What’s ngrok.exe (The ngrok agent gets you online in one line.)? Is it safe or a virus?

ngrok.exe by Ngrok, Inc. is a command-line tool that creates secure tunnels from a local machine to the internet. It allows developers to expose a local server, application, or service running on their computer to the public web by generating a unique URL. This is often used for testing webhooks, APIs, or accessing local development environments remotely. The tool simplifies accessing services behind firewalls or NAT, bypassing complex network configurations, while also providing HTTPS support and monitoring features. Its ease of use and versatility make it a popular choice for developers needing temporary, sharable access to local resources.

What does it mean if someone is the publisher of a PC .exe (executable or process)?

The publisher of an executable is the entity responsible for its distribution and authenticity. Most processes/executables on your PC should be signed. The signature on the executable should have been verified through a third party whose job it is to make sure the entity is who it says it is. Find an unsigned executable? You should consider scanning any completely unsigned .exe on your PC.
