Cloud VPN Gateway

Increasing global footprint of enterprises and mobility of workforces has increased the demand for traditional VPN services in terms of security and performance. Various devices other than computers connect to remote office locations through public networks. Securing the data transmitted between these devices and offices spread across geographical locations has become mission critical in a world with new security threats coming from all directions.

A Cloud VPN Gateway solution can be used to provide VPN connectivity to Wi-Fi users or wired residential/enterprise broadband subscribers. It forms an integral part of a Virtual CPE solution with the addition of Firewall, IDS/IPS and other services along with the IPsec VPN Gateway.

Cloud VPN Gateway Framework

ALTEN Calsoft Labs has developed a Cloud VPN Gateway framework to address network service providers need, to deploy a future proof, scalable, carrier-grade IPsec VPN Gateway infrastructure that delivers breakthrough performance on industry standard X86 hardware.

ALTEN Calsoft Labs Cloud VPN Gateway is targeted at broadband service providers. The highly scalable carrier grade framework is carefully designed to provide standards-based IPsec VPN services and management functionality, with significantly higher performance compared to traditional VPN Gateway appliances.

The framework has been architected to leverage Intel DPDK to deliver up to 25x performance gain in packet processing on IA, and extensively tested on commonly available servers with Intel Xeon processors.
