- Encryption at rest and in transit is table stakes, not a differentiator, in fintech.
- Banking and payment partners will audit your security posture before onboarding you.
- Access control needs to be provably least-privilege, not just informally restricted.
- A documented incident response plan is often explicitly required by partners, not optional.
Encryption is the floor, not a selling point
In fintech specifically, encrypting data at rest and in transit is an assumed baseline that partners and regulators check for, not something that differentiates a company. Treating it as day-one infrastructure rather than a future roadmap item is essential.
Partners will audit you before working with you
Banking-as-a-service providers, payment processors, and other fintech infrastructure partners typically run their own security review before onboarding a new fintech company. Being unprepared for that review can delay a partnership integration by weeks or months.
Access needs to be provably least-privilege
'We're careful about who has access' isn't sufficient for fintech-level scrutiny — access control needs to be documented, reviewable, and provably restricted to only what each role genuinely needs, with a clear audit trail showing that restriction is enforced, not just assumed.
A written incident response plan is often required, not optional
Many fintech partners explicitly require evidence of a documented, tested incident response plan as part of their own due diligence. Having this ready before it's requested avoids a scramble that can stall an important partnership at a critical moment.
