Impart Security markets itself as AI runtime defense and moved its website from impart.security to impart.ai, yet its strongest outside endorsements still name the earlier business: the analyst firm Latio gave it a Best API Security award, and its AWS Marketplace listing sells a product named WAF and API Security Platform. The product is one inline enforcement engine that inspects web, API, LLM, and AI-agent traffic and blocks attacks in production instead of only alerting. FanDuel's chief information security officer vouches for it on the company's site. Madrona led a 12 million dollar Series A in June 2025. The newer MCP and agent modules have no named customer in the public record, while a Crossbeam CISO testimonial credits the LLM module alongside web and API protection.
| Description | Runtime protection platform that enforces security policy inline across web applications, APIs, LLM traffic, MCP tools, and AI agents, using AI-generated rules and virtual patches to block attacks in production. | [f1] |
|---|---|---|
| Founded | 2021 | [f2] |
| HQ | San Francisco, California, United States | [f2] |
| Latest funding | Series A, $12M | [f3] |
| Product | What it does |
|---|---|
| Impart API Security | Applies inline, sequence-aware enforcement to every API call, detecting and blocking shadow APIs, schema violations, and sensitive-data exposure at runtime. |
| Impart WAF | Web application firewall that lets security teams design, test, and deploy virtual patches for zero-day and agentic attacks in minutes. |
| Impart LLM Protection | Runtime enforcement for LLM traffic that stops prompt injection, data exfiltration, and agent misuse before execution. |
| Impart MCP Protection | Maintains a live catalog of MCP servers and tools and enforces inline policy on caller, scope, and arguments before tool invocation. |
| Impart Agent Protection | Evaluates AI agent behavior across full action sequences and blocks patterns such as privilege escalation and data exfiltration before actions execute. |
| Impart Runtime Defense Agents | Patching, detection, reporting, and red-team AI agents that operate on the shared enforcement engine to write, test, and deploy runtime protections. |
