Enterprise message buffering & routing
ioBufferPro is an enterprise-grade message buffering and routing application designed for environments where reliable, persistent message delivery is critical. It provides a secure alternative to using a VPN — purpose-built for IT managers, system integrators, operations managers and network administrators who need data to keep flowing between critical systems, even when networks don't cooperate.
