit incident response or vulnerability disclosure channels are provided, which could hinder timely security issue reporting and resolution. No known vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, security practices are adequate but could be improved with formal policies and user privacy controls.

Recommendations

  1. Implement a clear and accessible cookie consent banner to comply with privacy regulations.
  2. Publish a comprehensive privacy policy detailing data collection, usage, and user rights.
  3. Add explicit security incident response contact information and consider a vulnerability disclosure policy or security.txt file.
  4. Enhance business credibility by providing verified contact emails and phone numbers.
  5. Improve accessibility features to broaden user inclusivity and compliance.

Technical notes

Notes

The website uses a traditional web stack with HTML5, CSS, and JavaScript libraries including jQuery and SuperSlide for UI effects. It leverages Cloudflare CDN for hosting and performance optimization and integrates 51.la analytics for user tracking. The site redirects mobile users to a dedicated mobile version, indicating good mobile support. The CMS appears to be Destoon or a similar Chinese CMS based on URL patterns and content structure. Performance is moderate with room for optimization. SEO is well addressed with meta tags and structured navigation. No modern JavaScript frameworks or advanced backend technologies are evident from the HTML source. Technical risks are low but modernization could improve scalability and maintainability.
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.
