## Source excerpt

Fintech is one of the most competitive and highly regulated industries in the world. Whether you're a payment processor, digital-first bank, trading platform, or wallet provider, your infrastructure is directly tied to customer trust. In this environment, outages aren't just technical incidents; a single missed transaction, delayed authorization, or moment of downtime can erode customer confidence instantly.
