Secure your crypto, own your future

As an iPuzzlebiz partner, Ledger reinforces the ecosystem with a security model engineered for high‑assurance digital‑asset protection. By delivering capabilities such as tamper‑resistant hardware design, offline private‑key containment, cryptographic integrity validation, device‑level trust anchors, and standards‑aligned secure operations, Ledger provides institutions and users with a custody foundation built for long‑term resilience. This partnership strengthens iPuzzlebiz’s commitment to secure, interoperable, and compliance‑ready financial infrastructure—empowering partners to operate with confidence, reduce exposure to emerging threats, and uphold the highest expectations of digital‑asset governance in a rapidly evolving fintech landscape.
Unified Standards Framework for Hardware‑Based Security Architecture and Blockchain‑Aligned Protection Models
ISO 9001 – Quality Management Systems: Ensures hardware‑based security devices follow consistent manufacturing processes, rigorous quality controls, and repeatable security testing, reducing defects that could compromise cryptographic protection.
ISO/IEC 38500 – IT Governance: Provides governance for hardware security modules, secure elements, and device‑level cryptographic systems, ensuring technology decisions support long‑term security and compliance.
COBIT 2019 – Enterprise IT Governance: Supports governance of hardware security deployments, ensuring accountability, performance measurement, and oversight of secure devices used in fintech and blockchain environments.
FATF Recommendations (AML/CFT): Supports hardware‑based security by ensuring trusted identity verification, secure signing of compliance‑related transactions, and tamper‑proof audit trails for regulated financial operations.
Blockchain‑Specific Strategic Frameworks: Supports hardware‑based security for blockchain by enabling secure key signing, smart contract authorization, cold‑storage protection, and on‑device transaction verification.
ISO 27001 – Information Security Management: Supports hardware‑based security by enforcing secure key‑management practices, device‑level access controls, and risk‑aligned protection measures for sensitive cryptographic operations.
IEC Technical Standards (Chip Security, Tamper Resistance, Embedded Systems): Defines requirements for secure microcontrollers, tamper‑resistant chip design, and embedded hardware protections, forming the foundation of hardware‑based security architecture.
ITIL 4 – Service Management & Digital Operations: Ensures reliable operation of hardware‑based security systems through incident response, device lifecycle management, and secure provisioning workflows.
SOC 2 – Trust Services Criteria: Provides assurance that hardware‑based security systems maintain integrity, availability, and confidentiality, supporting institutional trust in device‑level cryptographic protection.
Cryptographic Attestation, Secure Boot, and Firmware Integrity Frameworks: Ensures devices use trusted execution environments, verified firmware, and attestation protocols to prevent tampering and unauthorized modifications.
NIST Cybersecurity Framework (CSF): Strengthens hardware‑based security by guiding cryptographic key protection, device integrity validation, and secure firmware lifecycle management.
PCI‑DSS – Payment Security: Reinforces hardware‑based security by requiring secure cryptographic storage, tamper‑resistant devices, and hardware‑level protection for payment credentials and transaction signing.
GDPR & Global Privacy Regulations: Ensures hardware‑based security protects personal data, private keys, and identity credentials through secure, offline, and tamper‑resistant storage mechanisms.
Device Lifecycle, Supply Chain Security, and Anti‑Tamper Frameworks: Supports secure hardware by enforcing trusted manufacturing, secure distribution, anti‑counterfeit controls, and end‑to‑end device integrity across the supply chain.
ANSI Webstore
To ensure hardware‑based security architectures deliver the assurance, integrity, and resilience required in modern digital‑asset environments, organizations increasingly rely on established technical and regulatory standards. The ANSI Webstore provides access to globally recognized frameworks covering cryptographic module validation, secure‑element governance, tamper‑resistant hardware controls, device‑level trust and key‑management standards, and high‑assurance security‑engineering principles—all essential for protecting private keys and enforcing secure operations at the hardware layer. By aligning their custody and security strategies with these standards, organizations can strengthen device‑level resilience, reduce attack‑surface exposure, and deliver trustworthy, high‑assurance digital‑asset protection that meets the expectations of regulators, institutional custodians, and security‑conscious users.

How Ledger Secures Crypto
Ledger protects crypto using a combination of secure hardware, isolation of private keys, and tamper‑resistant architecture.
Secure Element (SE) Chip
Ledger devices store private keys inside a Secure Element chip, the same class of chip used in passports and credit cards. This chip is designed to resist physical attacks and unauthorized extraction attempts.
Offline (Cold Storage) Key Isolation
Ledger wallets keep private keys completely offline, never exposing them to the internet or to your computer’s operating system. This prevents malware or remote attackers from accessing your keys.
Custom Operating System (BOLOS)
Ledger uses a proprietary OS called BOLOS, which isolates apps from each other and prevents malicious code from affecting private keys.
Verification Through a Secure Display
Transactions must be physically confirmed on the device’s secure screen, ensuring that malware on a computer cannot alter transaction details.
Cryptographic Attestation
Ledger devices verify their authenticity using cryptographic attestation, ensuring the hardware hasn’t been tampered with before use.
Support for Multiple Blockchains With Hardware‑Level Isolation
Ledger supports thousands of assets while keeping each blockchain app isolated from others, reducing cross‑app attack surfaces.
In the high-stakes world of cryptocurrency, where transactions are irreversible, security isn't just a feature – it's the bedrock of trust. Ledger empowers you to navigate this landscape with confidence, providing the most robust defense against evolving threats and granting you true ownership and control over your digital assets. Our security-first philosophy is the driving force behind every Ledger product. Ledger secures crypto using Secure Element hardware, offline key storage, a hardened OS, and physical transaction verification — all designed to keep private keys safe even if the connected computer is compromised.
