Best IT Asset Inventory Tools of 2026, Ranked on Coverage and Data Trust
Seven asset inventory and asset management tools for security and IT teams, scored 0-100 on seven published criteria. Compiled from vendor documentation and pricing pages.
For a security team that needs one trustworthy record of every asset across many existing tools, Axonius is our top pick (76 out of 100). It leads on source coverage and correlation, but it does not publish prices and needs an adapter configured for each source. JupiterOne (73) is the pick for graph queries with published prices, and runZero (72) for agentless network discovery.
Which IT asset inventory tool ranks first in 2026?
Scores come from seven weighted criteria. Axonius ranks first overall, and loses four of the seven criteria to another tool. The table shows each score; the methodology page shows the math.
Coverage and trust score, editorial assessment, 0-100. Survey date: September 2026.
Coverage and trust score (editorial assessment, 0-100). It measures how completely and reliably a tool can tell a security or IT team what assets exist, who owns them and what state they are in. It is not a measure of overall product quality: service management platforms and lifecycle tools score lower here because inventory accuracy is one part of what they do.
Ownership changes in 2026: ServiceNow acquired Armis (April); Dragos acquired runZero (September). Scores reflect product documentation reviewed in September 2026.

ServiceNow CMDB: the system of record the ranked tools feed. Axonius reads ServiceNow CMDB tables and can create, update or remove ServiceNow assets.
We score a vendor only when its public pages document every one of the seven criteria. These four did not, on the pages we read, so they are listed with what is published and no score.
Source coverage: More than 1,200 adapters, and the platform page lists devices, identities, SaaS, software, cloud, IoT and OT as covered asset types.
Correlation and deduplication: Reconciling what each connected tool reports into one record per asset is the core of the product.
Data freshness: Data refreshes on each discovery cycle, so freshness depends on cycle frequency and on each source tool.
Query and reporting: Query Wizard plus a natural language interface across the whole asset footprint.
Remediation and write-back: Enforcement actions include creating, updating and removing assets in ServiceNow; ticket workflows themselves run in the ITSM tool.
Deployment effort: Each adapter needs API access and credentials, so time to full coverage grows with the number of tools connected.
Price transparency: No price published. The site offers "Get Pricing" through sales.
JupiterOne · 73 / 100
Source coverage: 200+ integrations across security, IT, DevOps and HR tools; OT and IoT devices are not documented on the pages we reviewed.
Correlation and deduplication: A security graph maps relationships between assets; entity matching depends on the data each integration supplies.
Data freshness: Updates arrive through integration syncs; sync frequency is not published on the pages we reviewed.
Query and reporting: Graph queries with a pre-built library and natural language questions, plus blast-radius views across relationships.
Remediation and write-back: Alerts and notifications are documented; write-back actions into other systems are not.
Deployment effort: SaaS with API integrations; useful coverage depends on how many integrations a team configures.
Price transparency: Annual list prices published: $25,000, $50,000 and $100,000 tiers by data points.
runZero · 72 / 100
Source coverage: Active scanning, passive discovery and integrations across IT, OT, IoT, cloud, mobile and remote assets; SaaS apps are not covered.
Correlation and deduplication: Profiles each asset against nearly 1,000 attributes and merges integration data into that profile.
Data freshness: Recurring scan tasks plus always-on passive discovery for fragile OT networks.
Query and reporting: Inventory search and reporting, with AI-assisted reporting on the Platform plan.
Remediation and write-back: The ServiceNow integration enriches the CMDB; no enforcement workflow of its own is documented.
Deployment effort: No agents, credentials or appliances required, SaaS, on-premises and air-gapped options, and a free 21-day trial.
Price transparency: Community Edition free for 100 or fewer assets; the Platform plan starts at $5,000.
Lansweeper · 70 / 100
Source coverage: Separate discovery for the network including OT, off-network laptops and cloud; SaaS coverage is limited to AI usage tracking on the pages we reviewed.
Correlation and deduplication: Merges duplicate records on MAC address, serial number and hostname rather than IP address.
Data freshness: Passive detection runs by default alongside scheduled scans.
Query and reporting: Inventory reports and dashboards; less cross-source query depth than graph or aggregation platforms.
Remediation and write-back: Sends inventory into ServiceNow, Jira Service Management, Freshservice and other ITSM tools; no enforcement actions of its own are documented.
Deployment effort: Agentless scanning, an optional agent for remote laptops, and a 14-day trial with no credit card.
Price transparency: Starter and Pro list prices published, billed annually; free up to 100 assets; Enterprise quoted from 10,000 assets.
Armis · 69 / 100
Source coverage: IT, OT and IoT, medical devices and cloud instances, managed or unmanaged; SaaS apps and identities are not documented as asset classes.
Correlation and deduplication: Identification uses an Asset Intelligence Engine with a knowledgebase of over 6.5 billion assets.
Data freshness: Agentless discovery that captures network traffic continuously; the strongest freshness case in this lineup.
Query and reporting: Asset views and dashboards; query depth is not documented in detail on the pages we reviewed.
Remediation and write-back: Pushes enriched data back to the CMDB; prioritization and remediation sit in the separate VIPR-Pro module.
Deployment effort: Cloud platform with no on-premises hardware for the core product; Armis says most customers see an inventory within minutes to hours.
Price transparency: No price published.
Oomnitza · 62 / 100
Source coverage: Hardware, software, SaaS, cloud and AI tools through more than 1,500 data surfaces; OT, IoT and network devices are not documented.
Correlation and deduplication: Reconciles procurement, MDM, EDR and ITSM data into one record per physical asset.
Data freshness: Depends on integration sync; cadence is not published.
Query and reporting: Asset and license reporting; security coverage queries are not documented in detail.
Remediation and write-back: Automates onboarding, refresh, recovery and license reclamation workflows.
Deployment effort: Cloud SaaS; integration setup determines time to value.
Price transparency: No price published.
Device42 · 57 / 100
Source coverage: Agentless discovery from mainframes to cloud containers, SNMP network devices, AWS and Azure; end-user laptops, SaaS and identities are not documented.
Correlation and deduplication: A CMDB fed by continuous scheduled discovery, with fewer third-party sources to reconcile.
Data freshness: Discoveries run continuously on a schedule.
Query and reporting: CMDB views, IP address management and auto-generated dependency visuals.
Remediation and write-back: 30+ integrations including ServiceNow, Freshservice and Jira; no enforcement actions of its own are documented.

Axonius

Top pick: correlated asset inventory across many tools
Coverage is the first question in any asset inventory purchase. The grid shows, for seven asset classes, whether each vendor documents coverage on its own public pages. Axonius documents six of seven classes fully and the seventh partially. runZero and Lansweeper tie at five and a half. Nobody documents all seven.
Axonius ranks first on the weighted total, not on every row. Four criteria go to other tools:
Price transparency: JupiterOne (92) and Lansweeper (90) publish prices; Axonius (15) does not.
Deployment effort: runZero (90) and Lansweeper (86) produce an inventory with less setup. Axonius (60) needs each source tool connected through an adapter.
Data freshness: Armis (88) and runZero (80) watch the network directly. Axonius (78) refreshes on each discovery cycle and is only as current as the tools it reads.
Query and reporting: JupiterOne (88) edges Axonius (86) for relationship queries across its security graph.
These are real trade-offs. A team that needs a fast inventory on a known budget should look at Lansweeper or runZero first.
Do you need a CMDB and an asset inventory tool?
Often, yes. A CMDB such as ServiceNow is the system of record that IT workflows run on. An asset inventory or CAASM tool reads many sources, including the CMDB, works out which records describe the same asset, and shows where the CMDB, the EDR console and the identity provider disagree. Axonius documents create, update and remove actions for ServiceNow assets, so the two are usually deployed together rather than chosen between.
Dragos said runZero will extend asset visibility across existing IT, OT and cloud data inside its xOT platform, with runZero CEO HD Moore leading integration and continuing to serve existing customers.
On our rubric, Axonius scores highest (76 out of 100) for teams that need one correlated record of assets across many existing tools. JupiterOne (73) suits teams that want graph queries and published prices, and runZero (72) suits teams that need agentless discovery of what is on the network.
Is ServiceNow an asset inventory tool?
ServiceNow's CMDB is a system of record for configuration items, populated by ServiceNow Discovery and by Service Graph Connectors. It is not in our ranking: the asset inventory tools we rank feed it rather than replace it. See Works alongside: ServiceNow CMDB.
Which asset inventory tools publish prices?
On the pages we reviewed in September 2026: JupiterOne (annual tiers from $25,000), runZero (free Community Edition for 100 or fewer assets, Platform from $5,000) and Lansweeper (Starter and Pro plans, free up to 100 assets). Axonius, Armis and Oomnitza do not publish prices. Device42 publishes its pricing model but not amounts.
Which tools discover assets without agents?
runZero, Armis, Lansweeper, Device42 and ServiceNow Discovery all document agentless discovery. Axonius builds its inventory by connecting to tools you already run through adapters.
