Jscrambler is a technology company mainly known for its JavaScript obfuscator and eponymous monitoring framework. The obfuscator makes it harder to reverse engineer a web application's client-side code and tamper with its integrity. For real-time detection of web skimming, DOM tampering and user interface changes, the monitoring framework can be used. [1] Jscrambler's products are used in a number of sectors including finance, broadcasting and online gaming. [2] [3] [4]

History

Jscrambler started as AuditMark, which was founded in 2009 by Pedro Fortuna and Rui Ribeiro. The company's initial focus was developing a solution to fight click-fraud in advertising campaigns, since the traffic audit mechanism was JavaScript dependent. The name of the flagship product - Jscrambler - also became the name of the company, which was officially founded in 2014. [5] In September 2021, Jscrambler raised US$15 million in a series A led by Ace Capital Partners, with participation from Sonae IM and Portugal Ventures. [6]

In February 2025, Jscrambler announced the completion of a €5 million investment round led exclusively by Iberis Capital. [7] [8] The funding followed a previous €14.4 million Series A round and was intended to support the development of client-side protection technologies, particularly to address digital skimming threats and to help organizations meet the PCI DSS v4 compliance requirements ahead of the March 2025 deadline.
