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

The website www.yasuotu.com is a Chinese online platform specializing in image compression and AI-powered image processing tools. It offers a wide range of services including batch image compression, DPI modification, PDF conversions, certificate photo creation, and AI-based background removal and photo enhancement. The platform targets general users and professionals seeking efficient online image editing solutions, positioning itself as a comprehensive and user-friendly service in the Chinese market. The business operates under 山东找图网络科技有限公司 and has been active since at least 2016, supported by an ICP license indicating regulatory compliance in China. Technically, the website employs a mature technology stack including jQuery, Bootstrap, and layui frameworks, with additional libraries for UI components and file uploading. The site is mobile-optimized and provides a good user experience with clear navigation and professional design. Performance is moderate, and SEO practices are adequately implemented. Security-wise, HTTPS is enforced and forms include CSRF tokens, but the absence of advanced security headers and a cookie consent mechanism indicates room for improvement in security posture and privacy compliance. The WHOIS data is notably absent, with the domain showing no registration information in the raw WHOIS output. This inconsistency raises concerns about domain legitimacy and transparency, although the presence of an ICP license and active customer support channels mitigate some risk. No signs of WAF or content blocking were detected, allowing full content analysis. The site does not contain adult or questionable content and is safe for general audiences. Overall, www.yasuotu.com is a functional and professional online image processing service with solid business credibility but requires enhancements in security headers, privacy compliance, and domain registration transparency to improve trust and compliance with international standards.

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 company behind www.yasuotu.com, 山东找图网络科技有限公司, operates a medium-sized technology business focused on online image processing tools. Their business model includes free online services with options for paid membership upgrades, targeting a broad user base in China. The platform's extensive feature set and integration of AI technologies provide competitive advantages in the digital image editing market. The company maintains a network of related external links to design resources and templates, indicating an ecosystem approach. Revenue streams likely include premium subscriptions and possibly advertising or affiliate partnerships. The presence of a help center and customer service via QQ and phone supports customer engagement and retention. However, the lack of visible certifications or security policies suggests opportunities to strengthen market trust and compliance. The company appears stable with a consistent brand presence since 2016.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is properly implemented, and forms include CSRF tokens, which are positive indicators. However, the absence of key security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security reduces defense-in-depth. No security.txt or vulnerability disclosure policy is published, limiting transparency and incident response readiness. Privacy compliance is partial, with no cookie consent mechanism detected, which may expose the company to regulatory risks under GDPR or similar frameworks. No exposed sensitive data or vulnerable libraries were identified in the HTML content. Overall, the security posture is functional but could be significantly improved by adopting modern security best practices, publishing clear policies, and enhancing user privacy protections.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish a security policy and vulnerability disclosure guidelines (security.txt) to improve transparency and incident response capabilities.
  3. Add a cookie consent banner and privacy controls to comply with GDPR and other privacy regulations.
  4. Regularly update third-party libraries and frameworks to mitigate risks from known vulnerabilities.
  5. Enhance accessibility features to improve usability for all users and comply with accessibility standards.

Technical notes

Notes

The website uses a combination of mature front-end technologies such as jQuery 1.9.1, Bootstrap 3.3.4, and layui UI framework, supplemented by libraries like lightbox2 and webuploader for image handling. The site is mobile-optimized with responsive design elements and includes SEO-friendly meta tags. Performance is moderate, with some room for optimization in loading speed and accessibility. The absence of a detected CMS suggests a custom or proprietary platform. Hosting provider details are not disclosed. The technical implementation supports a robust user experience but would benefit from modernization of libraries and enhanced security configurations to reduce technical debt and improve resilience.
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.
