Retester Agent
Your validation specialist that confirms vulnerabilities are fixed and prevents regression.
What is Retester Agent?
The Retester Agent specializes in validating that security fixes actually work. It automatically retests previously discovered vulnerabilities to confirm remediation, prevents regression, and ensures security improvements persist across code changes.
Problems It Solves
Fixes Don't Actually Work
Developers mark vulnerabilities as "fixed" but the fixes are incomplete, bypassed, or don't address the root cause. You think you're secure but vulnerabilities remain exploitable.
Regression Vulnerabilities
Code changes reintroduce previously fixed vulnerabilities. Without retesting, you don't know that old security issues have returned.
No Fix Validation
Security teams don't have time to manually retest every fix. Developers self-attest that issues are resolved without independent validation.
Partial Remediation
Developers fix the specific instance flagged by scanners but miss identical vulnerabilities elsewhere in the codebase.
How Retester Agent Works
Automated Retest Execution
Automatically retests previously discovered vulnerabilities after developers claim fixes. Validates that issues are actually resolved.
Fix Verification
Attempts to exploit fixed vulnerabilities using original attack vectors. Confirms exploits no longer work and root causes are addressed.
Regression Testing
Continuously retests all previously fixed vulnerabilities on every code change. Immediately detects if security issues are reintroduced.
Fix Quality Assessment
Analyzes fixes to determine if they address root causes or just symptoms. Identifies incomplete or superficial remediation.
User Benefits
Verify Fixes Work
Know with certainty that vulnerabilities are actually fixed, not just marked as resolved in issue trackers.
Prevent Regression
Catch reintroduced vulnerabilities immediately. Stop old security issues from returning in new code.
Faster Remediation
Developers get immediate feedback on fix quality. No more back-and-forth with security teams about whether fixes are complete.
Compliance Evidence
Demonstrate to auditors that vulnerabilities were properly remediated and verified. Maintain proof of fix validation.
Security Debt Reduction
Ensure vulnerability remediation actually reduces security debt rather than just closing tickets.
Quality Improvement
Developers learn what constitutes a proper fix vs. incomplete remediation. Security quality improves over time.
Real-World Use Cases
Incomplete SQL Injection Fix
Developer fixed one SQL injection but used same vulnerable pattern in 12 other queries. Retester found all instances and prevented partial fix.
Regression Detection
Code refactor reintroduced XSS vulnerability fixed 3 months prior. Automated retesting caught regression within hours of commit.
Fix Bypass Discovery
Authentication bypass was "fixed" with client-side validation. Retester demonstrated server-side bypass still worked, prompting proper fix.
