This service acts as a filter and helps hinders the process of reading data on one side and can only decode data on the other side. Even if your internet connection is compromised, this procedure can prevent illegal data theft.

Business VPN network
Site-to-Site-VPN
Site-to-site VPN is chosen by many companies with many geographically distant offices. This is considered an internal private network, which allows authorized personnel to remotely access internal network resources such as files, applications and servers.
AWS Site-to-Site VPN is a fully managed service created by a VPN Close connection between office network and AWS resources from the IP security tunnel (IPSec). Especially for globally distributed applications, this is an option that delivers excellent performance.
This service allows users to upgrade to forwarding VPN traffic to the nearest AWS network endpoint. Additionally, the cloud gives them the ability to connect to corporate data centers and branch offices with applications and services while optimizing security.
Site-to-site VPN is suitable for companies with many branches to choose from
Client VPN with Open VPN
The network administrator is responsible for Client VPN Setup and configuration for VPN service. Therefore, users simply need to be granted access to connect. This means employees can establish VPN connections from their local computers or devices to the corporate network.
AWS Client VPN là VPN managed remote access. This solution helps users securely access resources, even across WS and local corporate networks. They offer flexibility and can easily be scaled up or down depending on customer needs.
Client VPN is suitable for on-premise business models
SSL-VPN
SSL VPN (also known as Secure Socket Layer Virtual Private Network) allows users Secure remote accessThe connection between private devices and the office network takes place via a web portal and an SSL-protected tunnel.
In this case, the company allows employees to work remotely on a large scale and provides support Laptop separately for each member is very expensive. Therefore, SSL VPN is a solution that is becoming increasingly popular.
