VERDICT

Should I use ZAP (Zed Attack Proxy)?

Welcome to ZAP! - zaproxy.org

Worth it. ZAP is a no-brainer trial for security-savvy developers and pentesters — it is free and billed as the world's most widely used open-source web app scanner. Skip it if you need managed enterprise DAST, vendor SLAs, or hands-off scanning.

Confidence

Medium. Based on 14 public sources; many 'ZAP' search hits referred to unrelated products (Zapier, ZAP-Hosting, Zap Data Hub) and were excluded.
