# Can my small business be hacked without me knowing?

Yes. Attackers who use stolen passwords and the administration tools already on your systems can stay quiet for a long time: nothing breaks, so nobody looks. What gives them away is behaviour, such as a computer contacting a new outside server at regular intervals, one machine connecting to many others, or uploads at night. NetSenX flags beaconing, scanning, lateral movement and unusual outbound data volume on every plan, Free included. It does not see activity that never touches the network.
