For many, client-side security under PCI DSS v4 has evolved into a massive operational burden. With requirements 6.4.3 and 11.6.1 mandating the authorization and integrity of every script on payment pages, security analysts are drowning in a sea of script approvals.

Jscrambler’s AI Assistant is designed to cut through this noise. Integrated directly into the Webpage Integrity (WPI) PCI DSS dashboard, it serves as an expert analyst, helping you validate the legitimacy of scripts running in payment pages, detect Magecart skimmers, and maintain PCI DSS v4 compliance with minimal effort and maximum confidence.

This guide outlines the general workflow for using the AI Assistant: Reviewing Insights, Deep-Dive Investigation, and Taking Action.

Step 1: Access AI Insights

To get started, in your dashboard, navigate to Vendor Services in the PCI DSS dropdown. Here, you will see a list of all scripts running on your payment pages. Select the “needs review” filter to see every new script, or existing script that has changed its behavior, awaiting your review.

To open up the AI insights panel, click on the vendor you would like to review, and the panel will open on the right-hand side.

Step 2: Initial Review with AI Insights & Recommendations

The Jscrambler AI Assistant performs a real-time analysis by cross-referencing detected behaviors, automated security evaluations, and known vendor purposes. The AI then determines if the script’s activity aligns with its stated function to provide tailored risk insights and recommendations.

The AI flags any newly detected behaviors, such as accessing form data ( like payment information), connecting to external domains, or creating cross-origin iframes. It then performs security checks to determine whether this is legitimate script behavior or indicative of a threat, such as a web skimmer.

• For Safe Behaviors: If the detected activity, such as network connections or iframe control, matches the known purpose of a vendor, the AI Assistant will recommend that you authorize and provide the specific permissions and actions that it should be allowed to perform.

• For Abnormal Behaviors: If the script exhibits behaviors outside its expected purpose, such as an analytics tool suddenly accessing sensitive form data or transferring information to an unauthorized domain, it is flagged as a potential skimmer, and the AI will recommend blocking these specific behaviors immediately to mitigate the threat.

Step 3: Investigate Further with the AI Chat Assistant

If the initial insights are enough for you, you can finish the review and apply the recommended permissions to the vendor. But if you need more context before making a decision, click the Analyze with AI button. 

This opens a chat interface where you can query the AI assistant directly (using pre-built suggestions, or your own unique query) to validate your assumptions or scope a threat.

Validating Assumptions

For new vendors, you can ask general questions to confirm legitimacy:

• "Tell me more about Stripe."

• "What additional risks are there with this script?"

  
  

Investigating Impact

For suspicious scripts, you can use the AI to understand the scope of an attack:

• "How many customers might have been impacted by this malicious script?" (The AI can query session data to provide exact numbers, e.g., 10,000 sessions).

• "What is the reputation of the target domains?" (The AI can identify unauthorized domains, confirming if data is being exfiltrated to a malicious URL).

Step 4: Remediation and Justification

The final stage of the workflow is taking action. The AI Assistant streamlines the compliance paperwork and technical configuration required for PCI DSS v4.

Automating Justification

When authorizing a vendor, the AI Assistant pre-populates the Justification field required for audits. It uses the insights gathered to write the note for you, ensuring consistent and accurate record-keeping. You remain in full control to edit this text or switch it off.

Applying Restrictions

When handling a threat, the Jscrambler AI Assistant can help you decide the correct granular permissions to set. 

Unlike other solutions that apply an all-or-nothing approach to blocking scripts (potentially breaking page functionality), you can follow the AI's recommendation to block specific behaviors (such as network transfers or form data access) while leaving non-malicious script behaviors active that may be necessary for the page’s operation.

Simply click Save to apply your decisions and complete the review.

Comply with Confidence

By following this workflow, you can use the Jscrambler AI to transform client-side security from a manual, error-prone task into a streamlined, data-driven process. The Jscrambler AI Assistant ensures that whether you are approving a new payment provider or mitigating an active skimmer, every decision is backed by expert intelligence.
