How Network Device Scanners Work

Network device scanners identify and monitor devices, helping protect your business. They’ll empower your online business by securing your network.

Detecting Devices on a Network

Scanners detect connected devices by sending queries and analyzing responses. Active scanners initiate connection attempts, gathering data from every connected device. Passive scanners listen to network traffic and identify devices without direct interaction, reducing the risk of detection. Agent-based scanners install software on each device to collect data, ensuring comprehensive coverage. Agentless scanners rely on existing data sources, combining information from network management systems, making deployment simpler.

Interpreting Device Data

Scanners analyze device data to understand potential risks. They identify device types, operating systems, and open ports, then cross-reference this data with known vulnerability databases. Real-time monitoring allows for instant detection of new devices or changes, ensuring continuous security. Advanced scanners create device profiles to recognize behavioral patterns and detect anomalies. Customized reports provide actionable insights, allowing you to quickly address potential threats.

Ensuring your network’s security with device scanners is a proactive step towards safeguarding your online business and maintaining customer trust.

Benefits of Using Network Device Scanners
