Hello, Sunny PA Wong

Welcome to Microsoft Community.

It can be frustrating when settings don’t stay as you want them. Here are a few potential reasons and solutions for why Microsoft Defender’s Web Protection setting might keep turning off on your iPhone:

• Microsoft Defender for Endpoint on iOS uses a local VPN to provide web protection. If the VPN configuration is reset or disabled, it can cause the web protection to turn off. For references, kindly check them here: Configure Microsoft Defender for Endpoint on iOS features - Microsoft Defender for Endpoint | Microsoft Learn
• Resetting your iPhone's network settings can impact the VPN and, as a result, the web protection settings. If you have reset your network settings recently, it may be necessary to reconfigure the VPN settings for Microsoft Defender.

Here are some steps to re-configure your VPN on your Microsoft Defender:

1-> Go to Settings - Search VPN & Device Management - Find if there is a VPN setting for Microsoft Defender - If there is, please try to delete VPN - as shown in the picture:

2-> Then re-download Microsoft Defender - follow the instructions to reopen the MS Defender application. Agree that "MS Defender" wants to add VPN settings - click Allow.

Additionally, if your network experiences changes, such as switching to airplane mode, or if there are interruptions in Wi-Fi and data traffic, or if your phone is in low-power mode, or if you have restarted your iPhone, these factors may cause Web Protection to temporarily lose connection. In such instances, you may need to reconnect or reactivate it.
