Architecture & Capabilities

約束ではなく証拠を求めるチームのために

Ownership verification

DNS TXT or HTTP token proof before any check runs.

Passive-first checks

TLS, headers, exposed services and cloud configuration.

Exploitability priority

Findings ranked using known-exploited vulnerability data.

Visual Architecture

Ownership-Verified Perimeter Discovery

Cryptographic DNS TXT and HTTP token verification ensures zero unverified scanning while continuously mapping external TLS, cloud and API attack surfaces.

Visual Architecture

Exploitability-Prioritised Remediation

Correlates perimeter exposures with active threat telemetry and known-exploited vulnerabilities across UK, EU, MENA and APAC regions.

Deterministic Technical Controls & Machine-Verifiable Evidence

OpenAPI 3.1 Contract Trust & PQC Center

1. Detection Engine (CSH Sentinel): Git-versioned Sigma rules (CSH-RULE-001..004) mapped to MITRE ATT&CK (T1110.001, T1098.003, T1048, T1190) with idempotent dedupe_key ingestion and SHA-256 immutable event hashes.
2. AI & MCP Firewall (CSH AI Guard): Pre-inference DLP scrubbing ([REDACTED_SECRET], [REDACTED_PII]), explicit per-agent Model Context Protocol (MCP) tool allowlists, and indirect prompt-injection blocking.
3. Database Isolation (PostgreSQL 16): Enforces ENABLE / FORCE ROW LEVEL SECURITY across all 20 tenant tables bound to transaction-local current_tenant_id(); cross-tenant queries fail closed with HTTP 403.
4. Human-Gated Containment: Zero autonomous destructive actions. Host isolation (isolate_host) and credential revocation require named human step-up approval recorded in an append-only audit trail.
5. Verified Exposure & GRC (CSH Scan): Cryptographic DNS TXT or HTTP ownership token required before scanning. Continuous evidence aligned with 経済産業省サイバーセキュリティ経営ガイドライン, ISMAP, 個人情報保護法 (APPI).
6. Post-Quantum Roadmap (CSH Quantum): Cryptographic inventory tracking RSA/ECDSA/TLS keys against UK NCSC 2028 discovery, 2031 priority migration (ML-KEM / ML-DSA), and 2035 full PQC completion.

よくある質問

AIが人間の承認なしに自律的に遮断操作を行うことはありますか？

ありません。検知は決定論的ルールで行われ、ARYA SAIはマスキング済み証跡から助言要約のみを生成します。すべての封じ込め操作には指名承認者の承認が必要です。

データはどこに保存されますか？

オンボーディング時にUK（ロンドン）、EU（フランクフルト）、またはEnterpriseプランのAPAC（東京）リージョンを選択できます。

ISO 27001やISMAP、経済産業省ガイドラインに対応していますか？

CSH ComplianceはISO/IEC 27001:2022、経済産業省サイバーセキュリティ経営ガイドライン、APPI、GDPR向けの技術証跡を継続的に整理します。

任意のドメインやIPアドレスをスキャンできますか？

いいえ。DNS TXTまたはHTTPトークンで所有権を証明した資産のみスキャン可能です。

マネージドサービスプロバイダー（MSP）向けの機能はありますか？

はい。委任テナント管理、ライセンスプール、パートナー課金に対応しています。
