The trial period was great; we were able to leverage the virtual edition to fully test features before bringing the actual hardware onsite for a POC. The solution has worked well and has outclassed our previous setup in both ease of use as well as efficiency and speed. *UPDATE* In this update I would like to share my experience with hardware support from Cohesity, as our units have now been in service for over 5 years. I received a notification from the system that the expected lifespan of one of the solid state drives was now down to 20%. Cohesity proactively replaced every one of our nodes, one at a time, so there was zero downtime to our backup cluster. This was unexpected and very welcome. They do stand behind their hardware as well as their software. I'm updating my rating of service and support to 5 stars because of this. *UPDATE 2* As a further update we have now retired our original cluster and installed a new cluster. The new cluster increased network speed, node count, and capacity. I think this is the highest compliment a review can give - we liked the solution enough to vote with our wallet a second time. *UPDATE 3* We continue to have great success with our cluster. Support has been helpful when we need them. I'm looking forward to future enhancements concerning additional hypervisors.

As part of a Network team, I saw such a product coming to me without a valid RFP. Unfortunately, we do have a highly regulated infrastructure and Cohesity is struggling to follow our standards. It might be a nice tool, but from a security perspective the product is incredibly naive. Segmentation of activities (backup/ admin) is complicated as the system is missing a real out of band solution.
