TLSense routers are intended for customers needing high VPN throughput or high IDS/IPS performance in addition to high routing performance and low latency. This model has roughly 4-5x better OpenVPN performance than APU.

Hardware supports pfSense®, OPNSense, OpenWRT as well as Windows, Linux, OpenBSD, and other operating systems.

This router has on-board 8GB storage intended for the operating system. If you would like to get more space, buy additional 128GB M.2 SSD.
