Stronger Together: A Defense-in-Depth Strategy with IAST and Waratek RASP

Editor’s Note: This is the third in a series of posts on the advantages of a Shift Left – Shield Right approach to security.

Security is about layers. A single point of failure is a recipe for disaster. By combining the pre-production intelligence of IAST with the production protection of Waratek RASP, you create a seamless, powerful, and modern defense-in-depth strategy for your applications.

This isn’t about buying redundant tools; it’s about creating a synergistic lifecycle of security.

The Workflow:

1. Develop & Test (IAST): Developers write code. During QA and integration testing, the IAST agent identifies vulnerabilities with high accuracy and provides line-of-code feedback. The most critical flaws are fixed immediately, before they ever reach production.
2. Deploy & Protect (RASP): The application is deployed to production with the Waratek RASP agent. RASP now acts as the ultimate safety net, providing active protection for:

• • Accepted Risks: Low-priority vulnerabilities found by IAST that were deferred.
  • Unknown Threats: Zero-day vulnerabilities that have yet to be discovered.

Use Cases in Action

• Use Case: Rush to Launch

• • Problem: Launch day for a new app is rapidly approaching and the Dev team cannot fix all of the low level vulnerabilities identified by IAST in time. Do you delay the app’s launch or do you allow the app to go into production under the protection of Waratek RASP?
  • Solution:

1. 1. 1. Waratek RASP monitors for anomalous behavior and known attack patterns in real-time, automatically blocking any deviation from the normal execution of code. Any attempt to exploit the known vulnerabilities identified by IAST will be blocked.
      2. Waratek RASP can also apply a virtual patch in the runtime instantly, without any downtime and without source code changes, further rendering any vulnerability safe until a binary patch can be applied as part of a regular patch cadence.

• Use Case: The Zero-Day Panic

• • Problem: A vulnerability like Log4j is announced. You have hundreds of applications, and you don’t know which ones are vulnerable or how to patch them all immediately.
  • Solution:

1. 1. 1. Waratek RASP is already protecting you. Its rule-based engine blocks the remote code execution technique used by the exploit, meaning your entire application estate was protected before you even knew the threat existed.
      2. You use your IAST tool across your test environments to quickly and accurately identify every single application and library that contains the vulnerable code, providing your teams with a precise, actionable list for patching.

This combined approach of Waratek IAST + Waratek RASP (Secure) covers your entire application lifecycle, from the first line of code to the last second it runs in production. In the next post in this series, we’ll discuss how this duo stands up to the next generation of threats: AI-driven attacks.

Waratek IAST will be available in late Q1. Contact [email protected] for details.
