If you are already an Office 365 Mail user, you will already be aware that your office 365 mail service comes with a bundled Anti-Spam, Malware, Virus & Phishing agent.  However if for any reason you are not satisfied with the levels of protection and functionality Microsoft offers an add-on service call Advanced Threat Protection (ATP).

Advanced Threat Protection for Office 365 Mail is available per user per month, contact VBT for more details.
