Don’t Let Compliance Kill Conversions—Secure Your Client-Side

PCI DSS 4.0 isn’t just another compliance update—it’s a wake-up call.
PCI DSS 4.0 isn’t just another compliance update—it’s a wake-up call.

The threat landscape continues to evolve, and businesses handling payment data are already being targeted by increasingly sophisticated attacks. If your defenses aren’t keeping up, you’re not just facing compliance gaps—you’re putting customer trust, brand reputation, and revenue at risk.

Third-Party Scripts
Could Put Your Customer Data at Risk

If your marketing team relies on Google Tag Manager (GTM), third-party scripts, tracking pixels, or complex JavaScript setups, PCI DSS 4.0 introduces new security challenges that you can’t afford to ignore.
From analytics tools to retargeting pixels, marketing teams rely on dozens of third-party scripts to optimize campaigns. But attackers are increasingly exploiting JavaScript vulnerabilities and supply chain weaknesses to skim payment data—without triggering traditional security alerts.

Formjacking & Magecart Attacks

Cybercriminals inject malicious code into your checkout page, silently stealing credit card details.

Unmonitored GTM Containers

Complex GTM setups make it easy to deploy scripts but hard to detect unauthorized or risky changes.

Compromised Third-Party Vendors

A vulnerable ad script or tracking pixel could expose sensitive customer data—and you wouldn’t even know it.

Why This Matters to You

Evolving Threats Demand Immediate Action

Cybercriminals are more sophisticated than ever, and traditional security measures aren’t enough.
Attacks targeting third-party scripts, client-side vulnerabilities, and supply chain dependencies have become  the go-to method for stealing payment data.
PCI DSS 4.0 introduces new expectations for proactive risk management and continuous security monitoring—making it clear that compliance is no longer just a checklist. Spider C/Security helps you remain compliant with new standards and keep your client data safe and secure.

Non-Compliance Hits More Than IT

If your scripts or GTM containers aren’t properly secured under PCI DSS 4.0’s new requirements, the fallout isn’t just a security team headache—it’s a direct threat to marketing performance and customer experience:
Loss of tracking & analytics – If security teams start blocking third-party scripts due to compliance risks, you might lose critical marketing data.
Drop in conversions – Security-conscious customers won’t complete purchases if they sense your checkout page isn’t secure.
Stricter platform regulations – Ad platforms like Google and Meta are prioritizing security and privacy compliance. A non-compliant site could impact ad approvals and campaign performance.
Revenue & reputation damage – A data breach can lead to fines, lost customers, and negative PR, wiping out months of hard-earned growth.

How PCI DSS 4.0 Changes the Way You
Manage Scripts & GTM

JavaScript Auditing & Script Integrity Monitoring

Businesses must now actively track and control what scripts are running on their site, ensuring that unauthorized or modified JavaScript isn’t putting customer data at risk.

Secure Google Tag Manager Deployments

GTM is a powerful tool, but it can also introduce security blind spots. Under PCI DSS 4.0, businesses must document, review, and restrict how scripts are injected via GTM to prevent security breaches.

Continuous Security Monitoring

No more one-time security reviews. PCI DSS 4.0 requires real-time tracking of script behavior, meaning marketers must work alongside security teams to ensure compliance without breaking critical campaign tracking.

Raising the Bar on Security

PCI DSS 4.0 expands old standards  to address new risks, particularly client-side security, continuous risk management, and enhanced authentication requirements.
The compliance landscape is shifting, and businesses that wait until the last minute will struggle to catch up. Don’t wait, start protecting your clients data today with Spider C/Sec.
