岳阳链天下网络科技有限公司是一家专注于为企业官网提供网站托管、优化及代运营服务的专业公司，成立于2012年，拥有超过5000家企业客户。其业务涵盖企业网站建设、网站维护托管、SEO优化外包、友情链接管理、原创文章代写及品牌推广等，定位为专业的企业网站运营托管外包服务商。网站内容丰富，结构清晰，面向中国企业客户，提供高性价比的服务方案。 技术基础方面，网站采用了jQuery库和百度统计进行用户行为分析，整体性能表现适中，具备良好的移动端适配和基础的SEO优化。网站未检测到使用主流CMS，托管和服务器信息未明确，安全配置方面缺少安全HTTP头，SSL配置未明确，存在提升空间。 安全态势显示网站未公开隐私政策和Cookie政策，缺乏安全事件响应渠道，WHOIS信息缺失导致域名注册合法性存疑，降低了整体信任度。网站无明显安全漏洞暴露，但建议加强安全头配置和合规性文档完善。 总体风险评估为中等，建议加强域名注册信息透明度，完善隐私及安全政策，强化安全配置，提升用户信任和合规水平。

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

该公司在中国市场定位为中小型企业网站托管及SEO优化服务提供商，拥有稳定的客户基础和丰富的服务项目，涵盖网站建设、维护、内容更新及品牌推广。其商业模式为服务外包，收入来源主要依赖于托管服务费和SEO优化外包。合作伙伴网络广泛，涵盖多个相关行业网站，增强市场渗透力。公司通过提供多样化的SEO及内容服务，满足不同企业客户的需求，具备一定的竞争优势。未来增长潜力依赖于提升品牌信任度和合规性。 技术和市场策略侧重于成本效益和快速上线，适合中小企业客户。缺乏公开的财务和注册透明度信息，建议加强企业信息披露以提升市场竞争力。

Security posture

当前安全成熟度处于基础水平，网站启用了HTTPS（通过外部资源链接推断），但未检测到关键安全HTTP头如Content-Security-Policy、X-Frame-Options等，存在潜在的安全风险。缺少隐私政策和Cookie政策，可能导致合规风险。未发现公开的安全事件响应联系方式，降低了事件处理效率。WHOIS信息缺失增加了域名合法性风险。建议加强安全头配置，完善隐私合规文档，建立安全事件响应机制，定期审计第三方脚本，提升整体安全文化和防护能力。

Recommendations

  1. 完善并公开隐私政策和Cookie政策，确保符合GDPR及相关法规要求。
  2. 配置并启用关键安全HTTP头，如Content-Security-Policy、X-Frame-Options和X-Content-Type-Options。
  3. 公开安全事件响应联系方式，建立快速响应机制以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，增强用户信任。
  5. 定期审计和更新第三方脚本，防止潜在的安全漏洞和数据泄露风险。

Technical notes

Notes

网站采用传统的HTML结构，使用jQuery库和百度统计脚本，技术栈较为基础。无明显现代前端框架或CMS系统，可能限制扩展性和维护效率。页面设计响应式良好，适配移动设备，SEO优化基础较好，包含关键词和描述元标签。性能表现中等，未检测到明显的加载瓶颈。建议考虑引入现代前端框架提升用户体验，优化服务器响应速度，增强技术架构的可维护性和安全性。
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.
