Their customer service team was very helpful and knowledgeable. I had some questions about their products and they were able to help me out immediately. They are also very transparent and open to feedback. Nothing really. I think it's a great product that helps keep your data secure. It helped us get rid of our old VPN service and we haven't looked back since. We have been using it for over 2 years now and never had any issues or complaints. It has made our life easier when it comes to keeping our sensitive information safe.
