Nessus® Network Monitor provides continuous visibility into the systems and services running on your networks, for unmatched asset insight. From legacy assets to the latest technologies, and from IT to OT, it illuminates blind spots so you can see and protect your entire environment. Nessus Network Monitor offers enhanced OT support – including asset discovery and protocol detection – for passively monitoring industrial control systems (ICS), SCADA systems and other operational technology. This gives security teams a safe and non-intrusive way to discover and monitor sensitive critical infrastructure systems. Nessus Network Monitor also detects new and unmanaged assets – spanning operating systems, network devices, hypervisors, databases, mobile devices, web servers, cloud applications, IoT devices and more.
