It's not just software. Meet the Hardware-Backed Keystore: a digital fortress built directly into the silicon of your device. 🛡️<br> Unlike software that can be hacked, this system uses dedicated, tamper-resistant hardware - Secure Enclave on Apple devices or TEE/StrongBox on Android. Their purpose is to:<br> ✅ Store cryptographic keys in tamper-resistant hardware<br> ✅ Perform cryptographic operations without exposing keys to the main OS<br> ✅ Provide hardware-level attestation and integrity verification<br> ✅ Resist both software and physical attacks<br> This architecture ensures that even if the device's operating system is compromised, sensitive cryptographic material remains protected. Essential for enterprise security, mobile payments, and any application requiring strong authentication.<br> Our data shows that almost every device has this feature available. Lack of this feature might imply fake or unprotected device.</p> <p>📈 Track your app's security trends in real-time on our new portal: <a href="http://my.talsec.app" rel="noopener noreferrer">http://my.talsec.app</a> <br> 🛡️ Not protected yet?
