When a web request is made, it uses a structure of requests and responses for effective communication between clients and servers. The message sent by a client to the server is known as an HTTP request. HTTP means HyperText Transfer Protocol. The request and response, in this case, are in plain text, which means whomsoever is the man in the middle can read everything like websites visited, login credentials, and card details that are sent to the server. To overcome this issue, a revised protocol of HTTP is released which is known as HTTPS, which stands for HyperText Transfer Protocol Secure. HTTPS encrypts the request and response. So, if someone is the man in the middle cannot see anything apart from gibberish.

Most websites now are over HTTPS but if someone is in the middle of your connection or in other words Man in the Middle, an attacker can degrade the service from HTTPS to HTTP to read the gibberish. So to ensure that no one does that, you can install a browser Extension. The extension will make sure your connection is over HTTPS.

The Extension is HTTPS Everywhere, just search for the extension continued by your browser name. After installing the extension. Click on the extension and switch on the below-mentioned options.

If the server does not have HTTPS i.e. SSL certificate. The HTTPS Everywhere extension will display a message something like below. Do not worry it is not a problem or error, just choose one from the available option. Opening an insecure page means the extension will remember your choice and will not show a warning every time you open this site. But if you choose the Open insecure page for this session only will open the page as HTTP for only this session.
You can access the website after this warning just be aware if you are typing your credit card details or login credentials.

VPNs - Virtual Private Network

According to Wikipedia, A virtual private network (VPN) extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Applications running across a VPN may, therefore, benefit from the functionality, security, and management of the private network.

In simpler words, if VPN is set up for your device, the connection will be sent to that Virtual Network before sending it to the server you requested for. And the server will not use your IP, the virtual network's IP will be visible and also all the connections between your device and the VPN are encrypted so no one can read that message.
If you use VPN, then the VPN is Man in the Middle. So, you need to read their logging policy in detail.
