Best DAST tools

Beagle Security

Beagle Security provides continuous, agentic AI pentesting that behaves more like a penetration tester than a signature scanner. It’s built for real-world complexity: multi-step logins, single-page apps, GraphQL APIs, and brittle flows that often trip automated scanners. Beagle Security’s core advantage is signal quality, i.e. less noise, more context, and reports that slot neatly into engineering workflows.

Beagle Security prioritizes “time to clear risk.” It reduces false positives, maps findings to business impact, and integrates with CI/CD so teams can block risky releases, retest on fix, and show progress to leadership. For organizations consolidating security tooling, it also becomes a pragmatic “source of truth” for application exposure across web apps and APIs.

Beagle Security key features:

• AI-driven automated penetration testing

• Advanced support for web apps, APIs, and GraphQL

• Continuous testing integrated into CI/CD pipelines

• Compliance-ready reporting (OWASP, HIPAA, PCI DSS)

• Smart vulnerability prioritization to reduce noise

Beagle Security pricing

Beagle Security offers flexible pricing, with plans for growing startups as well as enterprise-grade deployments. Tiered pricing ensures scalability without hidden costs.

• Essential plan: $1,188/year (2 tests per month)

• Advanced plan: $4,308/year

• Enterprise plans: Custom quote

Ratings & reviews

G2 rating: 4.7/5 (87 reviews)

On G2, Beagle Security is praised for ease of integration and accuracy of results. Teams highlight the platform’s ability to catch vulnerabilities automatically before deployment.

ZAP by Checkmarx

Zed Attack Proxy (ZAP) remains the most accessible entry point to DAST. It’s open source, widely documented, and backed by a committed community.

For smaller teams, internal security champions, or budget-constrained programs, ZAP enables meaningful testing without procurement friction. With scripting and add-ons, advanced users can extend it significantly.

That said, ZAP typically requires more hands-on effort to scale and to maintain parity with enterprise workflows. If you already have seasoned AppSec engineers and want fine-grained control, ZAP is a strong building block. If you need turnkey reporting, compliance mapping, and enterprise support, you’ll want to pair ZAP with internal processes. Or look to a commercial DAST.

ZAP by Checkmarx key features:

• Open-source and free to use

• Active and passive scanning capabilities

• Extensible with community add-ons

ZAP by Checkmarx pricing

Free and open-source.

G2 rating: 4.7/5 from 12 reviews.

Strong community support but limited enterprise reviews.

Burp Suite

Burp Suite is the standard toolkit for many penetration testers. The Professional edition excels for exploratory testing, where human expertise matters; the Enterprise edition adds scheduled and automated scans for continuous coverage.

If you have in-house penetration testing capabilities and want to combine manual depth with repeatable automation, Burp fits well.

Operationally, the learning curve can be steeper for non-specialists, and translating raw findings into developer-ready remediation plans may require an internal playbook. Still, for teams that value hands-on control and deep manual verification, Burp Suite is a proven choice.

Burp Suite key features:

• Manual and automated testing support

• Powerful interception proxy

• Enterprise Edition enables large-scale automation

Burp Suite pricing

Burp Suite pricing in 2026 is structured into three editions, each tailored to different audiences.

• Community edition: Free

• Professional edition: $475 per user per year

• Enterprise Edition (DAST): Custom pricing

Pricing typically starts from $6,040 per year and can reach $34,900 annually, depending on the configuration.

Key factors to consider when choosing an AppSec tool

Choosing the right AppSec tool depends on your business needs. Here are the factors decision-makers should evaluate:

1. Specific use case: Pre-production testing (SAST, SCA, DAST) or runtime protection (RASP)?

2. Integration: Can the tool integrate seamlessly with your CI/CD pipelines, ticketing systems, and existing workflows?

3. Scalability: Will the tool support your growing application portfolio?

4. Ease of use: Is it developer-friendly, or does it require security specialists to operate?

5. Reports and analytics: Does it provide actionable insights tailored for both developers and executives?

6. Support: Is enterprise-grade support available when issues arise?

7. Budget: Does the pricing align with your security investment strategy?

8. Deployment options: Does it support cloud, hybrid, or on-premises environments?

Final thoughts

The landscape of AppSec tools in 2026 reflects the growing complexity of securing applications in a fast-moving digital world. From SAST and SCA that catch vulnerabilities early, to DAST and RASP tools that provide deeper coverage and runtime protection, no single category is enough on its own.

However, for most organizations looking for a comprehensive and scalable AppSec strategy, Beagle Security stands out as the best overall choice. By combining AI-driven DAST capabilities, developer-friendly workflows, and compliance-ready reports, it bridges the gap between security and innovation.

For decision-makers, the key takeaway is clear: Invest in tools that not only secure your applications but also align with your organizational culture, developer workflows, and long-term growth strategy.
