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

株式会社エイコーン is a small Japanese company specializing in the import, sale, and installation of high-quality Italian office and interior furniture products. Their business model includes comprehensive services from import to after-sales support, targeting offices, public facilities, commercial spaces, and residences across Japan. The website reflects a niche market position with a focus on quality and flexibility in customer service. Technically, the website uses a modern JavaScript stack including jQuery, bxSlider, and Google Tag Manager, hosted on a Japanese provider consistent with the company's location. The site is mobile-optimized and well-structured, though accessibility features are basic. Security posture is moderate; while HTTPS is presumed, DNSSEC is not enabled and security headers are absent. Privacy compliance is basic with a cookie consent banner and a privacy policy page, but no GDPR-specific statements or terms of service are present. Overall, the domain registration is consistent and transparent, supporting the legitimacy of the business.

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

5 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. 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

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality

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 operates in the Real Estate and Other sectors, focusing on furniture import and interior design services. Their competitive advantage lies in offering Italian high-end furniture with end-to-end service including design, import, installation, and maintenance. The target customers are corporate offices, public institutions, commercial facilities, and residential clients in Japan. The partnership with multiple Italian furniture brands enhances their market credibility. The business is relatively new (established 2021) and small in size, with no parent or subsidiary companies identified. The website content and branding are consistent and professional, supporting trustworthiness in their niche market.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is assumed but not explicitly confirmed. The absence of DNSSEC and security headers reduces the overall security posture. No forms or inputs that could expose vulnerabilities are present, and no sensitive data leaks were detected. Cookie consent is implemented, but no detailed security or incident response policies are published. The lack of vulnerability disclosure or security.txt files indicates limited transparency in security practices. Incident response contact channels are not provided, which could be a gap in readiness. Overall, the security posture is adequate for a small business but could be improved with standard security headers, DNSSEC, and published security policies.

Recommendations

  1. Enable DNSSEC to enhance domain name system security.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  4. Confirm and enforce HTTPS with HSTS to ensure secure communications.
  5. Expand privacy compliance details to include GDPR considerations and provide a terms of service page.

Technical notes

Notes

The website uses a modern JavaScript-based front-end with libraries such as jQuery, bxSlider for sliders, Magnific Popup for image galleries, and ScrollHint for UX enhancements. Google Tag Manager is used for analytics and tracking. Hosting is provided by Xserver, a common Japanese hosting provider, as inferred from nameservers. The site is mobile responsive and has good SEO meta tags and Open Graph data, though no structured data (JSON-LD) is present. Performance is moderate, with no explicit speed optimizations detected. Accessibility is basic, with some ARIA roles and alt attributes present but no advanced accessibility features. The site lacks a CMS indication, suggesting a custom or static site build. Overall, the technical implementation is solid for a small business website but could benefit from enhanced accessibility and performance optimizations.
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.
