AI Pricing Analysis

Pricing Model

Pure per-seat SaaS — you're paying for each user who needs MFA and access security, with the value metric being protected identities. Licensing comes in increments of 10 (under 100 users) or 25 (over 100), so small teams can't just add one seat at a time.

Tier Strategy

Free handles basic MFA for tiny teams or proof-of-concept deployments; Essentials at $3 adds device visibility and policy controls for teams that need more than just a second factor. Advantage at $6 unlocks adaptive authentication and risk-based policies — the trigger is usually when a security team starts caring about contextual access. Premier at $9 is for orgs that need advanced threat detection and privileged access controls, typically driven by compliance requirements.

Competitive Positioning

At $3–$9/user/month, Duo sits in the affordable-to-mid range for identity security — well below Okta's MFA add-ons and competitive with Microsoft Authenticator bundles for orgs not already in the M365 ecosystem. They're clearly targeting security-conscious SMBs and mid-market teams that want enterprise-grade MFA without enterprise-grade pricing.

Growth Lever

Seat count is the primary expansion driver — as headcount grows, so does the bill, and the increment-based licensing means teams often buy ahead of actual need. Feature gating is the upgrade trigger: adaptive policies, device health checks, and SSO capabilities are locked to higher tiers, so teams hit a wall fast once they want anything beyond basic push authentication.
