Security Architecture & Zero Cloud Egress

Classification: Public Security Profile | Protocol: RFC-9116 / EF-SEC-2026

            Institutional Trust Posture: EstiloFlow Vantage provides private equity and venture capital underwriters with mathematically verifiable security guarantees. Diligence files never exit our isolated sovereign boundary, preventing data leakage of confidential round dynamics or cap table capitalization structures.

1. Infrastructure Sovereignty

EstiloFlow Vantage operates on private bare-metal and dedicated VPS infrastructure hosted within ISO 27001 and SOC 2 Type II certified European data centers. Every pipeline component—from optical table extractors to OCR parsers and econometric solvers—executes inside segmented Docker container networks that block unauthorized inter-service ingress.

2. Data Ingestion & Ephemeral Processing

RAM-Only Pipeline: PDF documents, spreadsheets, and pitch decks are parsed in volatile RAM. No intermediate unencrypted cache artifacts are written to persistent physical block storage.
Cryptographic Isolation: Session keys are uniquely generated per underwriting audit and discarded upon execution completion.
Zero Public Cloud Egress: Reasoning pipelines do not route customer audit data through public model APIs that train on user inputs.

3. Transport & Application Hardening

HSTS & Modern Ciphers: HTTP Strict Transport Security is enforced across all domain requests with a 1-year max-age. We disable all legacy SSL/TLS protocols, enforcing TLS 1.2 and TLS 1.3 with forward secrecy.
Content-Security-Policy: Rigid CSP rules eliminate unauthorized cross-site scripting (XSS), script injection, and cross-origin framing.
Container Sandboxing: All background inference microservices run as unprivileged non-root daemons with read-only root filesystems where applicable.
