I have been working with DTS since they came into our market about 3 years ago! They are one of very few companies we can count as having 'proven' success in this space (security).
The support staff is amazing - from their technical experts who understand what you need right down through customer service personnel at all levels, there's nothing but positivity here every day!! Nothing specific; however my team has not found anything negative yet so far either. This IS important because it gives us peace-of mind knowing your business will be well taken care off by those skilled professionals when needed or wanted. We're solving security problems and helping customers stay secure using an array solution which includes physical devices/hardware AND also services like vulnerability scanning etc along side them.
