Open banking has become a strategic priority and an IT security paradox for many financial institutions. The castles have to open their gates and lower their drawbridges, while, at the same time, finding new ways to defend against unwanted guests. In this context, many see IT security as a challenge and an inevitable evil – but nothing could be further from the truth. When done right, securing APIs can actually be the key factor to improving user experience in an ecosystem.
