Network sandboxing

(also network traffic sandboxing or network security sandboxing)

Network sandboxing definition

Network sandboxing, sometimes called network security sandboxing or network traffic sandboxing, is a safeguarding method that segregates potentially dangerous network traffic within a virtual space, inhibiting it from making contact with the primary network. This strategy enables IT professionals to examine questionable network activity while ensuring the safety of their systems from potential threats.

Network sandboxing examples

  • Threat detection: Network sandboxing is used to detect zero-day threats and advanced persistent threats by evaluating their behaviors in an isolated environment.
  • Incident response: In the case of security incidents, network sandboxing helps in understanding the threat better and forming appropriate response strategies.

Advantages and disadvantages of network sandboxing


  • Security: Network sandboxing enhances network security by allowing potentially harmful traffic to be analyzed in a controlled environment.
  • In-depth threat analysis: It provides detailed visibility into network threats and their behavior, aiding in the development of more effective countermeasures.


  • Resource intensive: Network sandboxing can be resource intensive, demanding a significant amount of computational power and network bandwidth.
  • Evasive malware: Some sophisticated malware can recognize sandbox environments and evade detection by altering their behavior.

Using network sandboxing

  • Pair network sandboxing with other security measures, such as firewalls and intrusion detection systems, for a robust security posture.
  • Bear in mind that while network sandboxing is effective, it cannot guarantee full protection against all threats and should be part of a layered security approach.
