Key learnings from peers

Valuable Features

  • "The most valuable features are its ease of use and deployment, and being able to collapse several solutions into a single solution, all contained within a single bit of hardware and software."
  • "It is very easy to use. Both the GUI and CLI interface are consistent, which makes the ease of access throughout various constituencies possible. It's also well-documented and logical."
  • "It has freed up a lot of our IP space and has been extremely reliable. We have set it up in a high availability scenario, testing it many times. It has been absolutely perfect in terms of failover."

Room for Improvement

  • "There are a couple of features that they could look to implement, versus the workarounds that they have in place. Regarding IPv4 and IPv6, there are a couple of opportunities in there that they are working on, as well."
  • "They don't track concurrent port usage. We have to do that in another way and it's not a very clean way. That is something that I know they could do, but they don't."

Pricing

  • "The FlexPool consumption-based licensing model has the ability to spin up VMs as needed for NAT, as well as their ADC, which is their load balancing stuff. We are considering that, as that is a pretty attractive feature."
  • "The cost to buy it initially was a single purchase price. This was a cost for the hardware and software, but we got a year of service with it. Annually, we pay them a service fee, but it's not much money."
These insights are based on the in-depth reviews provided by peers to help you make a better buying decision.
