The website reflects a mature digital presence with comprehensive content, clear navigation, and consistent branding. Technically, the site uses modern JavaScript libraries, Google Analytics, and OneTrust for cookie consent, hosted on Amazon AWS infrastructure.

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

3 findings rated critical or high. Fix these first.

  1. 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 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';…

  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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Otsuka Holdings maintains a diversified portfolio in healthcare, leveraging subsidiaries such as Otsuka Pharmaceutical and Taiho Pharmaceutical. The business model focuses on innovation in pharmaceuticals and functional products to support global health. The company targets a broad audience including investors, partners, and consumers interested in health products. The website supports investor relations, sustainability, and corporate governance transparency. The presence of integrated reports and governance information indicates a mature corporate governance framework. The company benefits from a strong brand and extensive subsidiary network, enhancing market reach and operational capabilities.

Security posture

The website demonstrates a solid security foundation with HTTPS enabled and a robust cookie consent mechanism via OneTrust, supporting GDPR compliance. However, the absence of DNSSEC and security headers such as Content-Security-Policy and Strict-Transport-Security represents areas for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy or incident response contact limits transparency in security incident handling. Overall, the security posture is good but could be enhanced by adopting additional security best practices and publishing vulnerability disclosure information.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and verify security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  4. Provide explicit security policy and incident response contact information on the website.
  5. Continue monitoring and updating third-party libraries to avoid vulnerabilities.

Technical notes

Notes

The website uses a modern tech stack including jQuery 3.5.1, Google Tag Manager, Google Analytics, and OneTrust for cookie consent management. Hosting is via Amazon AWS, indicated by the AWS DNS nameservers. The site is mobile optimized with responsive design and viewport meta tags. SEO is supported by proper meta tags and Open Graph tags. Performance is moderate, with asynchronous loading of scripts and external resources. Accessibility features such as keyboard focus outlines and ARIA labels are present. No CMS was explicitly detected. The site could benefit from further technical enhancements such as improved security headers and DNSSEC implementation.
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.
