# Best Interactive Application Security Testing (IAST) Software - Page 2 *By [Lauren Worth](https://research.g2.com/insights/author/lauren-worth)* Interactive application security testing (IAST) software inspects and analyzes an application’s code from within to discover security vulnerabilities while the application is running. This testing method differs from both [static application security testing (SAST)](https://www.g2.com/categories/static-application-security-testing-sast), which runs without actually executing an application’s code, and [dynamic application security testing (DAST)](https://www.g2.com/categories/dynamic-application-security-testing-dast), which uses a black-box testing method to perform tests from outside the application. IAST is a faster method for testing code than SAST, which can make it more desirable for teams looking to enhance their [continuous delivery](https://www.g2.com/categories/continuous-delivery) practices. However, IAST software’s real-time speed comes with a comparatively less thorough scanning technique. Unlike SAST software, which analyzes the entire codebase, IAST only executes at specific tester-defined points. IAST software notifies testers when vulnerabilities are discovered and offers remediation suggestions to help teams resolve the issue. To qualify for inclusion in the interactive application security testing (IAST) category, a product must: - Test applications as they are running - Perform predefined tests from within the application - Notify teams of vulnerabilities in real time and offer remediation suggestions ## How Many Interactive Application Security Testing (IAST) Software Products Does G2 Track? **Total Products under this Category:** 19 ### Category Stats (May 2026) - **Average Rating**: 4.48/5 - **New Reviews This Quarter**: 2 - **Buyer Segments**: Small-Business 40% │ Mid-Market 40% │ Enterprise 20% *Last updated: May 29, 2026* ## How Does G2 Rank Interactive Application Security Testing (IAST) Software Products? **Why You Can Trust G2's Software Rankings:** - 30 Analysts and Data Experts - 400+ Authentic Reviews - 19+ Products - Unbiased Rankings G2's software rankings are built on verified user reviews, rigorous moderation, and a consistent research methodology maintained by a team of analysts and data experts. Each product is measured using the same transparent criteria, with no paid placement or vendor influence. While reviews reflect real user experiences, which can be subjective, they offer valuable insight into how software performs in the hands of professionals. Together, these inputs power the G2 Score, a standardized way to compare tools within every category. ## Which Interactive Application Security Testing (IAST) Software Is Best for Your Use Case? - **Leader:** [Invicti (formerly Netsparker)](https://www.g2.com/products/invicti-formerly-netsparker/reviews) - **Highest Performer:** [Semgrep](https://www.g2.com/products/semgrep/reviews) - **Easiest to Use:** [Invicti (formerly Netsparker)](https://www.g2.com/products/invicti-formerly-netsparker/reviews) - **Top Trending:** [Semgrep](https://www.g2.com/products/semgrep/reviews) - **Best Free Software:** [Contrast Security](https://www.g2.com/products/contrast-security-contrast-security/reviews) --- **Sponsored** ### Proscan Proscan is a unified application security platform designed to help organizations streamline the management of their security tools. By integrating multiple standalone solutions into a single cohesive experience, Proscan provides comprehensive security visibility across the entire software stack. This platform replaces the complexity of managing various tools for static analysis, dynamic testing, and dependency scanning, allowing teams to focus on building secure applications without the hassle of juggling disparate systems. The platform is particularly beneficial for security teams, developers, and engineering leaders who require a consolidated view of application security risks. Proscan combines nine specialized security scanners, including Static Application Security Testing (SAST), which analyzes source code in over 30 programming languages using advanced detection methods. Dynamic Application Security Testing (DAST) further enhances security by testing live applications, identifying vulnerabilities that may only become apparent during runtime. Additionally, Software Composition Analysis (SCA) evaluates open-source dependencies across 196 package ecosystems, helping organizations detect known vulnerabilities before they can impact production environments. Proscan's capabilities extend beyond code analysis. It includes scanning for hardcoded secrets, misconfigurations in Infrastructure-as-Code, and vulnerabilities in container images. The platform also offers API security testing that validates endpoints against the OWASP API Security Top 10, ensuring robust protection for applications that leverage APIs. For organizations developing AI-powered applications, Proscan features a dedicated AI and LLM security scanner that identifies potential risks associated with prompt injections and other vulnerabilities, utilizing over 4,600 techniques mapped to the OWASP LLM Top 10. Artificial intelligence plays a crucial role in enhancing Proscan's efficiency and accuracy. The platform employs machine-learning algorithms to reduce false positives and prioritize vulnerabilities based on their potential impact. This intelligent approach allows teams to focus on the most critical security issues while providing clear explanations and actionable remediation guidance. Proscan integrates seamlessly into existing development workflows, offering IDE plugins and native CI/CD integrations that ensure security checks are part of the development process without causing disruptions. Compliance readiness is another key feature of Proscan, as it generates audit-ready reports aligned with major security standards, including OWASP Top 10, PCI DSS, HIPAA, and GDPR. This automated evidence collection simplifies the compliance process, providing organizations with the necessary documentation in various formats. Proscan is designed for security teams looking to consolidate fragmented toolchains, developers needing quick feedback, and managed security service providers managing multiple client environments, making it a versatile solution for modern application security challenges.
