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

上海雍熙 is a Chinese internet company established in 2008 specializing in high-end website construction, mini-program APP development, software customization, and digital marketing services. The company serves over 120 listed companies including notable clients such as 宁德时代, ABB, and 西门子, positioning itself as a leading provider in the technology and energy sectors. The website demonstrates a professional and consistent brand image with comprehensive service offerings tailored to enterprise clients. Technically, the site uses modern JavaScript libraries like jQuery and Swiper.js, integrates Baidu analytics and marketing pixels, and is optimized for mobile devices with good SEO practices. Security posture is generally good with HTTPS enabled, but lacks visible security headers and formal privacy or cookie policies, indicating room for compliance improvement. The absence of WHOIS data for the domain raises concerns about domain registration legitimacy, though the active and professional website presence suggests a legitimate business. Overall, the site is well-designed and trustworthy but should address privacy compliance and domain registration transparency.

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. 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 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';…

  2. 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

  3. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 targets enterprise clients across multiple sectors including technology, energy, manufacturing, education, and healthcare. Its business model focuses on providing integrated digital solutions such as website customization, digital marketing, and app development. The presence of high-profile clients and over 3000+ case studies indicates strong market positioning and competitive advantage. The company leverages partnerships and subdomains like digital.yongsy.com to extend its digital marketing knowledge base. Revenue streams likely include project-based website development and ongoing marketing services. Growth indicators include recent case updates and active marketing campaigns. Strategic observations suggest the company could enhance trust by publishing privacy policies and clarifying domain ownership.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and no visible sensitive data exposure. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security is a notable gap. No vulnerability disclosures or incident response contacts are provided, which limits transparency and readiness perception. Compliance with GDPR or similar regulations is not evident due to missing privacy and cookie policies. The use of third-party analytics and marketing pixels introduces moderate tracking but no overt privacy controls. Overall, the security posture is adequate for business operations but requires enhancements in policy transparency, header implementation, and incident response readiness to meet higher compliance standards.

Recommendations

  1. Implement comprehensive privacy and cookie policies clearly accessible on the website to improve GDPR and privacy compliance.
  2. Add and configure essential security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen security posture.
  3. Verify and publish domain registration details to resolve WHOIS data inconsistencies and enhance domain legitimacy trust.
  4. Provide explicit incident response and vulnerability disclosure contact information to improve security transparency and readiness.
  5. Regularly audit third-party scripts and tracking pixels to ensure privacy compliance and minimize unnecessary user tracking.

Key observations

  1. Website is fully accessible with rich content and professional design.
  2. No privacy or cookie policies found, indicating compliance gaps.
  3. Contact information limited to phone and contact form; no verified company emails found.
  4. No security headers detected in HTML source; SSL is enabled.
  5. Multiple third-party scripts for analytics and marketing present.
  6. WHOIS data missing, which is unusual for an active commercial website.
  7. No evidence of adult or questionable content; content is business and technology focused.
Technical notes

Notes

The website uses a modern front-end stack including jQuery and Swiper.js for interactive elements, and integrates Baidu analytics and WowPop marketing pixels for data collection and advertising. The site is mobile-optimized with responsive design and good navigation clarity. Performance is moderate, likely influenced by multiple external scripts. No CMS or hosting provider information is explicitly detected. The HTML structure is valid and SEO meta tags are well implemented. However, the absence of security headers and privacy policies indicates technical debt in security and compliance areas. Opportunities exist to modernize security configurations and improve transparency. Technical risks include potential privacy compliance issues and domain registration ambiguity that could impact business reputation.
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.
