  BitLocker uses Advanced Encryption Standard (AES) with either 128-bit or 256-bit keys, providing robust protection for data.
• Seamless Integration
  BitLocker is integrated with Windows OS, making it easy to deploy and manage within the Microsoft ecosystem.
• TPM Integration
  BitLocker can use the Trusted Platform Module (TPM) chip to secure encryption keys, enhancing security through hardware.
• Group Policy Management
  Administrators can manage BitLocker settings and deployment through Active Directory and group policies, making it suitable for enterprise environments.
• Recovery Options
  BitLocker provides multiple recovery methods, including a recovery key, recovery password, or integration with Active Directory, ensuring data access in case of issues.

Possible disadvantages of Windows BitLocker

• Performance Overhead
  Encryption and decryption processes can introduce performance overhead, which may affect system performance, especially on older hardware.
• Compatibility Issues
  BitLocker requires specific hardware features like TPM 1.2 or 2.0, and its usage may be limited or unsupported on some older devices or non-Windows systems.
• Complex Recovery
  While recovery options are available, they can be complicated to manage, especially for less experienced users or in environments without proper configuration.
• Limited Non-Windows Support
  BitLocker is designed for Windows OS, making cross-platform accessibility and management challenging, particularly for organizations using multiple operating systems.
• Potential Data Loss Risk
  Improper management of encryption keys or accidental disk damage can lead to data loss, emphasizing the need for careful setup and key management.
