Site-to-site IPsec VPN
An encrypted tunnel between the firm’s edge firewall and the data centre firewall.
LegalApp follows the life of a legal matter, from opening a client file through document ingestion, research, drafting, professional review, and eventual retention or deletion. It is hosted on infrastructure dedicated to each firm.
Each client container has its own document store, search index, encryption key, access list and audit log. Matters for that client are organised inside it. The design aims to stop searches and AI answers from crossing client boundaries. The AI draws on the client container the lawyer has open. There is no shared search index across clients.
The access gateway checks user roles and matter-team membership before permitting access. Application services and the AI model are shared within the firm’s environment, and the design states that they retain no client documents between requests. Views, queries and exports are logged. At the end of the agreed retention period, the proposed process deletes the container and its encryption key together.
These controls are a basis for a confidentiality and governance discussion. Their effectiveness would need to be validated during implementation, including backups, legal holds, retention exceptions, and access between different matter teams inside the same client container.
The application is intended to be reached through HTTPS over VPN, without direct exposure to the public internet.
