I haven't encountered any issues with Reve over 9 years we used it at our previous employer so there are no current downsides other than they've been acquired by Kaspersky which is not exactly my favorite security vendor anymore (they're more in-your face about spying).
We previously had an antiviral software from Symantec but one day their website was hacked - and someone took ownership of all customer accounts' data! No way would anyone want them back after this incident. I like how easy it is with this program because you can do so many things in one place! It's very helpful if your organization uses multiple computers at once (such office computer labs). The only thing i dislike about Reve endpoint security was having issues accessing some websites when working remotely from home without my VPN connection active but other than that everything else has been great!! Nothing really bad comes out after purchasing our product which makes me happy :).
