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

The website www.sumi-takeshi.com is a Japanese-language affiliate marketing site focused on non-silicone shampoos, providing product rankings, reviews, and recommendations. It targets consumers interested in hair care, particularly those with sensitive scalp or hair damage concerns. The business model relies on affiliate commissions through links to product pages. Technically, the site uses basic HTML, CSS, and JavaScript with some tracking scripts for analytics. The site is moderately optimized for mobile and SEO but lacks advanced accessibility features. Security posture is weak due to missing HTTPS verification, absence of security headers, and no visible privacy or cookie policies. The WHOIS data is unavailable or indicates the domain is not registered, which raises legitimacy concerns. Overall, the site is functional but lacks transparency and robust security measures.

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

7 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 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';…

  2. 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

    • 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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The site occupies a niche retail segment focused on hair care product recommendations in Japan. It leverages affiliate marketing networks such as A8.net to monetize content. The target audience spans multiple age groups and includes men and women seeking non-silicone shampoo options. The site links extensively to external topical sites, possibly to increase SEO footprint or provide additional resources. There is no clear company or legal entity information, which limits business credibility. The lack of privacy and security policies may affect user trust and compliance with regulations such as GDPR.

Security posture

The security maturity level is low. The absence of HTTPS confirmation and security headers exposes users to potential risks. No contact emails for security or incident response are provided. The site uses third-party tracking scripts without visible consent mechanisms, indicating poor privacy compliance. The missing WHOIS data further complicates trust assessment. There are no visible vulnerabilities in the HTML content, but the overall security hygiene is weak, and improvements are necessary to protect user data and comply with privacy laws.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate and enforce secure connections.
  2. Add comprehensive privacy and cookie policies with clear user consent mechanisms.
  3. Publish contact information including security and incident response emails.
  4. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Verify and update WHOIS registration to ensure domain legitimacy and transparency.

Technical notes

Notes

The website is built with basic web technologies (HTML, CSS, JavaScript) without use of modern frameworks or CMS. It uses Shift_JIS charset which is uncommon and may affect SEO and accessibility. The site includes affiliate marketing scripts and tracking pixels from Research Artisan Pro. Performance appears moderate but could be improved with modern optimization techniques. Mobile optimization and accessibility are basic and could be enhanced for better user experience and compliance. No hosting provider or CMS information is discernible from the content.
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.
