Best of Breed

Top Notch Performance

Jscrambler is designed to effortlessly scale to support the largest and most demanding websites without causing any slowdown or disruption to the online user experience.

Key features

Third-Party Vendor Management

Advertising and social media tags, also known as pixels, can cause harm if not configured correctly or if they capture data in inappropriate areas of your website. Jscrambler provides specific tracking and management features to control the behavior of these tags across various sections of a website.

Jscrambler automatically categorizes all your marketing and advertising tags into groups (retargeting, advertising, social media, web analytics, etc.). Users can monitor and control where these categories of tags operate.

PCI DSS v4.0 Compliance

Jscrambler Webpage Integrity offers a dedicated module designed to assist online businesses in meeting the rigorous requirements of PCI DSS 4.0 concerning the use of JavaScript within payment funnels. PCI DSS 4.0 mandates that businesses maintain an inventory and guarantee the integrity of each script utilized on payment pages. Jscrambler goes beyond just meeting these requirements. The best-in-class Jscrambler module facilitates visibility, risk management, and control over all scripts. It alerts to changes to third-party tags, calling out potential data theft risks. Additionally, it provides audit-ready reports, which are crucial for maintaining seamless and secure e-commerce operations.

Polymorphic Obfuscation

Jscrambler stands out as the only obfuscation platform to provide enterprise-grade polymorphic JavaScript obfuscation. This means that each time a given script is obfuscated, the resulting code differs from all other previous outputs. This adds an extra layer of security and complexity that deters attempts by attackers to decipher the obfuscation. Polymorphic obfuscation doesn’t only alter the order of transformations applied to the code but also involves applying randomness to certain transformations. Continual alteration of the obfuscated code eliminates predictability and makes reverse engineering attempts significantly more challenging.
