Could you build this?
No Building an enterprise runtime security SDK with sub-millisecond local bot detection, real-time prompt injection heuristics, and distributed low-latency policy engines demands deep cybersecurity and systems engineering expertise.
What it would actually take: Arcjet uses WebAssembly running in-process inside V8/Node/Next.js runtimes communicating with a distributed edge network (Anycast, Fly.io, or Cloudflare Workers) running token-bucket rate limiters and machine learning classifiers for prompt injection. Developing this requires specialized threat intelligence, IP reputation data pipelines, and low-level Rust/Wasm compilation to ensure near-zero overhead on user requests.
