Their support is second to none. I wish other SaaS companies are as responsive and helpful as they are. When you have an issue with IT infrastructure, you don't want to wait around while your employees lose productivity. We've had their CEO reach out to us directly when there were issues. Also they have great documentation that explains how to integrate Foxpass into your infrastructure which helps a ton.
Also, you can't beat the value for what Foxpass offers. Their competitor, JumpCloud, is already 2x more expensive per seat. If you want to run your own servers, be prepared to spend a considerable amount of your personnel's time making sure everything is running smoothly, up-to-date, and secure. As a startup, we can basically get enterprise level IT infrastructure for fraction of the cost.
