We had no other solutions on our shortlist. We had Correlix in place.

We evaluated the product against ExtraHop which you could argue was not the correct thing to do as the products are targeted for similar but different use cases. We, quite late in the day shifted the PoC towards comparing Corvil with Velocimetrics but as we were running out of time and already liked what we saw with Corvil, we decided to proceed with them.

The company also evaluated Ixia and cPacket.

I am familiar with Ixia TradeVision, but I don't think it is up to par. They just entered this realm.
