## Benefits of Windows Defender SmartScreen
|
||||
Windows Defender SmartScreen helps to provide an early warning system against websites that might engage in phishing attacks or attempt to distribute malware through a socially-engineered attack. The primary benefits are:
|
||||
|
||||
- **Anti-phishing and anti-malware support.** SmartScreen helps to protect your employees from sites that are reported to host phishing attacks or attempt to distribute malicious software. It can also help protect against deceptive advertisements, scam sites, and drive-by attacks. Drive-by attacks are web-based attacks that tend to start on a trusted site, targeting security vulnerabilities in commonly-used software. Because drive-by attacks don't typically require any interaction, there's nothing to click, nothing to download, the infection is often invisible. For more info about drive-by attacks, see [Evolving Microsoft SmartScreen to protect you from drive-by attacks](https://blogs.windows.com/msedgedev/2015/12/16/smartscreen-drive-by-improvements/#3B7Bb8bzeAPq8hXE.97)

|
||||
|
||||
- **Reputation-based URL and app protection.** SmartScreen evaluates a website's URLs to determine if they're known to distribute or host unsafe content. It also provides reputation checks for apps, checking downloaded programs and the digital signature used to sign a file. If a URL, a file, an app, or a certificate have an established reputation, your employees won't see any warnings. If however there's no reputation, the item is marked as a higher risk and presents a warning to the employee.

## How SmartScreen works when a user tries to run an app
|
||||
## How SmartScreen works when an employee tries to run an app
|
||||
Windows Defender SmartScreen checks the reputation of any web-based app the first time it's run from the Internet, checking digital signatures and other factors against a Microsoft-maintained service. If an app has no reputation or is known to be malicious, SmartScreen can warn the employee or block the app from running entirely, depending on how you've configured the feature to run in your organization.
|
||||
By default, your employees can bypass SmartScreen protection, letting them run legitimate apps after accepting a warning message prompt. You can also use Group Policy or Microsoft Intune to block employees from using unrecognized apps, or to entirely turn off Windows Defender SmartScreen (not recommended).
|
||||
|
||||
### How employees can report websites as safe or unsafe
|
||||
You can configure Windows Defender SmartScreen to warn employees from going to a potentially dangerous site. Employees can then choose to report a website as safe from the warning message or as unsafe from within Microsoft Edge and Internet Explorer 11.
|
||||
|
||||
**To report a website as safe from the warning message**
|
||||
- On the warning screen for the site, click **More Information**, and then click **Report that this site does not contain threats**. The site info is sent to the Microsoft feedback site, which provides further instructions.
|
||||
|
||||
**To report a website as unsafe from Microsoft Edge**
|
||||
- If a site seems potentially dangerous, employees can report it to Microsoft by clicking **More (...)**, clicking **Send feedback**, and then clicking **Report unsafe site**.
|
||||
|
||||
**To report a website as unsafe from Internet Explorer 11**
|
||||
- If a site seems potentially dangerous, employees can report it to Microsoft by clicking on the **Tools** menu, clicking **Windows Defender SmartScreen**, and then clicking **Report unsafe website**.
|
||||
|
||||
## Viewing Windows Defender SmartScreen anti-phishing events
|
||||
When Windows Defender SmartScreen warns or blocks an employee from a website, it's logged as [Event 1035 - Anti-Phishing](https://technet.microsoft.com/en-us/scriptcenter/dd565657(v=msdn.10).aspx).
|
||||
|
||||
## Windows Defender SmartScreen on Windows Mobile
|
||||
Windows Defender SmartScreen on Windows Mobile helps to provide anti-phishing protection. If SmartScreen detects malicious content on a site, it can block the site itself or in some cases just specific content on the page. Also available for Internet Explorer 11 on Windows Mobile, is the SmartScreen URL reputation filter, which blocks or warns your employees about suspicious or potentially malicious websites.

# Recommended settings using Windows Defender SmartScreen in your organization
|
||||
|
||||
**Applies to:**
|
||||
- Windows 10, Version 1703
|
||||
- Windows 10 Mobile
|
||||
|
||||
By default, Windows Defender SmartScreen lets employees bypass warnings. Unfortunately, this can let employees continue to an unsafe site or to continue to download an unsafe file, even after being warned. Because of this possibility, we strongly recommend that you set up Windows Defender SmartScreen to block high-risk interactions instead of providing just a warning.
|
||||
|
||||
To better help you protect your organization, we recommend using these Windows Defender SmartScreen Group Policy and mobile device management (MDM) settings.
