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

The website www.casteaside.com is a Japanese language affiliate marketing site focused on recommending hair shampoos that improve hair volume and strength. It targets middle-aged to older adults of both genders interested in hair care products. The site provides product rankings and affiliate links to purchase recommended shampoos. Technically, the site uses basic HTML, CSS, and JavaScript with no detected CMS or advanced frameworks. The site is moderately optimized for mobile and SEO but lacks modern security features such as HTTPS and security headers. No privacy or cookie policies are present, and contact information is limited to a contact form. The WHOIS data for the domain is unavailable, indicating potential registration or legitimacy concerns. Overall, the site has moderate content quality but significant security and compliance gaps.

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. 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 business operates in the retail sector, specifically in hair care product recommendations via affiliate marketing. Its market position is niche, targeting Japanese consumers aged 40-60+. Revenue likely derives from affiliate commissions. The site links to multiple external domains related to affiliate networks and product suppliers. The lack of clear company information and WHOIS data reduces transparency. The business model is content-driven with monetization through affiliate programs. Growth potential depends on SEO and trust-building. Partnerships appear limited to affiliate networks. The site lacks certifications or trust seals, which may impact user confidence.

Security posture

The website currently exhibits a low security maturity level. It lacks HTTPS, security headers, and privacy compliance mechanisms. No incident response or security policy information is provided. The use of third-party tracking scripts without clear privacy disclosures raises compliance concerns under GDPR and similar regulations. The absence of WHOIS data further reduces trust. There are no visible vulnerabilities but the lack of basic security controls is a significant risk. The site should prioritize implementing HTTPS, security headers, and privacy policies to improve security posture and regulatory compliance.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate to secure user data and improve trust.
  2. Add comprehensive privacy and cookie policies to comply with GDPR and other privacy regulations.
  3. Publish clear contact information including company emails and phone numbers to enhance credibility.
  4. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Conduct a full security audit and vulnerability assessment to identify and remediate potential risks.

Technical notes

Notes

The website uses basic web technologies (HTML, CSS, JavaScript) without a detectable CMS or advanced frameworks. The charset is Shift_JIS, which may limit compatibility and SEO effectiveness. Performance appears moderate but could be improved with modern optimization techniques. Mobile optimization is basic, and accessibility features are minimal. The site relies on external affiliate networks and tracking scripts, which should be managed carefully to avoid privacy issues. Hosting provider and infrastructure details are not available. Overall, the technical implementation is functional but dated and lacking modern best practices.
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.
