 Are you confused on the Microsoft Branding?

Me too.  Below is chart  comparing Defender ATP version Windows Defender.

Don’t I already have a spam filter? 

The spam filter in your email client like Outlook or Gmail is ok for personal emails but not for a business professional.  The email spam filtering platforms listed above are the next level of defense against unwanted and malicious junk email and phishing attacks.   

 While spam is annoying, phishing attacks are devastating to a business.  Employees can easily be duped into conversations with an individual posing as a vendor or client with an ever-so-slightly-off domain or clicking on a well-known brand like Microsoft, FedEx, etc., and they end up handing over their credentials or allowing remote access to a bad actor.   

It is best to incorporate a business grade “email quarantine” solution and “report message” plugins to your Outlook.  The best pair of eyes for malicious activity are your own users.  The “report message” plugin in Outlook, utilized by your users is the first line of defense against bad actors. 

Defender ATP Best Practices according to email spam filter IT support professionals

Defender unfortunately quarantines a lot of legitimate emails in the beginning of your Office 365 email spam filter/quarantine setup experience.  We have provided the URL below for the client to flag those “quarantined” emails if they believe they are legitimate.   

Those flagged emails can be set up to notify directly through 365 Defender, but we believe it’s best that they send an email to your support team to request a review of the email you flagged.  If you need professional help, you can always contact our team at NetworkAntics. 



Above is the link to the quarantine page – it is imperative that each user visit this page at least once a week to review quarantined messages for at least the first 90 days.  Defender ATP may have mistaken critical communication for spam or something malicious.
