NIS2 and GDPR posture

GDPR outside view
50/ 100 · Medium
Checks completed
7of 7

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

7 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. 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 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

    • 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

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

该公司在环保和机器视觉领域拥有明确的市场定位，专注于工业和城市环境监测系统的研发与供应。其业务模式为B2B，主要客户为政府监管机构和工业企业。公司成立于2003年，资产规模和员工数量显示为中型企业。网站展示了多个行业案例和产品解决方案，体现出较强的技术实力和行业经验。合作伙伴和友情链接涵盖相关环保及工业领域，显示一定的行业生态圈。缺乏公开的安全认证和隐私合规声明，可能影响部分客户的信任。整体业务表现专业且稳定，具备一定的市场竞争力。

Security posture

网站采用HTTPS保障数据传输安全，但未检测到常见的安全HTTP头部（如CSP、HSTS等），存在潜在的安全加固空间。未发现敏感信息泄露或明显漏洞，表明基础安全措施到位。缺少隐私政策和漏洞披露渠道，显示合规和事件响应准备不足。网站表单简单，未明确显示安全防护措施。建议引入安全头部配置，完善隐私合规文档，建立漏洞响应机制，以提升整体安全成熟度和客户信任。

Recommendations

  1. 完善并公开隐私政策和Cookie政策，确保符合GDPR等法规要求
  2. 配置安全HTTP头部，如Content-Security-Policy和Strict-Transport-Security
  3. 建立并公布漏洞披露和事件响应流程，提升安全事件处理能力
  4. 核实并公开域名注册信息，确保域名合法性和透明度
  5. 增强网站无障碍访问和安全表单防护，提升用户体验和安全性

Technical notes

Notes

网站采用了现代前端技术栈，包括jQuery 3.7.0、WOW.js动画库、Swiper轮播组件及Fancybox图片展示插件，提升用户交互体验。集成百度统计用于流量分析。页面结构清晰，响应式设计良好，适配移动设备。未检测到使用主流CMS，可能为定制开发。性能表现中等，部分图片较大可能影响加载速度。缺少安全头部和隐私合规脚本，存在技术债务。建议优化图片资源，增强安全配置，提升整体技术架构的现代化水平。
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.
