Why Guardsquare?

SensorTower’s State of Mobile 2026 report showed there were 149 billion new mobile application downloads last year and in-app purchases grew to $167 billion (10.6% growth YoY). As mobile apps become indispensable tools for many industries, securing those apps becomes a line-of-business concern.

Guardsquare is the leader in mobile application security, with more than 1000 customers in over 100 countries and 6+ billion protected users (both Android and iOS). Guardsquare’s platform combines purpose-built testing (AppSweep), multi-layered protections (DexGuard, iXGuard), continuous threat monitoring (ThreatCast), and API protection (via app attestation capabilities) for comprehensive security across all phases of the mobile app lifecycle.

The Guardsquare platform offers:

Guardsquare helps meet security compliance requirements

Guardsquare helps customers maintain regional regulatory requirements and privacy laws, as well as industry certifications and standards. For clients in highly regulated industries, security incidents can have serious repercussions. In the banking industry, fraud attacks can cause financial losses, exposure of sensitive data, regulatory fines, legal costs, as well as brand damage. In the healthcare industry, an insecure mobile health (mHealth) app could have any of the aforementioned risks as well as patient safety.

Guardsquare helps organizations protect the integrity of their mobile apps, enabling them to meet compliance requirements, safeguard their business, and protect end-users from malicious actors. This includes helping companies pass internal/external pentesting and protecting their apps against evolving threats.

• Financial services: An SDK provider for iOS and Android payment apps needed to comply with Payment Card Industry (PCI) SDK 3DS Security Standards. Guardsquare helped ensure that its SDK was obfuscated and encrypted to achieve and maintain PCI compliance.
• Healthcare: A Software-as-Medical Device (SaMD) developer based in the US needed to stay on top of the evolving regulatory requirements for the apps they provide to their clients. Guardsquare helped the developer meet FDA compliance standards.
• Telecom: A leading telecommunications provider in Switzerland needed comprehensive protection for their mobile apps to pass annual comparative pentesting evaluations required in their region. Guardsquare’s guided workflow helped them seamlessly release a fully protected application to their test systems on the first day.
• Banking: A prestigious Brazilian bank needed robust code obfuscation that would help secure sensitive customer data processed by and stored in their mobile apps. Guardsquare provided comprehensive code protection that enabled them to pass internal mobile app pentests and meet compliance requirements for Lei Geral de Proteção de Dados (LGPD), a Brazilian data protection law.

Guardsquare ensures mobile app integrity and protects sensitive IP

Our engineers were excited to see the breadth of advanced protection DexGuard and iXGuard offer. On top of the control flow obfuscation, data encryption, and other code-hardening techniques we desperately needed, we also layered this static protection with the RASP capabilities to protect against attacks at runtime.
— Mobile Front-End Lead, Southeast Asian hypergrowth FinTech company

Guardsquare helps customers protect the integrity of mobile apps and SDKs through DexGuard (Android) and iXGuard (iOS). Unlike wrapper solutions with only a single point of failure, DexGuard and iXGuard are compiler-based code protection tools that interweave multiple layers of advanced static and dynamic protection into your application code. Here are a few key ways we accomplish this:

Preventing apps from running in an unsafe environment

• Ensure environment integrity: The aforementioned mobile payment app SDK provider needed to ensure its software wouldn’t work on a compromised device. Although an app running on a rooted/jailbroken device or emulator does not pose a direct threat, it is often the prerequisite for attackers to execute their attacks. By leveraging multiple RASP checks, the customer was able to maintain the environmental integrity their SDK runs on.

Preventing reverse engineering attacks

• Maintain app and code integrity: A top-50 largest US bank used DexGuard to secure intellectual property inside its Android apps. DexGuard’s static and dynamic protection features prevent threat actors from being able to easily understand and modify their app’s logic and flow to gain access to sensitive assets embedded in the code.

Guardsquare prevents potential revenue loss

We were losing control of our apps. When we discovered that we were losing money due to fraud, we knew we needed to improve our security, and quickly. We realized that we could no longer securely protect our apps by ourselves.
— Information security expert, Leading digital wallet provider

Insufficiently secured mobile applications carry risks that can result in direct and indirect financial losses. This can range from IP theft, to transaction fraud, to regulatory fines, all the way up to lost business and brand damage. A recent survey of mobile app developers and security leaders showed that nearly two-thirds (65%) reported customer churn or uninstalls as a result of security issues within the last year.

Let’s look at some case studies that demonstrate how Guardsquare helps to protect customer revenue.

Preventing fraud, IP theft, and piracy

Guardsquare’s combination of mobile app testing and protection prevents fraud attacks and intellectual property theft. Some customer success stories include:

• Block financial fraud: A mobile wallet app provider (with more than 2 billion recorded financial transactions across its Android and iOS apps) was losing money due to in-app bonus fraud. The company was able to leverage Guardsquare’s API call hiding and app integrity check capabilities to effectively block these fraud attacks.
• Protect brand reputation: A Southeast Asian financial services provider experiencing record growth—handling billions of financial transactions annually—found that their DIY approach to security was causing performance issues. They needed to make sure that their mobile apps were highly secure without degrading the user experience. Guardsquare’s platform helped them achieve this and fulfill its promise of providing a user-friendly and secure banking experience.
• Prevent modded/cloned apps: The maker of a popular video and photo imaging app was targeted by pirates who were decompiling, modifying, and repackaging their insecure premium mobile app. These unauthorized clone apps were being distributed to third-party sites, where unauthorized users could use premium services for free, which significantly impacted the customer’s bottom line. Guardsquare was able to sink these pirates with a layered combination of static and dynamic protections.
• Stop content/service piracy: A pay TV and streaming media company in Latin America (with mobile apps used by more than 10 million customers across 11 countries) was experiencing exponential growth. They needed mobile app security beyond the basic content protection techniques like encryption and Digital Rights Management (DRM). Bad actors were exploiting client-level vulnerabilities and bypassing premium restrictions to access streaming services for free. Guardsquare’s platform helped the customer scan their code for security issues, protect apps with multiple layers of code obfuscation and polymorphic RASP checks, and monitor threats in real-time post-release.

Protecting community health on social media and mobile gaming apps

When we detected hundreds of bot attacks on our platform, we realized that we needed to improve our security posture immediately. [...] This is detrimental to the platform’s health as the engagement level enables them to commit different kinds of fraud.
— CTO, Emerging social media platform

The health of the community in social media and gaming apps is crucial; it can make or break a business. Guardsquare preserves user-base health by preventing attackers from being able to execute bot attacks. It also prevents potential game cheaters from tampering with the code. Threat monitoring enriches detection of malicious activity by providing real-time visibility into how a mobile app is being used.

• Prevent coordinated bot attacks: The maker of an emerging social media app was detecting hundreds of bot attacks. Attackers were using a variety of methods to hijack the app’s content discovery feature and then spread misinformation and controversial content. Guardsquare’s code hardening and RASP capabilities successfully prevented malicious users from executing these attacks.

Optimizing operational efficiency

Guardsquare provides a complete, out-of-the-box mobile app security strategy. This gives our customers the assurance of mobile-native security across the entire software development lifecycle (SDLC) – allowing them to focus on future releases and the growth of their company.

• Out-of-the-box solution: A European FinTech startup company needed to protect its mobile app and meet regulatory compliance requirements–without slowing down release cycles and while keeping its overhead low. The company was impressed by Guardsquare’s competitive prices as well as its ability to integrate DexGuard into the early stages of the development cycle to ensure a secure app and launch on schedule.
• Maintain business agility: An automotive software company was manually helping their customers implement Android app protections against reverse engineering and cloning attacks. Guardsquare’s code hardening and RASP checks helped them unburden their customers from the worries of homebrewed security and gain greater peace of mind.

Guardsquare provides protection without compromise

DexGuard and ThreatCast have made [the app] more secure, faster, and better for users.
— Founder and developer, AI tool provider

Many organizations question whether mobile app security will negatively impact development cycles, app performance, or user experience. Guardsquare understands that security isn’t a tradeoff – it’s an equally essential factor among other line-of-business drivers.

User-friendly and straightforward implementation

Ease of use and implementation: A top Australian bank (one of the 30 largest in the Asia-Pacific region) needed to deliver new iOS and Android apps to the market on a strict deadline, and still meet all regulatory and compliance requirements. The company was able to seamlessly implement protections with little-to-no additional overhead on the development team, while simultaneously passing the required pentests and meeting their app publishing deadlines.

Command-line tools that don’t need to access or alter source code

Safeguard your source code: DexGuard and iXGuard are on-prem, post-build command-line tools that can run directly on an app developer’s local machines. This helps ensure the security and privacy of your mobile application’s source code. The aforementioned US-based bank concerned with potential IP theft, credential harvesting, and tampering was able to leverage Guardsquare’s products without risking its app’s source code.

Protection that doesn’t hinder end-user experience

Protection that optimizes UX: DexGuard reduces download size by 50% and a mobile app’s installation size by more than half, even with additional new features. The previously cited South-Asian digital wallet provider who managed to prevent financial fraud was also pleasantly surprised to discover that Guardsquare improved the performance and speed of its apps. Similarly, the Australian bank concerned with improving app security without sacrificing end-user experience achieved both goals with Guardsquare.

Guardsquare helps you continuously improve security

The protection report Guardsquare offers allows us to easily and continuously evaluate, improve, and validate the protection configurations of our applications early in the development lifecycle.
— CISO, Top-10 Pakistani commercial and retail bank

Guardsquare’s protection report feature helps developers confirm and validate their security configurations, allowing them to apply optimal security to their mobile apps. By implementing both RASP checks and real-time monitoring, developers can use insights about dynamic client-side threats to inform future builds. This telemetry can also be sent to other systems, such as performance and crash analytics, SIEM, SOC pipelines, and anti-fraud (i.e., QRadar, Splunk) for holistic security integration.

Stay on top of the ever-evolving threat landscape

Continuous security improvement: The aforementioned Southeast Asian hypergrowth FinTech company that chose Guardsquare to help protect its brand integrity, also made full use of ThreatCast monitoring for visibility of their apps in production. By enriching their existing SIEM system with real-time insights, they were able to maintain a 360° view of the threats their apps are facing and improve collaboration between their red and blue teams, as well as governance and risk stakeholders.
