Comparison

AssetSonar vs SolarWinds Web Help Desk

Two tools districts shortlist for device tracking and IT operations, compared the way a buying committee actually reads them: what each is, what each does well, and what to check before signing. We build Chalk, a third option in this space — that context is worth knowing as you read, and it is why every claim below carries its basis.

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.

Pricing: Published per-asset rates, which is unusually transparent for this category. ITAM is $0.75 per asset per month; ITSM, which includes ITAM, is $1.08 per asset per month; Advanced Software Asset Management is an add-on to either at $5 per asset per year, quoted as $0.42 per asset per month. Packages start from 100 assets, with volume-based discounts stated for 1,000+ assets and Enterprise arrangements by conversation. Agents are unlimited on both plans — EZO's own pricing copy calls out not capping your team with an artificial seat limit. No free tier and no published education discount.

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.

SolarWinds Web Help Desk

A long-serving on-premises help desk with unlimited end users and a fair per-technician price — and a rewritten 2026 release that means a migration project either way.

Pricing: Sold exclusively as an annual subscription, priced per technician per year, with volume discounts applying automatically as technician count rises. End users are unlimited at every tier, so you pay for the help-desk staff rather than for the district. SolarWinds publishes the full price table openly, which is unusual in this market. Note that the older perpetual-license model is historical — third-party sites still quote perpetual figures that no longer reflect how it is sold. A 14-day trial is available. There is no K-12 SKU and no education discount.

Where SolarWinds Web Help Desk is strong

  • Genuinely on-premises and self-hosted, positioned by the vendor as requiring no cloud dependency — which matters to districts with data-residency or board-policy constraints.
  • Unlimited end users at every license tier. You pay for technicians only, which is genuinely favorable for a district with thousands of staff and a handful of techs.
  • Fully published, transparent pricing with no quote gate — competitively unusual.
  • Integrated asset management with ticket-to-asset linking and asset service history, so a technician sees the device from the ticket.
  • LDAP and Active Directory sync plus documented SAML 2.0 SSO against AD FS, Okta, Google, and Entra ID.
  • A modernized 2026 release line — a redesigned interface across 120+ screens, a security-hardened rebuild, and a published forward roadmap including Teams and Slack integrations and AI ticket summaries.

What to check before you buy

  • If you are still on the 12.x line, you have a forced migration ahead: SolarWinds has published End-of-Life dates for versions 12.4 through 12.8, and the replacement is a rewritten application, so it means retraining as well as an upgrade.

    Basis: SolarWinds' own release-history page publishes End-of-Engineering and End-of-Life dates for the 12.x versions and instructs customers to transition to the current release; the 2026.2 notes describe a completely redesigned interface across 120+ screens.

  • No SIS or rostering integration — no OneRoster, Clever, ClassLink, or PowerSchool. Identity comes from LDAP, Active Directory, and SAML only.

    Basis: None appear on SolarWinds' Web Help Desk product pages, education use-case page, or documentation; the documented identity story is explicitly directory-based.

  • No student or guardian concepts. Students appear only as ticket submitters — there is no enrollment, no grade, no guardian, and nothing that reacts to a transfer or a withdrawal.

    Basis: SolarWinds' education page describes students, faculty, and staff purely as end users submitting tickets.

  • No 1:1 device circulation — no due dates on a student's device, no overdue workflow, no e-signed agreement, no loaner pool, and no lost or stolen lifecycle. Asset reservations are the nearest adjacent feature.

    Basis: Web Help Desk's asset management is framed around IT inventory such as projectors and instrumentation; no custody loop appears in the documentation.

  • No student fee assessment or family balances. The parts-and-billing concepts in the product are IT cost accounting, not student charges.

    Basis: No fee, charge, or student-ledger concept appears in the product documentation.

  • No funding-source or grant tracking — nothing to attribute devices to ESSER, Title, or E-Rate.

    Basis: No such concept appears anywhere in the product documentation.

  • No ChromeOS or Google Admin device ingest surfaced. Discovery is network- and directory-oriented, so Chromebooks arrive by import or by hand.

    Basis: No Google Workspace or ChromeOS device-ingest integration appears in SolarWinds' Web Help Desk documentation or integration listings.

  • It consumes SSO but is not an identity provider. It cannot issue SAML or OIDC outward, and cannot give students a portal identity.

    Basis: SolarWinds' authentication documentation configures Web Help Desk as a SAML 2.0 service provider against an external IdP.

The third option: Chalk

If you are weighing AssetSonar against SolarWinds Web Help Desk, 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.

Chalk installs to a populated inventory in about 30 minutes. Self-host free under AGPL-3.0, or let us run it — priced by fleet size, never per seat.
