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

The website www.jj20.com is a Chinese language wallpaper portal offering a wide range of high-definition desktop and mobile wallpapers including categories such as landscapes, flowers, celebrities, and cartoons. It targets general users seeking free wallpaper content and positions itself as a niche media content provider in the wallpaper segment. The site features a basic search form and extensive categorized content but lacks visible business contact information or formal policies. Technically, the site uses standard HTML, CSS, and JavaScript with Baidu Analytics for user tracking. The site appears moderately optimized for mobile and SEO but lacks advanced accessibility features and security headers. Security posture is weak due to missing HTTPS confirmation and absence of security best practices. The WHOIS data is unavailable, which raises concerns about domain registration legitimacy but does not directly impact the content quality. Overall, the site is functional but requires improvements in security, privacy compliance, and business transparency to enhance 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

10 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 as a content portal providing free wallpaper images primarily to Chinese-speaking users. Its business model likely relies on advertising and affiliate partnerships, as indicated by numerous external links to related image and design resource sites. The site lacks direct monetization or e-commerce features. The absence of formal privacy and cookie policies and contact details suggests a small-scale operation with limited formal business infrastructure. The extensive partner ecosystem indicates a strategy to leverage related content providers for traffic and resource sharing. Growth potential depends on improving user trust, security, and compliance with data protection regulations.

Security posture

The website currently exhibits a low security maturity level. There is no evidence of HTTPS enforcement or security headers, which exposes users to potential interception or manipulation risks. The site uses JavaScript libraries without indication of vulnerability management. No privacy or incident response policies are present, and no contact channels for security issues are provided. The lack of WHOIS data further complicates trust assessment. These gaps increase the risk of data leakage, user tracking without consent, and potential exploitation. The site should prioritize implementing HTTPS, security headers, privacy policies, and incident response mechanisms to improve its security posture.

Recommendations

  1. Implement HTTPS across the entire website to secure user data and improve trust.
  2. Publish comprehensive privacy and cookie policies to comply with data protection regulations.
  3. Add clear contact information including business email and phone numbers for user support and incident reporting.
  4. Deploy security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  5. Establish an incident response plan and provide dedicated security contact channels to handle vulnerabilities and abuse reports.

Technical notes

Notes

The website is built using standard web technologies including HTML, CSS, and JavaScript, with Baidu Analytics integrated for user tracking. The site uses a gb2312 charset indicating a focus on Chinese users. The presence of multiple external JavaScript and CSS resources suggests a modular front-end design. The site lacks modern frameworks or CMS indications, implying a custom or legacy platform. Performance is moderate with basic mobile optimization and SEO meta tags present. However, the absence of HTTPS and security headers indicates technical debt in security implementation. The search form uses POST method but lacks visible CSRF tokens or advanced input validation. Overall, the technical infrastructure is functional but requires modernization and security enhancements.
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.
