The way we work has changed. People can now work anywhere and not only from their office. Applications are now hosted in the cloud and not on-premise. The company network perimeter is now distributed across the internet. Traditional, network-centric VPNs for remote access are not only difficult to maintain and outdated, but also expose businesses to security risks. It is expensive and time-consuming to purchase, deploy, and maintain VPN infrastructure. Hackers can expose entire networks if they are unable to secure access at the application level. Twingate allows organizations to quickly implement a zero trust network that is more secure than VPNs. Twingate is a cloud-based service that allows IT teams to quickly set up a software-defined perimeter without having to change infrastructure. It also centrally manages user access to internal apps, no matter if they are in the cloud or on-prem.
