LangSmart provides an on‑premise AI firewall and control plane that centralizes access to multiple large language model providers while enforcing granular, identity‑aware policies and compliance guardrails such as HIPAA, GDPR, SOX, and the EU AI Act. The platform authenticates each request via the enterprise IdP, logs full audit trails, applies real‑time content filtering, and uses a four‑phase BERT semantic cache with sub‑5 ms overhead to reduce latency and costs. All components run as Rust‑based services in the customer’s data center or private cloud, eliminating third‑party data exposure and supply‑chain risk.

Problem
Enterprises using large language models face supply‑chain attacks, credential leakage, and lack of visibility into AI usage, making it difficult to meet regulatory requirements such as HIPAA, GDPR, SOX, and the EU AI Act.
Solution
LangSmart delivers an on‑premise AI firewall and control plane that centralizes access to multiple LLM providers while enforcing granular policies, cost controls, and compliance guardrails. The platform authenticates every request against the organization’s identity provider, logs full audit trails, and applies real‑time content filtering and usage quotas. A four‑phase BERT‑based semantic cache reduces latency and provider costs, and intelligent routing distributes traffic across active models according to configurable ratios. All components run as Rust‑based services in the customer’s data center or private cloud, eliminating third‑party data exposure and PyPI supply‑chain risk.
Target Audience
Primary customers are regulated enterprises—CIOs, CISOs, and IT security teams—that require secure, auditable, and cost‑controlled access to generative AI across multiple providers.
Features
- On‑premise deployment with no external cloud dependencies, protecting against supply‑chain compromises
- Identity‑aware governance integrated with Entra ID, LDAP, SAML, OIDC for per‑user audit trails
- Inline policy engine that enforces content filters, rate limits, budget caps, and regulatory rules (HIPAA, GDPR, SOX, EU AI Act)
- 4‑phase BERT semantic cache delivering 55‑75 % hit rates and sub‑5 ms overhead
- Intelligent multi‑model routing (e.g., 70 % GPT‑4, 30 % Claude‑3.5) with configurable ratios
- Virtual keys that abstract provider credentials; keys are revocable and rotatable without application changes
- Complete audit log and compliance reporting with exportable traces tied to virtual keys
- Rust‑based proxy and MCP governance layer for low latency and high‑throughput production workloads
