As business environments become increasingly digital, the way companies store and share documents has a huge impact on both productivity and security.
While many companies still rely on NAS (Network Attached Storage), more organizations are now switching to document centralization solution.

Both approaches share a common goal — storing and managing documents in a central location — but they differ significantly in terms of protection, manageability, and efficiency.
Let’s take a closer look at the differences between the two systems.

 

 

 

 

What Are NAS and Document Centralization?

 

🔹 NAS (Network Attached Storage)
NAS is a network-connected storage device that allows multiple users to save and share files through a file server.
Its relatively low initial cost makes it a popular choice, especially among small and medium-sized businesses.

 

🔹 Document Centralization Solution
A document centralization solution manages all documents in a single central server.
Instead of saving files on local PCs, users create, store, and share documents directly in the centralized environment.
Beyond simple storage, this approach consolidates dispersed content and establishes an efficient, secure collaboration system.

 

 

 

 

Common Ground Between NAS and Document Centralization Solution

 

Both systems allow teams to store and manage documents in one place, enabling sharing and collaboration.
They also support permission-based access control, providing a basic level of document protection.

 

 

 

 

NAS Limitations — Why Companies Are Concerned

 

While NAS offers an easy initial setup, its limitations become clear as the organization grows — especially in terms of protection and efficiency.

 

1. Limited Protection and Management

- Files are stored without separate encryption, creating a risk of data exposure.

- It’s difficult to precisely control user actions such as copying to USB/external drives, printing, downloading, or screen capturing.

- Since users must manually upload files to NAS, issues like missing files and overwriting errors frequently occur.
 

2. Inefficient Collaboration

-  NAS systems offer limited version control and audit history, making it difficult to track changes.

-  Due to file name–based search, it is difficult to search documents by content or metadata, and document utilization is limited.

-  Since NAS operates as a network drive, performance degradation may occur depending on network traffic.

 

 

Why Companies Choose Cyberdigm’s Document Centralization Solution

 

Document centralization solution overcome NAS limitations by integrating secure management with efficient utilization.

 

1. Strong Protection and Systematic Management

✅ Centralized storage: All documents are safely stored on a central server, protected even if a user’s PC is formatted, lost, or damaged.

✅ Content security policy: Fine-grained control over external storage devices (USB, external drives), printing, screen capture, clipboard copy, and more.

✅External sharing approval: Important files require internal approval before being sent outside the organization, preventing unauthorized leaks.

 

2. Efficient Work and Collaboration Environment

✅ Document property search: Quickly and accurately find documents by name, content, author, or file type.

✅ URL-based sharing: Collaborate instantly without sending the original file — access via unique document URLs eliminates version conflicts.

✅ Virtual disk–based: Documents are executed within a sandbox* area of the local disk, eliminating performance degradation caused by network traffic.

*Sandbox: An encrypted virtual disk drive that runs externally sourced files in an isolated environment, preventing untrusted external files from affecting the main system.

 

 

Beyond Storage — Toward Intelligent Management and Utilization

 

NAS is a storage method that carries inherent limitations in security and collaboration efficiency.

It is not sufficient to ensure the safe protection of an organization’s critical documents.

Cyberdigm’s Document Centralization Solution enables centralized management of all documents, delivering both robust protection and efficient utilization.

For sustainable growth and a secure digital transformation, it is time to move toward document centralization solution.
