The landscape of work has undergone a significant transformation, enabling individuals to operate from virtually anywhere rather than being confined to their offices. Cloud-based applications have replaced on-premise solutions, leading to a distributed company network perimeter that spans the internet. Traditional VPNs, which focus on network-centric remote access, have become not only cumbersome and outdated but also pose considerable security vulnerabilities for businesses. The costs and resources associated with acquiring, deploying, and maintaining VPN infrastructure can be staggering. When access isn't secured at the application level, hackers may be able to compromise entire networks. Twingate offers a solution for organizations by facilitating the swift implementation of a zero trust network that outperforms VPNs in security. As a cloud-based service, Twingate enables IT teams to establish a software-defined perimeter rapidly without necessitating any changes to existing infrastructure. Moreover, it provides centralized management of user access to internal applications, regardless of whether these applications are hosted in the cloud or on-premise. This modern approach not only enhances security but also simplifies access management across diverse environments.
