Best Interactive Application Security Testing (IAST) Tools for ThreadFix

Invicti (formerly Netsparker) dramatically reduces your risk of being attacked. Automated application security testing that scales like none other. Your team's security problems grow faster than your staff. Security testing automation should be integrated into every step in your SDLC. Automate security tasks to save your team hundreds of hours every month. Identify the critical vulnerabilities and then assign them to remediation. Whether you are running an AppSec, DevOps or DevSecOps program, help security and development teams to get ahead of their workloads. It's difficult to prove that you are doing everything possible to reduce your company's risk without full visibility into your apps, vulnerabilities and remediation efforts. You can find all web assets, even those that have been forgotten or stolen. Our unique dynamic + interactive (DAST+ IAST) scanning method allows you to scan the corners of your apps in a way that other tools cannot.

HCL AppScan helps organizations embed application security across modern software development. It brings SAST, DAST, IAST, SCA, API, IaC, and Secrets security into one solution for assessing code, applications, APIs, and AI-driven workloads. Development and security teams gain centralized insight into risks, with AI-assisted analysis and agentic recommendations helping them focus on important issues and speed up fixes. AppScan works with IDEs and DevOps workflows, supports MCP-enabled environments, and combines deterministic security testing with human oversight to help organizations deliver trusted software at scale.

Invicti Web + API, previously known as Acunetix, is a DAST solution for discovering, testing, prioritizing, and managing vulnerabilities across web applications and APIs. The platform combines automated runtime scanning with AI-assisted security capabilities intended to bring automated testing closer to the depth of manual penetration testing. It can automatically discover web applications, APIs, shadow assets, unlinked pages, and undocumented endpoints across an organization's attack surface. Invicti detects more than 7,000 security issues, including OWASP Top 10, OWASP API Top 10, and business logic vulnerabilities. Testing capabilities cover single-page and JavaScript-heavy applications, LLM-powered services, authenticated user flows, multi-step application processes, and REST, GraphQL, and SOAP APIs. AI-driven risk scoring analyzes more than 200 signals, while runtime reachability, exploitability, and business context help teams determine which vulnerabilities should receive priority. Proof-based validation is designed to reduce false positives by confirming whether detected vulnerabilities are actually exploitable, with Invicti reporting 99.98% confirmation accuracy for exploitable vulnerabilities. DAST-to-SAST correlation can map vulnerabilities to source code, while AI-powered remediation provides developers with targeted guidance and automated validation retests fixes after remediation. Integrations with CI/CD, ticketing, development, and security systems help organizations incorporate continuous web and API security testing into existing software development workflows.

OpenText Dynamic Application Security Testing (DAST) offers enterprises a powerful, automated way to detect real-world security vulnerabilities by simulating live attacks against running applications, APIs, and services without requiring access to source code or staging environments. Tailored for DevSecOps teams, it efficiently prioritizes security issues to enable root cause analysis and faster remediation. The platform integrates effortlessly via REST APIs and features a user-friendly dashboard, supporting fully automated workflows within CI/CD pipelines for continuous security testing. OpenText DAST accelerates vulnerability discovery by tuning scans to the application environment, reducing false positives and surfacing critical risks earlier in the software development lifecycle. It supports modern web technologies including HTML5, JSON, AJAX, JavaScript, and HTTP2 to provide broad coverage across today’s digital applications. Automated features like macro generation and redundant page detection boost testing efficiency and reduce manual work. The solution offers flexible deployment choices, allowing organizations to operate on public or private clouds or on-premises systems. Backed by expert professional services, OpenText DAST helps businesses secure their software supply chains and maintain application integrity at scale.

Seeker® is an advanced interactive application security testing (IAST) tool that offers exceptional insights into the security status of your web applications. It detects trends in vulnerabilities relative to compliance benchmarks such as OWASP Top 10, PCI DSS, GDPR, CAPEC, and CWE/SANS Top 25. Moreover, Seeker allows security teams to monitor sensitive information, ensuring it is adequately protected and not inadvertently recorded in logs or databases without the necessary encryption. Its smooth integration with DevOps CI/CD workflows facilitates ongoing application security assessments and validations. Unlike many other IAST tools, Seeker not only uncovers security weaknesses but also confirms their potential for exploitation, equipping developers with a prioritized list of verified issues that need attention. Utilizing its patented techniques, Seeker efficiently processes a vast number of HTTP(S) requests, nearly eliminating false positives and fostering increased productivity while reducing business risks. In essence, Seeker stands out as a comprehensive solution that not only identifies but also mitigates security threats effectively.

A novel approach to security tailored to modern software development processes has emerged. By embedding security directly into the development toolchain, issues can be addressed within minutes of installation. Contrast agents actively monitor the code and provide insights from within the application, empowering developers to identify and resolve vulnerabilities without the need for specialized security personnel. This shift allows security teams to concentrate on governance and oversight. Additionally, Contrast Assess features an advanced agent that equips the application with intelligent sensors for real-time code analysis. This internal monitoring significantly reduces false positives, which often hinder both developers and security teams. By integrating seamlessly into existing software life cycles and aligning with the tools that development and operations teams currently utilize, including direct compatibility with ChatOps, ticketing platforms, and CI/CD pipelines, Contrast Assess simplifies the security process and enhances team efficiency. As a result, organizations can maintain a robust security posture while streamlining their development efforts.

Veracode provides a holistic and scalable solution to manage security risk across all your applications. Only one solution can provide visibility into the status of all types of testing, including manual penetration testing, SAST, DAST and SCA.
