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

公司定位于工业锅炉制造领域，拥有稳定的客户基础和丰富的案例积累。通过与高校和科研机构合作，推动技术创新，提升核心竞争力。业务模式以制造和销售为主，目标客户为工业企业和供热行业。网站展示了多项行业认证和专利，增强了市场信任度。合作伙伴和友情链接显示其在行业内的良好合作网络。缺乏公开的隐私和安全政策可能影响部分客户的信任。整体业务表现稳健，具备中型企业规模特征。

Security posture

网站启用HTTPS，使用Cloudflare作为DNS和部分安全防护，但未启用DNSSEC，缺少关键安全HTTP头，未公开隐私政策和安全事件响应信息。无明显敏感信息泄露或漏洞迹象，使用的第三方库为主流且无已知漏洞。跟踪技术包括CNZZ和百度推送，用户隐私保护不足。建议补充安全头，启用DNSSEC，完善隐私和安全政策，提升整体安全成熟度和合规性。

Recommendations

  1. 启用DNSSEC以增强域名系统安全。
  2. 添加并公开隐私政策和Cookie政策，提升GDPR及相关法规合规性。
  3. 配置安全HTTP头（如Content-Security-Policy、X-Frame-Options等）以防止常见攻击。
  4. 建立并公开安全事件响应和漏洞披露渠道，增强安全透明度。
  5. 定期审查和更新第三方库，确保无已知漏洞，提升整体安全防护。

网站采用了jQuery、Bootstrap、OwlCarousel、Nivo Slider等成熟前端技术，页面结构清晰，支持移动设备访问。托管于使用Cloudflare DNS的环境，提升了基础设施稳定性和安全性。页面加载性能适中，SEO优化较好，包含丰富的元数据和关键词。缺少CMS信息，可能为定制开发。技术栈现代但存在安全配置不足，存在提升空间。整体技术架构适合中型制造企业的数字化需求。
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.
