Tetrate provides AI governance infrastructure and service mesh solutions built on open-source technologies like Istio and Envoy. The company's primary offering is Agent Router Enterprise, which delivers managed LLM and MCP gateways with AI guardrails for enterprises adopting generative AI applications. Their platform enables organizations to implement governance, risk management, and cost controls for AI deployments through comprehensive monitoring, policy enforcement, and compliance frameworks. Tetrate's AI governance capabilities include risk management features such as secure access controls, data protection, and compliance reporting for regulations like GDPR, HIPAA, and SOX. The platform provides cost governance through real-time monitoring, budget controls, automatic fallback to cost-effective models, and cross-provider optimization. It captures GenAI API calls passively without requiring application changes, allowing organizations to discover and manage AI usage, analyze trends, set budgets, and enforce guardrails. The company also offers Tetrate Istio Distro (TID), a vetted upstream distribution of Istio with FIPS-certified builds for FedRAMP environments, and Tetrate Service Bridge (TSB), an edge-to-workload application connectivity platform. These products provide service mesh capabilities including traffic management, security controls, distributed tracing, and metrics collection. Tetrate's solutions integrate with enterprise systems through SSO, LDAP, and other authentication mechanisms, targeting large enterprises that require enterprise-grade support and SLAs.
