The customer support team, which are all extremely helpful! They have been able to solve any issues that I've had with their product throughout our partnership in such an efficient manner (usually within 24 hours). It's not perfect but it has helped my organization be more secure for sure!! There isn't much dislike about this program as of yet other than being somewhat expensive compared at some competitor products out there - however if budget allows then definitely look into using them- saves money while helping improve overall IT department efficiency/security standards.-.
