How To Select The Right Encryption For Your Organization?

For every organization protecting their data is the first thing that comes into their mind. But now the question is how to select the proper encryption for your organization?

How To Select The Right Encryption For Your Organization?

Data encryption may be perceived as binary in the boardroom: if it is used, the company’s assets are safe; if it is not used, its data assets are not secure, and it is time to panic. ( Right Encryption For Your Organization )

The reality, however, is rarely that straightforward for security professionals tasked with safeguarding sensitive data. At a high level, data encryption types may be divided into the four tiers of the technological stack where data encryption is often used:

1. Media or full-disk

2. The file system

3. The database

4. Implementation

The lower the stack encryption is used, the easier and less invasive the implementation. However, the number and kinds of threats that these data encryption methods can address are limited. Organizations may often achieve greater levels of security and neutralize more dangers by implementing encryption higher in the stack.

Right Encryption For Your Organization – Disk Encryption

Full-disk encryption (FDE) and self-encrypting drives (SED) encrypt and decrypt data written to and read from the disk.

Advantages of FDE/SED:

  • The most straightforward technique of introducing encryption Transparent to apps, databases, and users
  • High-performance, hardware-based encryption

FDE/SED Limitations: 

  • Addresses just a subset of threats—protects against physical loss of storage medium.
  • There are no measures to protect against advanced persistent threats (APTs), malevolent insiders, or external attackers.
  • Meets the most basic compliance criteria
  • It does not provide granular access to audit records.

Important takeaways:

  • The functional counterpart of FDE is available from mainstream cloud providers, with the constraints noted above.
  • FDE is appropriate for laptops, which are vulnerable to lose or theft. However, FDE is unsuitable for the most prevalent hazards encountered in data centers and cloud systems.

File Encryption

Encrypting data at the file or volume level (usually used for databases) provides security controls via software agents installed in the operating system. ( Right Encryption For Your Organization )

Agents intercept disk reads and write and use rules to decide whether the data should be encrypted or decrypted. Mature file-system encryption technologies provide robust policy-based access restrictions, including those for privileged users and processes, as well as granular logging.

Benefits of File-Level Encryption:

• Transparent to users and apps, removing the need for enterprises to alter applications or change related business processes.

• Allows for the storage of both organized and unstructured data.

• Implements tight controls to prevent privileged users’ exploitation and fulfill standard compliance requirements.

• Provides detailed file access records and accelerates threat detection via SIEM systems, which may be utilized for security intelligence and compliance reporting.

Limitations of File-Level Encryption:

• Because encryption agents are operating system-specific, it is critical to ensure that the solution chosen supports a wide range of Windows, Linux, and Unix platforms.

Important takeaways:

• For many companies and purposes, file encryption is the best option. Its extensive safeguards cover most use cases, and it is simple to build and maintain.

Right Encryption For Your Organization – Database Encryption

This method allows security teams to encrypt some data inside a database or the entire database file. This category comprises various database manufacturers’ transparent data encryption (TDE) solutions. ( Right Encryption For Your Organization )

Column level encryption is also included in this category. This database encryption mechanism enables users to encrypt selected information or properties rather than the whole database file.


  • Data in databases, which are crucial repositories, are protected.
  • Establishes robust defenses against various risks, including dangerous insiders—even a rogue database administrator in certain situations.
  • On a per-column basis, it provides transparent encryption of sensitive database material.


  • Offerings from one database vendor cannot be applied to databases from other vendors when using TDE.
  • TDE does not provide centralized management of various vendor databases or other environment sections.
  • Only encrypts database columns or tables, leaving configuration files, system logs, and reports unprotected.

The bottom line:

While TDE systems might solve particular tactical needs, they do not allow enterprises to handle security across diverse settings. As a consequence, they may create serious security holes in businesses.
