59/100

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

上海君君信息技术有限公司 operates the website www.ijunjun.com, providing comprehensive digital marketing services including SEO optimization, SEM advertising, brand reputation management, new media marketing, website and mini-program development, and public opinion management. The company targets enterprises seeking to enhance their online presence and marketing effectiveness, positioning itself as a professional and experienced marketing service provider in Shanghai with over 11 years of industry experience. The website is well-structured, mobile-optimized, and integrates Baidu analytics and marketing tools, reflecting a moderate level of digital maturity. However, the absence of WHOIS registration data and lack of explicit privacy and cookie policies indicate gaps in transparency and compliance. Security posture is moderate with HTTPS usage but missing security headers and incident response information. Overall, the website presents a professional image but would benefit from enhanced privacy compliance and security best practices to improve trust and regulatory adherence.

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

4 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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

    • 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

  • Security headers: did not complete in this scan.
  • 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 operates in the technology and media sectors, focusing on integrated marketing solutions for businesses. Its business model revolves around service provision and project-based engagements, leveraging SEO, SEM, and new media platforms to drive client growth. The firm has a solid client base with over 100 customers and a high KPI achievement rate, indicating effective service delivery. Partnerships with multiple media and marketing channels enhance its market reach. The company’s strategic focus on multi-platform marketing and brand reputation aligns with current digital marketing trends in China. However, the lack of publicly available WHOIS data and privacy documentation may affect client trust and regulatory compliance.

Security posture

The website employs HTTPS, which is fundamental for secure communications. It uses reputable JavaScript libraries and Baidu analytics for tracking. However, the absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces protection against common web attacks. No visible vulnerabilities or exposed sensitive data were detected in the HTML content. The site lacks documented incident response contacts and security policies, which are important for handling security events. Privacy and cookie policies are missing, indicating potential compliance gaps with GDPR or similar regulations. Overall, the security posture is moderate but requires improvements in headers, policies, and incident readiness.

Recommendations

  1. Implement comprehensive privacy and cookie policies to enhance compliance and user trust.
  2. Add security headers including CSP, HSTS, and X-Frame-Options to strengthen web security.
  3. Publish incident response and security contact information to improve transparency and readiness.
  4. Update JavaScript libraries to latest versions to mitigate potential vulnerabilities.
  5. Enhance accessibility features to improve user experience for all users.

Technical notes

Notes

The website uses a combination of jQuery 1.8, Swiper 5.4, and WOW.js for animations and interactivity, which are somewhat dated but functional. Baidu analytics and site verification scripts are integrated for tracking and SEO purposes. The site is mobile optimized with responsive design and uses modern CSS animations. No CMS is explicitly detected, suggesting a custom or static site build. Performance is moderate with autoplay sliders and animations that may impact load times. The site lacks advanced accessibility features but maintains clear navigation and structure. Hosting provider details are not discernible from the HTML content. Overall, the technical infrastructure is adequate but could benefit from modernization and performance optimization.
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.
