As web applications grow more complex and API-driven, the need for robust, real-time security testing has never been greater. Dynamic Application Security Testing (DAST) tools simulate real-world attacks on running applications, uncovering vulnerabilities that static analysis often misses. In 2025, the DAST landscape is defined by AI-enhanced scanning, CI/CD integration, and deep API coverage. Here's a look at the top DAST platforms leading the charge.
Invicti – The DAST-First Powerhouse
Why it stands out: Invicti delivers a DAST-first AppSec platform built for enterprise-scale automation. Its proof-based scanning confirms exploitability with 99.98% accuracy, drastically reducing false positives. With native support for REST, SOAP, GraphQL, and gRPC APIs, Invicti is ideal for modern architectures.
- Predictive risk scoring
- 50+ CI/CD integrations
- Role-based access control
- Optional SAST/SCA modules via Mend.io
- AI-powered vulnerability prioritization
Best for: Large enterprises, compliance-heavy environments, and CI/CD workflows.
Fortinet + Lacework FortiCNAPP – Unified Cloud-Native DAST
Why it stands out: Fortinet's DAST capabilities are now deeply integrated with Lacework FortiCNAPP, following Fortinet's strategic acquisition of Lacework. This integration brings together Fortinet's threat intelligence and Lacework's cloud-native application protection platform (CNAPP), delivering full-stack security from code to cloud.
- FortiDAST: Automated black-box testing using FortiGuard Labs' threat research, advanced fuzzers, and crawlers to detect OWASP Top 10 vulnerabilities and runtime misconfigurations.
- FortiCNAPP Integration: Agentless scanning across hybrid and multi-cloud environments, including support for Windows workloads and real-time AWS CloudTrail alerting.
- CI/CD Coverage: Seamless integration with FortiDevSec and major CI/CD tools for end-to-end lifecycle testing.
- Fleet Management: Visibility into agent inventory and deployment health across large environments.
- Security Graph Explorer: Visualizes attack paths and asset relationships for faster investigation and remediation.
Deployment Highlights:
- Uses Terraform and Lacework CLI for automated setup.
- Supports Azure agentless workload scanning with NAT gateway options to reduce public IP overhead.
- Requires specific Azure permissions and quotas for optimal performance.
Best for: Enterprises seeking unified cloud-native security with deep visibility, automated scanning, and simplified operations across AWS, Azure, and GCP.

Final Thoughts: Why DAST-First Matters
A DAST-first approach ensures that security teams focus on exploitable vulnerabilities, not just theoretical risks. By simulating real-world attacks, DAST tools provide actionable insights, reduce false positives, and integrate seamlessly into modern development pipelines.
Whether you're a large enterprise or an SMB, choosing the right DAST tool means balancing accuracy, integration, and scalability. The platforms above represent the best of 2025 — each with unique strengths tailored to different organisational needs.
