Network Security and SD-WAN

Software-defined WAN and Zero Trust
IDC estimates that the number of installed software-defined wide area networks (SD-WAN) will grow in the coming years. Total global revenue from their operation will exceed $6 billion in 2020, with a compound annual growth rate of over 90% over the next five years.


SD-WANs can significantly increase the level of network security albania whatsapp data to traditional territorial networks. First of all, this is due to the improvement of the mechanism for selecting access policies in SD-WAN. Now companies can better control access rights to the network and applications, and more efficiently track the operations performed by connected clients.

Implementation of SD-WAN simplifies the connection of branches - this also contributes to the growth of overall network security. It becomes possible to implement end-to-end encryption in any network areas, both within segments in the local part of the network and when interacting with clouds. The use of the IPSec protocol (256-bit) also helps reduce threats.

The implementation of SD-WAN enables the deployment of software-defined firewalls on endpoints. They can be used to perform stateful packet inspection (stateful firewalls), thereby building additional protection against intrusion and checking traffic for correctness.

The ability to reduce service costs is important. By securely routing traffic over the public Internet, SD-WANs eliminate the need for expensive private multi-protocol switching (MPLS) networks.
