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

深圳市纵横通信息技术有限公司 operates a professional website focused on industrial monitoring solutions, specializing in dynamic environment monitoring systems and intelligent air conditioning controllers. With 19 years of industry experience, the company positions itself as a leading manufacturer and solution provider in the energy and telecommunications sectors, serving system integrators and enterprise clients across China. The website showcases a comprehensive product catalog, solution offerings, and multiple regional service centers, reflecting a mature business model with direct sales and localized support. Technically, the website employs standard web technologies including HTML5, CSS3, JavaScript, and jQuery, supplemented by analytics and tracking services from Baidu and SensorsData. Hosting is provided via Baidu Cloud CDN, ensuring moderate performance and basic mobile optimization. SEO practices are good with proper meta tags and structured navigation, although accessibility features are basic. From a security perspective, the site uses HTTPS with a valid certificate and has a clean domain registration history dating back to 2008, consistent with the company's claimed operational history. However, there are gaps such as lack of DNSSEC, missing Content-Security-Policy headers, and absence of published security policies or incident response contacts. Privacy compliance is limited, with no visible cookie consent mechanisms or GDPR indicators, which could pose regulatory risks. Overall, the website is professional and trustworthy with strong business credibility but would benefit from enhanced security headers, privacy compliance improvements, and transparent incident response information to strengthen its security posture 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

7 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. 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';…

  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

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 is well-established in the industrial monitoring market, focusing on energy and telecommunications sectors. It leverages direct manufacturing and sales with a strong regional presence across China, supported by multiple service centers and offices. The business model emphasizes custom solutions and after-sales support, targeting system integrators and enterprise customers. The company demonstrates competitive advantages through long-term industry experience, proprietary hardware and software development, and ISO9001 quality certification. Growth indicators include extensive product lines, numerous customer case studies, and a large partner network. Strategic observations highlight the importance of expanding privacy and security compliance to maintain market trust and meet evolving regulatory requirements.

Security posture

The website exhibits a moderate security maturity level with HTTPS enforced and no visible exposure of sensitive data. However, the absence of DNSSEC, missing Content-Security-Policy headers, and lack of published security or incident response policies indicate areas for improvement. The use of multiple third-party analytics and tracking scripts without explicit cookie consent raises privacy concerns. There is no evidence of vulnerability disclosures or security.txt files, which limits transparency and incident readiness. Compliance with GDPR and other data protection regulations appears minimal. Enhancing security headers, implementing privacy mechanisms, and publishing clear security policies would significantly improve the security posture and reduce potential risks.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and enforce a Content-Security-Policy header to mitigate cross-site scripting and related attacks.
  3. Publish a comprehensive security policy and incident response contact information on the website.
  4. Add a cookie consent banner/mechanism to comply with privacy regulations and inform users about tracking.
  5. Regularly audit and update third-party scripts to minimize vulnerabilities and privacy risks.

Technical notes

Notes

The website uses a standard and stable technology stack with HTML5, CSS3, JavaScript, and jQuery. It integrates analytics and tracking tools from Baidu and SensorsData, hosted on Baidu Cloud CDN, which provides moderate performance. The site is mobile-optimized at a basic level and has good SEO practices with meta tags and structured navigation. There is no indication of a popular CMS, suggesting a custom or proprietary content management system. Technical debt is low, but opportunities exist to modernize security headers and improve privacy compliance. The site’s infrastructure supports its business operations adequately but should evolve to meet higher security and privacy standards.
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.
