VPN Consortium Interoperability

The VPN Consortium’s (VPNC) testing program is an important source for certification of conformance to IPSec standards. With rigorous interoperability testing, the VPNC logo program provides IPSec users even more assurance that the XSR will interoperate in typical business environments. VPNC is the only major IPSec testing organization that shows both proof of interoperability as well as the steps taken so that you can reproduce the tests.
