Hi MrVjjjv,

For help with the security of your iPhone, be sure you don't have any unauthorized modifications as this can cause security vulnerabilities. You can find out more from the article here: Unauthorized modification of iOS can cause security vulnerabilities, instability, shortened battery life, and other issues

Additionally, you started from a good resource that explains what Wi-Fi assist does. About Wi-Fi Assist

You can also view helpful information here: How Apple devices join Wi-Fi networks

The feature for Wi-Fi assist doesn't cause a security issue. However, if you join an unknown or unsecured public network you can have issues. The information below found here can assist with identifying when that type of connection has been made: Recommended settings for Wi-Fi routers and access points

"About privacy and security warnings on your device

If your Apple device shows a privacy warning or weak-security warning about a Wi-Fi network, that network could expose information about your device.

• If you administer the Wi-Fi network, we recommend that that you update the settings of your Wi-Fi router to meet or exceed the security standards in this article.
• If you don't administer the Wi-Fi network, you can bring the recommended settings in this article to the attention of the network administrator."

If you have additional concerns, check out the steps here and reach out to Apple Support directly to further assist. Use the built-in security and privacy protections of iPhone
