Jscrambler, a Porto, Portugal-based client-side protection company, raised $5.2M in funding.
The round was subscribed exclusively by Iberis Capital. This latest investment followed a previous $15M Series A funding round led by Ace Capital Partners with participation from Sonae IM and Portugal Ventures, which also led the company’s initial Seed round.
The company intends to use the funds to expand operations and its development efforts.
