28 Best DAST Tools (2026)
I tested 28 DAST tools — free (ZAP, Nuclei, Nikto) to enterprise (Invicti, Burp Suite). Features, pricing, and CI/CD integration compared.
- I tested 28 active DAST tools hands-on — 5 free (ZAP, Nuclei, Dastardly, Wapiti, Nikto), 3 freemium (Burp Suite, Bright Security), and 20 commercial — the largest DAST comparison available.
- The global DAST market reached $3.61B in 2025 and is projected to grow to $8.63B by 2031 at 15.59% CAGR (Mordor Intelligence, 2026-2031). HCL AppScan, Invicti, and Veracode are the 2025 Gartner Leaders.
- ZAP joined Checkmarx (September 2024) — still free and open-source under Apache v2. Nuclei has 12,000+ community-maintained templates for targeted vulnerability checks.
- For CI/CD pipelines, Dastardly (free, 10-min cap), ZAP, Nuclei, and StackHawk work well for quick PR scans. Full crawl scans typically take 1-8 hours and are best scheduled nightly.
- Invicti's proof-based scanning automatically confirms exploitability to reduce false positives. Acunetix + Netsparker merged into Invicti; Synopsys DAST became Black Duck Web Scanner.
What is DAST?
DAST is a black-box security testing method that crawls and attacks a running web application from the outside, simulating real attacker behavior to find runtime vulnerabilities without requiring access to source code.
Unlike SAST tools that analyze your code statically, DAST tests the application as it actually executes.
That makes it language-independent and able to catch misconfigurations, authentication flaws, and injection bugs that static analysis will never see.
The global DAST market hit $3.61 billion in 2025 and is projected to reach $8.63 billion by 2031 at a 15.59% CAGR, according to Mordor Intelligence (2026-2031 forecast).
The trade-off is clear: DAST cannot tell you the exact file and line number where the bug lives. It tells you what is broken, not where in the code to fix it.
Scans are slower too — a full crawl typically takes 1-8 hours — and the scanner may miss pages it cannot reach through normal navigation.
That is why most teams run SAST and DAST together. For CI/CD, Dastardly (free, 10-min cap), ZAP, Nuclei, and StackHawk all work well for quick PR scans. Full crawl scans are better off running nightly.

What Are the Major DAST Market Changes?
The DAST vendor landscape has gone through heavy consolidation since 2022, with multiple acquisitions, mergers, and rebrandings reshaping the market. If you are comparing tools and run into unfamiliar names, this list covers every major change:
- ZAP joined Checkmarx (September 2024) — ZAP is now “ZAP by Checkmarx” with all three project leaders on the Checkmarx payroll. Still free, still Apache v2 licensed.
- Veracode bought Crashtest Security (2022) — Folded into the Veracode platform. Veracode earned a Gartner Leader spot in 2025.
- HCL AppScan 360° v2.0 shipped — HCL AppScan unified platform with AI-assisted testing and FIPS 140-3 compliance. Also a Gartner Leader in 2025.
- Acunetix + Netsparker merged into Invicti — Invicti is the enterprise platform; Acunetix continues as the standalone product.
- Synopsys Web Scanner became Black Duck Web Scanner — Synopsys sold its Software Integrity Group in 2024. It now operates as Black Duck Software.
- Fortify WebInspect moved to OpenText — OpenText bought Micro Focus in 2023, which had bought HP Enterprise Software (including Fortify) back in 2017.
- Snyk bought Probely (November 2024) — Probely’s DAST engine now powers Snyk API & Web, which launched April 2025.
- Sentinel Dynamic / WhiteHat Security rebranded — Synopsys acquired WhiteHat in 2022. The product is now called Black Duck Continuous Dynamic.
How to Choose a DAST Tool
Choosing the right DAST tool comes down to three factors: the type of application you are testing, your budget, and whether you need automated CI/CD scanning or hands-on pentesting capability. Here is what I would focus on:
- What are you scanning? A traditional multi-page web app is easy for any DAST tool. SPAs, mobile backends, and API-heavy apps are harder. You need a tool that can render JavaScript and parse API specs. Escape focuses on API and business logic testing. Invicti and Burp Suite handle complex web apps well.
- Manual or automated? If you are doing hands-on pentesting, Burp Suite is the industry standard (ask any pentester). For automated CI/CD scanning, look at ZAP, Nuclei, StackHawk, or Dastardly.
- Do you need API support? If your app has REST or GraphQL endpoints, check that the tool can import OpenAPI specs and actually test those endpoints. Escape, StackHawk, and Tenable WAS do this well.
- How noisy is it? False positives kill adoption. Invicti uses proof-based scanning to confirm exploitability automatically. Detectify uses crowdsourced vulnerability research. On the open-source side, Nuclei templates are precise because each one targets a specific vulnerability.
- What is your budget? ZAP, Nuclei, Dastardly, Wapiti, and Nikto are free. Burp Suite Community is free for manual use. StackHawk has a 14-day trial. Everything else needs a paid license.
- How many apps? If you are scanning hundreds of targets, you need enterprise tools like Invicti, Veracode, or HCL AppScan with proper multi-target management.
