The build had passed, but the logs told a different story. Deep in the trace, a critical flaw hid under layers of noise. This is where IAST self-hosted systems change the game.
Interactive Application Security Testing (IAST) runs inside your application as it executes, detecting vulnerabilities in real time. With a self-hosted IAST platform, you keep full control over your data, configuration, and deployment. Unlike cloud-only scanners, a self-hosted IAST solution lives inside your infrastructure, integrating directly with your CI/CD pipeline and staging environments.
IAST self-hosted tools analyze requests, responses, inputs, and code paths while the application runs. They combine static and dynamic testing to expose SQL injection, cross-site scripting, insecure deserialization, and other high-impact issues before they reach production. Because they operate continuously and contextually, false positives drop and remediation accelerates.
For teams in regulated industries or handling sensitive IP, self-hosting an IAST platform also solves compliance and privacy challenges. It means no dependency on a third-party cloud to run deep scans on proprietary code. It means meeting strict governance without sacrificing modern security testing workflows.
