NIS2 Art. 21(2)

  1. (a) Risk analysis and security policies: Not visible from outside
  2. (b) Incident handling: One indicator
  3. (c) Business continuity, backups and crisis management: Not visible from outside
  4. (d) Supply chain security: Not visible from outside
  5. (e) Secure acquisition, development and maintenance, including vulnerability handling: Partly checked
  6. (f) Assessing the effectiveness of security measures: Not visible from outside
  7. (g) Cyber hygiene and security training: Not visible from outside
  8. (h) Cryptography and encryption: Partly checked
  9. (i) HR security, access control and asset management: One indicator
  10. (j) Multi-factor authentication and secured communications: Not visible from outside

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

4 findings rated critical or high. Fix these first.

  1. 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

  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.

    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 10 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

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

该公司定位为专业制造商，市场定位明确，拥有稳定的客户群体和行业认可。其业务模式以制造和销售为主，辅以定制化服务，覆盖工业控制、显示屏、亮化等多个细分市场。公司通过与科研机构合作，建立研发中心，增强技术竞争力。网站展示了丰富的客户案例和产品线，反映出较强的市场执行力和品牌建设。合作伙伴网站链接显示其在行业内有一定的生态合作网络。缺乏公开的财务数据和更详细的市场份额信息，限制了更深入的商业分析。

Security posture

网站采用HTTPS保障数据传输安全，未检测到明显的安全漏洞或敏感信息泄露。使用的JavaScript库版本较旧，可能存在安全隐患。缺少安全相关HTTP头部配置，降低了防护能力。未发现隐私政策和安全事件响应信息，表明合规和安全管理尚需加强。建议引入内容安全策略（CSP）、X-Frame-Options等安全头，更新依赖库，并完善隐私及安全响应文档以提升整体安全成熟度。

Recommendations

  1. 制定并公开隐私政策和Cookie政策，提升合规性。
  2. 增加安全HTTP头部配置，如Content-Security-Policy和X-Frame-Options。
  3. 升级JavaScript库版本，减少潜在安全风险。
  4. 建立安全事件响应流程并公开相关联系方式。
  5. 增强网站无障碍访问性，满足更广泛用户需求。

Technical notes

Notes

网站基于传统的前端技术栈，使用jQuery 1.8.3和Swiper等库，整体架构较为稳定但技术较为陈旧。无明显CMS品牌标识，推测为定制开发。网站响应速度适中，移动端优化良好，具备基础SEO元素。缺少结构化数据和现代前端框架支持，存在技术升级空间。安全配置不足，未见安全头和隐私合规措施。建议逐步引入现代前端技术和安全最佳实践，提升用户体验和安全保障。
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.
