Zen runs inside the application itself and watches what it does as it runs. When it sees a dangerous action, it blocks it before harm is done.

## What it is

Zen is an in-app firewall embedded directly in the application. It observes calls the application makes at runtime, such as database queries and system commands. When a request looks like an attack, it stops it on the spot.

## Key capabilities

- Runs embedded inside the application at runtime.
- Blocks SQL injection attempts.
- Blocks command injection attempts.
- Stops dangerous actions before they execute.

## Who it's for

It suits teams that want a layer of protection inside the running application. It helps developers guard against injection attacks without rewriting everything. It fits web apps and services that handle untrusted input.
