Cybersecurity in FinTech Industry – How to Build a Financial App with Proactive Security Measures?

Picture a landscape where all your financial transactions are done in a blink of an eye, investments are managed with a swipe, loans are approved with a tap, and where financial technology is transforming the way we manage money. Welcome to the world of cybersecurity in FinTech industry!

With new platforms and applications developed every day, the fintech (financial technology) industry has grown exponentially over the past few decades. Statista reveals, as of May 2023, there were nearly 11,651 fintech startups in the US (the highest in the world), followed by 5,061 in the Asia Pacific and 9,681 in the EMEA (Europe, the Middle East, and Africa).

With the rapid growth of fintech companies, the number of mobile banking users is also increasing at an unprecedented rate. According to Statista, the number of digital banking users in the US is projected to reach 217 million by 2025, from 197 million in 2021. With the ease and convenience mobile banking offers to users, this number may go even beyond the estimation.

With the unprecedented escalated number of users embracing the digital financial revolution, there exists a pressing need to bolster fintech cybersecurity.

Why is FinTech Cybersecurity Important for Businesses?

Data breaches and cyber-attacks are frequently in the news as hackers are constantly active in tampering with vulnerable data and breaching security protocols. A successful attempt by such hackers can not only cost millions of dollars to companies but also tarnish their overall brand reputation and credibility in the market.

For instance, Equifax, an American multinational consumer credit reporting company, faced one of the biggest data breaches of the century, which cost them nearly $4 billion in just a few days. The loss far outweighed the cost of putting strong security measures in place. It has proven to be true, as two years after the breach, the company spent around $1.4 billion on cleanup costs, which included improving app and data security costs and transforming IT infrastructure costs. Conversely, a secure fintech app development costs only $50,000 to $200,000 (more details later).

Here are some other examples of fintech cyber attacks reported in 2022:

• The OP Financial Group, the biggest financial firm in Finland with 180 cooperative banks and 2 million customers, suffered a cyberattack in which phishing messages, claiming to be from OP Group, asked the recipients to click on a link to confirm the payment.
• Qubit Finance, a decentralized lending and borrowing platform, was exploited by hackers and compromised nearly $80 million worth of cryptocurrency.
• TransUnion, a credit report agency, suffered from a massive data hack by ‘N4aughtysecTU’. This hacker group demanded a $15 million ransom over four terabytes of compromised data.

So, what are your security protocols to stay safe from such incidents and not fall prey to any malicious cyber attacks? What are your best practices to make a highly secure and compliant financial platform for your customers?

Well, with the swift growth in mobile banking users, building a custom fintech app with strong security measures can be your ultimate rescue against such threats. Let’s dive in to understand how to build a secure financial application in 2023.

How to Build a Secure FinTech App?

There has never been a greater way to ensure cybersecurity in the fintech industry than building a custom mobile application with strong security measures.

According to Statista, 43.5% of US consumers prefer using mobile banking to access accounts, making it the most prevalent banking method. However, building a secure fintech application is a complex and time-consuming task that requires relevant experience, expertise, and awareness of fintech security compliances such as PCI-DSS and GDPR.

While the steps to build a fintech app are similar to any other mobile app development, understanding the fintech cybersecurity best practices is crucial to ensure the ongoing success of your fintech application. Thus, here is a step-by-step guide on how to build a secure fintech app:

Define Your App’s Purpose

The first step to fintech app development starts with defining the purpose of your fintech app. Figure out what type of fintech app will best serve your needs. Would you require a solution for mobile banking, peer-to-peer lending, investment management, loan sanction, or any other financial service? Gaining a clear understanding of your app’s purpose will help you build the right type of app that will cater to the needs of your target audience.

Outline the Features and Functionalities

Now, based on your product’s purpose, outline the core features and functionalities of your fintech app. No matter what specific purpose your app serves, you must consider adding the basic security features like user authentication, secure transactions, account management, personalized notifications, real-time data updates, and analytics; and build a roadmap for development.

Design Intuitive User Interface

An intuitive interface is the lifeblood of any application, and a fintech app is no exception. So, build an easy-to-navigate and visually appealing interface that guides users through various functions. Pay attention to convenience, accessibility, security, and transaction flows to ensure a seamless UI/UX design.

Develop, Test and Deploy the App to the Market

Now, it is time to begin with the development process. Use the right tech stack and follow agile methodologies to develop a cutting-edge, secure, and robust fintech application. Once developed, conduct thorough testing to identify and resolve any bugs or glitches before launching it to the market.

Analyze, Monitor, and Iterate

Your fintech app development process does not end at its successful deployment. You need to constantly monitor your app’s performance, feedback, user engagement, scalability, and security to ensure its ongoing success in the fintech industry. You can use analytics tools to gain insights into user behavior and stay up-to-date with the security standards to iterate and enhance the app’s performance based on market trends and user feedback.

App Development Cost for Cybersecurity In FinTech Industry

The cost of developing a secure financial app varies depending on several factors, such as the platform(s) the app will be created for, the type of app, the app’s features and complexity, the level of security it provides, and the location of the fintech app development company.

Each of these factors significantly contributes to the overall app development cost. Therefore, it is challenging to provide an exact cost of fintech app development without knowing your specific requirements. To give a rough estimate, fintech app development cost can range somewhere from $50,000 to $300,000 or more, depending on the factors mentioned above.

Now that you know the basic steps to build a secure fintech app and its associated costs, let’s discover the best practices to keep your application safe from cybercrime and gain a competitive advantage.

Best Practices to Ensure Cybersecurity in Fintech Industry

With the ever-increasing risk of data breaches and cybercrime, the importance of integrating proactive security measures into fintech applications has become higher than ever. A small incident of a security breach in a fintech app can result in major financial losses, legal implications, and reputational damage. So, you must incorporate the best practices when building a fintech app security solution.

Comply with Industry Standards and Regulations

The fintech industry is highly regulated. Therefore, to protect users’ data and ensure cybersecurity, you need to familiarize yourself with the regulatory standards. Ensure your app adheres to general regulations such as Anti-Money Laundering (AML), Know Your Customer (KYC), PCI-DSS, and General Data Protection Regulation (GDPR) to build trust and compliance.

Secure Data Storage

Building a secure fintech solution means integrating security at every stage of the application. Therefore, when building a fintech cybersecurity app, you need to ensure what data to store, where to store it, who will access your app, and more. Try to keep your app’s architecture simple and store only the minimal crucial data so that hackers can’t steal sensitive information from your system. For instance, build a secure payment gateway that does not ask for the customers’ card numbers. Regularly testing the data restoration process is also essential to ensure data integrity.

Write Secure App Code

Secure coding is the backbone of a fintech application. If your code has even the smallest vulnerabilities, your entire effort of building a secure application may go in vain, bringing your business at risk. Therefore, the tech experts who deploy the code should consider proper logging, input validation, password management, handling of errors, authentication, cryptography practices, and secured communication.

Implement Secure APIs, Data Encryption, Two-Factor Authentication

The success of the fintech industry heavily relies on the security and scalability of financial solutions. Therefore, when building a fintech app, integrate strong security measures such as biometric identification, two-factor authentication, data encryption, and secure APIs.

Biometric Identification: The biometric technology adds an extra layer of security to the application by allowing users to access the fintech solution only with their unique biometric data, such as facial recognition or fingerprints.

Multi-Factor Authentication: Multi-factor authentication asks users to provide two or more forms of identification to access the application. For instance, users need to use a password and an OTP sent to their mobile device before accessing their accounts.

Data Encryption: Data encryption is one of the best practices to secure financial information. Add a strong data encryption feature to protect sensitive user data at rest and during transmission, ensuring that hackers can’t gain unauthorized access and interpret the information.

Application Programming Interfaces (APIs): Fintech app security solutions interact with various third-party services through APIs. Therefore, your fintech cybersecurity strategies must include the security of these APIs to prevent dubious access and potential data breaches.

By integrating these cybersecurity solutions and security features into the fintech applications, businesses can successfully face the fintech cybersecurity risks while building a secure and resilient digital financial ecosystem.
