The ease of use is great! It's not very difficult at all for our IT department or end users when it comes time implementing this product into an environment that already has other products installed (like Cisco).
I would say there are no downsides as far as being able to see how well implemented things were with regards to network monitoring/security alerts from multiple vendors such as Palo Alto Networks etc.. We have been using several different Network Monitoring tools over the years but we haven't found one yet which works like Cores does so easily across many platforms including Windows & Mac OS X environments without any issues - they do work flawlessly regardless if you're running them locally within your own computer system(server) OR remotely via VPN connections through remote desktop software packages available online free / cheap services out ther easwell too!!
