Network monitoring, remote access, and connectivity tools
10 programs reviewed · Updated August 9, 2026
Networking software covers everything from diagnosing why a connection is slow to accessing another computer remotely over the internet. Because these tools often need low-level access to network interfaces, publisher trust and open documentation matter more here than in most utility categories.
Remote access tools split into two models: those that route your session through the vendor's relay servers for easy setup behind firewalls, and those that establish a more direct peer-to-peer connection for better performance. The trade-off is usually convenience versus control over exactly how your traffic is routed.
This hub covers network monitors, remote desktop tools, and connectivity utilities, along with guides for common questions such as diagnosing a slow Wi-Fi connection, setting up remote access to a home computer, and understanding what a network scanner is actually showing you.

Reputable tools encrypt the session and require authentication, but any remote access tool is a meaningful target for attackers, so using strong, unique credentials and enabling two-factor authentication where offered is important.
Speed test results are affected by network congestion, the server you're testing against, and other devices on your network competing for bandwidth. Running tests at different times gives a more accurate picture than a single result.
A VPN routes your internet traffic through another network and location. Remote desktop software lets you view and control another specific computer's screen. They solve different problems and are sometimes used together.
