Device42
Key Info:
Device42 is IT asset discovery and dependency-mapping software for documenting infrastructure, applications and their relationships. It helps technology teams build an inventory of physical, virtual, cloud and network assets and use that data for planning, operations and migration work.
Details
Discovery and infrastructure inventory
Device42 focuses on discovering and documenting infrastructure assets, including devices, virtual environments, networks and cloud resources. Collection accuracy should be measured against a representative estate, not a polished demonstration. Test isolated segments, stale credentials, decommissioned machines and assets with several network identities. Define how often discovery runs and who investigates records that are incomplete or contradictory.
Dependencies and operational mapping
Relationship and application-mapping features can show how systems, services and infrastructure depend on one another. Such maps are useful only when ownership and refresh expectations are explicit. During evaluation, choose one production-like service and verify that the displayed relationships match operational knowledge. Include a firewall or network change, a virtual-machine move and an undocumented dependency to reveal the limits of the model.
Using the data safely
Inventory data can support projects such as migration, security review and capacity planning, but it should not silently replace a controlled configuration-management process. Establish the source of truth for each class of attribute, permitted manual corrections and an exception workflow. Review access controls, agentless or credentialed discovery requirements, integrations, exports, API behaviour, retention and backup before making reports operationally significant.
Evaluation record
Document the approved asset scope, identity rules, required fields, operational owners, source systems, retention, integration boundaries, test exceptions and acceptance measures. Keep fields for pricing, customer size, languages, operating systems and apps blank unless a current official source maps them precisely to the BBS field. Run a time-boxed pilot with a representative asset sample, named data stewards and a written exception log. Compare user actions, audit trail and reports against the present process. At the end, decide whether the product can support the required control model, what configuration or integration work remains, and which measurable result would justify a full rollout. Keep the pilot evidence in a decision record that another administrator can replay, including sample source files, permission settings, expected reports, failure handling, sign-off owners and the plan for migration, training and post-launch review.
