Introducing APIs to service an increasingly mobile customer base adds significant value to your business, but also adds new risks from a growing number of mobile security threats. Only your authorized mobile apps, running in untampered environments and communicating over secured channels, can access your APIs and backend services. Botnets, fraudulent transactions, malicious scripts, and fake apps are blocked at the source. Mobile has transformed how customers do banking and make financial transactions. Explosive growth in mobile requires fresh and easily introduced security solutions.
