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

北京牛客科技有限公司 is a Beijing-based technology company specializing in paid information services and technology education content primarily targeting Chinese-speaking professionals and learners. The company has an established market presence since its domain registration in 2015 and operates a professionally designed website using modern web technologies such as Vue.js, hosted on Alibaba Cloud infrastructure. The website content is relevant, well-structured, and optimized for mobile devices, providing a good user experience. From a technical perspective, the site employs modern JavaScript frameworks and uses Alibaba Cloud DNS services but lacks advanced DNS security features such as DNSSEC. The website is served over HTTPS, ensuring basic transport security, but it does not implement important security headers, which could improve protection against common web attacks. Analytics tracking is implemented via GrowingIO, but no cookie consent or privacy policies are present, indicating gaps in privacy compliance. Security posture is moderate with no visible vulnerabilities or exposed sensitive data; however, the absence of security policies, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in security governance. The domain WHOIS data aligns well with the business claims, showing consistent registration details and a legitimate operational history. Overall, the website is professional and trustworthy but would benefit from enhanced security controls, privacy compliance measures, and transparency to strengthen user trust and regulatory adherence.

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. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  2. 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

北京牛客科技有限公司 operates in the technology sector, focusing on paid information and educational content services. The company targets technology professionals and learners in China, leveraging a business model based on subscription or paid access to specialized content. The market position appears stable with a medium-sized operation founded in 2015. The company maintains a consistent brand presence and uses Alibaba Cloud services, indicating a partnership ecosystem with major cloud providers. Revenue streams likely include paid content subscriptions and possibly technology service offerings. The website's professional design and clear contact information support credibility and customer engagement. Growth indicators include the use of modern web technologies and analytics tools, though the lack of privacy and security policies may pose risks to scaling and compliance in regulated markets.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and no immediate vulnerabilities detected in the content or scripts. However, the absence of DNSSEC, security headers, and formal security policies indicates gaps in defense-in-depth strategies. There is no evidence of incident response readiness or vulnerability disclosure programs, which are critical for timely handling of security incidents. Privacy compliance is weak due to missing privacy and cookie policies and lack of GDPR indicators. The use of third-party analytics without consent mechanisms further exposes privacy risks. Overall, the security culture appears nascent, with opportunities to implement best practices and improve transparency to users and regulators.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement essential security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish comprehensive privacy and cookie policies and implement a consent mechanism to comply with GDPR and other privacy regulations.
  4. Establish and publish incident response contact information and a vulnerability disclosure policy to improve security governance and user trust.
  5. Enhance accessibility features and SEO optimization to improve user experience and search engine visibility.

Technical notes

Notes

The website is built using Vue.js, a modern JavaScript framework, and is hosted on Alibaba Cloud infrastructure, indicating a contemporary and scalable technical foundation. The site loads multiple deferred JavaScript chunks and CSS files, suggesting modular and optimized resource loading. Mobile optimization is good, with responsive font sizing and viewport settings. However, the absence of CMS identification suggests a custom or proprietary platform. Performance is moderate, with no explicit indicators of slow loading but no advanced performance optimizations detected. The lack of accessibility features beyond basic viewport settings indicates room for improvement in inclusivity. SEO is basic, with minimal meta tags and no structured data such as JSON-LD or Open Graph tags detected.
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.
