The financial technology (FinTech) sector is not just growing; it is fundamentally reshaping global commerce. With the global FinTech market projected to hit over $1.13 trillion by 2032, the opportunity for disruption is immense. However, building a FinTech app is not the same as building a standard mobile application. It is a high-stakes endeavor where the cost of failure is measured in regulatory fines, irreparable reputational damage, and lost user trust.
As a Founder, CEO, or CTO, you need a partner who understands that security and compliance are the foundation, not an afterthought. You need a clear, repeatable, and scalable framework to navigate this complex landscape. This guide, developed by Cyber Infrastructure (CIS) experts, provides the strategic blueprint for how to develop a FinTech app that is not only innovative but also compliant, secure, and future-proofed with AI-enabled capabilities.

Key Takeaway: Security is your FinTech app's primary feature. Non-compliance is a business-ending risk. Your development partner must demonstrate verifiable process maturity (CMMI Level 5) and adherence to global security standards.
In FinTech, you are handling people's most sensitive data and their money. This is why security is not a department; it is a core engineering discipline. The financial services industry is a prime target for cybercriminals, and the cost of a breach can be catastrophic.
Critical Compliance Standards Your App Must Meet
Before a single line of code is written, your FinTech app must be architected to satisfy a complex web of global and regional regulations. CIS, as an ISO 27001 and SOC 2-aligned organization, embeds these requirements into our Secure, AI-Augmented Delivery model:
- PCI DSS (Payment Card Industry Data Security Standard): Mandatory for any app that stores, processes, or transmits cardholder data.
- GDPR (General Data Protection Regulation): Essential for protecting the personal data of users in the EMEA region.
- AML (Anti-Money Laundering) & KYC (Know Your Customer): Core requirements for identity verification and suspicious activity monitoring, crucial for building trust and avoiding legal penalties.
- ISO 27001 & SOC 2: These certifications demonstrate a systematic approach to managing sensitive company and customer information, providing C-suite peace of mind.
CIS Expert Insight: Up to 98% of global FinTech startups have been found vulnerable to cyber-attacks. This is often due to treating security as a bolt-on feature. Our approach is to integrate DevSecOps from the initial sprint, leveraging our Cyber-Security Engineering Pod to ensure continuous compliance and threat mitigation.
