Swedish ISP Sappa faced challenges related to the capacity limits of their carrier grade network address translation (CGNAT) system. Their fast growth in recent years also necessitated a need for more IPv4 addresses, which can be costly
The service provider was able to address these challenges by switching to a virtualized CGNAT
solution from NFWare that offered scalability and great technical support, and allowed Sappa to manage the cost of IPv4 addresses and grow their customer base. NFWare makes scalability cost-effective with its flexible software licensing that builds in easy license upgrades to facilitate the scalability. This means ISPs like Sappa don't have to overpay upfront for a solution that they want to grow into.
