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

The website '临沂成人高考函授网' is a specialized adult education platform focused on providing adult higher education exam preparation, enrollment consulting, and vocational skills training primarily for the Linyi region in Shandong, China. The business is newly established in 2024 and targets adult learners seeking to improve their academic qualifications through correspondence and adult education programs. The site offers detailed information on courses, enrollment guides, policy updates, and showcases certificates and partner institutions, positioning itself as a regional education service provider. Technically, the website employs common JavaScript libraries such as jQuery and CSS frameworks like Pintuer, hosted on Alibaba Cloud. The site is mobile optimized with good navigation and content structure, though it lacks advanced CMS or modern frameworks. Performance is moderate, and SEO practices are adequately implemented. However, accessibility features are basic, and no analytics or tracking services are detected, indicating minimal user tracking. From a security perspective, the site uses HTTPS but lacks important security headers such as CSP and HSTS. There is no privacy or cookie policy, which is a compliance gap, especially under GDPR. Forms use GET methods for search inputs, which is less secure. The WHOIS data shows a consistent and legitimate domain registration with Alibaba Cloud, appropriate for the business age and type. No WAF or blocking mechanisms are detected, and the content is safe with no adult or explicit material. Overall, the website is functional and credible for its educational purpose but requires improvements in privacy compliance and security hardening to enhance trust and protect user data effectively.

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

The business operates in the adult education sector, focusing on exam preparation and enrollment consulting for adult learners in Linyi, China. It leverages partnerships with local universities and vocational institutions to offer recognized programs. The business model is service-oriented, generating revenue through education consulting and training services. Market positioning is regional and niche, targeting adult learners seeking flexible education paths. The company shows growth potential given the increasing demand for adult education in China. The partnership ecosystem includes related education portals and local institutions, enhancing its service offerings and reach.

Security posture

The current security posture is moderate but with notable gaps. HTTPS is used, ensuring encrypted communication. However, the absence of security headers like Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces protection against common web attacks. No privacy or cookie policies are present, indicating non-compliance with privacy regulations such as GDPR. Forms use GET methods, which may expose user input in URLs. No incident response or security contact information is provided. The site does not employ advanced security frameworks or vulnerability disclosure mechanisms. Overall, the security maturity is basic and requires enhancements to meet modern standards.

Recommendations

  1. Implement comprehensive privacy and cookie policies with user consent mechanisms to comply with GDPR and other privacy laws.
  2. Add essential security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to improve security posture.
  3. Change form methods from GET to POST for any user input forms to enhance data security.
  4. Enable DNSSEC for the domain to improve DNS security and prevent spoofing.
  5. Establish an incident response contact channel and consider publishing a vulnerability disclosure policy to build trust.

Technical notes

Notes

The website uses a traditional tech stack with jQuery and Pintuer CSS framework, indicating a custom or legacy development approach rather than modern SPA frameworks. Hosting is on Alibaba Cloud, a reputable provider. The site is mobile optimized and SEO friendly with proper meta tags and structured navigation. Performance is moderate, with no major issues detected. However, the lack of modern security headers and privacy compliance features indicates technical debt and areas for modernization. No CMS or advanced platform detected, suggesting manual content management. The site could benefit from adopting modern frameworks and security best practices to improve maintainability and security.
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.
