Ledger devices offer the same industry-standard security. For starters, the company uses certified Secure Element (SE) chips which are tamper-resistant and often referred to as hardened microcontrollers. Similar to air-gapped cold storage, the device stores private keys on the secure chip, so they’re never exposed. The chips are certified using the Common Criteria (CC) EAL5+ process. Moreover, the French National Agency for the Security of Information Systems (ANSSI) independently audited and verified the Nano S and X security. 
Unlike other hardware wallets, Ledger devices use a proprietary operating system (OS) called the Blockchain Open Ledger Operating System (BOLOS). According to Ledger, “Ledger hardware wallets are the only devices in the market that uses a Secure Element in combination with a custom Operating System.” Additionally, the framework isolates crypto apps reducing cyber risks. 
Personal security measures include:

A minimum of four digits for the pin code

Users must push both physical device buttons at once to purchase altcoin

A 24-word recovery phrase that only shows up on your device, not the apps
