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

Wisdom House (주)위즈덤하우스 is a Korean publishing company specializing in books, webtoons, and web novels, operating since 2011. The website serves as a platform to introduce new works and provide customer inquiries, targeting a general audience interested in media content. The company maintains a consistent brand presence with official social media channels and a domain registration that aligns with its business identity. Technically, the website uses a moderate technology stack including jQuery, Google Analytics, Google Tag Manager, and SDKs for Kakao, Naver login, and Iamport payment integration. The site is moderately optimized for performance and mobile use but lacks advanced accessibility and SEO features. No CMS or hosting provider details were identified. From a security perspective, the site uses HTTPS and common third-party scripts but lacks visible security headers and published privacy or cookie policies, indicating room for improvement in compliance and security best practices. No forms or sensitive data exposure were detected, and no WAF or blocking mechanisms are present, allowing full content access. Overall, the website is moderately professional and trustworthy but would benefit from enhanced privacy compliance, security hardening, and improved user experience features to strengthen its digital maturity and risk posture.

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. 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

  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

Wisdom House holds an established position in the Korean media publishing sector, focusing on books, webtoons, and web novels. Its business model revolves around content creation and distribution, targeting readers and digital consumers of Korean literature and comics. The company leverages social media platforms for marketing and customer engagement but lacks visible e-commerce or subscription services on the homepage. The domain age and registrant data support a stable operational history. Growth opportunities include expanding digital offerings and improving online user engagement through enhanced website features and compliance. Partnerships with major Korean platforms like Kakao and Naver for login and payment integration suggest a strategic ecosystem alignment. However, the absence of detailed business information and contact channels on the website limits transparency and potential customer trust.

Security posture

The current security posture is basic with HTTPS enabled and no detected blocking or WAF interference. However, the absence of security headers such as Content Security Policy, X-Frame-Options, and HSTS reduces protection against common web attacks. No privacy or cookie policies are published, which is a compliance gap especially under GDPR or similar regulations. The lack of incident response contact information and vulnerability disclosure mechanisms further limits the site's security maturity. No vulnerable libraries or exposed sensitive data were identified in the provided content. Overall, the site is functional but requires significant improvements in security best practices and compliance documentation to reduce risk.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Add security headers including Content Security Policy, X-Frame-Options, and HSTS to enhance protection against web attacks.
  3. Provide clear contact information including phone numbers and a contact form on the website for better customer support and transparency.
  4. Establish and publish an incident response policy and vulnerability disclosure program to demonstrate security readiness.
  5. Improve mobile optimization and accessibility features to enhance user experience and SEO performance.

Technical notes

Notes

The website employs a traditional JavaScript stack with jQuery and integrates multiple third-party SDKs for analytics, social login, and payment processing. The use of Google Analytics and Tag Manager indicates moderate tracking and marketing capabilities. The site loads scripts asynchronously and preloads CSS and JS assets, suggesting some performance optimization. However, no modern frameworks or CMS platforms were detected, which may indicate a custom or legacy build. The absence of detected hosting provider information limits infrastructure assessment. The site’s mobile optimization and accessibility are basic, with no advanced ARIA or semantic HTML features observed. Overall, the technical infrastructure is functional 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.
