    The Managed Microsoft Defender Antivirus feature utilizes the Microsoft Defender Antivirus (Non-ATP Microsoft Defender) that is built into Windows 10 (and Server 2016+) and does not require additional licensing. Microsoft Defender is consistently ranked as a top product for protection, performance, and security by AV-Test.  Additionally, cybersecurity experts like Tavis Ormandy (Google Project Zero), Robert O'Callahan (Ex-Mozilla Engineer), Justin Schuh (Google Chrome Team, Former NSA/CIA), and a poll of 3,500+ individuals continue to highlight how the Non-ATP Defender produces solid results while introducing minimal additional attack surface, unlike many 3rd party antivirus products.

    Huntress will not charge extra for Managed Antivirus.

    Managed Microsoft Defender Antivirus Beta is still in its early development stages. By default, Huntress runs in "audit mode"-- we are not making any configuration changes to endpoints. Microsoft Defender status is simply surfaced to the Managed AV Dashboard within Huntress. However, if you are enabling Microsoft Defender for the first time, please keep in mind that you may need to create exclusions for certain business applications to function properly. If you have any issues, please open a ticket with Support here: Contact Us Contact Us
