What is the primary function of BitLocker in Windows?

The primary function of BitLocker in Windows is to encrypt hard drives. BitLocker provides full disk encryption, which helps protect the data on the hard drive from unauthorized access. This is especially important for laptops and portable devices, where the risk of theft or loss is higher. By encrypting the entire drive, even if the device falls into the wrong hands, the data remains secure and cannot be easily accessed without the proper credentials or recovery key.

This encryption process ensures that sensitive information and files are not exposed in the event of physical theft, creating an additional layer of security for users. BitLocker uses strong encryption algorithms, making it a robust solution for safeguarding data against potential breaches. The focus on encryption directly addresses security needs and compliance with various regulations that require the protection of sensitive information.
