Advanced Threat Protection in Office 365

Office 365’s Advanced Threat Protection (ATP) delivers virtually unparalleled email security without impacting your productivity. Continuously evolving threats are a risk to businesses, but ATP has your company covered. It has numerous safeguards in place to protect you from new, sophisticated threats in real time, keeping your email secure.

URL Detonation

This feature scans users’ URL links in order to detect malicious activity, thereby preventing your users’ security from being compromised. When a URL is received via email, Advanced Threat Protection will automatically scan the link for malicious behaviour and a reputation check. If the link is found to be malicious, the user will be warned not to open the link. The scans are very quick, but if the user does click on a link during a scan, a message will be shown informing the user that a check is in progress.

Safe Links Policy

Administrators can set up a Safe Links Policy that audits users’ clicks. This is particularly useful for monitoring user behaviour and help administrators focus their training of the necessary staff members who bypass the security warnings.

Safe Attachments

Safe Attachments work in a similar way to URL Detonation by scanning email attachments for malicious behaviour. All attachments go through a real-time behavioural analysis to separate malicious attachments from genuine ones. All identified unsafe attachments will be detonated.

Dynamic Delivery

Dynamic Delivery is the outcome of Microsoft’s efforts to reduce scanning times. Not only are the scanning times reduced but users are also able to open and respond to emails during the scan, meaning there’s no effect on productivity. If the user clicks on an attachment before the scan is complete then a message will be shown, informing the user of the scan. If the attachment is not found to be malicious then it will be reattached and can be accessed as normal. If the link is malicious, then it will be filtered out and the user will be denied access.


Advance Threat Protection is available as an add-on to most Office 365 plans for a small monthly cost. If you would like to benefit from the advanced security measures of ATP, then get in touch.
