Benchmarks in the README show sub-millisecond operations (e.g., 121 ns/op for IsJailed) and sub-second responses under load, making it extremely fast for real-time security checks.

It's a self-contained Go library with no reliance on external services or databases, simplifying deployment and reducing operational overhead.

Designed to run concurrently within Go applications with a tiny memory footprint, using sharding and reaping to prevent bottlenecks, as noted in the scaling section.

Allows custom rules with strike limits, expiration times, and jail sentences, plus action interfaces (WhenJailed/WhenTimeServed) for executing logic on events.
