Porto’s cybersecurity firm Jscrambler raises $15 million

Porto-based web and mobile application cybersecurity firm Jscambler has raised $15 million in a Series A funding round. Focusing primarily on, as the name might imply, JavaScript protection and client-side web and mobile real-time security monitoring, the startup intends to use the new funds to beef up sales and marketing efforts in the EU and US markets as well as push forward the product roadmap.

Founded in 2014, Jscrambler has come into its own over the course of 2021 with supply chain cyber-attacks reaching an all time high, the SolarWinds attack being a prime example. This act alone called for US President Biden to issue an executive order calling on all government agencies to shore up its supply chain security.

At present, browser native defenses and traditional security mechanisms have been studied and thwarted by attackers, who are now addressing client-side (i.e., everything that takes place on the browser or end-user device) of things, at an alarming success rate.

And this is exactly where Jscrambler steps into the spotlight. With a suite of client-side protection options for the e-commerce, finance, software and IT, media and OTT, gaming and gambling, and healthcare industries, Jscambler is trusted by businesses ranging from SMEs to Fortune 500 companies.

"We are at a critical turning point in web security. This year’s streak of high-profile software supply chain attacks has put everyone on guard against the massive damages inflicted when attackers breach critical applications of private and public organizations,” commented co-founder and CEO Rui Ribeiro. “We anticipated this trend years ago and are successfully delivering differentiated technology and expertise to solve client-side attacks.”

Jscrambler’s $15 million Series A round was led by Ace Capital Partners and saw the participation of existing investors including Portugal Ventures.

“There is a clear, growing need for disruptive web technology and we are extremely impressed with Jscrambler’s solution and its successful adoption with top-tier enterprise customers across multiple verticals,” comments Ace’s Augustin Blanchard. “We strongly believe that this new investment by Ace Capital Partners will fuel this growth, enabling the world’s biggest enterprises to find in Jscrambler, a promising and already established European leader in its market, the answer to all their challenges in terms of client-side security and application shielding.”
