Bionano Increases Compliance with Regulations Using Jscrambler
Jscrambler provided Bionano with the most resilient JavaScript protection and satisfied the regulatory requirements for code protection.

Overview

Bionano is a biotechnology company specializing in genome mapping and analysis and can enable researchers and clinicians to reveal answers to challenging questions in biology and medicine. Bionano’s mission is to transform how the world sees the genome through optical genome mapping (OGM) solutions, diagnostic services, and software. Bionano also offers an industry-leading, platform-agnostic genome analysis software solution and nucleic acid extraction and purification solutions using proprietary isotachophoresis (ITP) technology.

Challenge

Each time Bionano engages in an enterprise-level clinical environment, they are subjected to a rigorous security audit. By interacting with many security organizations globally, they gained an in-depth understanding of what these security organizations expected.

Bionano chose Node.js as its visualization platform as it facilitated reaching the widest audience of users (macOS, PC, and Linux). It also provided an extensive array of visualization tools such as D3js, ThreeJS, and ChartJS that allow the creation of rich interactive genomic maps for customers to explore. Bionano software is free to encourage the use of Saphyr-generated data. Anyone can download and start their own Bionano Access Server. Bionano needed a way to protect their downloaded client and server-side JavaScript logic to satisfy multiple security regulations

Solution

The Bionano system itself is designed not to hold protected private information (PPI), so the company did not face significant liability to be concerned with. However, as an extra precaution and to be as compliant as possible, the company understood the need for JavaScript code protection. In search of the optimal solution, Bionano tested some JavaScript obfuscation solutions but found out that these could be easily reversed or debugged. Jscrambler was the only solution that passed all their tests and which they could not reverse.

This implementation of Jscrambler was greatly derived from the need to comply with several different regulatory requirements. In the specific case of Bionano, the regulations that apply to their clinical customers vary depending on their local principalities. Some regulations, like ISO 27001 and 27002, specifically require source code protections, while others have more general data protection and/or encryption requirements.

Jscrambler does not solve all of Bionano’s security concerns, but it provides what the company needs to protect the source code enough to satisfy all regulations in that regard. Then, there’s also the matter of protecting intellectual property. Bionano’s system provides comprehensive genomic variation data for review.

Jscrambler Helps Neobanks Protect JavaScript

Posted on July 24, 2026 by -

How Neobanks Strengthen Client-Side Security with Jscrambler
Several of the world’s leading neobanks and challenger banks turned to Jscrambler to strengthen the security of their web applications as digital channels became central to customer experience and revenue growth. Operating in highly regulated environments and handling sensitive financial data at scale, these institutions needed to protect their client-side JavaScript from reverse engineering,
tampering, and logic abuse.

Overview

Neobanks defy traditional banking by betting everything on digital and delivering customer-centric services for payments and money management. Today, over 90% of consumer interactions with banks are digital. Neobanks typically release new features more frequently, often every few weeks, while traditional banks tend to take several months to bring similar innovations to market. As a result, user satisfaction ratings for neobanks in the US (63%) are higher than those of traditional banks (55%).

Neobanks’ technological flexibility stems from investing in cloud-based infrastructure and advanced web and mobile applications built with modern JavaScript frameworks such as React Native. With this approach, they cut product development cost and time, paving the way for rapid iteration and innovation. This is greatly aided by relying on third-party integrations rather than developing every piece of code in-house. In software development, pursuing agility and speed often means widening security gaps. Despite JavaScript’s numerous advantages, neobanks must be aware that client-side JavaScript is exposed and can be used to launch attacks, including intellectual property theft, code tampering, application abuse, and data exfiltration. Unless protected with an enterprise-grade solution, this exposed JavaScript poses a key business threat.

Challenge

In recent years, several neobanks from North and South America, Europe, and Asia have approached Jscrambler due to significant security challenges. With web and mobile apps built with JavaScript — and a strong adoption of cross-platform frameworks for mobile development like React Native and Ionic — security teams understood early on that client-side logic would pose a significant security risk. There was a high likelihood of having to run sensitive logic on the client-side, so it became paramount to ensure that this logic would be concealed using the most potent and resilient technology available today. It was also mandatory to ensure that automated reverse-engineering tools would always fail to reverse the concealed code, while making it extremely unfeasible for attackers to achieve it manually. As these neobanks’ apps would handle sensitive services, another key challenge was ensuring that malicious actors couldn’t tamper with the code. JavaScript had to react in runtime to mitigate these attacks. And since both the web and mobile apps would handle sensitive data, such as credentials, personally identifiable information, and financial details, an additional pre-eminent requirement was to ensure that JavaScript couldn’t serve as a gateway for attackers to steal user data.

With each neobank offering multiple applications to their end customers, it was also essential to ensure that JavaScript protection would integrate seamlessly with their CI/CD and integration testing. Finally, in such a heavily regulated sector, another significant challenge was achieving compliance with regulations such as PSD2, NIST, the PCI DSS requirements 6.4.3 and 11.6.1, and specific requirements for operation like those of Bank of Brazil, for example, with a special focus on client-side attacks.

Solution

To meet the highest standards for JavaScript protection, these neobanks sought a holistic solution that would fit their processes and scale. Jscrambler presented a mature, proven client-side security product suite that, like noobanks themselves, is defined by continuous innovation.

The first step towards securing JavaScript was Jscrambler’s polymorphic obfuscation. With this critical security layer, all of the source code of neobanks’ apps was concealed beyond possible recognition. Jscrambler’s set of the most potent and resilient transformations was key to guaranteeing cutting-edge obfuscation. Its inherent polymorphism ensured that each new code deployment would be completely different—an extra line of defense against reverse-engineering attempts. For example, one of the banks had their fingerprinting script collect information from the session/browser, and wanted to protect it as it was exposed. Jscrambler provided the neobank with advanced polymorphic obfuscation to allow it to serve its fingerprinting script (practically unique) in each user session.

Security teams implemented critical OWASP recommendations, including the OWASP Mobile Top 10, which highlights that “to prevent effective reverse engineering, you must use an obfuscation tool” and that “the app must be able to react appropriately at runtime to a code integrity violation.” At the same time, they ensured compliance with PSD2 mandates, including transaction monitoring and strong customer authentication, as well as PCI DSS v4 requirements to safeguard payment pages and credit card data from client-side tampering. In addition, they aligned their client-side security measures with NIST guidelines, strengthening code integrity, runtime protections, and risk management practices in line with industry-standard cybersecurity frameworks. Jscrambler mostly worked with Security Engineers at these banks who were well aware of the problem and the required steps for solving it. After the initial setup of the Jscrambler instance, it took on average 2 weeks and 2 meetings with Jscrambler’s engineers to integrate Jscrambler seamlessly into their CI/CD pipeline. From there, Jscrambler became an automated part of their application build process.

Top Jscrambler Features and Capabilities

  • Polymorphic obfuscation
  • Anti-Tampering
  • Compliance with financial regulations and standards

Results

Securing JavaScript code requires awareness of the threats posed by exposing important logic on the client-side. Neobanks have had this pain from the very start of the business, as their main assets depend on it. By opting for Jscrambler’s proven JavaScript protection technology, product teams met their primary requirement: integrating a code protection solution seamlessly into their CI/CD. Now, these neobanks deploy secure code to production, knowing that each build has a fresh set of the most potent and resilient JavaScript protection available today. Jscrambler helped neobanks rethink key and critical data management in the applications, moving keys into JavaScript and applying Jscrambler Code Integrity to protect them effectively.

Through advanced obfuscation techniques, anti-debugging protections, and tamper detection, the solution prevented key theft, code tampering, and reverse engineering, ensuring the web application remained protected even when running on the client side. For management, safeguarding their applications’ source code from reverse engineering and tampering translates into a clear competitive advantage. Investors also recognized the reduced liability associated with exposed JavaScript in neobanking; with Jscrambler, these banks strengthened their position in future funding rounds and earned the trust of millions of potential customers. In a results-driven industry, the outcome was unequivocal: 0 integration issues, 0 successful attacks on JavaScript code.

How Jscrambler Helps dotConnect Deliver Secure Banking Apps

How Jscrambler Helps dotConnect Deliver Secure Banking Apps
Jscrambler successfully protects and secures the source code of the banking applications.

Overview

dotConnect is a fintech with the vision to empower financial institutions to provide their clients with a platform that delivers an exceptional digital banking experience. Via cloud-native solution architecture that is built for scale and resilience, dotConnect allows banks to accelerate their digital transformation and automation journeys. This enables these banks to provide a modern, customer-focused digital experience, reduce operational service requirements, and achieve low and predictable operational costs while also guaranteeing flexible integration with new and legacy banking systems using a decoupled approach.

Challenge

Today, 73% of all consumer interactions with banks are done digitally. And when it comes to banking, security is a prime directive. When asked about the most important attributes when choosing a bank, 82% of consumers say, “ensures my transactions are safe/secure.” Being aware of how security is one of the key drivers in the ongoing banking digitalization, dotConnect wanted to ensure that they were developing secure banking apps. This meant covering every inch of the attack surface.

Regarding web and hybrid mobile banking apps, one key security challenge is protecting the JavaScript code, which can be targeted by reverse-engineering, tampering, and injection attempts. This layer of protection is essential to reduce exposure to data exfiltration and transaction fraud, which can originate from client-side attack vectors.

Solution

The answer to dotConnect’s challenges in terms of source code protection was the cutting-edge technology provided by Jscrambler. Both founders had previously used Jscrambler in a previous solution within the banking sector a few years ago. So, when embarking on this new venture, they revisited the market to compare vendors and found that Jscrambler was still the market-leading solution in this sector. Thus, it was the obvious choice. Because dotConnect had to ensure maximum protection of the JavaScript source code, its team decided to combine two of Jscrambler’s most effective clientside security layers: JavaScript Obfuscation and Self-Defending.

Jscrambler’s Polymorphic JavaScript Obfuscation includes several different techniques that transform the original source code into a new version that is extremely hard to understand and reverse-engineer while keeping its original functionality. Included in this layer is Jscrambler’s Code Hardening feature, which provides up-to-date protection against all reverse-engineering tools and techniques.

dotConnect uses Jscrambler Self-Defending, a security layer that adds integrity checks and other runtime defenses that prevent attackers from debugging or tampering with the code. As such, if anyone tries to debug the protected banking app at runtime, the app will immediately break. Likewise, if an attacker tries to modify the code to dynamically understand its logic at runtime, the application will break to stop the attack. This advanced runtime protection reduces the attack surface to data exfiltration attacks by making it much harder for attackers to understand how the software works and plan/ automate these attacks

“When you have a financial product out in the public domain, you’re a prime target for attackers.”
Mohamed Gamil

CEO & Founder of dotConnect

“The protection layer that Jscrambler provides is very, very difficult to interpret, break, or bypass.”

Top European Airline Ensures Stellar Client-Side Protection with Jscrambler
Jscrambler’s advanced script and form security protection ensures sensitive form data is protected and malicious scripts cannot load.

Overview

This European airline is a global leader in air transportation that operates an extensive flight network connecting Europe to the world through its hubs in European capitals. With over 70,000 dedicated employees and a commitment to diversity, the airline serves millions of passengers across 300 destinations in 120 countries. A large portion of these passengers uses the company’s websites and mobile apps to book flights, check in online, chat with customer service, and redeem loyalty points.

Challenge

The client’s decision to search for client-side protection technology was initially triggered by a credit card data breach at another airline.

Before implementing Jscrambler, the client relied on more traditional security processes that involved checklists and paperwork. However, this manual approach left room for vulnerabilities: “We had security people who could decompile libraries, but they were usually too busy to do it.”.

When the client’s team needed to go fast and add new scripts, innovation sometimes took priority, which meant they would find workarounds to circumvent the documentation-heavy process, leaving them potentially open to attack.

Solution

In search of a comprehensive JavaScript monitoring and protection solution, the client considered various factors, including features and cost. Jscrambler stood out as the only solution that met their security requirements.

The client was particularly impressed by Jscrambler’s Form Fencing feature, which offers fine-grained behavioral control over third-party tag access to form data based on high-level assumptions and user-defined rules. Unlike other solutions, Jscrambler allowed the airline to authorize or block scripts individually.

The company put Jscrambler’s Webpage Integrity solution to the test in multiple Magecart attack scenarios. They ran dozens of tests to see if the solution could detect if content was added, modified, or removed from pages illicitly (DOM tampering), if form events were poisoned, or if data was exfiltrated to a drop server. Jscrambler’s technology passed every single test with flying colors and outperformed all the other available solutions. Adding Jscrambler to a page had little to no impact on its performance.

“Other solutions allow you to monitor cross-site scripting or visit CSP policies, but that’s all they do. They won’t protect forms. They won’t ask, “Is this sensitive data? Yes or no?” For us, Jscrambler was the best platform because they do it all.”
Information Analyst and Product Owner Mobile at Top European Airline

“With most companies, you buy a product, you get support for one or two months, and then you’re on your own. But with Jscrambler, we meet regularly twice a month. We know when new features are coming, even if they haven’t been released yet because they’ll tell us about them on our call and ask us what we think. It’s a nice dialogue to have. You really feel the personal touch. Jscrambler’s customer support is definitely a big plus.”
