Fix All Vulnerabilities: What PCI DSS 4.0 Really Means for Application & API Security

PCI DSS 4.0 isn’t just another compliance update—it’s a mandate to rethink how you approach application and API security.

Requirement 11.3.1.1 now explicitly states that you must manage all vulnerabilities, not just critical or high-risk ones. That’s a massive shift for AppSec and DevOps teams already buried in backlogs.

Manual triage won’t scale. Annual pen tests won’t help. And most tools won’t tell you what to fix—or how to fix it.

This is why we built Aptori’s AI Security Engineer:
To help you fix everything—fast, continuously, and with context.

“PCI DSS 4.0 isn’t just a compliance update—it’s a signal to the industry that fixing vulnerabilities is now the standard, not the exception.”— Sumeet Singh, CEO of Aptori

What’s Changed with PCI DSS 4.0

Requirement 11.3.1.1: All vulnerabilities must be managed.
That means every finding—no matter the severity—must be:

• Remediated
• Mitigated
• Or formally accepted

And you need to be able to prove it.

This applies across apps, APIs, and client-side code. If your system handles payment data, it's in scope. You can’t afford to miss something exploitable—even if it’s “low risk” on paper.

‍

Why Most Teams Won’t Keep Up

Traditional AppSec tooling wasn’t built for this:

• Scanners generate too much noise. You waste time chasing irrelevant findings.
• Manual triage is a bottleneck. Every new release creates a new backlog.
• Fixes take too long. Developers get vague tickets with no context.
• Compliance is now continuous. You need to show you're fixing issues as they happen—not months later.

How Aptori Helps

Aptori is your AI Security Engineer—a purpose-built system that finds and fixes real vulnerabilities in real time.

“The only way to manage and remediate all vulnerabilities at the scale today’s software demands is with AI. That’s why we built Aptori.”— Sumeet Singh, CEO of Aptori

Context-Aware Testing

We don’t just match signatures.
Aptori understands your applications, APIs, and business logic—so it can:

• Detect broken object-level access, injection risks, insecure client-side scripts, and more
• Understand the structure and intent of your code
• Find issues static analysis tools and WAFs miss

Continuous Coverage

Security can’t be a once-a-quarter thing anymore.
Aptori integrates into:

• CI/CD pipelines to catch issues before release
• Staging and production to detect runtime risks
• Dev workflows so developers see issues early—with context

Automated Fixes

Aptori doesn’t just report issues—it fixes them.

• Maps each vulnerability to its root cause
• Provides secure code suggestions right where your team works (IDE, PR, CLI)
• Tracks and verifies whether vulnerabilities are resolved

It’s like having a security expert reviewing every change—but it works at machine speed.

Built-In Compliance Reporting

PCI DSS 4.0 is already in effect. You’ll need evidence.

Aptori generates what you need:

• Vulnerability lifecycle tracking
• Fix timelines and verification
• Reports that align with:
  • Requirement 6.5 – Secure development practices
  • Requirement 11.3.1.1 – Full vulnerability management
  • Client-side controls for browser data protection

“We’re not replacing security engineers. We’re giving them an AI teammate that never sleeps, never slows down, and always prioritizes real risk.”— Sumeet Singh, CEO of Aptori

Don’t Just Pass the Audit—Prevent the Breach

Compliance isn’t the goal. Security is.
But if your process can’t handle fixing every vulnerability, you’ll fall behind—fast.

“Security isn’t a one-time event. It’s a continuous process—and PCI DSS 4.0 makes that official. Aptori helps you stay compliant every day, not just on audit day.”— Sumeet Singh, CEO of Aptori
