QuickSec™ Toolkit, complete client/server IPsec software

Carrier-grade IPsec SDK for Networking OEMs and Cloud deployments

QuickSec® Toolkit is a complete software stack to build robust IPsec VPN gateway or IPsec Client. QuickSec® Toolkit is a IPsec SDK written in highly portable C source code and free of GPL constraints. It enables robust and standards compliant authentication, confidentiality and data integrity. It is widely used in products such as enterprise security gateways, high security government appliances, high capacity carriers’ gateways, eNodeB, mobile devices and printers. It is deployed on platforms including Linux, Windows and NetBSD as well as in Cloud (SDN/NFV) environment. It is available as a client toolkit, a server toolkit or a bundle solution.


Accelerate time-to-market and reduce R&D costs

IPsec is a complex protocol with many options and features. The QuickSec team has a long experience in delivering IPsec technology to leading gateway vendors and supporting IPsec integration in a wide variety of platforms. By using QuickSec® IPsec Toolkit, you benefit from a proven, tested product that is updated and maintained regularly by our security experts. You also benefit from a support organization manned by experienced engineers that can guide you throughout the life time of your product. 



As our customers develop products that must work seamlessly with various IPsec implementations, QuickSec® Toolkit supports the 90+ standard specifications required to work with the various flavors of IPsec. The QuickSec team has worked on IPsec technology for 20 years, and INSIDE Secure co-authored the latest IKEv2 specification (RFC 7296). Interoperability is verified as part of the QA process in INSIDE Secure’s own laboratory.


High scalability

QuickSec® Server Toolkit is designed for high scalability and has been deployed with over 1 million IPsec tunnels. Large deployments have specific needs such as:

  • High session set-up rate: QuickSec is able to reach 2000 IPsec tunnel establishment per second with only 2 CPU cores. It also scales well on multicore architecture and performances are stable with high number of sessions. It can leverage any cryptographic hardware acceleration present on the platform.
  • High Availability (HA): The server toolkit includes high availability APIs for import and export of IKE and IPsec SAs (Security Association) for device redundancy and failover.
  • Gradual restart: When a gateway with a large number of IPsec connections restarts, re-establishing all connections may be time consuming. Instead it is possible to only restart the IPsec connections when needed by triggering the IKE session establishment only when packets are received.
  • Easy debugging: To resolve problems in large deployments without impacting performance, it allows to request detailed logs only for specific tunnels. 


To allow a Cloud network to provide multiple networks or an eNodeB to support multiple operators, QuickSec Toolkit supports multiple VRF (Virtual Routing and Forwarding) instances.


Designed to integrate with any dataplane

Most platform vendors provide an IPsec dataplane optimized for their platform. It is therefore essential that QuickSec Toolkit integrates seamlessly with any IPsec dataplane.
It is pre-integrated with Netlink API. It seamlessly integrates with Linux kernel IPsec dataplane for embedded integration, or with 6WINDGate's IPsec dataplane for Cloud’s integration (over DPDK). It is also designed to integrate with any IPsec dataplane through its Common Dataplane API.
