# How do I find old remote-access tools that suppliers left on our servers?

Combine the software inventory with the network traffic. On each server, list installed programs and running services and look for remote-desktop and remote-support tools, VPN clients and agents of remote-management platforms; ask each supplier which tools they installed, when, and whether they still use them. On the network, look for what those tools do even when idle: regular check-ins to the vendor's relay servers, or connections from a cloud address that nobody on your side can explain. Remove what is no longer needed, move what is needed behind your own controlled access path, and change the passwords the supplier knew. NetSenX flags the regular check-ins as beaconing on every plan, and lists outside destinations on rented cloud servers in its review queue, where you confirm them, mark them suspicious or leave them for later. When the agent runs on the server, the alert also names the local program.
