AI governance principles

Plexus AI enhances legal workflows while maintaining the highest standards of privacy and security:

  • Secure AI integration

    We use OpenAI’s enterprise-grade GPT models. Your data is never used to train public AI models.

  • Tenant-Isolated Storage

    Conversations and document context are stored in isolated databases and vector stores, ensuring zero data crossover between tenants.

  • Strict Data Controls

    Customer data stays within your secure environment to support your use case only, never shared or repurposed.

  • Encryption & Access Controls

    All AI operations meet AES-256 and TLS 1.2+ standards with full audit logging.

  • Training Protocols

    Plexus AI learns only from your uploaded legal playbooks and policies, not public internet data.
