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.
