Transparent Data Encryption (TDE) is a technology used to encrypt data at rest, which means that it is encrypted while stored on disk or other storage media. The purpose of TDE is to eliminate the negative effects of data theft or accidental sharing of sensitive data by making it unreadable to unauthorized users. By encrypting data at rest, TDE provides a high level of security for sensitive data, which is suitable for organizations that handle large amounts of confidential information.

Benefits:

1. Protection of sensitive data at rest: TDE provides an additional layer of security for sensitive data, ensuring that it cannot be accessed or read by unauthorized users if the storage media is lost or stolen.
2. Transparent operation: TDE operates transparently to applications and users, which means that it does not require any changes to the application or user interface. This makes it easy to implement and manage, as it does not require any additional user training or application modifications.

Limitations:

1. High performance hit: TDE can have a high performance hit, as files need to be encrypted and decrypted whenever they are operated on. This can impact system performance and slow down file access times.
2. Lack of flexibility: When a specific file type is protected, all files of that type are encrypted. This can limit the flexibility of the solution and make it difficult to apply different levels of protection to specific file
3. Integration challenges: TDE can be challenging to integrate with other systems, as the files are encrypted. This can complicate data sharing and collaboration, especially with external partners or vendors.
4. Limited protection: TDE is primarily focused on protecting data in transit and in storage, but it may not protect data in use. This can create security gaps that could be exploited by malicious actors.
5. Difficulty exiting the solution: TDE can be challenging to exit if a business decides to change their data protection approach. This is because IT will need to decrypt all the protected files, which can be time-consuming and resource-intensive.
6. Higher risk of data loss: Repetitive encryption and decryption can increase the risk of data loss due to file corruption. It might shorten the hard drive’s lifespan with the extra I/O, especially for nowadays’ more common SSD drive.
