TL;DR: Modern teams increasingly need authenticated testing, live API discovery, continuous attack surface monitoring, and audit-ready pentest evidence, according to Aikido’s comparison of Acunetix’s fit for automated DAST use cases. The broader lesson is that signature-based scanning no longer satisfies compliance or business-logic risk, so depth, not just coverage, now drives tool choice.

By the numbers:
- A 10-application portfolio in Acunetix can easily become 30-50 licensed FQDNs, because subdomains consume separate license slots regardless of shared codebase and every FQDN needs its own authentication, scan profile, and agent configuration.
Questions worth separating out
Q: What fails when teams rely on DAST instead of real pentesting?
A: DAST fails when the risk depends on workflow, state, or authorisation rather than a known signature.
Q: Why do application identity and authorisation paths matter so much in testing?
A: Because many high-impact flaws only appear when a request is made with the right role, session, or tenancy context.
Q: How do security teams know whether their testing programme is complete?
A: Look for gaps between documented endpoints and live traffic, between scanner findings and exploit validation, and between application logic and access control assumptions.
Practitioner guidance
- Separate DAST coverage from pentest evidence Use DAST for repeatable vulnerability checks, but require independent evidence for business logic, chaining, and authorization failure scenarios before treating results as compliance-ready.
- Prioritise authenticated test paths Make login-aware and role-aware test coverage a requirement for applications where permissions, tenancy, or workflow state affect access decisions.
- Inventory live APIs from traffic Compare documented endpoints with those observed in production traffic so hidden routes and shadow APIs are not left outside the testing scope.

DAST has become a coverage layer, not an assurance model. Pure scanner output still has value for known vulnerability classes, but it does not answer whether an application can be abused through legitimate workflows. That distinction matters most where authorisation, session state, and business logic determine access outcomes. Practitioners should treat scanner findings as one input, not as proof of control effectiveness.
A question worth separating out:
Q: Should organisations replace DAST with autonomous pentesting?
A: No. DAST still has value for fast, repeatable checks, but it should not be mistaken for proof of resilience. Autonomous pentesting is better suited to reasoning, chaining, and validation, while DAST remains useful for breadth. The right model is layered assurance, not a single control.
