# Composal vs OWASP ZAP

By Composal. Sources reviewed: 2026-10-15.

ZAP probes web application security properties. Composal checks product requirements and user-visible behavior in browser journeys. Composal is not a security scanner and does not replace ZAP.

## Composal

Composal sends AI browser agents to use your running web app and check the outcomes you care about. Define journeys as plain-English Scenarios, map existing flows with Discovery, or explore for bugs with Deep Scan. Runs keep recordings and reproduction steps so your team or coding agent can investigate a Finding.

## OWASP ZAP

Dynamic web application security testing

OWASP ZAP is an open-source web application security scanner and proxy. It supports automated and manual security testing workflows, including crawling and active scanning of applications.

## Where each fits

Choose ZAP when authorized dynamic security testing is required. Choose Composal for functional browser QA and reproducible product Findings. A release process can run both with distinct security and product criteria.

## Try this evaluation

Use an isolated authorized test environment. Run a scoped ZAP scan and a Composal journey for the same feature; compare security alerts with functional outcomes, then keep their triage criteria separate.

### Coverage

Which user outcomes must this release prove, and which specialist checks must stay in your existing stack?

### Setup

Who prepares accounts, test data, permissions and access to the deployment being tested?

### Evidence

Can the engineer reproduce a reported failure from the recording and steps, without asking the tester to investigate again?

### Ownership

Who updates the checks when the product changes, and can the team review what a passing result actually proves?
