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

株式会社カカオピッコマ operates a corporate website primarily in Japanese, representing a medium-sized technology company specializing in digital content distribution, specifically electronic manga and novels through its flagship service 'ピッコマ'. The website provides comprehensive corporate information, service details, news updates, recruitment information, and security and privacy policies, targeting general users and potential employees in Japan. The company positions itself as a leading player in the domestic digital manga and novel market, supported by ISMS certification and consistent branding. Technically, the website is built on WordPress with a custom theme, utilizing modern JavaScript libraries such as jQuery and Slick Carousel for UI components. It integrates Google Analytics and Google Tag Manager for user tracking and marketing analytics. The site is mobile-optimized with responsive design elements and includes proper meta tags for SEO. However, accessibility features are basic, and no JSON-LD structured data is present. From a security perspective, the site enforces HTTPS and demonstrates good security posture with ISMS certification. However, it lacks visible security headers and a cookie consent mechanism, which are important for privacy compliance. The absence of WHOIS registration data raises concerns about domain legitimacy, although the professional presentation and certifications mitigate some risk. No contact emails or phone numbers are explicitly provided on the homepage, limiting direct communication channels. Overall, the website is professional, content-rich, and technically sound but would benefit from enhanced privacy compliance measures, improved transparency in contact information, and verification of domain registration details to strengthen trust and security 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

6 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 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.

Business context

Business profile

Kakao Piccoma Corp. operates in the technology sector focusing on digital content delivery, specifically electronic manga and novels. The company leverages a freemium model with its '待てば無料で読める「ピッコマ」' service, attracting a broad user base interested in manga and novel content. The corporate website serves multiple audiences including consumers, business partners, and job seekers, indicating a diversified engagement strategy. The presence of ISMS certification and a dedicated security policy reflects a commitment to information security, which is a competitive advantage in digital content markets. The company’s partnership with KADOKAWA for content development suggests strategic alliances enhancing content offerings. The website’s integration of Google Analytics and Tag Manager supports data-driven marketing and user engagement optimization. However, the lack of visible contact details and WHOIS data may pose challenges in trust and transparency, which are critical in digital content distribution and recruitment.

Security posture

The website demonstrates a moderate to strong security posture with HTTPS enforced and ISMS certification indicated, reflecting adherence to recognized information security standards. However, the absence of visible security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web vulnerabilities. The lack of a cookie consent mechanism and explicit privacy compliance disclosures may expose the company to regulatory risks, especially under GDPR or similar frameworks. No incident response contacts or vulnerability disclosure policies are publicly available, which could delay response to security incidents. The missing WHOIS data is a notable concern, potentially indicating domain registration issues or privacy protection that is not clearly justified. Overall, while the site is secure in transport and certified, improvements in transparency, privacy compliance, and security header implementation are recommended to enhance the security maturity level.

Recommendations

  1. Implement a visible cookie consent banner and detailed cookie policy to ensure privacy compliance.
  2. Publish clear contact information including security incident response contacts and data protection officer details.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the website against common attacks.
  4. Verify and disclose domain registration details to improve legitimacy and trustworthiness.
  5. Enhance accessibility features to improve user experience and compliance with accessibility standards.

Technical notes

Notes

The website is built on WordPress with a custom theme, leveraging jQuery and Slick Carousel for interactive UI components. It uses Google Tag Manager and Google Analytics for tracking and marketing analytics. The site is mobile responsive with appropriate viewport settings and meta tags for SEO. Performance is moderate with asynchronous loading of analytics scripts. No JSON-LD structured data is present, which could be added to improve SEO and rich snippet eligibility. The site lacks visible security headers, which is a technical gap. Hosting provider details are not disclosed. Overall, the technical implementation is solid but could benefit from enhanced security headers, structured data, and improved accessibility compliance.
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.
