Security & Governance
Enterprise security architecture and governed execution built specifically for UK law firms and confidential legal operations.
1. Security Overview
At ANZA Services LLP (“ANZA”), we recognize that law firms handle their clients’ most confidential, sensitive, and commercially critical information. With over two decades of experience supporting UK law firms, security and governance are the foundation of our technology and operating model.
Our proprietary orchestration engine, the Zizi platform, was engineered from day one to enforce rigorous governance, deterministic rules, and complete auditability across all automated and AI-enabled workflows.
2. The Zizi Trust Layer: Governed Execution
Traditional AI tools operate as opaque “black boxes” with the risk of hallucinations and unmonitored drift. Zizi serves as a deterministically governed trust layer between your case management systems and legal execution:
Lawyers and qualified fee-earners retain final control and sign-off on all substantive drafting, decisions, and matter outcomes.
Every task is validated against the law firm’s approved playbooks, clause libraries, and standard operating procedures before progression.
Every workflow event, document extraction, model interaction, and fee-earner approval is logged with timestamped, non-repudiable audit logs.
Bounded execution environments ensure AI components operate strictly within defined procedural guardrails with automated fallbacks.
3. Encryption & Tenant Segregation
- Encryption in Transit: All data transmitted to and from ANZA services is secured using TLS 1.3 (with TLS 1.2 minimum fallback) with modern cipher suites and HSTS enabled.
- Encryption at Rest: All stored data, case files, databases, and operational telemetry are encrypted using AES-256 bit encryption with managed key rotation.
- Logical & Data Isolation: Each law firm operates within logically separated partitions. Precedents, matter data, and workflow logs are never commingled across clients.
4. AI Confidentiality & Zero Data Retention
We maintain zero-data-retention (ZDR) enterprise agreements with our AI infrastructure partners. Your firm’s inputs, drafts, case facts, and proprietary precedents are never used to train or refine public AI models.
Prompt data is ephemeral and discarded immediately following completion of the specific workflow request.
5. Cloud Infrastructure & Operational Security
Our digital systems are hosted on enterprise cloud infrastructure in the Microsoft Azure UK South region, meeting ISO 27001, SOC 1, SOC 2, and Cyber Essentials alignment.
