John Pescatore and I published today “Defining The Next Generation Firewall” (NGFW). The note ‘liner notes’ may help provide some context. Gartner has been talking about Next Generation Firewalls (NGFW) for a while – in 2004 we had a note titled “Next generation Firewalls Include Intrusion Prevention”.
We have been increasing the weighting for NGFW capabilities in each successive Enterprise Network Firewall Magic Quadrant (MQ), so there will not be a separate MQ for NGFW: this next generation is not a new product or an artificial label, but a progression of firewall and IPS technology.
The note was published now because the market is starting to see early versions of these enterprise class products: some firewall vendors waking up to a big IPS market, changes in network traffic to being squeezed through fewer ports and protocols, an emerging firewall policy management market, and the signaling between other network security products. In the note we also specify what a NGFW is not, in response to inquiries from Gartner clients and as a further guide to where this market is heading.
