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

深圳市凯丰盈科技有限公司 is a medium-sized manufacturing company specializing in the production and sale of illuminated tactile switches, button switches, key switches, and other electronic components. The company has over ten years of manufacturing experience and holds multiple certifications including ISO9001, UL, CUL, ENEC, CE, and CQC. Their products serve a broad range of industries such as medical equipment, instrumentation, consumer electronics, audio, communications, and computer hardware. The website content is professionally presented in Chinese and targets manufacturing and industrial clients. Technically, the website employs common front-end technologies such as jQuery, Font Awesome, Owl Carousel, and CSS Grid. The site is moderately performant and mobile-optimized with good SEO practices. However, there is no evidence of advanced frameworks or CMS usage. Security headers and HTTPS configuration details are not provided, indicating potential areas for improvement in security posture. From a security perspective, no critical vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of privacy and cookie policies, as well as missing WHOIS registration data, are notable concerns. The domain WHOIS query returned no registration information, which is inconsistent with the active and professional website presence, reducing overall trustworthiness. Overall, the website presents a legitimate manufacturing business with good content quality and business credibility but lacks transparency in domain registration and privacy compliance. Strategic improvements in security headers, privacy policies, and domain registration verification are recommended to enhance trust and compliance.

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

15 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. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Critical

      DNS Resolution Failed

      Unable to resolve domain A records

      What to do: Verify domain is properly configured and not expired

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: Telnet

      Port 23 (Telnet) is publicly accessible - Telnet - Unencrypted remote access

      What to do: Immediately restrict access to Telnet using firewall or VPN

    • Critical

      Critical Service Exposed: MSSQL

      Port 1433 (MSSQL) is publicly accessible - MSSQL - Database server

      What to do: Immediately restrict access to MSSQL using firewall or VPN

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 · found on this site
  • 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 as a direct manufacturer and seller of electronic switches and related components, serving multiple industrial sectors domestically and internationally. Their competitive advantages include a broad product range, recognized certifications, and a stable quality reputation. The business model focuses on manufacturing with a strong emphasis on quality control and customer service, including rapid sample delivery and reliable order fulfillment. The website indicates a well-established operation with a production base in Dongguan, China, and a workforce of over 300 employees. Partnerships and certifications support their market position. However, the lack of WHOIS data and privacy policies may impact customer trust and regulatory compliance.

Security posture

The website demonstrates a moderate security maturity level with no visible critical vulnerabilities or exposed sensitive information. However, the absence of security headers and privacy policies indicates gaps in security best practices and compliance. The missing WHOIS registration data raises concerns about domain legitimacy and potential risks. There is no evidence of incident response or vulnerability disclosure mechanisms. The site should implement HTTPS enforcement, security headers, and publish privacy and cookie policies to improve security posture and regulatory compliance. Regular audits of third-party scripts and enhanced transparency would further strengthen security culture.

Recommendations

  1. Implement and enforce HTTPS with strong SSL/TLS configuration.
  2. Add comprehensive privacy and cookie policies with clear consent mechanisms.
  3. Publish terms of service and incident response contact information.
  4. Deploy security headers such as Content-Security-Policy, X-Frame-Options, and HSTS.
  5. Verify and update domain WHOIS registration to ensure transparency and trust.

Technical notes

Notes

The website uses a traditional front-end stack with jQuery and CSS frameworks, providing a responsive and user-friendly interface. Performance is moderate with standard carousel and slide plugins. The site lacks modern JavaScript frameworks or CMS indicators, suggesting a custom or legacy build. SEO is supported by meta tags and structured navigation. Accessibility is basic but functional. There is no evidence of advanced hosting or CDN usage. Technical debt may exist due to missing security headers and lack of privacy compliance features. Opportunities exist to modernize the tech stack, improve security configurations, and enhance compliance features.
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.
