Risk levelMedium

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

MESNAC CO., LTD. is a large, established international high-tech enterprise group founded in 2000 and developed by Qingdao University of Science and Technology. The company specializes in smart rubber machinery, new materials, and emerging business sectors such as industrial IoT and environmental protection, serving a global industrial audience. Their market position is strong within the rubber machinery smart manufacturing industry, supported by multiple global R&D centers and a broad patent portfolio. Technically, the website employs a modern JavaScript and CSS stack including Bootstrap, jQuery, and various UI libraries, delivering a moderate performance and good mobile optimization. Security posture is adequate with HTTPS usage but lacks explicit security headers and formal security policies. Privacy compliance is weak due to missing privacy and cookie policies. Overall, the website is professional and trustworthy but could improve transparency and security practices.

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. 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';…

  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

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

MESNAC operates primarily in manufacturing and technology sectors with a B2B business model targeting industrial clients. Their competitive advantages include a strong R&D foundation, leadership in industry standards, and a diversified portfolio covering smart machinery and new materials. The company maintains a global footprint with customers in over 60 countries and multiple service centers. Revenue streams likely derive from machinery sales, technology solutions, and emerging business services. The company ecosystem includes subsidiaries and a parent university affiliation. Strategic observations highlight a focus on innovation, digitalization, and sustainability within the rubber industry.

Security posture

The current security maturity level is moderate. The website uses HTTPS but lacks visible security headers such as CSP, HSTS, or X-Frame-Options. No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of privacy and cookie policies indicates compliance gaps, particularly regarding GDPR. Incident response and vulnerability disclosure mechanisms are not publicly documented, which may impact readiness. The security culture appears basic with room for improvement in transparency and best practices.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance.
  2. Add security headers (CSP, HSTS, X-Frame-Options) to enhance protection against common web attacks.
  3. Publish a vulnerability disclosure policy and incident response contact information to improve security transparency.
  4. Enhance website accessibility features to meet modern standards.
  5. Improve SEO metadata and structured data to boost search engine visibility and user experience.

Technical notes

Notes

The website is built on a solid technical foundation using Bootstrap for responsive design and jQuery for DOM manipulation. Additional libraries like Slick Slider, Swiper, and Fluidplayer enhance UI and media capabilities. The site loads a variety of JavaScript plugins for animations and lazy loading, contributing to moderate performance. No CMS was detected, suggesting a custom or proprietary platform. Hosting provider details are not available. Technical debt appears low, but improvements in accessibility and SEO are recommended to modernize the site further and reduce potential risks.
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.
