A Cybersecurity Playbook for Resilient Banking Modernization

Modern information technology risk in banking rarely lives inside a single application. It lives in the relationships between systems: legacy platforms, identities, APIs, vendors, data flows, manual processes, and recovery procedures.

The Devsu approach to resilient modernization

See the whole system, not just the pieces

Core platforms, identities, APIs, vendors, and manual processes are usually secured separately. Risk concentrates in the connections between them — not inside any one system.

Move faster when it matters most

Mapped dependencies mean faster incident scoping, confident answers for examiners aligned with the Cyber Risk Institute's Profile and clean recovery of one service instead of a whole environment.

Modernize in bounded, reversible steps

Sequenced change keeps the blast radius small and gives security and audit teams a checkpoint after every step not just at the end of the project.
