Best Interactive Application Security Testing (IAST) Tools with a Free Trial of 2026

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.

Hdiv solutions provide comprehensive, all-encompassing security measures that safeguard applications from within while facilitating easy implementation across diverse environments. By removing the necessity for teams to possess specialized security knowledge, Hdiv automates the self-protection process, significantly lowering operational expenses. This innovative approach ensures that applications are protected right from the development phase, addressing the fundamental sources of risk, and continues to offer security once the applications are live. Hdiv's seamless and lightweight system requires no additional hardware, functioning effectively with the standard hardware allocated to your applications. As a result, Hdiv adapts to the scaling needs of your applications, eliminating the conventional extra costs associated with security hardware. Furthermore, Hdiv identifies security vulnerabilities in the source code prior to exploitation, utilizing a runtime dataflow technique that pinpoints the exact file and line number of any detected issues, thereby enhancing overall application security even further. This proactive method not only fortifies applications but also streamlines the development process as teams can focus on building features instead of worrying about potential security flaws.

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.

S4 enables Salesforce DevSecOps to be established in the CI/CD pipeline within less than an hour. S4 empowers developers with the ability to identify and fix vulnerabilities before they reach production, which could lead to data breaches. Secure Salesforce during development reduces risk, and speeds up deployment. Our patented SaaS Security scanner™, S4 for Salesforce™, automatically assesses Salesforce's security posture. It uses its full-spectrum continuous app security testing (CAST), platform that was specifically designed to detect Salesforce vulnerabilities. Interactive Runtime Testing, Software Composition Analysis and Cloud Security Configuration Review. Our static application security testing engine (SAST) is a core feature in S4. It automates scanning and analysis for custom source code within Salesforce Orgs including Apex, VisualForce and Lightning Web Components and related-JavaScript.
