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

优绿软 is a Chinese-language website specializing in providing free downloads of mobile software and Android applications, including games and utility apps. The site targets Chinese-speaking Android users seeking categorized and easy access to popular and trending apps. The business operates as a niche app download portal with a focus on user convenience and software variety. Technically, the website uses basic HTML, CSS, and JavaScript with legacy charset encoding (gb2312), indicating a traditional or regional web design approach. The site is accessible without any WAF or security challenges, but lacks modern security features such as HTTPS and security headers. There is no visible privacy or cookie policy, and no contact information is provided, which impacts trust and compliance. The domain WHOIS data is unavailable or unregistered, which raises concerns about legitimacy despite the presence of official Chinese ICP and public security registrations. Overall, the site is functional but requires significant improvements in security, privacy compliance, and transparency to enhance trustworthiness and user confidence.

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

7 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. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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"

  4. 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 website positions itself as a free Android app and game download portal catering primarily to Chinese users. It leverages partnerships with related mobile software and gaming sites, as evidenced by friendly links. The business model appears to be based on providing categorized app downloads, possibly monetized through advertising or affiliate links, although no explicit advertising networks were detected. The site’s market presence is modest, with a small-scale operation indicated by limited business information and lack of contact details. Growth potential exists in expanding content quality, improving user experience, and enhancing security and compliance to meet modern standards. The partnership ecosystem is limited but relevant to the mobile app niche. Strategic focus on trust-building and compliance could improve market position.

Security posture

The website currently exhibits a low security maturity level. It lacks HTTPS, exposing users to potential data interception risks. No security headers are implemented, increasing vulnerability to common web attacks such as clickjacking or MIME sniffing. There is no published privacy or cookie policy, indicating poor compliance with data protection regulations like GDPR. No incident response or security contact information is available, limiting the ability to report or respond to security incidents. The absence of WHOIS data further reduces trust and raises legitimacy concerns. To improve security posture, the site should implement HTTPS, add security headers, publish comprehensive privacy and cookie policies, and provide clear contact channels for security incidents.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate to secure user connections.
  2. Publish clear and comprehensive privacy and cookie policies to enhance compliance and transparency.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  4. Provide explicit contact information including security incident response contacts to improve trust and incident handling.
  5. Conduct a thorough security audit and vulnerability assessment to identify and remediate potential risks.

Technical notes

Notes

The website uses a simple technology stack consisting of HTML, CSS, and JavaScript without modern frameworks or CMS detected. The charset is gb2312, which is outdated and may limit accessibility and SEO performance. The site is moderately optimized for mobile but lacks advanced accessibility features. SEO optimization is basic with meta keywords and description present but no structured data or Open Graph tags detected. Performance is moderate with no explicit indicators of optimization or CDN usage. The site does not use analytics or tracking services, limiting data-driven insights. Technical debt is evident in legacy encoding and lack of modern security practices. Modernization opportunities include adopting UTF-8 encoding, implementing HTTPS, enhancing SEO with structured data, and improving mobile responsiveness and accessibility.
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.
