Port 80 is used by Hypertext Transfer Protocol (HTTP). Unencrypted web traffic. HTTP on port 80 carries web page requests and responses. Modern sites redirect port 80 to port 443 (HTTPS).
What Does an Open Port 80 Mean?
A web server is running and accepting unencrypted connections. Most modern sites use this only to redirect to HTTPS. If you see HTTP content instead of a redirect, the site lacks proper SSL configuration.
This port is expected to be open on servers that run this service.

Protect Your Open Ports
If you need services like remote access, use a VPN to create a private encrypted tunnel instead of exposing ports directly to the internet. A VPN also hides your real IP address so port scanners cannot identify your device. Try PureVPN or IPVanish.
