Top IAST tools examined


Invicti AppSec emphasizes its “ZeroNoise” approach, aiming to minimize false positives through machine learning and expert-curated rules. It offers comprehensive security testing capabilities, encompassing both static and dynamic analysis as an automated test runner.

Invicti in action

Invicti, formerly known as Netsparker IAST, consolidates with existing workflows and addresses critical security areas like the OWASP Top 10 and compliance standards. 2 This combination of features and a wide range of programming languages, both web and server-side language compliance, makes Invicti a compelling solution for organizations seeking to elevate their application security analysis without sacrificing development efficiency.

Security focus:

Invicti’s primary focus is providing comprehensive application security, covering various aspects:

  • OWASP Top 10: Identifies and mitigates vulnerabilities listed in the OWASP Top 10, a well-known list of critical web application security risks.
  • Compliance standards: Helps meet compliance requirements for regulations like PCI DSS, HIPAA, and GDPR.
  • API security: Secures APIs alongside web applications for holistic security coverage.

Point to consider

  • Invicti and Acunetix, both web application security offerings by Invicti Security, diverge in their target audiences and functionalities. While both utilize advanced vulnerability scanning technology with automated verification, Invicti caters to larger enterprises, emphasizing integration and automation. Conversely, Acunetix targets smaller organizations preferring a more hands-on approach to security.

IAST: Real-time vulnerability monitoring in the development process

IAST empowers developers by shifting security testing left in the SDLC, identifies vulnerabilities during the test/QA stage, and reduces remediation costs and delays. This aims to put developers in control and allows for continuous security testing throughout the software development life cycle by integrating with CI/CD pipelines.

Unlike other application testing tools, IAST provides immediate vulnerability reports after code changes, enabling developers to identify and fix vulnerabilities earlier in development. This integration, ease of use, and scalability make IAST a preferable option for web application development teams and DevOps environments to monitor vulnerabilities in the development cycle.

Offerings and limitations of IAST tools

Interactive application security testing (IAST) combines static analysis of source code with dynamic application security testing (DAST) techniques to perform penetration testing. Such comprehensive application security solutions are tailored for web application attacks in continuous testing environments.

Ideal For

-Complex applications with extensive and diverse codebases.
-Early-stage development and continuous integration environments

-Web applications, APIs, and services.
-Final stages of development, pre-release, and post-deployment security assessments

-Early vulnerability detection.
-Lower false positive rate

-False positives and negatives.
-Detecting runtime and environment specific issues.
-Identifying issues in third-party libraries and components

-Vulnerabilities that are detectable at runtime.
-Requires a fully functional and deployed application.
-Static code issues and deeply embedded vulnerabilities

-Initial setup and configuration


  • Insights: IAST tools can identify real-time insights, enable early vulnerability detection (during testing/QA) and can detect up to 30% more vulnerabilities than traditional SAST methods, according to a 2024 Gartner study. 7
  • False positivity reduction: By leveraging application logic and context Interactive Application Security Testing (IAST) provides accurate results with low false positives (compared to DAST and SAST). Most IAST tools’ automated testing capabilities generate up to 70% reduction, observed in a 2023 Forrester report. 8


  • Monitoring: One downside of IAST tools is that they are limited to identifying the vulnerabilities in the functional testing environment; they can not monitor security issues in areas of missing code coverage.
  • Customizability: An important consideration is to maintain the balance between pre-configured rules and human tester control since the selected tool might have limitations in customizability.

How to complement IAST tools?

IAST tools can be complemented with DAST tools or SAST tools. For those starting their application security journey or working at SMEs, these can also be good starting points:
