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

ペライチは日本市場向けに特化したホームページ作成ツールを提供する中規模テクノロジー企業であり、2013年創業の安定した事業基盤を持っています。600種類以上のテンプレートと多彩な機能を備え、専門知識不要で誰でも簡単に高品質なWebサイトを作成可能です。技術的にはAWSを基盤とし、Next.jsを含むモダンな技術スタックを活用し、Google AnalyticsやMixpanelなど複数の分析ツールを導入してデータドリブンな運営を行っています。セキュリティ面ではHTTPSを完全に実装し、ドメインの移管保護も設定されていますが、DNSSEC未導入やセキュリティポリシーの公開不足が改善点です。プライバシー面ではプライバシーポリシーは整備されているものの、クッキー同意メカニズムが未実装であり、GDPR対応は限定的です。全体として高品質で信頼性の高いサービスを提供しているものの、さらなるセキュリティ強化とプライバシー対応の充実が推奨されます。

NIS2 Art. 21(2)

  1. (a) Risk analysis and security policies: Not visible from outside
  2. (b) Incident handling: One indicator
  3. (c) Business continuity, backups and crisis management: Not visible from outside
  4. (d) Supply chain security: Not visible from outside

  10. (j) Multi-factor authentication and secured communications: 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

ペライチは日本国内の中小企業や個人事業主を主なターゲットとし、簡単操作でWebサイトを作成できるSaaSモデルを展開しています。競合他社に対して豊富なテンプレートと多機能性で差別化を図り、フォーム、決済、予約、メールマガジンなどの機能を統合して顧客のWeb集客を支援。マーケティングツールや広告ネットワークとの連携も強化し、成長志向の顧客層に対応。パートナーとしてperaichiapp.comやZendeskを活用し、顧客サポートとユーザー管理を効率化しています。今後はセキュリティとプライバシー対応の強化が市場競争力向上に寄与すると考えられます。

Security posture

サイトはHTTPSを標準実装し、ドメインのclientTransferProhibitedステータスにより不正な移管を防止しています。外部スクリプトは多く導入されているものの、既知の脆弱性のあるライブラリは検出されず、フォームは存在するがセキュリティポリシーやインシデント対応情報は公開されていません。DNSSEC未設定はDNS攻撃に対するリスクを残します。プライバシー面ではクッキー同意がなく、GDPR対応は限定的。総じて堅牢な基盤を持つが、セキュリティ情報の透明性とDNSセキュリティの強化が望まれます。

Recommendations

  1. DNSSECを導入しDNSのセキュリティを強化すること。
  2. セキュリティポリシーとインシデント対応連絡先をウェブサイトに明示すること。
  3. クッキー同意バナーを実装し、GDPRなどのプライバシー規制に準拠すること。
  4. セキュリティヘッダー（CSP、HSTS、X-Frame-Optionsなど）を適切に設定すること。
  5. ユーザー向けに透明性の高いプライバシーポリシーとデータ保持方針を提供すること。

Technical notes

Notes

ペライチはNext.jsをベースにしたモダンなフロントエンド技術を使用し、AWSのDNSサービスを利用しています。Google Analytics、Mixpanel、Hotjar、Microsoft Clarityなど多様な分析ツールを導入し、ユーザー行動の詳細なトラッキングを実施。サイトは高速でモバイル最適化も優れており、SEO対策も適切に行われています。技術的負債は少なく、今後の拡張性も高いと評価されますが、セキュリティヘッダーの追加やDNSSEC導入が技術的リスク軽減に寄与します。
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.
