57/100

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

常州市长城屏蔽科技有限公司 operates as a specialized manufacturer and provider of electromagnetic shielding rooms and related products, targeting government, military, defense research, and financial institutions requiring secure data centers and electromagnetic protection. The website presents a professional image with detailed product and solution descriptions, showcasing expertise in high-voltage shielding halls, anechoic chambers, and secure meeting rooms. The company positions itself as a key player in the electromagnetic shielding industry within China. Technically, the website employs legacy technologies such as jQuery 1.8.3 and Bootstrap, with integration of Baidu Analytics and CNZZ for user tracking. The site is mobile-optimized and structured with clear navigation, though some modern security best practices like updated libraries and security headers are lacking. The absence of privacy and cookie policies indicates room for improvement in compliance and user transparency. From a security perspective, HTTPS is enforced and contact forms include CAPTCHA validation, but the use of outdated JavaScript libraries and missing security headers present vulnerabilities. The WHOIS data is unavailable or inconsistent, which raises concerns about domain legitimacy despite the professional website content. Overall, the security posture is moderate but requires enhancements to align with best practices. Strategically, the company should prioritize updating its technical stack, implementing comprehensive privacy and cookie policies, and improving security headers to strengthen trust and compliance. Addressing WHOIS transparency and enhancing incident response information would further solidify its credibility and security readiness.

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

  • 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 targets a niche market focused on electromagnetic shielding solutions for sensitive and secure environments, including classified data centers and high-voltage testing facilities. Its competitive advantage lies in specialized product offerings and compliance with national security standards. The business model revolves around manufacturing and direct sales, supported by case studies and client showcases. The presence of multiple partner domains suggests an established ecosystem. Growth indicators include active news updates and product diversification. However, the lack of detailed founding year and parent company information limits full business profiling.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforcement and CAPTCHA-protected forms. However, the use of an outdated jQuery version exposes it to known vulnerabilities, and the absence of key security headers reduces protection against common web attacks. No explicit security or incident response policies are published, and GDPR compliance is not evident. Data protection officer contact and vulnerability disclosure mechanisms are missing, indicating gaps in security governance. These factors collectively suggest a need for improved security controls and transparency to mitigate risks and enhance trust.

Recommendations

  1. Upgrade all JavaScript libraries, especially jQuery, to current secure versions to mitigate known vulnerabilities.
  2. Publish comprehensive privacy and cookie policies to improve compliance and user trust.
  3. Implement essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Enhance transparency by providing incident response contacts and vulnerability disclosure information.
  5. Clarify WHOIS registration details or ensure domain registration data is publicly available to improve legitimacy perception.

Technical notes

Notes

The website uses a traditional tech stack with Bootstrap for responsive design and jQuery 1.8.3 for scripting, which is outdated and poses security risks. It integrates Baidu Analytics and CNZZ for tracking, and OneAll for social media plugins. The site is moderately performant with good mobile optimization but lacks advanced accessibility features. SEO is basic with meta tags and Open Graph data present but no structured JSON-LD data found. Hosting provider details are not discernible from the content. Overall, the technical infrastructure is functional but requires modernization to meet current web standards and security expectations.
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.
