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

常州市腾龙塑料机械有限公司 is a medium-sized manufacturing company specializing in plastic machinery such as coating and laminating machines, extrusion composite film machines, and related industrial equipment. The company has a significant market presence in China, with a product portfolio targeting industrial manufacturers and packaging companies. The website reflects a professional business with clear contact information and product offerings, although the domain WHOIS data is missing, raising some concerns about domain registration legitimacy. Technically, the website uses legacy JavaScript libraries like jQuery 1.8.3 alongside modern UI components such as Swiper and Slick carousels. The site is moderately optimized for performance and mobile use but lacks advanced SEO and accessibility features. Security posture is moderate with no HTTPS status visible and no security headers detected, and privacy compliance is minimal due to absence of privacy and cookie policies. Security-wise, the site does not expose sensitive data but would benefit from implementing HTTPS, security headers, and formal privacy policies. The lack of WHOIS data and domain registration information is a notable risk factor. Overall, the website is functional and business-focused but requires improvements in security and compliance to enhance trust and resilience.

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

5 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. 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

  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

    • 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

The company operates in the manufacturing sector focused on plastic machinery, serving industrial clients primarily in China. It maintains a direct sales business model with a product range including laminating machines and extrusion equipment. The website indicates a stable market position with recognized products and a 15-year manufacturing history, although domain registration inconsistencies suggest possible recent domain acquisition or alternate domain usage. The company has a network of partner sites linked as friendly links, indicating a collaborative ecosystem. Revenue streams likely derive from machinery sales and after-sales services. The website content and contact details support a credible business presence, but lack of formal privacy and security policies may impact customer trust.

Security posture

The current security maturity level is moderate. The website lacks HTTPS confirmation and security headers, which are critical for protecting user data and preventing common web attacks. The use of outdated JavaScript libraries increases vulnerability risk. No incident response or security policy information is provided, indicating limited preparedness for security incidents. Privacy compliance is weak, with no GDPR or cookie consent mechanisms detected. The site does not expose sensitive information but should prioritize implementing HTTPS, security headers, and formal privacy policies. Regular updates to libraries and inclusion of security contact channels would improve security culture and readiness.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate and enforce secure connections site-wide.
  2. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish comprehensive privacy and cookie policies with user consent mechanisms to improve compliance.
  4. Update all JavaScript libraries to current secure versions to mitigate vulnerabilities.
  5. Establish and display incident response contact information to enhance security transparency and readiness.

Technical notes

Notes

The website uses a mix of legacy and modern front-end technologies including jQuery 1.8.3, Swiper.js, Slick Carousel, WOW.js, and Layer.js. The HTML structure is valid with meta tags for SEO but lacks advanced accessibility features. Performance is moderate with some optimization opportunities, especially for mobile responsiveness. No CMS or hosting provider information is evident. The site integrates Baidu Analytics and Baidu Share for tracking and marketing. Technical debt is present due to outdated libraries and missing security best practices. Modernization efforts should focus on upgrading libraries, improving mobile optimization, and enhancing security configurations to reduce technical 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.
