# Vulnerability Verification for Blackbox Assessments Now Available

We've added Vulnerability Verification to Takumi blackbox assessments.
This feature lets you verify whether a vulnerability detected in a past assessment has actually been fixed.

## Overview

Vulnerability Verification re-runs the original attack scenario for a specific vulnerability.
Run it after deploying your fix to confirm that the remediation works as intended.

Dispatch it from the **"Verify Vulnerability"** button on an application assessment report, then select the vulnerability you want to verify.

The result is shown as **Not Vulnerable** or **Vulnerable**, along with the reasoning behind the verdict.

Vulnerability Verification is available to all Takumi byGMO users with blackbox assessment access.
