| Impart Security | Impart is the unified runtime protection platform that helps security teams stop AI, API, and web application attacks in production - at scale, with confidence. We built Impart because runtime protection shouldn't be a choice between visibility and enforcement. While traditional WAFs became opaque black boxes and API security tools offeredonly detection without action, we knew there had to be a better way. Drawing from our next-gen WAF heritage, we created a platform where security teams can actually block attacks safely in production, moving at the speed of modern threats.What We Do Our Runtime Application Protection Platform unifies WAF, API Security, Cloud Application Detection & Response (CADR), and AI Runtime Protection into a single solution. Powered by WebAssembly (WASM) technology and AI-native workflows, Impart enables security teams to design, test, and deploy custom security rules with unprecedented speed and safety. We enforce at the ingress layer—the critical point of entry for every attack chain—delivering sub-10ms latency even at Super Bowl-scale traffic loads. Our platform is built for modern cloud environments, deploying as a Kubernetes-native sidecar that scales horizontally with your workloads.Why Impart Security teams choose Impart because we give them what they need most: the ability to block attacks safely in production without breaking their applications. Our WASM-powered rules are programmable, testable, and manageable through GitOps workflows, making us the only solution that both security and engineering teams trust.From detecting account takeover and business logic abuse to protecting against prompt injection and AI-specific threats, Impart consolidates point solutions into one platform that actually enforces protection where it matters most. | $1.7M | Pre-Seed | Dec 20, 2021 |  |
