Rasp gRPC: Built-in Runtime Protection for High-Performance gRPC Services

Smoke poured from the build server. Logs scrolled faster than eyes could follow. The gRPC service had just gone live, and every millisecond mattered. You reach for Rasp gRPC because you need speed without sacrificing safety.

Rasp gRPC is a runtime application self-protection layer built directly into your gRPC stack. It intercepts calls between clients and services, inspects payloads, and enforces security rules before dangerous code runs. It doesn’t rely on external agents or network filters. The protection lives inside the application process, watching every request.

With Rasp gRPC, incoming data is decoded in the context of the protobuf definitions. The system checks for SQL injection, command injection, and deserialization attacks. It analyzes headers and metadata for anomalies. Since it operates inside the gRPC server, it sees the exact function being invoked, along with the arguments. This allows precise blocking without breaking normal service behavior.

Performance stays tight. Rasp gRPC uses async, non-blocking inspection to avoid latency spikes. Security checks run inline with gRPC middleware chains. Overhead is minimal because there’s no heavy data marshaling between layers. You keep the throughput you built for, while gaining deep visibility into runtime activity.

Deploying Rasp gRPC is straightforward. Integrate a small library into your gRPC service code. Configure rules with YAML or JSON. Push to your staging environment. Test against real client calls. When ready, roll to production. No reverse proxies. No changes to your client-side code.

Rasp gRPC fits modern microservice environments. It supports Go, Java, Python, and more via language-specific gRPC hooks. It scales horizontally by replicating the protected service across nodes. Logs feed directly to your observability stack for correlation with metrics and traces.

If your architecture depends on gRPC, runtime protection is not optional. Attacks target the exact surface gRPC exposes: serialized data over HTTP/2, clear method names, structured payloads. Without a guard inside the process, you are trusting every byte that crosses the wire.

Put Rasp gRPC in place. See every call. Stop every exploit before it runs. Build it into your next deploy or add it now. Test it with hoop.dev and see it live in minutes.
