Twingate
Twingate
The way we work has changed. People now work from anywhere, not just from an office. Applications are based in the cloud, not just on-premise. And the company network perimeter is now spread across the internet. Using a traditional, network-centric VPN for remote access is not only outdated and difficult to maintain, but exposes businesses to security breaches. VPN infrastructure is costly and time-consuming to procure, deploy, and maintain. Inability to secure access at the app level means hacks can expose whole networks. Twingate enables organizations to rapidly implement a modern Zero Trust network that is more secure and maintainable than VPNs. Delivered as a cloud-based service, Twingate empowers IT teams to easily configure a software-defined perimeter without changing infrastructure, and centrally manage user access to internal apps, whether they are on-prem or in the cloud.Starting Price: $10 per user per month -
