Explanation

The port that must remain open for a secure website is port 443. Port 443 is used by Hypertext Transfer Protocol Secure (HTTPS), which is an extension of HTTP that encrypts and authenticates the communication between a web server and a web browser. HTTPS ensures that the data transmitted over the web is protected from eavesdropping, tampering, or spoofing. Therefore, port 443 must remain open for a secure website to function properly.
