A digital bank represents a new age of banking, operating primarily online without the reliance on traditional physical branches. It employs technology to offer various services, such as savings and current accounts, loans, and investment opportunities. The crux of its appeal lies in the 24/7 accessibility, enabling users to conduct banking operations anytime, anywhere, provided they have an internet connection. For a country like Bangladesh, this innovation promises a transformative shift in banking, especially for regions previously underrepresented in the traditional banking system.
Digital banks, or neobanks or challenger banks, have been designed to cater to various financial needs by offering innovative and technology-driven services. While the terminologies can sometimes overlap, there are some distinctions. Here are the primary types of digital banks:
Retail Digital Banks:
These cater to the everyday banking needs of individual consumers. They offer savings accounts, checking accounts, loans, and payment solutions. Customers can manage their finances, transfer money, and even make payments directly through apps or websites. Examples include Monzo, Starling, and N26.
Business Digital Banks:
These are designed for businesses, startups, and entrepreneurs. They provide services like business accounts, payment processing, and expense management and often integrate with accounting software. Examples are Tide, Qonto, and Mercury.
Investment Digital Banks:
These platforms are focused on investment services. They might offer robo-advisory services, stock trading, or other investment solutions. Betterment and Wealthfront are good examples.
Wholesale and Transaction Banks:
These digital platforms provide services to other banks or large financial institutions. They may facilitate large transactions, trading services, or other B2B financial processes.
Open Banking Platforms:
This is a newer concept wherein banks provide a set of APIs that third-party developers use to build applications and services. It allows consumers to share access to their financial data, enabling third-party companies to create new financial products around them.
Marketplace Banks or Banking-as-a-Service (BaaS):
These platforms allow third parties to offer financial products within a bank’s ecosystem. It’s like an app store but for banking products. The bank provides the infrastructure, while third parties provide specific services.
Neo-Banks:
While often used interchangeably with digital banks, neo-banks usually operate without traditional banking licenses. They frequently partner with conventional banks to offer services, focusing primarily on user experience and unique features.
Challenger Banks:
These banks challenge the dominance of traditional banks by offering a fully licensed service with a primarily digital model. They often combine features of retail and business banking.
As the banking industry evolves, these categories might see more subtypes emerge, driven by technological advancements and changing consumer needs. The distinction between each type might also blur as digital banks diversify their offerings to cater to a broader audience.
Cybersecurity Challenges in Digital Banks
With great innovation comes great responsibility. One of the primary concerns of digital banks is cybersecurity. Being wholly reliant on online operations makes them susceptible to diverse cyber threats like data breaches, phishing scams, and malware attacks. Furthermore, the limited internet penetration and digital literacy in parts of Bangladesh can exacerbate these risks, as uninformed users might be more prone to falling for cyberattacks.
Adopting digital banking in Bangladesh, especially given the mentioned challenges, amplifies the cybersecurity risks associated with digitising financial services. Here are some specific cybersecurity risks that Bangladesh may face:

Given the relatively low levels of digital literacy, users may inadvertently download malicious software that can steal or encrypt data and demand ransom.
Man-in-the-Middle Attacks (MitM):
Attackers may intercept communication between the user and the bank, capturing sensitive data during the transaction process.
DDoS Attacks:
Digital banks may become targets for Distributed Denial of Service attacks, disrupting banking operations and eroding trust.
Unsecured Mobile Applications:
If the mobile apps of digital banks are not coded securely, they might be vulnerable to attacks, leading to data breaches.
Weak Authentication Protocols:
Without robust authentication mechanisms like two-factor authentication (2FA) or biometric verification, digital bank accounts may be easier to breach.
Insider Threats:
Employees or individuals accessing the digital bank’s infrastructure might exploit the system for malicious or personal gain.
Unsecured APIs:
Many digital banks integrate third-party services using Application Programming Interfaces (APIs). If not secured properly, these can become entry points for attackers.
Data Breaches:
Given the large amount of personal and financial data stored, digital banks are lucrative targets for cybercriminals. Inadequate security measures can lead to significant data breaches.
