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. InstaSafe ZTAA relies on continuously assessing the trust and risk associated with every user, and the context of their access request, and simultaneously employs a system of comprehensive authentication before grnating least privilege access. By only making authorised applications accessible to the user, and not exposing the network to these users, ZTAA serves to negate the exploitable attacks surface

Remote workforce, BYOD assets, and third-party access have created a new security dilemma for organizations. Relying solely upon a VPN as security for remote workers and third-party access is insufficient to protect the network. While VPNs provide a degree of protection through encrypting inbound traffic, their security failure comes through providing full network access to users with no privileged access demarcation. RevBits ZTN encrypts, authenticates, and securely connects external users, over SSL/TSL, to internal network assets and applications to which they have specific access without granting full network access. Moving the network perimeter to the endpoint RevBits Zero Trust Network (ZTN) helps isolate and protect your internal assets. As the network perimeter moves to where the user is, RevBits Zero Trust Network (ZTN) helps isolate and protect internal network assets without the necessity of implementing complicated network segmentation.
