Architecture & Capabilities

Para equipas que precisam de provas, não de promessas

Agent & MCP registry

Inventory every agent, model, owner and MCP server in one place.

Tool allowlists

Define exactly which tools each agent may call, per environment.

Prompt-injection defence

Detect indirect injection in user input and retrieved content.

Secret & PII redaction

API keys, tokens and personal data are removed before inference.

Human approval

Writes, payments and shell commands are routed for step-up approval.

Decision log

Every allow, block and approval is recorded with its rationale.

Visual Architecture

Pre-Inference MCP & Agent Firewall

Inspects every Model Context Protocol (MCP) tool invocation, enforcing per-environment allowlists and blocking indirect prompt-injection payloads before execution.

Visual Architecture

DLP Secret Scrubbing & Audit Ledger

Automatically redacts bearer tokens, API keys and personal data before model inference and writes every allow/block decision to an append-only ledger.

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 CNCS Quadro Nacional de Referência para a Cibersegurança, Diretiva NIS2, RGPD / LGPD.
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.

Defense-in-Depth Isolation

Database-enforced tenant boundaries & UK NCSC PQC alignment.

PostgreSQL 16 FORCE ROW LEVEL SECURITY on all 20 tenant tables.
Pre-inference DLP secret and PII scrubbing before any advisory call reaches ARYA SAI.
Aligned with UK NCSC 2028 / 2031 / 2035 Post-Quantum Cryptography milestones.

Perguntas frequentes

A IA executa ações sozinha?

Não. A deteção baseia-se em regras determinísticas e cada ação de contenção exige aprovação humana.

Onde ficam guardados os dados?

Escolhe entre UE (Frankfurt) ou Reino Unido (Londres) na ativação.

Apoiam a conformidade NIS2, CNCS e ISO 27001?

Sim, o CSH Compliance recolhe evidências técnicas contínuas para ISO/IEC 27001, NIS2 e RGPD.

Podemos analisar qualquer domínio?

Apenas ativos cuja propriedade tenha sido validada por DNS TXT ou token HTTP.

Trabalham com MSPs?

Sim, com gestão delegada de clientes e licenciamento partilhado.
