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

6 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

Tuchong.com holds a strong market position as a large-scale photography community and stock photo provider in China. Its business model leverages user-generated content monetized through multiple sales channels and contributor incentives. The platform's partnerships with brands and events enhance its ecosystem and user engagement. The company benefits from regulatory compliance and transparent policies, supporting sustainable growth. The target audience includes photography professionals and enthusiasts, with a focus on originality and community interaction. The platform's extensive content and active events indicate a vibrant user base and competitive advantage in the Chinese digital media space.

Security posture

The website maintains a good security baseline with HTTPS enforced and domain transfer restrictions. Use of RSA encryption scripts suggests attention to secure data handling. However, the absence of DNSSEC and security headers like CSP or HSTS indicates room for enhancement. No vulnerabilities or exposed sensitive data were detected in the analysis. Incident response contact is provided via a feedback email, but no formal security policy or vulnerability disclosure page was found. Privacy compliance is basic, with a privacy policy present but no explicit cookie consent mechanism. Overall, the security posture is moderate to good but could be improved to meet higher standards and compliance requirements.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve DNS security.
  2. Implement security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to enhance browser security.
  3. Publish a security.txt file or dedicated vulnerability disclosure policy to facilitate responsible reporting of security issues.
  4. Add a cookie consent banner or mechanism to comply with privacy regulations and improve user transparency.
  5. Consider providing more explicit contact information including phone numbers and physical addresses to enhance business credibility.

Technical notes

Notes

The website uses a modern JavaScript-based front-end with libraries such as Swiper.js for UI components and custom analytics SDKs for event tracking. RSA encryption is included, indicating secure client-side operations. DNS prefetching is used to optimize resource loading. Hosting is via Volcengine DNS servers, a reputable cloud provider. Performance is moderate with asynchronous script loading and caching controls. SEO is supported by meta tags and structured data, though no JSON-LD was detected. Accessibility is basic, with room for improvement in ARIA roles and semantic markup. The site is mobile-optimized with responsive design elements. Overall, the technical infrastructure is solid but could benefit from enhanced accessibility and security features.
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.
