The perimeter no longer exists. Your code must defend itself.
THE 3 STRUCTURAL RISKS OF THE SOFTWARE LIFECYCLE
Intellectual-property theft
Real-time data extraction
Incidents demanding immediate resolution
PROTECTION DESIGNED BY THOSE WHO KNOW HOW TO BREAK IT
There was a time when protecting an application meant securing its perimeter. That time is over. Today, your applications run on devices you don’t control, in environments you don’t master, in the hands of people whose intentions you cannot verify. The perimeter no longer exists. The only protection that matters is the one that travels with your code.
QShield is Quarkslab’s proprietary technology suite. It is not the product of a conventional security vendor — it is the fruit of the same offensive research that powers QRedTeam and QLab. In other words, QShield is designed by experts who know exactly how an attacker would go about breaking your code. And who built their protection accordingly.
4 PROTECTION MODULES
QShield offers a suite of highly adaptive protections covering the entire software lifecycle — from development to deployment. Each module is independent and can be combined according to your threat model.
01 SOFTWARE PROTECTION
- Protect your applications against static and dynamic analysis with more than 30 obfuscation schemes and real-time RASP protection. Every build is unique — diversification via a user-defined random seed. Granular control through a YAML file or in-code comments.
- C · C++ · Java · Kotlin · Objective-C · Swift · 30+ obfuscation schemes · real-time RASP · build diversification.
Static analysis (obfuscation)
- 30+ code & data obfuscation passes
- diversification (every build is unique)
- granular control via YAML file or annotations
- controlled performance/security ratio
Dynamic analysis (RASP)
- root/jailbreak detection
- debugger & emulator detection
- analysis-framework detection
- actions triggered on detected anomaly
02 Keys protection
- Protect your cryptographic keys against extraction and side-channel attacks, with no Secure Element or TPM. Each implementation is unique per client — no sharing across instances. Proven resistance to DCA/DFA attacks. The world’s first SBMP-certified product for a white-box cryptography component.
- AES · RSA · ECC · per-client unique white-box · no SE or TPM · SBMP-certified · anti-DCA · anti-DFA.
Supported algorithms
- white-box implementations of common algorithms
- mobile-payment & entertainment use cases
- keys at rest and at runtime
Robustness & certification
- DCA/DFA resistance proven by audit
- world’s first SBMP-certified product (white-box crypto)
- unique implementation, not shared across clients
03 Data protection
Data vault: encryption bound to the device’s identity.
- Secure storage of sensitive data (tokens, credentials, passwords, configurations) with a unique per-device fingerprint. Even if the protection is lifted, the application cannot be repackaged. Multi-platform abstraction layer, integration through simple C/C++ API calls.
- Unique per-device fingerprint · C/C++ libraries · multi-platform · simple API · anti-repackaging
Data protection
- tokens, credentials, API keys, configs
- data always stored encrypted
- decryption only on an authorized device
Integration
- C and C++ libraries available
- multi-OS abstraction (no reimplementation)
- project integration via API calls
04 Environment Checks
- Real-time visibility into the security of your fleet (IoT, desktop, mobile). Anomaly detection: debuggers, reverse-engineering tools, emulators, code/data tampering. Security policies adapt dynamically to the detected risk profile (Moving Target Defense)
- Real-time · IoT · Desktop · Mobile · Moving Target Defense · OTA updates · large-scale fleet
Anomaly detection
- debuggers & reverse-engineering tools
- emulators & suspicious environments
- code/data tampering
Adaptive defense
- flexible, dynamic defense strategy
- countermeasures tailored to the client risk profile
- OTA patches — continuous security hygiene
WHAT YOU GET OUT OF IT
Code that defends itself, everywhere
Protection that depends on neither your infrastructure nor your network. QShield protects where you no longer are — on the end user’s device, in your customer’s environment, on a system you no longer control.
Your intellectual property stays yours
Proprietary algorithms, models, sensitive business logic: QShield makes their extraction structurally impossible for any attacker, even an advanced one.
Protection that stands the test of time
QShield is not a blacklist of known signatures. It is a protection architecture designed to withstand attackers who adapt — because it was conceived by people who adapt themselves.

THE WORLD’S FIRST SBMP-CERTIFIED PRODUCT FOR A WHITE-BOX CRYPTOGRAPHY COMPONENT
All QShield components have been certified through the rigorous SBMP (Software-Based Mobile Payment) evaluation process by an independent third-party laboratory. This certification guarantees a high level of robustness — essential for mobile-payment applications — and significantly reduces certification timelines for payment-service providers.
It also applies to the media and entertainment sectors and to software intellectual-property protection.
