[FinTech & Payments]
FinTechs face PCI-DSS, PSD2, and investor due diligence on timelines that don't allow for slow security programmes. TechSonar embeds senior security engineers to build continuous compliance, secure payment flows, and satisfy card schemes and regulators, without slowing your product velocity.

The challenge
[01]
PSD2, Open Banking APIs, and PCI-DSS v4.0 create a dense compliance landscape. FinTechs must demonstrate security maturity to regulators, card schemes, and banking partners simultaneously.
[02]
FinTech growth depends on shipping fast. Security is often bolted on after the fact, leaving payment flows, customer data, and fraud controls exposed as the product scales.
[03]
Open Banking and embedded finance architectures expose hundreds of API endpoints. Business-logic vulnerabilities in payment and account APIs are not caught by standard scanners.
[04]
Series A and beyond, banking partner onboarding, and card scheme certification all require demonstrable security posture, often on short timelines with limited internal resource.
