Use Secure Coding Practices

Creating secure code from the outset is your first layer of protection against cyber threats. With 42% of web applications vulnerable due to insecure coding practices, it’s clear that secure development isn’t just optional - it’s essential. Adopting secure coding doesn’t mean overhauling your entire process; it’s about making thoughtful, security-focused decisions at every step.

Follow Secure Coding Standards

Frameworks like OWASP offer a reliable foundation for securing web applications. The OWASP Foundation underscores this, stating:

"The OWASP Top 10 is a standard awareness document for developers and web application security. It represents a broad consensus about the most critical security risks to web applications."

Secure coding revolves around eight key principles: input validation, output encoding, authentication, session management, access control, cryptographic practices, error handling, and logging. For example, adopting a "default deny" approach to permissions ensures users only access what they’re explicitly authorised to. Require authentication for all resources except those specifically intended for public access, and avoid exposing sensitive details in error messages.

To defend against SQL injection - responsible for 94% of web application attacks in 2025 - use strongly typed parameterised queries. Additionally, never pass user-supplied data directly into dynamic include functions.

Use Code Analysis Tools

Static code analysis tools are invaluable for spotting vulnerabilities early in development. These tools automate quality checks, helping to identify coding flaws during the Software Development Life Cycle (SDLC). SAST (Static Application Security Testing) tools integrate with your IDE, providing real-time scanning as you write code. When selecting a tool, ensure it supports the programming languages your team uses and integrates with your source code manager. Many tools also provide remediation guidance, simplifying the process of addressing detected issues. Focus on triaging results to prioritise and resolve the most critical vulnerabilities.

Validate Inputs and Update Dependencies

Proper input validation is key to preventing unauthorised access, data leaks, and other security breaches. Validation should occur on both the client and server sides. While client-side validation offers immediate feedback to users, server-side validation acts as the ultimate safeguard. Use techniques like regular expressions to ensure inputs meet specific patterns, and favour a whitelisting approach over blacklisting.

Dependency management is just as important. With 77% of open source projects relying on libraries with known vulnerabilities and 89% of issues linked to outdated components, keeping dependencies up to date is critical. Use automated tools to monitor and update third-party libraries and system components regularly.

Encrypt Data End-to-End

Securing data from start to finish with end-to-end encryption (E2EE) is no longer optional - it's a necessity. In 2024, the financial sector faced an average cost of £4.9 million per data breach, with 65% of FinTech firms encountering ransomware attacks. These figures underline why robust encryption is essential for protecting sensitive information and maintaining trust.

E2EE ensures that only the sender and the intended recipient can access the data. Even if intercepted or compromised during a server breach, the information remains unreadable. This approach not only safeguards data during transmission but also helps meet regulatory requirements like GDPR, HIPAA, and CCPA. For FinTech companies, where user trust is paramount, encryption is a cornerstone of staying competitive. Below, we explore the protocols that underpin strong encryption practices.

Use Advanced Encryption Protocols

To protect data, employ AES-256 encryption for data at rest and TLS 1.3 for data in transit. These protocols are designed to maintain both confidentiality and integrity.

Incorporate Hardware Security Modules (HSMs) and ensure regular key rotations to minimise vulnerabilities. Automating this process can significantly reduce the risk of human error. For added security, apply full disk encryption to all servers and database encryption to fields containing sensitive data.

When managing encryption, rely on proven libraries and cloud-native tools instead of developing custom solutions. This approach not only reduces implementation errors but also ensures compliance with industry standards. Additionally, consider supplementing encryption with tokenisation and data masking to further limit exposure to sensitive information.

Apply Tokenisation and Data Masking

Tokenisation and data masking add extra layers of protection by reducing the storage of sensitive information. Tokenisation replaces sensitive data, such as credit card numbers or bank account details, with non-sensitive tokens stored securely in a token vault. This means that even if a database is compromised, attackers gain access only to meaningless tokens instead of actual financial data.

The process works by substituting sensitive elements with randomly generated tokens that retain the same format and length as the original data. This allows systems to operate as usual while significantly lowering security risks.

Data masking, on the other hand, is particularly useful in non-production environments. During development, testing, or training, masked data provides realistic datasets without exposing actual customer information. For real-time protection, implement dynamic data masking, which adjusts access to sensitive information based on user roles. This ensures that individuals only see the data they need for their tasks.

In cases where maintaining data relationships and referential integrity is critical, consider using format-preserving encryption alongside tokenisation. Regularly auditing your tokenisation and masking processes - such as reviewing access logs, monitoring token usage, and conducting periodic assessments - will help ensure that sensitive data remains protected at all times.

Strengthen Identity and Access Management

Managing who can access your FinTech application is a critical step in safeguarding sensitive financial data. With the financial services sector ranking as the second most targeted industry for cyberattacks in 2023, implementing strong identity and access management measures is no longer just a recommendation - it’s a necessity.

The challenge goes far beyond simple password protection. A staggering 73% of people reuse their passwords across multiple accounts, and in 2023 alone, 22 billion credentials were exposed in data breaches. For FinTech startups, which handle sensitive financial information, introducing advanced access controls is essential to earning user trust. In fact, 53% of consumers associate multi-factor authentication (MFA) with greater security. This highlights the importance of a layered security strategy, starting with robust MFA.

Set Up Multi-Factor Authentication (MFA)

Multi-factor authentication adds an extra layer of protection by requiring users to verify their identity using at least two different factors: something they know (like a password), something they have (such as a smartphone), or something they are (biometric data). This approach significantly reduces the risk of unauthorised access, even if passwords are compromised.

When selecting an MFA method, consider your specific security needs:

• SMS-based authentication is straightforward and familiar to most users but is vulnerable to SIM-swapping attacks, which surged by 400% in 2022.
• App-based authentication offers better security by avoiding reliance on mobile networks, though it requires users to install an additional app.
• Biometric authentication provides both security and convenience but comes with the caveat that biometric data cannot be reset if compromised.
• Hardware tokens deliver a high level of security but may be inconvenient if lost and can be costly to implement.

To strengthen your defences, consider risk-based MFA, which adapts authentication requirements based on the level of risk. For instance, stricter measures can be applied to high-risk transactions or unusual login attempts, such as access from unfamiliar devices or locations. This approach helps balance security with usability, addressing the 48% user drop-off rate caused by overly complicated sign-up processes. Partnering with trusted third-party MFA providers that support standards like OAuth 2.0 and SAML can streamline implementation.

By making the authentication process seamless - offering clear onboarding instructions and recovery options - you not only protect sensitive data but also build user confidence in your platform.

Use Role-Based Access Control and Zero-Trust Principles

Role-based access control (RBAC) limits system access based on predefined roles rather than individual identities. This reduces the attack surface by ensuring users only have the permissions necessary for their specific roles. For example, customer service representatives might access account details without the ability to approve transactions, while compliance officers might view audit logs but not modify customer data. Banks often use RBAC to ensure tellers can process deposits but not approve loans, and companies like GitHub assign roles such as Admin, Write, or Read to control access.

To implement RBAC effectively, follow the principle of least privilege: grant users only the minimum permissions they need to perform their jobs. Start with a small set of core roles and expand as needed, maintaining clear hierarchies to avoid overlap or excessive complexity.

Combining RBAC with zero-trust principles takes security a step further. Zero-trust means no user or device is trusted by default, and every access request is verified - even if the user has previously authenticated. This approach is increasingly relevant as organisations juggle an average of 364 SaaS applications and 1,295 cloud services. Using a centralised identity and access management (IAM) solution can simplify user management, automate role assignments, and enforce policies effectively.

Review Access Permissions Regularly

Regularly reviewing access permissions is crucial to prevent privilege creep and minimise insider threats, which account for about 35% of data leaks in the financial sector. Outdated access rights can create security vulnerabilities and inefficiencies.

Start by documenting a clear access control policy that outlines how access is granted, reviewed, modified, and revoked. Determine review frequency based on the sensitivity of the data and compliance requirements. For high-risk systems, monthly reviews may be necessary, while quarterly reviews might suffice for less critical applications.

Assign responsibility for reviews to specific individuals, such as managers for team permissions or IT security teams for technical roles. Detailed user access reports can help ensure that current permissions align with job responsibilities. Automating this process with specialised tools can identify risks and streamline audits, especially in complex environments.

During these reviews, focus on tracking "joiners, movers, and leavers." Ensure new hires are granted appropriate access from day one, adjust permissions when employees change roles, and immediately revoke access when someone leaves the organisation. Providing regular cybersecurity training can also reinforce the importance of these reviews and strengthen your overall security framework. Regular access reviews are not just a regulatory requirement - they are a key practice for maintaining security and earning customer trust in your FinTech startup.

Build Secure Infrastructure

Creating a secure infrastructure is essential for safeguarding FinTech applications. With cyber threats targeting financial services more aggressively than ever, your infrastructure needs to be resilient enough to withstand advanced attacks.

A strong infrastructure goes beyond basic security measures. It involves meticulous planning of network architecture, the strategic use of security tools, and constant monitoring of your application's runtime environment. The idea is to establish multiple layers of defence, making it significantly harder for attackers to access sensitive financial data. Key components include using Virtual Private Clouds (VPCs), implementing layered defences, and deploying advanced runtime protection mechanisms.

Use Virtual Private Clouds (VPCs)

Virtual Private Clouds (VPCs) are a powerful tool for FinTech startups to keep sensitive data isolated from public networks while still benefiting from the flexibility of cloud computing. VPCs enable you to create private network environments that are customisable and secure.

The primary advantage of VPCs is their ability to isolate different parts of your business operations. For instance, you can set up separate VPCs for development, testing, and production environments. This ensures that a security breach in one area doesn’t compromise the entire system. Within a VPC, you can configure subnets and apply detailed access controls using tools like security groups, network access control lists (ACLs), and cloud firewall rules. For example, payment servers can be restricted to specific IP addresses, while customer service teams can access data only through designated pathways.

Additionally, VPCs support strong encryption for data both in transit and at rest. This means that even if intercepted, the data remains unreadable without the proper decryption keys. Compared to traditional VPNs, which extend the network perimeter and can introduce risks, VPCs offer better isolation - an essential feature for managing sensitive customer information.

Set Up Layered Defences

Layered defence, often referred to as "defence in depth", involves stacking multiple security measures to create a robust protection system. If one layer is compromised, the remaining layers continue to shield your systems.

A solid layered defence strategy includes:

• Perimeter and Network Security: Use tools like web application firewalls (WAFs), intrusion detection systems (IDSes), and network segmentation to block malicious traffic before it reaches your applications.
• Host and Endpoint Security: Enforce strict access controls, such as multi-factor authentication and account lockout policies. Deploy endpoint detection and response (EDR) tools and continuously monitor devices for suspicious activity.
• Application Security: Follow secure coding practices, implement thorough input validation, and ensure strong authentication and authorisation processes to prevent unauthorised access.
• Data Security: Classify data by sensitivity, encrypt it both during transmission and storage, and use data masking techniques for added protection during development and testing.

The strength of layered defences lies in their redundancy and constant monitoring. By applying principles like encryption, least-privilege access, and a zero-trust model across all layers, you create a cohesive security system that significantly boosts your resilience.

Deploy Runtime Application Self-Protection (RASP)

Runtime Application Self-Protection (RASP) offers an advanced layer of security, particularly for FinTech applications that handle real-time transactions. RASP works from within your application, analysing its behaviour and execution patterns to detect and block threats as they happen.

Unlike traditional security tools that operate outside the application, RASP takes an inside-out approach. It monitors real-time activity within the application, allowing it to detect sophisticated attacks, including zero-day exploits targeting previously unknown vulnerabilities.

When RASP identifies suspicious activity, it intercepts and neutralises threats before they cause damage. This real-time response is critical for FinTech applications, where even a brief delay in addressing an attack can lead to substantial financial losses or data breaches.

However, RASP should not be seen as a standalone solution. It is most effective when used alongside other security measures, such as WAFs and regular vulnerability assessments. Together, these tools provide comprehensive protection against both known vulnerabilities and emerging threats in today’s fast-changing threat landscape.

Run Regular Vulnerability Assessments

Running regular vulnerability assessments is like giving your security system a health check - it helps uncover weak points before attackers can exploit them. This proactive approach is especially critical in sectors like finance, where the stakes are incredibly high.

Consider this: in 2024, the average cost of a data breach in the financial sector hit a staggering £4.9 million, compared to £3.9 million across other industries. And between January and June 2024 alone, over 20,000 vulnerabilities were reported. With threats evolving so quickly, FinTech companies must constantly stay ahead. These assessments should cover everything - from network infrastructure to application code - and be conducted regularly. They lay the groundwork for thorough testing and timely fixes.

Perform Penetration Testing and Code Reviews

Penetration testing and code reviews are two critical tools in your security toolkit. They dig deeper than automated checks, revealing vulnerabilities that might otherwise go unnoticed.

Penetration testing mimics real-world attacks to expose weaknesses. To be effective, it should follow recognised frameworks like the OWASP Testing Guide or NIST 800-115. Combining automated scanning with manual testing is key. Automated tools can quickly flag common issues, while manual testing can uncover more complex flaws and even zero-day vulnerabilities that require a human touch.

For FinTech applications, focus penetration testing on high-risk areas such as payment systems, customer authentication, and data transmission. Both internal tests (to simulate insider threats) and external tests (to mimic outside attacks) are essential for a comprehensive approach.

Code reviews, meanwhile, have become smarter thanks to AI-powered tools that can assess how changes in code affect overall system security. By integrating these reviews into your development cycle, you can catch issues before they make it to production.

"Code reviews play a key role in maintaining software quality, security, and compliance by detecting vulnerabilities, enforcing best practice coding standards, and refining design early in the software development cycle." - Wiz

The cost of fixing a flaw post-launch can be up to 100 times higher than addressing it during development. When reviewing code, pay close attention to areas like authentication, data validation, and encryption. Be on the lookout for common threats like SQL injection, cross-site scripting, and insecure direct object references - issues that could jeopardise sensitive financial data.

Keep Software Up-to-Date

Keeping software up-to-date is one of the simplest yet most effective ways to strengthen your security. Many high-profile breaches, including the Equifax and Hatch Bank incidents, stemmed from unpatched vulnerabilities.

Adopt a risk-based approach to patching. Critical vulnerabilities, especially those affecting internet-facing systems, should be addressed within 24–48 hours. Lower-risk issues, like those in internal systems, can follow a more flexible timeline.

Your patching process should include several steps: use automated vulnerability scanners to identify systems needing updates, test patches in a staging environment before rolling them out, and have rollback procedures ready in case something goes wrong. Don’t forget about third-party components - modern applications often rely on external libraries and frameworks, each of which could become an entry point for attackers. Regularly monitor and update all third-party dependencies to minimise risks.

Document and Act on Assessment Findings

Once vulnerabilities are identified and patched, it’s crucial to document everything and act on the findings. Effective vulnerability management isn’t just about spotting issues - it’s about systematically addressing them.

Create detailed reports that cater to different audiences. Include technical specifics for your development team and high-level summaries for leadership. Each vulnerability should be documented with its severity, potential attack vectors, affected systems, and recommended fixes.

Prioritise remediation efforts based on both technical severity and business impact. For instance, a critical flaw in your payment system should take precedence over a similar issue in a development environment. Here’s a practical framework for prioritisation:

• Critical: Actively exploited vulnerabilities (fix within 24–48 hours)
• High: Vulnerabilities in internet-facing systems (fix within 1–2 weeks)
• Medium: Issues in internal systems (fix within 30 days)
• Low: Minimal impact vulnerabilities (address during the next maintenance window)

Track progress closely, and conduct follow-up testing to ensure fixes are effective. Maintaining detailed records of all assessments, findings, and remediation efforts is invaluable for regulatory compliance and provides a historical reference for future security improvements. These records also help identify recurring issues, making it easier to measure the long-term effectiveness of your security programme.

Vulnerability assessments should be an ongoing process. As soon as one round of remediation is complete, the next scan should begin. This continuous cycle ensures your security measures keep pace with evolving threats and the growing demands of your business.

Focus on Fraud Prevention Measures

Protecting financial transactions goes beyond securing code and infrastructure - it requires robust fraud prevention strategies. In 2022, global online payment fraud losses reached a staggering £33 billion, with projections suggesting this could climb to £39 billion by the end of 2023. Additionally, digital fraud attempts increased by 39% between 2019 and 2022. Unlike traditional security measures that focus on blocking attackers, fraud prevention continuously examines transactions and user behaviours, acting as an essential layer of defence alongside technical security protocols.

Monitor Transactions for Suspicious Activity

Transaction monitoring plays a key role in fraud prevention. This automated process continuously analyses financial activities to identify and flag anything unusual. By using rule-based criteria, risk scoring, pattern recognition, and machine learning, these systems establish a baseline for normal user behaviour. For instance, if a customer suddenly makes multiple large transactions to high-risk regions - deviating from their usual activities - the system triggers an alert. Compliance teams can then step in to investigate and, if necessary, take actions like blocking payments, freezing accounts, or notifying authorities. This method helps combat a range of threats, including money laundering, account takeovers, synthetic identity fraud, card fraud, and social engineering schemes.

Use Automated Fraud Detection Tools

Automated fraud detection tools, powered by artificial intelligence, are transforming the way organisations tackle fraud. These tools analyse transaction patterns, user behaviours, and historical data to identify anomalies, a method widely adopted by leading FinTech companies. The market for AI in FinTech is expected to reach approximately £43 billion by 2030.

Implementing such tools requires careful planning. Organisations must allocate budgets for AI and machine learning solutions, ensure datasets are high-quality and unbiased, and adopt explainable AI techniques for greater transparency. Regular audits of machine learning models are also crucial to identify and address potential biases. AI further strengthens fraud prevention through biometric authentication methods like facial recognition and fingerprint scanning. It also simplifies compliance by automatically monitoring transactions and flagging potential regulatory breaches.

Add Behavioural Analytics

Behavioural analytics takes fraud prevention a step further by monitoring user interactions - such as typing patterns, mouse movements, and login times - to detect unusual activity. These systems build detailed digital profiles over time, making it easier to spot deviations. Research shows that behavioural analytics, combined with machine learning, can prevent up to 90% of fraud, while early detection can cut fraud costs by as much as 42%. Organisations using these techniques report annual detection rate improvements of 50–90%. The behavioural biometrics market is also on the rise, with projections estimating it will reach £10.5 billion by 2033, growing at an annual rate of 23.8% from 2023.

"Using NeuroID decisioning, we can confidently reject bad actors today who we used to take to step-up. We also have enough information on good applicants sooner, so we can fast-track them and say 'go ahead and get your loan, we don't need anything else from you.' And customers really love that." - Mauro Jacome, Head of Data Science for Addi

To effectively implement behavioural analytics, organisations should start by gathering relevant data, such as transaction logs, user activity, and device details. By segmenting users and defining normal behaviours, machine learning models can be trained to detect anomalies. Real-time monitoring of these anomalies, combined with risk scoring and contextual analysis, allows for swift action, such as locking accounts or flagging transactions. Over time, as the system processes more data, its accuracy improves, making behavioural analytics a powerful tool for both preventing fraud and enhancing the experience for legitimate users.

Meet Regulatory Standards

For FinTech startups in the UK, complying with regulatory standards isn't just a box-ticking exercise - it's a fundamental part of doing business. While the UK offers a supportive environment for financial innovation, it also enforces strict compliance requirements that can significantly influence operations.

Follow UK and International Regulations

UK-based FinTech firms must navigate a range of financial regulations, which vary depending on their activities, size, and risk profile. Two key regulatory bodies oversee the sector: the Financial Conduct Authority (FCA), which focuses on conduct risk, and the Prudential Regulation Authority (PRA), which ensures the financial soundness of firms. Compliance areas include anti-money laundering (AML) protocols, data privacy laws (GDPR and UK GDPR), and consumer protection standards. To engage in regulated activities, FinTechs must secure FCA authorisation.

Specific rules also apply to niche sectors. For instance, cryptoasset exchanges and wallet providers have been subject to AML requirements since 2017. Additionally, the UK GDPR extends its reach beyond the EU, covering businesses outside the UK that offer goods or services to individuals within the UK. Licensing is another critical consideration. For example, Electronic Money Institution (EMI) licences demand higher initial capital but allow firms to hold customer funds indefinitely, unlike Payment Institutions.

Beyond licences and compliance mandates, maintaining thorough documentation is vital for regulatory adherence.

Keep Detailed Audit Trails

Regulators require FinTech companies to keep detailed and well-organised records of transactions and customer information. These audit trails are essential for passing regulatory reviews and protecting your business during inspections. Poor record-keeping can lead to severe penalties; for example, in 2022, Wise faced a fine of approximately £280,000 from Abu Dhabi's regulator for failing to maintain adequate AML controls.

To ensure compliance, develop a clear policy for managing records - this includes creating, storing, and accessing documentation, as well as adhering to mandated retention periods. Regular internal reviews and appointing a dedicated compliance officer to handle regulatory inquiries can streamline the audit process.

But compliance isn’t just about systems and paperwork - it’s also about your team.

Train Staff on Regulatory Requirements

Your team’s understanding of compliance is a cornerstone of effective regulatory adherence. FinTech companies, particularly those involved in cryptocurrencies, face significant risks of financial crime due to factors like cross-border operations and user anonymity. Recent penalties imposed on major cryptocurrency exchanges highlight the dangers of insufficient customer verification processes.

To mitigate these risks, provide your staff with regular compliance training and workshops. These sessions should cover the latest regulations, policies, and procedures, tailored to the specific risks associated with their roles. Regularly assess your company’s training needs, review gaps in compliance knowledge, and choose training providers who can customise courses to your requirements. Staying informed about regulatory changes is equally important, and consulting experienced legal advisors can help navigate complex requirements while avoiding costly mistakes.

Conclusion

Securing FinTech web applications is no longer optional - it's a necessity in today’s high-risk environment. In 2023, finance overtook healthcare as the most breached industry, with 40% of FinTech companies reporting a cyber incident within the year. By 2024, the average financial data breach cost soared to £4.8 million, far exceeding the cross-industry average of £3.9 million.
