About Us

Metaflows, Inc. is a California corporation founded by Livio Ricciulli, with significant help from Phillip Porras and Matt Jonkman. Livio and Phil collaborated at the Computer Science Laboratory of SRI International where intrusion detection was first developed back in 1983. Following recent compelling research results and prior commercial success, the founders were commissioned by the National Science Foundation and The Army Research Office to commercialize recent, significant results in network security research through the founding of Metaflows. The resulting product (The Metaflows Security System or MSS) has been growing organically since then thanks to its strong technical differentiations. Most of the team members at Metaflows have an engineering background and are exclusively focused on product development and customer support.

Great system, easy to setup, great support

System Administrator

Metaflows does a great job in intrusion detection and prevention, and has stopped many new infections on our network from getting outside of the network. The interface itself could use some work, as far as ease of use, but once you can get around in the system it's not bad at all and full-featured. Their support is FANTASTIC, and they will quickly answer your call (I have never had a wait time) and immediately assist you in whatever you need. They are very, very knowledgeable about their product, and will help you tune your sensors to however you see fit.
