What We Don’t Like About Jscrambler
Jscrambler Web Page Integrity is a trap-based JavaScript monitoring system that relies on detecting anomalous script behavior in real time within the browser. While this is useful, it has several limitations.
Key Limitations of Jscrambler:
-
Traps can be bypassed – Jscrambler sets behavioral traps to detect script anomalies, but attackers can easily spot and evade them.
-
No real-time blocking—Unlike MIA, which can automatically restrict unauthorized scripts based on compliance policies, Jscrambler primarily alerts rather than proactively blocking threats.
-
No historical tracking – Jscrambler does not store past script versions, making forensic analysis and tracking script evolution over time impossible.
-
No AI-driven analysis – Unlike MIA, which continuously adapts to threats using AI, Jscrambler relies on manual rule-based detection, making it slower to detect new attack patterns.
-
No SSL monitoring – Jscrambler does not monitor SSL or certificate changes, potentially exposing merchants to attacks from compromised third-party sources.
More About MIA

MIA doesn’t just monitor—it proactively defends merchants by detecting unauthorized script activity and enforcing security policies in real time.

Unlike Jscrambler, MIA is designed to automate PCI compliance for SAQ A merchants by monitoring scripts, detecting unauthorized changes, and enforcing security policies. This helps businesses stay compliant without requiring additional tools or extensive manual reporting.

MIA also retains a history of script activity for compliance validation and security audits, updating AI and large language models (LLMs) in real time to continuously improve its detection mechanisms.

Additionally, MIA is included at no additional cost for Payments Guardian merchants, while Imperva requires an enterprise subscription with undisclosed pricing.
