Best Interactive Application Security Testing (IAST) Tools for Startups

Compare the Top Interactive Application Security Testing (IAST) Tools for Startups as of October 2026

What are Interactive Application Security Testing (IAST) Tools for Startups?

Interactive Application Security Testing (IAST) tools are advanced security solutions that detect vulnerabilities in software by analyzing applications in real-time while they are running. They integrate seamlessly into the development and testing environments, offering precise, context-aware insights by observing application behavior, code execution, and data flow. Unlike traditional security tools, IAST combines the strengths of Static Application Security Testing (SAST) and Dynamic Application Security Testing (DAST), enabling it to identify both code-level and runtime vulnerabilities. These tools are ideal for modern DevSecOps practices, as they provide actionable results quickly, allowing developers to address issues early in the development lifecycle. By delivering high accuracy and reducing false positives, IAST tools enhance the overall security posture of web and mobile applications.

    Invicti Security

    Application security is noisy and overly complicated. The good news: you can relieve that unnecessary noise and dramatically reduce your risk of attacks with Invicti. Keeping up with security is more manageable with accurate, automated testing that scales as your needs shift and grow. That's where Invicti shines. With a leading dynamic application security testing solution (DAST), Invicti helps teams automate security tasks and save hundreds of hours each month by identifying the vulnerabilities that really matter. Combining dynamic with interactive testing (DAST + IAST) and software composition analysis (SCA), Invicti scans every corner of an app to find what other tools miss. With asset discovery, it's easier to discover all web assets — even ones that are lost, forgotten, or created by rogue departments. Through tried-and-true methods, Invicti helps DevSecOps teams get ahead of their workloads to hit critical deadlines, improve processes, and communicate more effectively.

    Invicti Web + API

    Invicti Security

    Invicti Web + API, formerly Acunetix, is a dynamic application security testing (DAST) platform for identifying and validating vulnerabilities across web applications, APIs, and other runtime assets. The platform automatically discovers applications, APIs, shadow assets, unlinked pages, and undocumented endpoints while supporting modern JavaScript applications and authenticated workflows. Its scanning engine detects more than 7,000 types of security issues, including vulnerabilities covered by the OWASP Top 10 and OWASP API Top 10 as well as business logic flaws. Invicti combines AI-driven risk scoring with runtime reachability, exploitability, and business context to help security teams prioritize vulnerabilities that represent demonstrable risk.
