Backplain

What Backplain does

Backplain is a SaaS platform providing AI controls to fully support usability, trust, risk, and security management of LLM models, such as GPT-3 and GPT-4 accessed through ChatGPT, across an entire organization. It bridges between application and model, allowing users to take advantage of Generative AI safely and securely. Backplain offers a governed multi-model AI workspace, not the AI itself, but a platform that enables organizations to use every major AI model safely with data controls, audit trails, and deployment flexibility required by regulated industries. The AI Firewall is its centerpiece, ensuring data privacy and compliance. It offers flat-rate pricing and various deployment options, including dedicated bare-metal servers and customer-site deployments.

Products

• Multi-Model ChatAllows users to send one prompt to up to ten frontier models simultaneously, with responses appearing side-by-side in a single governed workspace. It supports 47 models across nine providers and includes the AI Firewall for every prompt.
• AI FirewallA patent-pending sensitive-data obfuscation system that intercepts prompts, strips sensitive data according to policy, and reconstitutes it in the response. It offers three configurable modes: Hard Block, User Warning, and Silent Reconstitute, for categories like PII, PHI, PCI, software credentials, and custom terms.
• Admin & ComplianceProvides a full audit log, SSO, SCIM, RBAC, model allowlists, and policy enforcement across the entire organization from one console. It also includes a Sandbox Mode for auditor walkthroughs.
• AgentsPre-built agents for structured research tasks, operating within the same workspace and under the same AI Firewall policy. Available agents include Search Agent and Patent Agent, with Document Review Agent and Regulatory Watch Agent in development. Custom agents can be built via Pro Services.
• Mobile App (iOS)An iOS app offering multi-model chat with camera and voice capabilities, maintaining the AI Firewall and audit log on the same tenant as the desktop seat.
• Sovereign ComputeDedicated single-tenant compute options, including BYO cloud (AWS/Azure/GCP), Backplain Private Cloud, dedicated bare metal in a SOC 2 Type II certified Tier 3 data center, or customer-site deployment for highly regulated environments.
• AI LabA physical facility in Carlsbad, California, with direct connectivity to dedicated bare-metal GPU servers in San Diego. It offers services like model fine-tuning and training on proprietary corpuses, tiger team sprints for specific workloads, and fractional ML engineer support.
• Pro ServicesOffers various professional services including implementation retainers, fractional CISO/AI Counsel, and custom agent development for Enterprise customers. Engagements are scoped, staffed, and delivered from the AI Lab.

AI approach

Backplain provides a multi-model AI workspace with a patent-pending AI Firewall for sensitive data obfuscation. It integrates with 9 major AI providers (47 models) and offers side-by-side model comparison, admin controls, agents, and mobile access. The core value is enabling safe and secure use of various LLMs by regulated organizations, ensuring data privacy and compliance without training on user data. They also offer an AI Lab for fine-tuning models on proprietary data within a controlled environment.
