SAM — IT definition

SAM (Software Asset Management) is the sub-discipline of ITAM dedicated to managing the lifecycle of software licenses: purchases, deployments, actual usage, renewals, compliance with vendor terms. Its goal: pay for what you actually use — no more, no less — while staying compliant with vendor contracts.

Per Gartner, organizations without mature SAM typically carry 20 to 30 % of software over-spend (unused licenses, redundant purchases, over-licensing) and significant vendor audit exposure, which can run into millions at Microsoft, Oracle, or SAP.

Why SAM has become strategic

Three trends amplified the SAM stakes:

• •Licensing model inflation: per user, per CPU core, per capacity, per feature, per environment... every vendor has its own logic, and the logic changes often.
• •Aggressive vendor audits: Oracle, Microsoft, IBM, SAP, Autodesk run recurring commercial audits. True-ups can represent years of license fees.
• •The [SaaS](/en/glossary/saas) explosion: traditional SAM dealt with installed software. Most software spend is now SaaS subscriptions, managed differently.

Key SAM processes

• •Continuous inventory: what do we own, where is it installed, who actually uses it?
• •Entitlement reconciliation: cross purchased usage rights (contracts) with installation and effective use.
• •Compliance management: avoid both under-licensing (audit exposure) and over-licensing (waste).
• •Continuous optimization: redeploy unused licenses, downgrade, negotiate renewals.
• •Audit readiness: produce compliance evidence on demand.
• •Purchase governance: centralize purchase decisions, prevent team-level duplicates.

SAM vs SaaS Management

A useful distinction:

• •Traditional SAM: focuses on installed software (Windows, Oracle DB, Adobe Creative, SAP) with perpetual or complex subscription licenses.
• •SaaS Management: focuses on cloud subscriptions (Salesforce, HubSpot, Slack, Notion) with simpler models but a much larger vendor sprawl.

The two are converging under the modern ITAM umbrella, which has to cover all software spend, on-premise and SaaS.

The most audit-active vendors

The vendors most likely to audit — and therefore to prioritize in a SAM program:

• •Oracle: server licenses, Java SE, databases, complex options.
• •Microsoft: Windows Server, SQL Server, Microsoft 365, cloud usage rights.
• •IBM: PVU licenses, complex environments, virtualization.
• •SAP: indirect access, data usage rights.
• •Adobe: , Autodesk: creative or CAD licenses, geographic usage limits.

SAM standards

• •ISO/IEC 19770-1: SAM processes.
• •ISO/IEC 19770-2: software identification tags (SWID).
• •ISO/IEC 19770-3: entitlement description schema (ENT).

ISO 19770-1 certification is leverage in front of vendor auditors: it demonstrates governance maturity around licenses.

SAM tools

Three main families:

• •Dedicated SAM tools: Flexera One, Snow Software (Flexera), USU, Lansweeper, Aspera.
• •Integrated ITAM suites: ServiceNow SAM Pro, BMC Helix SAAM, Ivanti — SAM bolted onto ITSM.
• •SaaS Management platforms: Productiv, Zylo, BetterCloud, Torii.
• •Live asset graph platforms: Kabeen — unified view of applications, licenses, usage, and cost.

Benefits of a SAM program

Per the Gartner SAM Maturity Survey, a mature program delivers:

• •20 to 30 % savings on software spend: in year one.
• •A 60 to 80 % reduction in true-up risk: during audits.
• •Faster onboarding: of new users or services (licenses are already available).
• •Better preparation for change: cloud migration, M&A, restructuring.

Starting a SAM program

1. Build the inventory of vendors and licenses in place — often missing.
2. Map contracts and current usage rights.
3. Measure actual usage: who opens the app, how often, how many licenses are active.
4. Identify quick wins: unused licenses, duplicates, under-licensing to fix.
5. Industrialize: automate usage collection, plug SAM into ITSM and purchase processes.
6. Prepare the first audit from a position of control rather than emergency.
