Application client

(also stand-alone application)

Application client definition

An application client is a software component. It runs on a client machine and utilizes a client-server architecture to communicate with a server-side application. It provides a user interface and communicates with the server-side application using a network protocol like HTTP, TCP/IP, or Remote Procedure Call (RPC). Application clients benefit enterprise applications, such as CRM, financial, and supply chain management systems. They also provide an interactive and responsive user interface in web apps and can enhance security and protect against cyber threats.

Application client examples

  • Two-factor authentication. It requires users to provide two forms of authentication to access an application or network, such as a password, and a second factor, such as a fingerprint, to increase security.
  • Secure communication. An application client helps users implement secure communication protocols, such as TLS or SSL, to protect against eavesdropping, data interception, and man-in-the-middle attacks.
  • Intrusion detection and prevention. Users can implement intrusion detection and prevention mechanisms to detect and prevent cyber attacks, such as SQL injection or cross-site scripting (XSS) attacks.
  • Vulnerability scanning. An application client can perform vulnerability scans of apps and networks to identify security weaknesses and potential attack vectors.
  • Access controls. Organizations can implement access controls to prevent unauthorized access to their applications or networks. Examples include password policies, user roles, and permission levels.

Application client advantages

  • Improves the user experience compared to a web browser.
  • Provides enhanced security features to protect against cyber threats.
  • Enables users to access data and application logic offline.
  • Can be optimized for your specific device or OS.
  • Provides a customizable and efficient user experience.

Application client disadvantages

  • Requires installation and maintenance, which can be time-consuming and complex.
  • Might not be compatible with all devices and operating systems.
  • Development and deployment can be expensive.
  • Can introduce security vulnerabilities.
  • May be less flexible than accessing an application through a web browser.
