How secure is online business banking?

First Internet Bank protects your business with layers of advanced digital security, including multifactor authentication, real‑time transaction monitoring and support from a dedicated team of U.S.-based fraud specialists if anything looks unusual.

As a bank that has operated exclusively online since day one, digital security isn’t an add‑on, it’s foundational. Every sign in, transfer and transaction is protected using the same enterprise‑grade safeguards trusted by leading financial institutions, along with access to knowledgeable, real people when you need help.
