Digital commerce security stands at a critical crossroads, with an average of 66 third-party vendors present during the typical e-commerce checkout flow. Each of these represents a potential security vulnerability that could compromise your customers' payment data. Few understand this landscape better than Rui Ribeiro, Co-Founder and CEO of Jscrambler.

Ribeiro's journey began in Portugal with a computer science background that led him through the banking industry before identifying a crucial gap in 2014: client-side security. What started as a broad security mission has evolved into specialized protection for payment processes, with Jscrambler now serving major e-commerce platforms across airlines, retail, and hospitality sectors.

The timing couldn't be more relevant. With the PCI Council's recent release of PCI DSS v4, client-side security has moved from a best practice to a compliance requirement. Companies must now implement strategies that protect cardholder data by securing JavaScript and payment pages while detecting unauthorized access - exactly what Jscrambler specializes in.

"Security should never be a barrier for innovation," Ribeiro emphasizes. His company's approach allows businesses to continue adding frictionless checkout features while ensuring third parties can't access sensitive payment information. This balance becomes increasingly challenging as merchants integrate chatbots, payment calculators, installment options, and other tools that improve customer experience but potentially expand the attack surface.
