Duo (Cisco)
live verifiedCisco · Per-user tiered. Free tier covers up to 10 users.
Duo's strength is MFA-first identity assurance, less full IdP feature parity. Often paired with Entra or Okta as an MFA layer rather than as the primary IdP. Premier tier integrates tightly with Cisco's broader security stack.
1.Year-1 TCO breakdown
Representative buyer: 200 employees, 30 SaaS apps, full SAML + MFA + lifecycle automation, 90-day audit retention.
2.The hidden cost category for this IdP
Tie-in to the broader Cisco stack is the silent cost driver. Duo is a Cisco product (acquired 2018); the full security value comes from integration with Cisco's wider platform (Cisco XDR / Security Cloud), which is separately licensed — SecureX, the prior free integration layer, reached end-of-life in July 2024. Standalone Duo is the MFA-and-SSO entry point; expanding to the full Cisco security stack adds significant cost. Buyers who want only the IdP function may find Duo overpriced for what it does without the broader Cisco ecosystem.
3.Migration cost out of Duo (Cisco)
The simplest exit in this cohort on the identity side — Duo's SAML is standard and SCIM is straightforward, and there is no proprietary automation layer to rebuild. The real cost is MFA re-enrolment, which is a change-management problem rather than an engineering one: every user re-enrols a factor, and the helpdesk absorbs the spike. If you have leaned on Duo's device-health posture checks, those policies also have to be re-expressed in whatever the target IdP uses for device trust.
4.The negotiation lever
Cisco bundling. If you already buy Cisco networking or security products, Duo is negotiated into the Enterprise Agreement rather than as a standalone line, and that is where the leverage is. Standalone Duo buyers are negotiating against published list rates with little room. Worth pricing explicitly: the Premier tier at $9 exists largely to integrate with the wider Cisco stack, so if you are not buying that stack, check whether Advantage at $6 covers what you actually need.
