Jscrambler

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. Jscrambler's products are used in a number of sectors including finance, broadcasting and online gaming.

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. 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.

In February 2025, Jscrambler announced the completion of a ₮5 million investment round led exclusively by Iberis Capital. 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.
