Usually EDREDR: endpoint detection and response. Security software installed on each computer that watches what happens on that machine. first, because protecting each computer against malware is the more basic need. EDR (endpoint detection and response) or good modern antivirus stops much common malware on laptops and servers, and together with multi-factor authentication, prompt updates and tested offline backups it covers the attacks small companies see most. NDRNDR: network detection and response. Security monitoring that watches the traffic between devices and raises an alert when one behaves like an attacker. (network detection and response) comes next, and it moves up the list when you have a local network with servers, printers, cameras or production machines that cannot run an agent, when a customer contract or NIS2NIS2: the EU's second Network and Information Security directive. The EU cybersecurity law (Directive (EU) 2022/2555) that sets security and incident-reporting duties for many companies. asks you to detect and report incidents, or when you want an independent check that the endpoint tool is not the only witness. You do not have to choose on faith: the NetSenX Free plan covers 3 devices with no time limit, so you can put one agent on a mirror port and see what the network shows before spending money.
