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

The website '美术加AI' offers an AI-powered learning tool designed primarily for art students and enthusiasts in China. It provides advanced AI drawing assistance, personalized learning plans, and real-time feedback to help users improve their artistic skills across various mediums such as sketching, watercolor, and oil painting. The platform supports interactive features including image uploads and generation of art based on prompts, with purchasable generation credits. Technically, the site is built using modern web technologies including React, Next.js, and Ant Design, delivering a responsive and user-friendly experience optimized for mobile devices. However, the site lacks visible privacy and cookie policies, contact information, and security headers, which are important for compliance and trust. The WHOIS data for the domain is unavailable, raising concerns about domain legitimacy and ownership transparency. Overall, the site is functional and content-rich but requires improvements in security posture, privacy compliance, and business transparency to enhance trust and regulatory adherence.

NIS2 Art. 21(2)

  1. (a) Risk analysis and security policies: Not visible from outside

  3. (c) Business continuity, backups and crisis management: Not visible from outside
  4. (d) Supply chain security: Not visible from outside

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.

Business context

Business profile

美术加AI positions itself as a specialized AI tool for the art education sector, targeting students and hobbyists seeking to enhance their drawing and painting skills through AI assistance. Its business model revolves around offering AI-generated art services with a credit-based purchase system. The platform leverages partnerships with Chinese enterprise communication tools (e.g., work.weixin.qq.com) for collaboration and procurement inquiries. The absence of clear company registration or contact details limits the ability to fully assess business credibility. The use of Baidu Analytics indicates a focus on user behavior tracking within the Chinese market. The platform's competitive advantage lies in its tailored AI models for different art subjects and styles, catering specifically to the Chinese art student demographic.

Security posture

The website employs HTTPS for secure communication, but lacks visible security headers such as Content Security Policy (CSP), HSTS, or X-Frame-Options, which are critical for mitigating common web vulnerabilities. No sensitive data exposure or vulnerable libraries were detected in the HTML content. The absence of privacy and cookie policies, as well as incident response contacts, indicates gaps in compliance with data protection regulations such as GDPR. The missing WHOIS registration data for the domain is a significant concern, as it impairs trust and raises questions about domain ownership legitimacy. Overall, the security posture is moderate but requires enhancements in policy transparency, header implementation, and domain registration verification.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Add security headers including CSP, HSTS, and X-Frame-Options to strengthen web security.
  3. Provide clear contact information and incident response channels for security and abuse reporting.
  4. Verify and maintain accurate WHOIS domain registration data to enhance legitimacy and trustworthiness.
  5. Conduct regular security audits and update dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is developed using a modern JavaScript stack with React and Next.js frameworks, supported by Ant Design UI components. It delivers a mobile-optimized experience with responsive design and preloading of critical CSS and scripts. The site integrates Baidu Analytics for user tracking and uses external static resource hosting on res.meishujai.com. Performance is moderate with deferred script loading and prefetching strategies. However, there is no detected CMS or hosting provider information. Accessibility features are basic, and SEO optimization is minimal but present through meta tags. The lack of security headers and privacy compliance pages indicates technical debt in security and regulatory adherence.
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.
