Cisco Secure Email Security Level With Office 365

Do you use Office 365 in your organization? If yes, what is your impression of the level of security for your environment provided by the combination of Cisco Email Security and Office 365?

At my previous organization, we were using the standard Office 365 controls and Email Gateway before we put in Cisco Secure Email Cloud Gateway. The amount of email and spam that we got, even malicious emails, through Microsoft was horrendous. We ended up having four different massive outages because of getting some viruses in the organization and some of our file servers along with encrypted user hard drives. We had four instances of major outages where we were down for probably 24 hours each time, and that was only because we had the backups. We also had some other measures where as soon as we saw any change in the root directory (as that data encrypts our file shares), we'd automatically shut the services down. However, this was an inconvenience for the users. You would end up getting the initial malware, then also having to do remediation to get it back to normal. When you have potentially hundreds of staff who are offline for 24 hours, it's a very big cost to the organization when you don't have your systems up and running. Once we put in Cisco Secure Email Cloud Gateway, these issues disappeared altogether, and we were thankful that the volume of spam emails decreased considerably. Office 365 is a good second check to Cisco Secure Email Cloud Gateway, but there's nothing that I've ever seen which has gotten through Cisco Secure Email Cloud Gateway that Office 365 has picked up.
