NSS Labs just released the first 10Gbps IPS certification as part of our 10Gbps IPS group test. A number of vendors are offering 10Gbps appliances: Juniper, McAfee, Enterasys, Force10, Sourcefire. McAfee's M-8000 was the first to pass our extensive testing and receive certification. In addition to meeting the rigorous performance requirements, the product scored exceptionally well on the security effectiveness testing. Read the full report here.
Still other vendors are taking the solution approach by including a load balancer and multiple IPS devices. It should be noted, these could use any reasonable switching approach to stack/VLAN multiple physical IPS devices into one logical unit. Think of products from the likes of: IBM, Cisco, Crossbeam (Chassis/Blade), Sourcefire, TippingPoint, TopLayer, etc. Depending on what a company already has installed, and what their growth/infrstructure plans look like, this model could also work well. It will come down to a TCO and effectiveness decision.
It should be noted that this was an award that was a long time in the making since we announced the testing in the summer of 2008; and many vendors had announced products well before that. Indeed there are many reasons why it takes so long. #1 - It's hard to get right. It is not necessarily easy for a vendor that has a 'successful' 1Gbps IPS to deliver the same quality product that truly meets 10Gbps requirements. We just held a technical webinar on the topic of 10Gbps IPS. We covered the challenges that vendors face when making a 10 Gbps IPS, as well as those faced by buyers who are evaluating these products. The webinar is recorded and available here. I was pleasantly surprised to receive several comments that this was the "best webinar ever," and very informative. If you don't have time to listen to the webinar, you can probably at least peruse the slides.
As we've seen in our testing, there are plenty of gotchas to look out for. And for this large and complex of a purchase, most of the potential buyers do NOT have the capabilities to adequately evaluate and test such a product. In such cases it should really behoove the vendors who have done a good job to have their products validated by a competent 3rd party. So be sure to ask your vendor what kind of testing and certification the product has gone through. (OK, somewhat of a trick question: I must confess I don't know of any other lab capable of doing the level of testing that we do, either in terms of throughput or security ;-)
