NIS2 Art. 21(2)

  1. (a) Risk analysis and security policies: Not visible from outside

  3. (c) Business continuity, backups and crisis management: Not visible from outside
  4. (d) Supply chain security: Not visible from outside

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 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

    • 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

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

ペライチは日本市場における簡単ホームページ作成ツールの主要プレイヤーであり、SaaSモデルで収益を上げています。主な収益源は有料プランの提供と制作代行サービスです。ターゲットは幅広いビジネスユーザーで、特に中小企業や個人事業主に強みがあります。600以上のテンプレートと多機能なコンバージョンツールを提供し、競合との差別化を図っています。パートナーとしてperaichiapp.comやZendeskを利用し、顧客サポートとユーザー管理を強化しています。成長指標としては10年以上のドメイン運用歴と多彩なマーケティングツールの活用が挙げられます。

Security posture

セキュリティ面ではHTTPSが標準で利用されており、ドメインはclientTransferProhibitedステータスで保護されています。しかし、DNSSECが未設定であり、セキュリティヘッダー（CSP、HSTSなど）の実装が確認できません。プライバシーポリシーやクッキーポリシーの欠如はGDPRなどのコンプライアンス面でリスクとなります。インシデント対応や脆弱性開示の情報も公開されていません。これらの点は改善が必要であり、特に欧州圏のユーザーを対象とする場合はGDPR対応が急務です。

Recommendations

  1. DNSSECを有効化しDNSのセキュリティを強化すること。
  2. プライバシーポリシーとクッキーポリシーを明確に公開し、ユーザーの同意を得る仕組みを導入すること。
  3. セキュリティヘッダー（CSP、HSTS、X-Frame-Optionsなど）を適切に設定し、Webアプリケーションの防御を強化すること。
  4. 脆弱性開示ポリシーやインシデント対応連絡先を公開し、透明性と信頼性を向上させること。
  5. ユーザーデータ保護のための内部プロセスとセキュリティ文化の強化を推進すること。

Technical notes

Notes

技術的にはNext.jsを用いたモダンなフロントエンド技術を採用し、AWSのDNSを利用して安定したホスティング環境を構築しています。Google Analytics、Facebook Pixel、Mixpanel、Hotjarなど多様な分析・マーケティングツールを統合し、ユーザー行動の詳細なトラッキングを実施しています。モバイル最適化やSEO対策も良好で、ユーザー体験は高品質です。一方で、セキュリティヘッダーの欠如やプライバシー関連の情報不足は技術的負債として認識され、改善余地があります。パフォーマンスは中程度であり、さらなる最適化も可能です。
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.
