Which discovery method is more preferred for end-user devices - agent or agents

[Neha P]

In what conditions is each method preferred, and does agentless discovery generally provide good coverage of devices, considering that devices may be operational at varying times throughout the day?

Agent-based Discovery:

Agent-based discovery is preferred in the following scenarios:
Continuous Monitoring Required – When real-time or frequent monitoring of device configurations, performance, or security compliance is needed.
Deep System Access Required – When detailed information such as installed software, registry settings, or security configurations must be collected.
Highly Secure Environments – When devices operate in a secure or air-gapped network where credentials cannot be frequently shared over the network.
Limited Network Access – When firewall restrictions or network segmentation limit remote access for agentless discovery.
Reliable Connectivity – When devices are constantly online, ensuring the agent can regularly report data.

Agentless Discovery:

Agentless discovery is preferred in the following scenarios:
Rapid Deployment Required – When a quick scan of network assets is needed without installing software on individual devices.
Heterogeneous Environments – When managing multiple device types, including network equipment, virtual machines, and IoT devices that may not support agents.
Minimal Administrative Overhead – When IT teams want to avoid managing, updating, and troubleshooting agents on each endpoint.
Short-term or One-time Audits – When performing periodic IT asset inventory or compliance checks.
Highly Dynamic Environments – When devices frequently change (e.g., BYOD environments or cloud-based workloads).
