InstaSafe is redefining the challenge of secure access to modern networks by leveraging Zero Trust principles with its security solutions, that ensure seamless access to cloud applications, SAP applications, on-premise data, IoT devices, and multiple other neoteric use cases. InstaSafe discards traditional VPN based conceptions of a network perimeter, instead moving the perimeter to the individual users and the devices they access. The Zero Trust approach followed by InstaSafe mandates a “never trust, always verify' approach to privileged access, without focusing on network locality.

Big Network connects networks and services securely and easily between people, places and clouds from anywhere. We combine simplicity with mesh-vpn, cloud services and sdwan with one button. Big Network also offers broadband services, a cloud marketplace, and a partner network. Accenture estimates that 83% of businesses will continue to operate with hybrid workforces. Big Network allows users to securely and easily connect networks and services between their offices, homes, workplaces, clouds, and other devices. Private networking can be expensive, complicated, and difficult. There are many legacy technologies available, each driven by a different ecosystem of software and hardware vendors.

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 Traditional, network-centric VPNs for remote access are not only difficult to maintain and outdated, but also expose businesses to security risks.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.

Trustgrid is the SD-WAN for software providers. The Trustgrid platform uniquely addresses the needs of SaaS application providers who rely on customer or partner-controlled environments. By combining an SD-WAN 2.0, edge computing, and zero trust remote access into a single platform we allow software providers to manage and support distributed application environments from the cloud to the edge. Simplify connectivity, enhance security, and guarantee network availability with Trustgrid.
