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

The website www.itheima.com represents 黑马程序员, a prominent IT training brand under the publicly listed company 传智教育. It offers a wide range of IT courses including Java, Python, AI, big data, front-end development, and specialized training such as 鸿蒙开发 and embedded systems. The platform targets students, professionals, and career changers seeking quality IT education and employment support. The site demonstrates strong market positioning with partnerships with major technology companies like Alibaba Cloud, Huawei, Tencent, and Baidu, enhancing its credibility and industry relevance. Technically, the website employs modern JavaScript libraries and analytics tools, ensuring a good user experience across desktop and mobile platforms. Security posture is adequate with HTTPS and no visible vulnerabilities, though improvements in security headers and explicit privacy consent mechanisms are recommended. Overall, the site is professional, content-rich, and trustworthy, though WHOIS data is unavailable, possibly due to privacy protection, which slightly impacts domain trust assessment.

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

黑马程序员 operates as a large-scale IT education provider in China, leveraging its parent company 传智教育's resources and stock market presence. Its business model focuses on comprehensive IT vocational training with a strong emphasis on AI and emerging technologies. The company maintains a broad geographic footprint with multiple campuses and VR tours, indicating significant investment in physical infrastructure. Strategic partnerships with leading tech firms provide competitive advantages in curriculum relevance and job placement. The brand's extensive course catalog and active community engagement suggest a mature and well-established operation with a focus on continuous innovation and market adaptation.

Security posture

The website maintains a good security baseline with enforced HTTPS and no exposed sensitive information in the HTML content. Use of reputable third-party analytics and chat services is noted, though the absence of explicit security headers such as CSP, HSTS, and X-Frame-Options is a gap. No public security policy or incident response contacts were found, which could be improved to enhance transparency and readiness. Privacy compliance is basic, with a privacy policy present but lacking cookie consent mechanisms. Overall, the security posture is solid for an educational platform but could benefit from enhanced header configurations and clearer privacy controls.

Recommendations

  1. Implement comprehensive security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to mitigate common web attacks.
  2. Add a visible cookie consent banner to comply with privacy regulations and improve user trust.
  3. Publish a dedicated security policy and provide clear incident response contact information to enhance transparency and preparedness.
  4. Regularly audit and update third-party scripts to minimize risks from external dependencies.
  5. Enhance accessibility features and mobile responsiveness to improve user experience across all devices.

Technical notes

Notes

The website uses a combination of jQuery, Swiper, and SuperSlide for UI interactions and sliders, supported by Baidu and Zhuge analytics for user tracking. The site is mobile-optimized with a redirect to a mobile subdomain. Performance is moderate with room for optimization. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting details are not disclosed. The site structure is well-organized with clear navigation and rich multimedia content. Technical debt appears low, but improvements in accessibility and security headers are recommended to align with modern best practices.
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.
