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

The website liuxueshengtutor.com operates as an online educational tutoring platform primarily targeting Chinese-speaking international students. It offers a comprehensive range of academic support services including essay, report, dissertation tutoring, coursework assistance, exam preparation, and academic appeal services. The site is well-structured with extensive categorized navigation reflecting a broad service offering tailored to various countries and academic disciplines. The business appears to be a small-sized entity founded in 2022, hosted by Alibaba Cloud, and focused on the education sector in China. Technically, the website employs standard web technologies such as HTML5, CSS3, and Swiper.js for UI components. It uses HTTPS with a valid SSL certificate, ensuring secure communication. The site is mobile-optimized and demonstrates good SEO practices with appropriate meta tags and Open Graph data. However, there is no evidence of advanced frameworks or CMS usage, and accessibility features are basic. From a security perspective, the site lacks several important security headers and does not have DNSSEC enabled, which could expose it to DNS spoofing risks. There is no visible privacy policy, cookie policy, or terms of service, indicating gaps in compliance with data protection regulations such as GDPR. No incident response or vulnerability disclosure information is provided, which limits transparency and preparedness for security incidents. Overall, the website is functional and professionally presented but requires improvements in privacy compliance, security hardening, and transparency to enhance trustworthiness and regulatory adherence. The risk level is moderate with no critical vulnerabilities detected but with room for security and compliance enhancements.

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

9 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 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';…

  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

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

Liuxueshengtutor.com positions itself as a specialized academic support service provider for international students, focusing on tutoring and academic appeals. Its competitive advantage lies in the breadth of services and detailed categorization by country and academic discipline, catering specifically to Chinese students studying abroad. The business model is service-based, likely generating revenue through tutoring fees and academic assistance. The target customers are international students facing academic challenges. The company appears to be in an early growth phase given its recent domain registration and small size. There is no evidence of partnerships or subsidiaries. The platform's extensive content and navigation suggest a strategy to capture a niche market in education support for Chinese students overseas.

Security posture

The website demonstrates a basic security posture with HTTPS enabled and valid SSL certificates, which is essential for secure data transmission. However, the absence of DNSSEC and security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options weakens its defense against common web attacks. The lack of privacy and cookie policies indicates non-compliance with GDPR and other data protection regulations. No incident response or abuse contact information is provided, which is a gap in security governance. No vulnerable libraries or exposed sensitive data were detected in the provided content. Overall, the security maturity is low to moderate, with recommendations to implement security headers, enable DNSSEC, and publish privacy and incident response policies.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement essential security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish comprehensive privacy and cookie policies to improve GDPR and data protection compliance.
  4. Add clear contact information including incident response and abuse contacts to enhance transparency and security readiness.
  5. Conduct a security audit to identify and remediate any potential vulnerabilities and improve overall security posture.

Technical notes

Notes

The website uses standard web technologies with no advanced frameworks detected. It is hosted on Alibaba Cloud, a reputable provider. The site is mobile-optimized and uses Swiper.js for interactive elements. Performance is moderate with no explicit indicators of slow loading or technical debt. SEO is supported by meta tags and Open Graph data. However, the lack of CMS or modern frameworks may limit scalability and ease of content management. Accessibility features are basic, suggesting potential improvements for users with disabilities. The technical infrastructure is adequate for a small educational service but could benefit from modernization and enhanced security configurations.
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.
