How automated retesting is changing the way we fix vulnerabilities

In vulnerability management, fixing a flaw is just the beginning. Verifying that it’s truly resolved can take days—or even weeks—when done manually. That’s where automated retesting steps in.

Automated retesting is a powerful feature within Strike’s pentesting services that’s reshaping how security teams close the loop on vulnerability remediation. By using AI to replicate the original attack steps and confirm whether a vulnerability still exists, this solution helps companies validate fixes in seconds, not days.

Keep reading to learn how automated retesting works and why it’s becoming essential for modern pentesting programs.

What is automated retesting and why does it matter?

Automated retesting replicates the steps a hacker used to exploit a vulnerability, then replays them to confirm whether the issue has been properly fixed. This process removes the need for security engineers to manually rerun every test, saving hours of work.

Here’s why this matters for your security team:

• Instant feedback: As soon as a patch is deployed, Strike’s system can verify its effectiveness. You’ll know immediately whether a fix worked—or if it needs to be adjusted.
• Lower risk, faster: Every moment a vulnerability remains unvalidated is a moment of risk. With automated retesting, you can reduce your exposure and strengthen your security posture rapidly.
• No added costs: Unlike traditional retests, automated retesting is included at no extra cost—even as we expand the range of supported vulnerability types.
  

By integrating automated retesting into your pentest workflow, you reduce friction, increase clarity, and make remediation measurable.

How automated retesting works

Strike’s automated retesting uses AI to reproduce the exact exploitation path of a real hacker during a pentest. The system logs how the vulnerability was discovered and exploited, then uses that blueprint to confirm whether it can still be triggered after remediation.

Here’s how it works step-by-step:

1. During the pentest, our team or platform identifies a vulnerability and records every action used to exploit it.
2. After you apply a fix, you can request an automated retest with a single click in the Strike Platform.
3. Our system replays the original exploit path, checking if the vulnerability still behaves the same way or has been neutralized.
4. You get instant results, showing whether the remediation was successful or if further action is needed.

It’s efficient, accurate, and repeatable—perfect for security teams working under tight timelines.

Key benefits of automated retesting

Whether you’re managing dozens of vulnerabilities or trying to keep up with compliance audits, automated retesting adds clarity and speed to the entire remediation cycle.

Here’s what your team gains:

• Faster vulnerability resolution
  No more waiting days for manual retests—get results in minutes and move forward with confidence.
  
• Better resource allocation
  Your engineers can focus on actual remediation work, rather than chasing retest tickets or scheduling follow-ups.
• Improved risk management
  By shortening the validation window, you reduce your attack surface and respond to threats more proactively.
  Seamless pentesting workflows
  With just one click to retest, teams can validate fixes without back-and-forth emails or manual intervention.
  

Strike’s automated retesting empowers security teams to work smarter—not harder—when closing the loop on vulnerability management.

In manual workflows, retesting a vulnerability involves:

• Reaching out to the pentest provider
• Scheduling a new session
• Re-executing the exploit manually
• Waiting for updated reports

This process can take days and often introduces delays between remediation and validation. Worse, these gaps can lead to a false sense of security—assuming a fix worked without confirmation.

Automated retesting eliminates that uncertainty. It brings the verification process closer to real-time, aligning with the speed modern security demands.
