Hardware wallets are probably the most robust form of security you can have for your Bitcoins or any other cryptocurrency. They allow you to send and receive Bitcoins on any computer, even one that is compromised with malware, with the knowledge that your transaction will still go through as intended.
The way the hardware wallets achieve maximum security is by storing your private key and signing your Bitcoin transactions offline so someone trying to hack your wallet remotely won’t be able to do so. Most hardware wallets also use a second screen/device to verify actions on your wallet such as signing transaction. This way, if a hacker gains control over your computer, he still can’t do any harm since he requires access to the physical device connected to your computer as well.
