The best part is its ability to sync with other cloud services such as Office 365 or Google Apps. It also offers some great features like multi-factor authentication (2FA) if you want that level of security in your organization. I wish there was an option to use 2FA without having to enroll users into this service. There are many options out there but we decided on titaniam protect since their pricing is more reasonable than others and they offer additional functionality not found elsewhere. We have seen a reduction in phishing attacks since moving to titaniamprotect.
