Money never sleeps. And neither do cybercriminals.
The rise of neobanks and digital wallets has simplified the process of financial services. In seconds, you can wire money, pay a bill or check your balance. No matter how convenient it is, though, such a system bears an enormous responsibility: protecting every transaction and every user account from being compromised.
The security audit is the foundation of that safety. A security audit looks at your systems, locates weaknesses and gives you the opportunity to fix them before bad guys can exploit them. But performing manual audits of these transactions is slow, costly and prone to errors.
That’s where smart apps can help.
Today, we are going to dissect 6 intelligent applications that help you cover your bases when it comes to neobank and digital wallet security audits. These are the tools that real fintech teams all over the world use. They help pinpoint threats more quickly, automate tedious tasks and give security teams a clearer understanding of what is happening inside their systems.
Let us get into it.
How (And Why) Security Audits Are So Important for Neobanks
But before we get into the apps, let’s take a look at why this is such an important topic right now.
Neobanks operate entirely online. There are no physical branches. No in-person verification. All transactions go through an app or a website. Which makes them incredibly convenient — and incredibly vulnerable.
Digital wallets face similar challenges. They house financial data, connect to bank accounts and handle thousands of transactions per minute. One security hole can impact millions of users.
The Numbers Are Terrifying
Cybersecurity research indicates that financial services companies experience cyberattacks at a higher rate than nearly any other sector. Phishing, account takeovers, API vulnerabilities and data breaches are all common threats.
Regulators are paying attention too. Fintech companies are required to perform regular security audits by certain regulations like PCI DSS, GDPR and regional banking laws. Skip them — or execute them poorly — and you risk enormous fines and trust deficits.
With the help of smart security audit apps, fintech teams can adhere to these requirements while catching legitimate threats as they happen. If you want to stay on top of how modern banking tools are evolving, BankProfi is a great resource to explore neobank trends and financial technology insights.
What Makes a Smart Security Audit App Worth Using?
Not all the tools in the world are worth your time. Here are the characteristics of a truly smart security audit app developed for neobanks and digital wallets:
| Feature | Why It Matters |
|---|---|
| Automated scanning | Saves hours of manual work |
| Real-time alerts | Catches threats before they hurt |
| Compliance mapping | Ties audit results to regulations like PCI DSS |
| API security testing | Crucial for fintech platforms |
| Easy-to-read reports | Helps the rest of your team understand risk |
| Cloud-native support | Works with modern fintech infrastructure |
Now let’s go through the six apps that tick all those boxes.
App #1 — Qualys Cloud Platform
The Cloud-Native, Full-Stack Security Scanner
Qualys is among the most reputable names in cybersecurity. Banks, insurance companies and fintech startups around the world use their cloud platform.
For neobanks and digital wallets, Qualys has something very precious — 24/7 security monitoring. Rather than conducting audits once each quarter, Qualys continuously scans your entire environment.
How It Benefits Security Audits
Qualys maps your infrastructure automatically. It will discover every device, server, container and API endpoint that’s attached to your systems. That’s huge for neobanks that are built on cloud services such as AWS or Google Cloud.
It also runs vulnerability assessments. These checks compare your systems against thousands of known security vulnerabilities. And when it finds a problem, it is precise about what you need to fix.
Compliance Made Simple
One of the things Qualys does best is its built-in compliance reporting. It complies with standards such as PCI DSS, ISO 27001 and SOC 2. Your audit team can generate a compliance report in minutes instead of collecting data for days on end.
Best for: Mid-size to larger neobanks that require ongoing monitoring as well as compliance reporting.
Key features:
- Continuous asset discovery
- Vulnerability management
- Policy compliance scanning
- Cloud security posture management
App #2 — Burp Suite Professional
Web and API Security Testing Done Right
If your security team isn’t using Burp Suite, they’re likely missing something important. Burp Suite Professional is one of the most powerful tools for testing web applications and APIs — and digital wallets are comprised of both.
Why Fintech Teams Love It
Digital wallets communicate with each other through APIs all the time. Under the hood, when you review your balance or transfer money, an API call is made. Every one of those calls is an opportunity for attackers to enter.
Burp Suite allows security testers to intercept these API requests, modify them and then observe how the system responds. It’s the sort of testing known as penetration testing, or pen testing for short. It simulates what an actual attacker would do.
Finding Vulnerabilities Before Hackers Do
Burp Suite’s scanner looks for common bugs such as SQL injection, cross-site scripting (XSS) and authentication flaws. These are the same techniques used by hackers to break into fintech platforms.
For neobanks, this type of deep API testing is crucial. Most breaches occur not through the main app but through lesser-known API endpoints that were not thoroughly tested.
Automated + Manual Testing
Burp Suite combines automated scanning and manual testing tools. Your security team can allow the scanner to run on its own, but then investigate suspicious areas manually. This combination catches more problems than either individual approach alone.
Best for: Security engineers and pen testers working on neobank and digital wallet platforms.
Key features:
- API security testing
- Web vulnerability scanner
- Traffic interception and analysis
- Custom scripting with Burp Extender
App #3 — Vanta
Compliance Automation That Actually Works
Let’s be honest — compliance is tiring. Collecting evidence, writing policies, mapping controls to frameworks and preparing for audits is a lot of work.
Vanta was created precisely to address this issue.
What Vanta Does
Vanta automates the work involved in becoming and remaining compliant. It integrates with your current tools — AWS, Google Cloud, GitHub, Slack and dozens more — and keeps pulling evidence that you’re meeting your security responsibilities.
This is game-changing for neobanks. Rather than taking weeks to prepare for an audit, Vanta keeps your compliance posture constantly up to date.
Frameworks Supported
Vanta covers a broad variety of compliance frameworks that fintech companies actually care about:
| Framework | What It Covers |
|---|---|
| PCI DSS | Payment card data security |
| SOC 2 | Data security and availability |
| ISO 27001 | Information security management |
| GDPR | Data privacy (European users) |
| HIPAA | Health data (if relevant) |
Making Audits Faster
When an auditor comes calling, Vanta has all your evidence organized and ready to share. You can also bring auditors directly into the platform. They review what they need, and you’re finished.
It’s the kind of efficiency that growing neobanks need. You can’t have your whole team drop everything every time an audit comes around.
Best for: Neobanks and digital wallet companies that require ongoing compliance monitoring and expedited audit preparation.
Key features:
- Automated evidence collection
- Real-time compliance dashboards
- Auditor access portal
- Integration with 200+ tools
App #4 — Splunk Enterprise Security
Turning Data Into Security Intelligence
Every neobank generates vast quantities of log data. A record is created with each login attempt, every API call and every failed transaction. Splunk Enterprise Security takes all that data and turns it into actionable security intelligence.
What Is a SIEM and Why Does It Matter?
Splunk is what’s called a SIEM — Security Information and Event Management tool. It gathers logs from all of your systems and applies machine learning to search for patterns that look suspicious.
This is incredibly powerful for digital wallets. Consider receiving a notification the moment one of your users’ accounts begins making abnormal transactions at 3 AM from a previously unknown location. That is Splunk doing its job.
Security Audits With Splunk
Splunk offers a full timeline of activities across your environment during a security audit. Auditors can review logs to ensure security controls are functioning. They can also trace the root cause of any incident back to its source.
Pre-built PCI DSS compliance dashboards are also available with Splunk. These dashboards tell you clearly which requirements you are meeting and which may need some work.
Detecting Threats in Real Time
In addition to audits, Splunk helps fintech teams discover active threats. Its correlation rules can detect things like brute-force login attempts, unauthorized access to sensitive data or unusual API activity.
If it detects something threatening, Splunk can automatically take action — block an IP address, lock an account or alert your security team.
Best for: Larger neobanks and digital wallet platforms with complex infrastructure and high transaction volumes.
Key features:
- Real-time log analysis
- Threat detection and response
- PCI DSS compliance dashboards
- Custom alerts and automated responses
App #5 — Snyk
Protecting the Code That Powers Your Fintech App
Many security tools focus on the infrastructure. Snyk takes a different approach — it hones in on the code itself.
All neobanks and digital wallets are powered by software. That software has dependencies — libraries and packages created by third parties that developers use to roll out features more quickly. These dependencies can carry hidden security vulnerabilities.
How Snyk Works
Snyk scans your codebase and its dependencies. It compares each package against a large database of known vulnerabilities. When it finds an issue, it tells you exactly which line of code is affected and what you can do to fix it.
It integrates directly into your development workflow. Developers receive security alerts right inside their code editor or in a pull request. This means security issues get caught and fixed before the code ever makes it into production.
Why This Matters for Neobank Security Audits
In a security audit, auditors often check whether your development process includes security testing. With Snyk, you can demonstrate a comprehensive history of every vulnerability discovered and subsequently resolved in your codebase.
This is known as “shift-left” security — moving security checks earlier in the development process. It is far less expensive and easier to fix issues in development rather than after your app has already launched.
According to the OWASP API Security Top 10, API vulnerabilities are among the most critical risks facing modern applications — exactly the kind of threat Snyk helps you address at the code level before it ever reaches production.
Infrastructure as Code Security
Snyk also inspects your infrastructure configurations. If your cloud setup has a misstep — like an accidentally public storage bucket — Snyk catches it before it turns into a breach.
Best for: Development teams at neobanks and fintech companies that want to bake security into their coding process.
Key features:
- Open source vulnerability scanning
- Container security
- Infrastructure as Code scanning
- Developer-friendly integrations
App #6 — Aikido Security
A Newcomer Making Big Waves in Fintech Security Auditing
Newer than some of the other tools on this list, Aikido Security has quickly won over fans among fintech startups and emerging neobanks.
Why? Because it combines multiple security scanning tools into one simple, affordable platform — without the endless hassle of juggling separate tools.
Everything in One Place
Rather than using five different tools for code scanning, cloud security, compliance and dependency checks, Aikido pulls them all together. For smaller and mid-size neobanks, that helps cut costs and complexity significantly.
Aikido scans your code repositories, cloud environments, containers and APIs. It then gives you a unified view of all your security risks, ranked by severity.
Smart Risk Prioritization
Another great thing about Aikido is how it prioritizes vulnerabilities. Security issues are not all equally threatening. Aikido uses context to determine which vulnerabilities are actually reachable by an attacker and which are theoretical risks.
This means your security team spends time on the issues that actually matter — not chasing false alarms.
Audit-Ready Reports
Aikido also produces clean, professional security reports that can be shared with auditors, investors or regulators. For a growing neobank trying to build trust with partners and customers, this level of transparent reporting is invaluable.
Best for: Fintech startups and mid-size neobanks looking for an all-in-one, cost-effective security audit solution.
Key features:
- Unified security dashboard
- Smart vulnerability prioritization
- Cloud and code scanning
- Audit-ready reporting
How These 6 Apps Work Together
You don’t have to pick just one. The strongest security audit programs combine several tools that work well together.
Here’s a simple way to visualize how these apps fit in concert:
LAYER 1 — Code & Development
→ Snyk (scans your code and dependencies)
LAYER 2 — Application & API Testing
→ Burp Suite Professional (tests the app and APIs for vulnerabilities)
LAYER 3 — Infrastructure & Cloud
→ Qualys Cloud Platform (monitors your cloud environment)
→ Aikido Security (covers cloud, code, and containers)
LAYER 4 — Event Monitoring & Threat Detection
→ Splunk Enterprise Security (analyzes logs and triggers threat response)
LAYER 5 — Compliance & Audit Preparation
→ Vanta (automates compliance and prepares audit evidence)
Together, these tools cover every layer of your fintech security stack. From the first line of code to your final compliance report, you have full visibility and control.
Security Audit Mistakes Neobanks Keep Making
Even with great tools, things can still go wrong. Here are some things to avoid:
Running audits too infrequently. Once a year is not enough. Threats evolve constantly. Monthly or continuous auditing is the new standard.
Ignoring API security. APIs are the lifeblood of every neobank. To leave them untested is like leaving your front door unlocked.
Not involving developers. Security audits shouldn’t just be a thing for the security team. Developers need to be involved, especially with tools like Snyk.
Skipping third-party vendor audits. If your neobank relies on third-party services, their security is really your security. Audit your vendors too.
Not acting on findings. Your audit is only as good as what you do with the information you collect. Set up a clear remediation plan and stick to it.

FAQs — Neobank and Digital Wallet Security Audits
Q: How often should a neobank conduct a security audit?
At the very least, neobanks ought to be doing a full security audit at least once per year. But with tools like Qualys or Splunk, continuous monitoring becomes an option and is recommended. Additionally, many compliance rules mandate quarterly vulnerability scans.
Q: What is the difference between a vulnerability scan and a penetration test?
A vulnerability scan is automated. It scans your system for known vulnerabilities. A penetration test goes a step further — a security expert actively attempts to break in, just as an actual attacker would. Tools such as Burp Suite are used in pen testing.
Q: Do small neobank startups actually need all six of these tools?
Not necessarily. A startup can begin with one or two tools and work its way up. Aikido Security is great for startups because it does a lot of things in one platform. Snyk also has a free plan for small teams. Specialized tools can be added as you grow.
Q: What are the most important compliance frameworks for digital wallets?
PCI DSS is the most important for digital wallets as they process payment card data. SOC 2 matters when it comes to building trust with business clients. If you serve users in Europe, GDPR matters. Your particular needs will vary depending on where you operate.
Q: Can these tools stop all cyberattacks?
No tool can ensure 100% protection. But applications like these shrink your attack surface significantly and can greatly improve the speed at which you detect and respond to threats. The goal is to make it as difficult as possible for attackers and as easy as possible for your team to catch them.
Q: What is the most pressing security risk for neobanks today?
API vulnerabilities are now one of the most prominent threats to neobanks and digital wallets. Because neobanks are built entirely around APIs, a single poorly secured endpoint can lead to the exposure of millions of users. This is why tools like Burp Suite and Snyk are so critical.
Wrapping It All Up
Security audits are not a choice for neobanks and digital wallets. They are a legal requirement, a trust signal for customers and your best protection against expensive breaches.
The good news: you don’t have to do it all yourself. The six smart apps we discussed here — Qualys, Burp Suite Professional, Vanta, Splunk Enterprise Security, Snyk and Aikido Security — each make a distinctive contribution to making your security audits faster, smarter and more valuable.
Whether you’re a fast-growing startup or an established neobank, there’s a mix of these tools that is right for your needs and your budget.
Start where you are. Add the right tools. Create a security culture where audits are taken seriously — not just when regulators come calling, but every single day.
Because in fintech, trust is everything. And trust starts with security.
