The models' case: The most reliable authenticated scanner for modern SPAs — its browser-driven crawl (embedded Chromium) actually renders JS, follows client-side routing, and recorded. The models' main caveat: It's a semi-manual pentester's tool, not a hands-off CI scanner — the Enterprise edition scales it but the Pro workflow assumes an operator, and. The strongest alternative is Invicti — Best-in-class fully-automated authenticated DAST for teams — mature JS-rendering crawler, robust form/OAuth/SSO login recording with session.
