AssetSonar vs VIZOR for Schools

AssetSonar

EZO's IT-asset product, and the rare asset tracker that publishes a per-asset price and includes a genuine service desk at the higher tier — metered by the one number a 1:1 district has most of.

Where AssetSonar is strong

• ● It publishes real per-asset prices instead of gating every number behind a demo — $0.75 per asset per month for ITAM and $1.08 for ITSM — which makes a district budget line something you can build without a sales call.
• ● Unlimited agents on both plans, so adding technicians, building secretaries or a summer help-desk aide never changes the bill.
• ● The ITSM tier is a real service desk, not a ticket list: request and incident management, problem and change management, a service catalog, multi-channel intake, automated routing, multi-step approvals, SLA policies with business hours and escalation, a knowledge base and a self-service portal.
• ● Custody features deeper than most trackers — check-in and check-out, automatic checkouts, automatic custody transfer, reservations and an availability calendar.
• ● Genuine discovery breadth for a commercial tracker: agent-based discovery, network discovery, MDM integrations, barcode and QR scanning, and RFID tagging.
• ● Procurement and service done properly — purchase orders and requests with multi-tier approvals, vendor management, warranty integration, service triage, and scheduled and recurring maintenance with automated reminders.

What to check before you buy

• The meter is your fleet. At a per-asset rate, a 1:1 district is billed on the number it has most of, and every Chromebook you add is a line item forever.

  Basis: Vendor pricing page quotes ITAM and ITSM as per-asset-per-month rates.

• Packages start at 100 assets, so the smallest sites pay a floor rather than what they use.

  Basis: Vendor pricing FAQ: AssetSonar packages start from 100 assets, with volume-based discounts for higher volumes.

• The help desk is the upgrade. SLA management, the service catalog, the self-service portal, the knowledge base, problem and change management and the CMDB are all marked ITSM-only in the vendor's own comparison table — the difference between $0.75 and $1.08 per asset per month.

  Basis: Vendor's published ITAM-versus-ITSM plan comparison table.

• Software asset management is a third line item on top of either plan, at $5 per asset per year.

  Basis: Vendor pricing FAQ describes Advanced SAM as an add-on available with both ITAM and ITSM plans.

• No SIS or rostering integration — no OneRoster, Clever, ClassLink, PowerSchool, Infinite Campus or Skyward anywhere in EZO's connector catalog, which covers MDM, identity and procurement systems.

  Basis: Absent from EZO's published integrations listing for AssetSonar.

• No student, guardian or enrollment concepts. Checkout is employee custody, so a transfer, a withdrawal or grade rollover is invisible unless someone edits the record.

  Basis: The product's data model tracks assets and users; the custody features are documented as employee check-in and checkout.

• No parent e-signature on a device agreement, no student fee assessment, no family balances, and no funding-source or grant dimension for ESSER, Title or E-Rate reporting.

  Basis: Absent from EZO's documented feature set and plan comparison.

• Device connectors are ingest-oriented. The MDM integrations import device state into AssetSonar; nothing pushes a reviewed set of changes back, so an OU move or disabling a stolen Chromebook stays manual in Google Admin.

  Basis: EZO's integration listing describes MDM connectors as importing device data, with no write-back workflow claimed.

VIZOR for Schools

A K-12 edition of Vector Networks' IT asset management suite, focused on Chromebook and 1:1 device tracking with deep bidirectional Google Admin integration, an optional service desk, and software license management.

Where VIZOR for Schools is strong

• ● The most automated Google Admin write-back in the K-12 field: real-time bidirectional integration that assigns organizational units from attributes like AUE date, manufacturer, or assignee grade, updates custom annotated fields, and disables or deprovisions devices.
• ● Bulk Powerwash, including rule-driven automation such as powerwashing a loaner Chromebook the moment it is returned. No other product in this comparison does this, Chalk included.
• ● Warranty information for Dell and Lenovo devices is populated automatically rather than typed in — the strongest warranty automation among these vendors.
• ● Self-service portals for several distinct audiences — teachers, principals, librarians, students, and families — with school-scoped roles.
• ● SIS synchronization that brings in students, teachers, staff, and parents, so family contact data is present for return and damage notices.
• ● Repair cost calculation with chargeback to students or families, plus automatic email notification to students, families, and teachers.

What to check before you buy

• Closed source and license-based, with no publicly documented option to run and inspect the software independently of the vendor.

  Basis: vendor site publishes no source availability or open-source licensing

• No public pricing. Cost depends on which editions you buy, and the site directs every buyer to a calculator or a demo.

  Basis: vendor site publishes no price list

• Capability is split across editions — Chromebook management, ServiceDesk, and Software License Management are separately named products — so help desk is a purchasing decision rather than something included.

  Basis: vendor site lists these as distinct named editions

• Google Admin write-back is rule-driven and real-time, which is fast but offers no documented preview-and-approve step before a device state changes in the live tenant.

  Basis: vendor describes real-time automation with no staged change-set review

• Automatic warranty population is documented for Dell and Lenovo specifically, so districts on other hardware get less benefit from it.

  Basis: vendor names Dell and Lenovo as the auto-populated manufacturers

• Barcode support is described in terms of integrating with barcode scanners rather than a named native mobile app, so hallway scanning may depend on hardware rather than a phone in a technician's pocket.

  Basis: vendor Chromebook page describes barcode scanner integration; no native mobile app is named on the vendor site

• No purchase order and receiving workflow or managed funding-source tracking is documented for the schools edition, though PO data can be linked.

  Basis: absence in vendor K-12 feature documentation

• VIZOR consumes SIS data but does not serve a OneRoster API or act as an identity provider for the district.

  Basis: vendor documents SIS synchronization as an inbound integration only

How Chalk compares with VIZOR for Schools →

The third option: Chalk

If you are weighing AssetSonar against VIZOR for Schools, Chalk belongs on the same shortlist. It is the open-source K-12 IT stack: device inventory that fills itself in from Google Admin, Intune, and Jamf against a roster synced from your SIS, a 1:1 circulation desk with agreements and fees, repairs with parts and costs, a help desk that already knows who is asking, and a built-in SAML/OIDC identity provider.

• ✓ Self-host it free forever under AGPL-3.0 — the entire feature set, one binary, your infrastructure — or use the hosted version, priced by fleet size with no per-seat or per-student fees and the price ladder published.
• ✓ Built only for K-12: students, buildings, custody, funding sources, and ChromeOS auto-update expiration are native concepts, not custom fields.
• ✓ Writes back to Google Admin as a reviewed diff — every OU move, disable, and deprovision previewed before it executes — and serves a OneRoster 1.1 API so other district systems can pull the roster from Chalk.
• ✓ Fees are assessed and tracked without touching payment cards, keeping the asset system out of your PCI scope.
