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

NTTドコモビジネス is a major Japanese telecommunications and ICT service provider, formerly known as NTT Communications, rebranded in July 2025. The company offers a broad portfolio of services including cloud, 5G, IoT, AI, security, and mobile solutions targeting corporate clients and medium to small enterprises. The website reflects a mature, enterprise-grade digital presence with comprehensive service information and strong branding consistent with a leading telecommunications group in Japan. Technically, the site employs a modern technology stack with multiple analytics and marketing tools integrated, ensuring good SEO, accessibility, and mobile responsiveness. Security posture is solid with HTTPS enforced and no obvious vulnerabilities, though some security headers are not explicitly detected and incident response contact details are not publicly visible. Overall, the site is trustworthy and professional, though the lack of WHOIS data is unusual but likely due to registry privacy policies. Strategic recommendations include enhancing security header implementation, publishing explicit vulnerability disclosure policies, and improving transparency on privacy compliance and incident response.

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

4 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 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. 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 company holds a strong market position as a key player in Japan's telecommunications sector, leveraging its parent company NTT Docomo's brand and infrastructure. Its business model focuses on providing ICT and digital transformation solutions to enterprises, including cloud services, network infrastructure, mobile device management, and industry-specific solutions. The website's extensive service categorization and targeted content for various industries and business sizes indicate a well-segmented customer approach. Partnerships with global NTT services and innovation hubs like OPEN HUB suggest a strategic ecosystem fostering innovation and co-creation. The presence of online shops and self-service portals reflects a modern digital sales and support model. Growth indicators include emphasis on emerging technologies such as generative AI and 5G. The company appears well-positioned for continued leadership in the Japanese corporate ICT market.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no visible exposure of sensitive data. The use of reputable third-party analytics and marketing tools is balanced with privacy considerations, though explicit privacy compliance details could be improved. The absence of security.txt and vulnerability disclosure policies limits transparency for security researchers. No direct contact channels for incident response or abuse are found, which is a gap in security readiness communication. Security headers like Content-Security-Policy and X-Frame-Options are not explicitly detected in the provided data, suggesting room for enhancement. Overall, the site is secure for general users but could benefit from improved security best practices and clearer communication on security policies.

Recommendations

  1. Implement and enforce comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
  3. Provide explicit incident response contact information on the website to improve security communication.
  4. Enhance privacy compliance transparency by detailing GDPR and other relevant regulations adherence.
  5. Regularly audit and update third-party scripts to mitigate risks from external dependencies.

Technical notes

Notes

The website uses a modern JavaScript stack including jQuery, Swiper.js for UI components, and integrates multiple marketing and analytics platforms such as Google Analytics, Marketo, Tealium, Eloqua, Ptengine, and Microsoft Clarity. The site is mobile-optimized with responsive CSS and accessibility features like focus outlines. Performance is moderate, likely impacted by the number of external scripts loaded asynchronously. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not evident from the data. The site structure is well-organized with clear navigation and semantic HTML elements. Technical risks include reliance on multiple third-party scripts which require ongoing security management. Overall, the technical infrastructure supports a professional and scalable corporate website.
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.
