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

ZG·言語学習 is a Japanese language learning and linguistic research website offering categorized educational content focused on linguistics and language studies. The site targets language learners and researchers interested in theoretical and applied linguistics, language culture, and language resources. The business model appears to be content provision without direct commercial services or e-commerce. The website is small-scale and niche-focused with basic content quality and moderate branding consistency. Technically, the website uses simple HTML and CSS without modern frameworks or CMS detected. The site is moderately optimized for mobile and SEO but lacks advanced technical features or performance optimizations. No external scripts or analytics services are detected, indicating minimal tracking or data collection. From a security perspective, the site lacks HTTPS information in the provided data, no security headers, and no privacy or cookie policies, which are critical for compliance and user trust. The WHOIS data is missing or the domain appears unregistered, which raises legitimacy concerns despite the accessible content. No contact or incident response information is provided, limiting transparency. Overall, the website presents educational content safely but suffers from poor security posture, lack of compliance documentation, and questionable domain registration status. Strategic improvements in security, privacy, and transparency are recommended to enhance trust and compliance.

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

8 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 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';…

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 website operates in the education sector focusing on linguistics and language learning. It serves a niche audience of language learners and researchers primarily in Japanese. The business model is content-driven without evident monetization or commercial partnerships. The site links to related language and cultural domains, indicating a small partnership ecosystem. Growth indicators and company size are minimal, with no parent or subsidiary companies identified. The lack of contact information and WHOIS data transparency limits business credibility and trust. The site’s competitive advantage lies in its specialized linguistic content but is hindered by technical and security shortcomings.

Security posture

The current security maturity level is low due to missing HTTPS confirmation, absence of security headers, and no visible privacy or cookie policies. The lack of WHOIS registration data and domain legitimacy concerns further reduce trust. No incident response or vulnerability disclosure mechanisms are present. Data protection practices are minimal, and no compliance with GDPR or other frameworks is evident. The site does not collect user data via forms or analytics, reducing exposure but also limiting user engagement. Overall, the security posture requires significant improvements to meet modern standards and regulatory requirements.

Recommendations

  1. Implement HTTPS with a valid SSL certificate to secure user connections.
  2. Publish comprehensive privacy and cookie policies to comply with GDPR and other regulations.
  3. Add clear contact information including emails and phone numbers for user support and incident response.
  4. Configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Verify and update WHOIS registration information to improve domain legitimacy and trust.

Technical notes

Notes

The website is built with basic HTML and CSS without modern JavaScript frameworks or CMS platforms. It lacks external scripts, analytics, or tracking technologies, indicating a simple technical infrastructure. Mobile optimization and SEO are basic but functional. Performance is moderate with no explicit indicators of slow loading. The absence of security headers and HTTPS information suggests technical debt in security implementation. There is an opportunity to modernize the tech stack, improve accessibility, and enhance SEO and performance metrics to better serve users and improve search rankings.
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.
