What is Data in transit?

Data in transit is digital information that moves between devices, systems, applications, or networks. Unlike data at rest, which remains stored on a device, or data in use, which an application actively processes, data in transit travels across communication channels such as the internet, private networks, or wireless connections.

Organizations continuously transmit data in transit when users browse websites, send emails, access cloud applications, make online payments, or synchronize files between devices. Because attackers may intercept this data while it travels across networks, organizations must protect it using secure communication protocols and encryption.

Protecting data in transit is a fundamental part of cybersecurity and helps organizations maintain the confidentiality and integrity of sensitive information.

Why it matters

Data often travels through multiple networks before reaching its destination. Without appropriate security controls, attackers may intercept, modify, or steal sensitive information during transmission.

Protecting data in transit helps organizations:

  • Prevent unauthorized interception of sensitive information.
  • Protect customer and business data.
  • Maintain data integrity during transmission.
  • Support compliance with privacy and industry regulations.
  • Reduce the risk of man-in-the-middle (MITM) attacks.
  • Build trust in digital services and online communications.

Securing data in transit helps ensure that only authorized parties can read and use transmitted information.

Common methods for protection

Organizations use multiple security technologies to protect data as it moves across networks.

Method Purpose
Transport Layer Security (TLS) Encrypts data transmitted between applications and servers
Virtual Private Networks (VPNs) Creates encrypted communication tunnels over public networks
Secure Shell (SSH) Secures remote administrative access and file transfers
HTTPS Protects web traffic using TLS encryption
Secure email protocols Encrypt emails during transmission between mail servers
Mutual authentication Verifies the identity of both communicating parties

Organizations often combine these technologies to strengthen communication security.

Data in transit vs data at rest vs data in use

Data exists in different states throughout its lifecycle.

Data state Description
Data in transit Information moving between devices, applications, or networks
Data at rest Information stored on a device, database, or storage system
Data in use Information actively processed by an application or user

Organizations should apply appropriate security controls to each data state because each presents different risks.

How Hexnode helps protect

Hexnode UEM helps organizations secure the endpoints that send and receive sensitive information. Administrators can enforce device security policies, configure encryption on supported platforms, deploy operating system updates, manage approved applications, apply device restrictions, and monitor device compliance from a centralized console.

Hexnode UEM also supports certificate management for supported platforms, helping administrators deploy digital certificates used for secure network authentication. Combined with device security controls, these capabilities help organizations strengthen the protection of data as managed devices communicate with enterprise resources.

FAQs

No. Data in transit is not automatically encrypted. Organizations should use secure protocols such as TLS, HTTPS, SSH, and VPNs to protect sensitive information while it travels across networks.

Examples include emails, online banking transactions, cloud file synchronisation, web browsing sessions, video conferencing traffic, API communications, and data exchanged between enterprise applications.
