AI Governance for Law Firms Without Exposing Client Confidentiality
Let legal teams use AI for research, drafting, contract review, and matter analysis without sending privileged client information to external models. WalledAI detects and masks sensitive legal data before it reaches any LLM, then creates an audit trail for legal, compliance, and security teams.

Protect Attorney-Client Privilege Across Every AI Workflow
Legal teams need more than a generic AI policy. They need controls that prevent client, matter, and work-product information from reaching AI models without authorization.
WalledAI replaces sensitive legal information with secure tokens before an AI model processes the request. Authorized users receive the relevant context on return, while the model never sees the original confidential data. You can mask privileged legal data before it reaches an LLM across every approved assistant.
AI Governance for Law Firms and Client Confidentiality
WalledAI helps law firms use AI for research, drafting, contract review, and matter analysis without exposing confidential client data. Sensitive legal information is masked before prompts reach a model, while policy decisions, user context, and audit evidence are logged for legal, security, and compliance teams.
Use AI Across Legal Workflows Without Losing Control
AI-Assisted Legal Research
Allow lawyers to summarize case law, analyze research notes, and prepare arguments while protecting client and matter references.
Contract Review and Redlining
Mask party names, financial terms, confidential clauses, and deal details before contracts are sent to AI for analysis.
Legal Drafting and Summarization
Apply policies to briefs, memos, discovery material, and internal communications before legal teams use AI to draft or summarize content.
Matter and Knowledge Search
Give legal teams safe access to internal knowledge and matter information with policy-based controls and complete interaction logging.
Outside Counsel and Client Workflows
Create controls for sensitive client work, approved AI tools, and role-specific access across internal and external legal teams.
Example: Safe AI-Assisted Contract Review
Before WalledAI
"Review this agreement for indemnity risk. The buyer is Northstar Health, the contract value is $8.4 million, and the counterparty requested these confidentiality exceptions..."
Client identity, deal value, and confidential negotiation terms are exposed to the AI provider.
With WalledAI
"Review this agreement for indemnity risk. The buyer is [Organization_1], the contract value is [Amount_1], and the counterparty requested these confidentiality exceptions..."
WalledAI preserves the structure the AI needs for analysis while keeping confidential legal data outside the model.
Legal AI Governance Built Around Your Policies
AI tool visibility
See approved and unapproved AI tools in use across practice groups.
Policy enforcement
Apply controls before prompts reach any AI model, not after the fact.
Role-based access
Distinct permissions for partners, associates, paralegals, legal operations, and compliance.
Matter risk profiles
Tune sensitivity by matter type and practice group.
Ethical walls
Restricted-access policies keep deal and litigation teams separated.
Immutable audit trails
A tamper-evident record of every governed AI interaction.
Cross-tool monitoring
Consistent governance across ChatGPT, Claude, Copilot, and internal AI.
Sovereign deployment
On-premises, private-cloud, and air-gapped options.
Acceptable-use, confidentiality, records-management, and information-security policies can be converted into enforceable AI controls, so the rules the firm already publishes are applied at the moment a prompt is sent. Pair them with role-based legal AI access controls and a responsible AI governance framework to keep adoption consistent across practice groups.
Defensible Legal AI Audit Trails and Compliance Evidence
Know which AI tools are in use, what policy controls applied, what sensitive data was protected, and how each interaction was governed.
Complete interaction lineage
Prompt, policy decision, masking result, and response linked to one record.
Policy enforcement records
Which rule applied, what it blocked or masked, and who was involved.
Detection and masking logs
Categories of sensitive legal data found and the tokens substituted.
Role and access history
Changes to permissions, ethical walls, and matter-level access over time.
Evidence packages
Exportable sets for internal audits, client security reviews, and board reporting.
WalledAI helps legal and security teams document how AI use is governed. It does not replace legal advice or determine privilege. Reporting is delivered through legal AI audit trails and governance reporting, and maps to the security and compliance controls your clients ask about in security reviews.
Built for the Teams Responsible for Legal AI Risk
General Counsel
Set a defensible legal AI governance posture and report risk to leadership.
Legal Operations
Enable adoption across practice groups while applying consistent policies and controls.
CISO and Security Teams
Monitor AI exposure, prevent sensitive-data leakage, and investigate policy events.
Compliance and Privacy Teams
Access audit-ready evidence and map controls to organizational requirements.

Legal AI Governance FAQs
How can law firms use AI without exposing confidential client information?
Firms need controls at the point of use, not only a written policy. AI governance for law firms works by detecting client names, matter references, financial terms and work product inside a prompt, replacing them with secure tokens before the request leaves the firm, and logging what was detected and which policy applied. Lawyers keep the analysis they need; the model never receives the underlying confidential text.
Can WalledAI protect attorney-client privileged data when lawyers use ChatGPT or Claude?
WalledAI sits between your users and the model, so prompts sent to ChatGPT, Claude, Copilot or an internal model are inspected and masked first. That keeps privileged and confidential content out of the provider's systems and produces a record of the controls applied. WalledAI supports your confidentiality practices; it does not determine privilege or guarantee a legal outcome.
Can legal teams use AI for contract review while protecting confidential terms?
Yes. Party names, contract values, pricing, confidential clauses and negotiation positions can be tokenised before a contract or clause set is sent for analysis. The model still sees the structure and language it needs to assess indemnity, liability or termination risk, and authorised reviewers see the restored values on return.
Does WalledAI create audit trails for AI-assisted legal work?
Every interaction is recorded with its user, role, tool, applied policy, detection results and masking actions. Legal, compliance and security teams can export evidence packages for internal audits, client security reviews and board reporting, and reconstruct exactly how a given AI-assisted task was governed.
Can WalledAI support ethical walls and role-based access for legal teams?
Yes. Access can be scoped by role, practice group and matter, so deal teams, litigation teams and support staff only reach the AI capabilities and data appropriate to their work. Restricted-matter and ethical-wall policies are enforced at request time and reflected in the audit log.
Which AI tools can WalledAI govern for law firms and legal departments?
WalledAI governs commercial assistants such as ChatGPT, Claude and Copilot, API access to major model providers, and internal or open-source models deployed inside the firm. Policies are applied consistently across those tools so governance does not depend on which assistant a lawyer chooses.
Can WalledAI be deployed on-premises or in a private cloud?
Yes. WalledAI runs on-premises, in your private cloud, or in an air-gapped environment, so confidential matter data and audit records stay within the firm's own boundary and jurisdiction. Client data is never used to train models.
