Comparison Table
Auvik
SMBCloud-based network mapping and monitoring software.
Topology change detection that turns new discovery results into connectivity deltas for faster network incident triage.
Auvik runs discovery using network access methods that include SNMP polling and neighbor discovery mechanisms that can infer Layer 2 connectivity, which feeds a live topology graph. The product organizes assets and relationships into a navigable network map and supports ongoing refresh so the topology stays current as changes roll through. Integrations connect discovered network details to adjacent systems for wider operational context, and the platform provides admin controls for managing who can view and operate mapping results. Auditability and governance rely on role-based access features that constrain map visibility and change actions.
A key tradeoff is that accurate topology requires reachable device management paths for discovery, so isolated management networks can produce partial maps. A strong usage situation is recurring network change reviews where teams need reliable topology deltas and relationship visibility across VLANs, trunks, and intermediate hops. Auvik also fits environments that want repeatable discovery workflows without building custom discovery pipelines.
- +Live topology updates that highlight connectivity changes between discovery runs
- +SNMP-driven polling plus neighbor inference produces usable Layer 2 connectivity graphs
- +Network map exports support diagram reuse in operational workflows
- +RBAC limits map visibility and discovery management actions by role
- –Discovery coverage depends on device reachability from configured management networks
- –Deep application dependency mapping needs external integration inputs
- –Large multi-site environments require careful discovery scope planning

Best for: Fits when network teams need continuous topology refresh and export-ready diagrams without manual updates.
Lansweeper
SMBAgentless IT asset identification and network mapping platform.
LLDP and SNMP-derived network adjacency feeds an infrastructure relationship graph with topology change detection.
Lansweeper’s discovery coverage emphasizes IP and device identification plus network adjacency via LLDP and SNMP polling. It correlates results across discovery runs into an infrastructure relationship graph that supports topology change detection and dependency-style reasoning. Inventory outputs are usable for configuration item mapping patterns and for exporting network diagrams into formats like Visio topology export. Automation is largely rule-driven through scheduled scans rather than workflow scripting.
A key tradeoff is that deeper application dependency mapping still depends on integration quality and the way endpoints report software and services, not just automatic network correlation. Lansweeper works well in environments that need recurring asset-to-network visibility across hybrid infrastructure and want diagram outputs for change review. It can be less efficient when the primary requirement is live traffic analysis or east-west and north-south traffic mapping based on flow telemetry.
- +SNMP polling and LLDP neighbor discovery build network adjacency
- +Infrastructure relationship graph supports topology change detection
- +Visio topology export helps convert maps into review artifacts
- +Inventory correlation reduces duplicate asset views

How to Choose the Right It Infrastructure Mapping Software
IT teams use it infrastructure mapping software to transform discovery inputs into topology views and dependency graphs that support operational triage and configuration reconciliation. This guide covers Auvik, Lansweeper, Device42, SolarWinds Network Topology Mapper, Paessler PRTG Network Monitor, ManageEngine OpManager, GLPI, BMC Discovery, and Dynatrace, plus Faddom.
Across these tools, the practical differences show up in how each product performs topology refresh, how it turns relationships into actionable graphs, and how it controls reconciliation into an infrastructure inventory model. The selection criteria in the guide emphasize integration depth, API and automation surface, and admin governance controls where the product stores and refreshes relationship mappings.
IT Infrastructure Mapping Software that produces topology and dependency graphs for inventory and operations
IT infrastructure mapping software collects device and relationship signals like SNMP polling and neighbor discovery data, then generates live topology diagrams and infrastructure relationship views that can be refreshed as the network changes. Auvik is built for topology change detection that converts new discovery results into connectivity deltas, which supports faster incident triage.
For infrastructure relationship mapping that connects configuration and asset records, tools like Device42 focus on keeping topology tracking tied to configuration relationships to support dependency-aware mapping workflows. Other products such as Lansweeper build infrastructure relationship graphs from SNMP polling and LLDP neighbor discovery, then use those graphs to drive recurring network topology maps and asset inventory correlation.
Evaluation criteria for IT Infrastructure Mapping Software
Topology refresh quality determines whether relationship changes become operationally usable artifacts or stale diagrams. Dependency graph usefulness depends on how the tool links discovered connectivity to an infrastructure inventory and then keeps those links consistent across refresh cycles.
Topology change detection that creates connectivity deltas
Auvik turns new discovery results into connectivity deltas so network incidents can be triaged against what changed since the last run. SolarWinds Network Topology Mapper also refreshes diagrams with automated change detection across mapped network relationships.
Network adjacency building from SNMP polling and neighbor discovery
Lansweeper builds an infrastructure relationship graph using SNMP polling plus LLDP neighbor discovery. Auvik also uses SNMP-driven polling plus neighbor inference to produce usable Layer 2 connectivity graphs.
Graph-based dependency visualization that stays navigable for ops
Faddom converts multiple discovery inputs into a navigable infrastructure relationship model that supports graph-based dependency visualization. GLPI focuses on relationship management workflows that connect assets, documents, and tickets while relying on extensibility for the rest of the model.
Reconciliation workflows that map discovered assets into inventory relationships
Device42 ties topology visualization to configuration item relationships and includes reconciliation workflows for mapping discovered assets into an infrastructure inventory model. BMC Discovery uses CMDB reconciliation rule control to govern which discovered attributes update configuration items during refresh cycles.
Agent and data intake strategy for hybrid estates

Dynatrace generates dependency graphs from distributed tracing and runtime telemetry, which reduces reliance on network-only discovery for relationship context.
Operational wiring between monitoring signals and topology diagrams
ManageEngine OpManager integrates topology change detection into the network monitoring workflow so mapping drift can be highlighted using collected device status. Paessler PRTG Network Monitor grounds topology views in the same SNMP polling data that drives alerts.
How to choose IT Infrastructure Mapping Software
Selection should start with the refresh and relationship model expected by operations and config management teams. The next fork should be driven by which signals the mapping process must trust, such as SNMP plus LLDP versus CMDB-centric reconciliation versus runtime telemetry.
Pick the refresh loop that matches incident response behavior
If the organization needs connectivity change diffs between runs, Auvik is built around topology change detection that converts new discovery results into connectivity deltas. If the organization needs repeated diagram exports with change visibility across SNMP-managed sites, SolarWinds Network Topology Mapper automates topology refresh cycles with change detection.
Choose the relationship engine based on how adjacency is built
If network adjacency must come from SNMP polling plus LLDP neighbor discovery, Lansweeper uses both to build a network adjacency and infrastructure relationship graph. If adjacency must be inferred into Layer 2 connectivity graphs for triage, Auvik pairs SNMP-driven polling with neighbor inference to produce those connectivity graphs.
Decide whether topology depends on CMDB reconciliation control
If topology refresh must update configuration items using controlled mapping rules, BMC Discovery provides CMDB reconciliation rule control to govern which discovered attributes update configuration items. If topology must stay tied to configuration relationships through reconciliation workflows, Device42 focuses on reconciliation workflows that map discovered assets into an infrastructure inventory model.
Align graph navigation with the dependency questions the team asks
If the main need is a navigable dependency graph that links discovered relationships into a dependency model, Faddom converts discovery inputs into a navigable dependency graph. If the main need is relationship management across tickets and assets inside a CMDB-centric workflow, GLPI relies on plugin-driven CMDB reconciliation and relationship management.
Select the hybrid intake approach based on where truth lives
If topology and dependencies must be derived across mixed estates using both agent-based and agentless discovery patterns, BMC Discovery fits that hybrid requirement. If dependency-aware mapping must tie infrastructure entities to monitored services and runtime traces, Dynatrace generates dependency graphs from distributed tracing and runtime telemetry.
Match topology diagrams to the monitoring workflow that drives operations
If network teams want topology views that match the same SNMP polling stream that drives alerts, Paessler PRTG Network Monitor builds topology views from SNMP and neighbor signals. If network operations need mapping drift highlighted as part of the monitoring workflow, ManageEngine OpManager ties topology change detection to collected device status.
Who needs IT Infrastructure Mapping Software
IT infrastructure mapping software is for teams that must turn discovery inputs into topology diagrams and dependency views that stay current as networks change. The strongest match depends on whether topology changes must become connectivity deltas, whether reconciliation must be CMDB-controlled, or whether dependency mapping should come from runtime telemetry.
Network operations teams managing frequent topology changes
Auvik supports continuous topology refresh and connectivity deltas between discovery runs, which targets faster network incident triage. ManageEngine OpManager highlights topology drift using collected device status so mapping changes show up inside monitoring workflows.
Hybrid IT teams that must correlate network adjacency with asset inventory
Lansweeper uses SNMP polling plus LLDP neighbor discovery to build an infrastructure relationship graph that supports recurring network topology maps and asset inventory correlation. BMC Discovery supports agent-based and agentless discovery patterns for mixed estates so reconciliation can cover boundary conditions.
ITSM and CMDB teams that require reconciliation control over configuration updates
BMC Discovery provides CMDB reconciliation rule control that governs which discovered attributes update configuration items during refresh cycles. Device42 uses reconciliation workflows to map discovered assets into an infrastructure inventory model tied to configuration item relationships.
Troubleshooting teams that need dependencies tied to runtime behavior
Dynatrace generates dependency graphs from distributed tracing and runtime telemetry so infrastructure entities connect to monitored services and relationship drift can be flagged. Dynatrace dependency mapping depends on available telemetry inputs, which aligns with tracing-heavy environments.
Infrastructure engineering teams creating documentation-ready diagrams with export workflows
Auvik produces export-ready diagrams as topology changes, reducing manual updates for documentation cycles. Faddom produces exportable network diagrams for documentation workflows while also offering graph navigation for dependency views.
Common pitfalls when buying IT Infrastructure Mapping Software
Many failures come from assuming discovery coverage will be uniform or that relationship graphs will reconcile without strict identifier alignment. Other failures come from selecting a topology-only mapping workflow when dependency mapping needs external integration inputs or controlled CMDB update rules.
Overestimating how much topology change detection helps when device reachability is incomplete
Auvik discovery coverage depends on device reachability from configured management networks, so connectivity deltas will only reflect what the management path can reach. SolarWinds Network Topology Mapper coverage depends on SNMP reachability and consistent LLDP neighbor advertisement, which can break change detection in partially reachable segments.
Assuming dependency mapping quality will be high without identifier alignment across systems
Faddom CMDB reconciliation quality depends on identifier alignment across systems, so inconsistent IDs can create relationship gaps. BMC Discovery normalization for CMDB reconciliation requires careful identifier ownership, so misaligned keys can break accurate dependency-focused topology views.
Choosing a network-only mapping workflow when application dependency mapping requires additional inputs
Auvik’s deep application dependency mapping needs external integration inputs, so network-only discovery will not fully answer application dependency questions. Paessler PRTG Network Monitor limits dependency mapping across applications compared with full ITSM CMDB approaches.
Ignoring how governance and reconciliation discipline affect relationship accuracy
BMC Discovery needs high setup and tuning effort for accurate topology change detection, which demands governance discipline to keep reconciliation rules aligned. Faddom advanced governance patterns like granular RBAC may require process workarounds, which can increase operational overhead if access control is strict.
