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

The website lychengkao.com represents a newly established adult education service provider based in Linyi, China, specializing in adult higher education, exam preparation, and degree advancement services. The business targets adult learners in the Linyi region seeking convenient and professional assistance with adult college entrance exams and related certifications. The site offers online registration, downloadable materials, and information on various educational programs and institutions. Technically, the website employs a basic jQuery-based frontend with sliders and menus, hosted on Alibaba Cloud. While the site is accessible and uses HTTPS, it lacks advanced security headers and privacy compliance mechanisms such as privacy and cookie policies. The domain is very new, consistent with the business's recent founding, and registered with a reputable registrar without privacy protection. Overall, the site provides relevant educational content but requires improvements in security and privacy compliance to enhance 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. 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. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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';…

  4. 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

Lychengkao.com operates as a small, regionally focused education service provider in the adult education sector. Its competitive advantage lies in localized expertise and a comprehensive offering of adult education services including exam preparation, vocational skills, and professional certification guidance. The business model is service-oriented, relying on registrations and educational consulting. The target customer segment is adult learners in Linyi and surrounding areas. The website's partnership ecosystem includes several related local education and exam preparation sites linked as friendly sites. Growth indicators include recent domain registration and active content updates. Strategic observations suggest the business is in early stages and should focus on building trust through enhanced compliance and security.

Security posture

The website demonstrates a basic security posture with HTTPS enabled but lacks critical security headers such as Content-Security-Policy, HSTS, and X-Frame-Options. No WAF or bot protection mechanisms are detected. The absence of privacy and cookie policies indicates compliance gaps with GDPR and related regulations. No incident response or vulnerability disclosure information is provided. The site does not expose sensitive data or show signs of vulnerabilities in the visible content. Overall, the security maturity is low to moderate, suitable for a small educational site but requiring improvements to mitigate risks and enhance user trust.

Recommendations

  1. Implement comprehensive privacy and cookie policies to improve regulatory compliance and user trust.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and HSTS to strengthen security posture.
  3. Enable DNSSEC for the domain to enhance DNS security.
  4. Introduce an incident response contact or abuse email to facilitate vulnerability reporting and incident management.
  5. Improve mobile optimization and accessibility to enhance user experience and broaden audience reach.

Technical notes

Notes

The website uses a traditional jQuery-based frontend with slider and menu plugins, indicating a legacy or custom-built CMS without modern frameworks. Hosting is provided by Alibaba Cloud, a reputable provider. Performance is moderate with no advanced optimization detected. SEO is basic with meta keywords and description present but no structured data or Open Graph tags. Accessibility and mobile responsiveness are basic, with room for improvement. No analytics or tracking scripts are detected, indicating minimal user tracking. Technical debt is moderate due to lack of modern frameworks and security best practices. Modernization opportunities include adopting responsive design frameworks, implementing SEO structured data, and enhancing 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.
