Acunetix vs Qualys: Which is the best choice for you? [2026]

Acunetix vs Qualys: Which is the best choice for you? [2026]

If you’re evaluating Dynamic Application Security Testing (DAST) tools, you’ll inevitably encounter Acunetix and Qualys Web Application Scanning (WAS). Both platforms offer automated vulnerability detection, but they’re built for different needs, target distinct markets, and carry contrasting architectural philosophies. Acunetix focuses on deep-dive web application scanning, while Qualys WAS is part of a broader cloud platform designed for unified IT security and compliance management.

The choice between them depends on whether you prioritize a specialized scanner or a suite-based solution. But there’s a third consideration that’s reshaping how forward-thinking teams approach DAST in 2026: AI-powered penetration testing that adapts to modern application patterns without the configuration overhead, rigid licensing, or legacy architecture that both platforms carry.

This guide breaks down the practical trade-offs between Acunetix and Qualys WAS, highlights their core strengths and limitations, and explores how Beagle Security’s agentic AI-first architecture addresses the workflow friction that traditional DAST tools struggle to solve.

Acunetix vs Qualys at a glance

An alternative web & API penetration testing platform: Beagle Security

Both Acunetix and Qualys WAS are strong legacy options, but they often struggle with the pace and complexity of modern DevSecOps, especially when dealing with complex login flows (like 2FA), GraphQL APIs, and fragmented pricing models.

Beagle Security is a next-generation DAST platform built to eliminate the overhead of traditional scanners. It is an agentic AI-powered penetration testing tool that mimics real-world attacker behavior to find business-logic and context-specific flaws that are often missed by signature-based tools. With predictable, concurrent test-based pricing, it is a flexible and cost-effective alternative.

Why choose Beagle Security over Acunetix & Qualys?

• AI-enabled automation: Features AI-based login handling and business logic detection, which both Acunetix and Qualys lack.

• Flexible pricing: Uses a concurrent test-based model instead of the restrictive, escalating per-FQDN (Acunetix) or per-target (Qualys) licensing.

• Developer-first reports: Provides contextual remediation guidance tailored to the user’s tech stack, which is more actionable than the basic reporting offered by Qualys.

• Modern stack support: Offers full GraphQL support and out-of-the-box testing for 2FA-enabled applications and complex SPAs.

Acunetix vs Qualys vs Beagle Security: Feature comparison

Acunetix features

Acunetix is positioned as a comprehensive DAST solution known for its effective scanning of traditional web applications.

• IAST integration: Offers AcuSensor IAST integration for deeper insight into source code execution during DAST scans, combining black-box and white-box methods.

• Compliance ready: Provides HIPAA and PCI DSS compliance-focused reporting.

• Coverage: Excellent detection of common flaws, including the OWASP Top 10.

Acunetix weaknesses & limitations:

• Rigid licensing: The per-FQDN pricing model can become restrictive and expensive for organizations with many applications or dynamic environments (like Dev/Staging/Prod).

• Limited modern support: Struggles with intelligent crawling for complex, modern web technologies like SPAs and GraphQL.

• Authentication challenges: Multi-step or token-based authentication often requires extensive manual configuration.

Qualys WAS features

Qualys Web Application Scanning is a module within the larger Qualys Cloud Platform, making it a natural fit for organizations already using Qualys for vulnerability management.

• Integrated platform: Seamless integration with other Qualys modules for asset discovery and vulnerability management across IT assets.

• Compliance focus: Strong dashboard and policy compliance coverage, highly suitable for environments with heavy regulatory requirements.

• Broad scanning: Capable DAST engine with scan scheduling and a unified dashboard for alerts.

Qualys WAS weaknesses & limitations:

• Complex User Interface (UI): Users frequently report that the interface is outdated and unintuitive, leading to a steep learning curve.

• No AI or business logic: Lacks AI-driven features for advanced logic detection or automated login handling.

• Limited DevSecOps: Offers only limited CI/CD integration and requires manual tuning and configuration to avoid false positives.

Beagle security features

Beagle Security is a next-generation DAST platform built natively for cloud-first, API-heavy architectures. Its agentic AI engine adapts attack strategies based on the specific technology stack it encounters, eliminating the manual configuration overhead that traditional scanners demand.

• Agentic AI penetration testing engine: Adaptive attack logic that automatically adjusts testing techniques based on your application’s behavior and stack.

Acunetix vs Qualys vs Beagle Security: Pricing comparison

*Acunetix pricing according to AWS Marketplace

Acunetix pricing

Acunetix targets mid-market businesses with pricing starting at around $7,000/year per FQDN. The per-domain model creates particular challenges for complex applications; multi-domain setups require separate targets for each subdomain, multiplying licensing costs well beyond initial estimates. The absence of a traditional free trial means teams must engage sales before properly assessing platform fit.

Qualys WAS pricing

Qualys WAS operates on a per-target licensing model with custom quote pricing, making it difficult to estimate costs upfront. For organizations already using the Qualys Cloud Platform, the integration value may justify the spend. For teams seeking a standalone DAST solution, the opaque pricing and per-target model can make budget planning unpredictable as application portfolios grow.

Beagle Security pricing

Beagle Security offers clear, usage-based pricing without arbitrary restrictions on domains or targets. Self-serve plans start at $1,188/year, with enterprise plans starting at $8,500/year for 5 concurrent tests. Teams can add or remove applications at any time and split monthly test quotas across multiple applications, a model that benefits organizations with fluctuating testing needs or diverse application portfolios. A 14-day free trial includes access to all Advanced plan features with one complete penetration test, letting teams evaluate agentic AI-powered testing capabilities before committing.

Which is best for you?

While Acunetix and Qualys serve established security programs well, they carry the baggage of legacy licensing and architecture.
