Windows Defender SmartScreen is another layer of security added by Microsoft that works to prevent successful phishing attempts. When running your ThreatDefense campaign your users may encounter a red screen when clicking links in your phishing campaign email. 

This screen warns users away from inputting data in your landing page. This will skew your data on which users would have fallen prey to a phishing scam and would benefit from additional training identifying scams and threats. To circumvent Windows Defender you will need to do additional whitelisting of the domain(s) you are sending your phishing campaigns from. 

The process for whitelisting these domains will vary depending on your environment. Check the documentation of your organization's tools for whitelisting options/solutions for Windows Defender. The following steps are only one example of a possible solution.
