The customer service is great! They are always quick to respond and help me solve my issues. I recently had an issue with my password expiring. A few days later they emailed me asking if I was having any problems again and offered to help me solve it. Great team! I've been a regular user of CISS for years now. There's nothing that I dislike about this product. It's very easy to use, has all of the features you need, and is extremely reliable. We do not have any security concerns at our office. My IT department can't be bothered to set up their own security so we rely on CISS to protect us.
