I use this to protect my primary and shared email boxes for my small business. I only have a few email addresses so getting enterprise-grade protection for a smaller account is normally difficult.
I utilize every feature ranging from Spam Filtering & ATP to the automated encryption and archiving feature.
The best part is, I rarely have to access the portal as everything is set up and tweaked the way I wanted it. But the feature set is incredibly granular and allows for deep levels of customization.
I don't have to worry about malicious attacks. My emails are automatically encrypted and automatically archived. This allows me to save time & money. I do not have to fuss with each and every suspicious email that comes in and I have it set to give me a report every 4 hours. So I never miss an email and give myself the opportunity to make sure that everything bad is caught and everything good can be allowed through. This service has allowed me to focus on my core environment and ensure the safety of my customer's data.
