PCI DSS 4.0.1 requires organizations to protect payment environments from application vulnerabilities and client-side script risks.
Imperva and Feroot PaymentGuard AI handle these from different angles. Imperva offers an application security platform with WAF, API security, bot management, and client-side protection as part of one system.
Feroot specializes in client-side security, with fast deployment and the flexibility to work alongside whatever application security tools you already use.
Imperva: Application security platform with client-side protection
Imperva‘s Application Security Platform protects multiple layers of your web environment. The platform includes a WAF for blocking attacks, API security for finding and protecting APIs, bot management to stop automated threats, runtime protection (RASP), and Client-Side Protection for monitoring browser scripts. Everything connects through one dashboard.
What Imperva does well:
- PCI-certified WAF that blocks web application attacks with low false positives
- API security that discovers shadow APIs and prevents data leakage
- Bot management to stop credential stuffing and automated fraud
- RASP technology that neutralizes attacks during code execution
- Client-Side Protection for PCI DSS Requirements 6.4.3 and 11.6.1
- PCI Dashboard showing compliance status with exportable reports
- Uses Content Security Policy (CSP) headers to enforce client-side rules
Imperva works best for organizations that want application security managed through one platform. Client-Side Protection is included as part of the broader Imperva system.

FAQ
Does Imperva monitor client-side scripts for PCI compliance?
Yes. Imperva’s Client-Side Protection handles Requirements 6.4.3 and 11.6.1 as part of their Application Security Platform. It’s designed for customers already using Imperva. Organizations pick Feroot when they need standalone client-side security that works with any infrastructure, or when they want faster deployment without a platform requirement.
How is deployment different?
Feroot deploys in 24 hours with a JavaScript tag. No infrastructure changes. Works with whatever you have. Imperva Client-Side Protection works best if you’re already on their platform. For new customers, there’s platform setup involved. Organizations without Imperva often go with Feroot for speed.
Which is better for audits?
Both cover 6.4.3 and 11.6.1. Feroot creates pre-formatted reports that QSAs expect, with all the script inventory, justifications, and change logs already organized. Imperva gives you a PCI Dashboard with exportable reports through their platform. Teams with tight audit deadlines often pick Feroot because the reports are ready to hand over.
How Feroot and Imperva Work Together
Some organizations use Imperva for application security (WAF, API protection, bot management) and add Feroot for specialized client-side monitoring. This gives them platform benefits for application layers and specialist tools for browser security.
Example: A retail company runs Imperva WAF and API security but needs client-side compliance. Instead of switching their entire application security stack, they add Feroot in 24 hours. Imperva handles application threats. Feroot handles browser scripts. Both feed into their SIEM.
Another example: An enterprise wants unified application security operations. They use Imperva’s full platform for WAF, API, bots, and client-side protection across all properties. One vendor, one interface, one support contract.
The choice depends on whether you want platform simplicity or specialist depth.
Summary
Imperva offers application security through one platform: WAF, API security, bot management, and client-side protection together. Feroot specializes in client-side security with 24-hour deployment and the flexibility to work with any infrastructure.
Pick Imperva when you want full application security from one platform. Pick Feroot when you need fast client-side compliance that works with whatever tools you already have.
