Choose Duo when authentication and device trust are the whole job; choose Okta for enterprise-wide identity management. Duo can run as an MFA factor inside Okta.

Ratings: Duo: G2 4.5/5 · Okta: G2 4.5/5, verified August 2026

Duo vs Okta at a Glance

Duo secures the login and the device behind it, while Okta manages the broader identity and access management (IAM) lifecycle.

Overview of Duo

Duo is Cisco's MFA and device-trust platform. Cisco sells it within the Cisco User Protection Suite. It secures the login itself with phishing-resistant factors and passwordless authentication. It also provides device health checks and a hosted single sign-on identity provider. Duo does not document native access certification, entitlement management, or access request workflows.

Key features:

• Phishing-resistant MFA: Verified Duo Push adds a code entry to push approvals, and Proximity Verification uses Bluetooth Low Energy to block adversary-in-the-middle attacks.
• Device trust without mobile device management (MDM): Trusted Endpoints separates managed from unmanaged devices and can block the unmanaged ones, using the Duo Desktop agent rather than a third-party MDM.
• Duo SSO: A hosted Security Assertion Markup Language (SAML) 2.0 and OpenID Connect (OIDC) identity provider that works with existing Active Directory or Google Workspace credentials.
• Cisco Identity Intelligence: Cross-identity visibility, posture management, and threat detection. It replaces the deprecated Duo Trust Monitor as the console where admins review identity risk.
• Hybrid coverage: The Authentication Proxy brings MFA to Remote Authentication Dial-In User Service (RADIUS) and Lightweight Directory Access Protocol (LDAP) systems. Duo Network Gateway reaches on-premises apps without a VPN.

Ideal for: small and mid-market teams that want strong authentication and device trust with a self-serve rollout, especially in hybrid or legacy-heavy environments.

Overview of Okta

Okta is a workforce IAM platform covering SSO, adaptive MFA, a universal directory, lifecycle management, and identity governance. The Okta Integration Network lists more than 8,000 pre-built integrations, and no-code Workflows automate onboarding and offboarding. Okta requires more setup and administration than an MFA-only deployment needs.

Key features:

• Broad SSO coverage: 7,810 of those integrations cover SSO, plus Access Gateway to extend sign-on to on-premises apps without code changes.
• Lifecycle Management: Bidirectional SCIM (System for Cross-domain Identity Management) provisioning and deprovisioning, with 935 Lifecycle Management integrations in the catalog.
• Okta Identity Governance: Access certification campaigns, entitlement bundles, and access request approvals with centralized reporting.
• Adaptive MFA and FastPass: Phishing-resistant factors including FastPass, security-key and passkey authentication through the FIDO2 WebAuthn standard, and smart cards, with device posture signals from Okta Verify.
• Identity Threat Protection: AI-driven detection of identity risk signals across the Okta tenant. Security teams get those signals without running a separate detection tool.

Ideal for: mid-market and enterprise teams consolidating identity, lifecycle, and governance onto one platform across a large app estate.

Side-by-Side Feature Comparison

The products differ in their phishing-resistant MFA methods, the direction user accounts sync, the device management each expects, and whether governance is built in.

Capabilities verified from Duo and Okta documentation, August 2026.

Device management is where the two diverge most concretely: Okta's Desktop MFA expects devices joined to a directory with an MDM behind them, while Duo can establish the same trust with its own desktop agent.

Pricing

Duo publishes four plans; Okta publishes three priced suites plus two quote-only tiers. Okta's adaptive MFA arrives at $14 on Core Essentials, against $6 for Duo Advantage. Core Essentials also carries lifecycle management, which Duo has no equivalent for, so the comparison is not like for like.

Duo:

• Duo Free: $0 for up to 10 users; strong MFA and the Duo Mobile authenticator app.
• Duo Essentials: $3/user/month; phishing-resistant MFA, passwordless, SSO, and Trusted Endpoints.
• Duo Advantage: $6/user/month; adds Risk-Based Authentication, Active Directory Defense, Cisco Identity Intelligence, Duo Passport, and Session Theft Protection.
• Duo Premier: $9/user/month; adds VPN-less remote access to private resources and device trust with an endpoint protection check.

Okta Workforce Identity:

• Starter: $6/user/month, billed annually; SSO, MFA, Universal Directory, and 5 Workflows.
• Core Essentials: $14/user/month, billed annually; adds Adaptive MFA and Lifecycle Management.
• Essentials: $17/user/month, billed annually; adds Access Governance, Privileged Access for 2 admins, and 50 Workflows.
• Professional and Enterprise: quote only; add Device Access, Identity Security Posture Management, Identity Threat Protection, API Access Management, and Access Gateway.

Rates come from Duo's pricing page and Okta's pricing page. All pricing information verified August 2026.

Gotchas:

• Okta: all suites are billed annually with a $1,500 annual contract minimum; no month-to-month option is listed.
• Okta: Identity Governance is unavailable on Starter and Core Essentials and included from Essentials up; Identity Threat Protection is a paid add-on on Core Essentials and Essentials, and unavailable on Starter.
• Duo: licenses are purchased in increments of 10 below 100 users and increments of 25 above.

For very small teams, the purchase increments and Okta's annual minimum shape the bill more than the per-user rate does.

What Users Say

Duo and Okta score nearly identically across the review platforms. Reviews praise Duo for simple deployment and Okta for its broader capabilities, while noting the added cost and administration that come with Okta.

• Duo: rated 4.7/5 on Gartner Peer Insights, where reviewers describe authentication proxy deployments completed in a day, a simple management dashboard, and easy user management through an Active Directory connection.
• Duo: recurring complaints are push notification delays on weak connections, painful device migration when users change phones, and console friction when configuring granular access policies.
• Duo: on-premises estates hit a coverage gap; the Windows Logon client covers RDP, console, and UAC elevation but not non-interactive logons such as scheduled tasks, service accounts, and drive mappings, and PowerShell and SSH coverage needs a separate component on the Advantage or Premier plan.
• Okta: Workforce Identity is rated 4.6/5 for Access Management on Gartner Peer Insights; reviewers credit SSO and automated provisioning and deprovisioning with cutting manual hours and closing offboarding gaps.
• Okta: pricing is the most common complaint on all three review platforms; licensing scales with headcount, and reviewers report extra costs for some features.
• Okta: leaving requires teams to rebuild SAML SSO configurations across the app estate.
• Both: MFA recovery after a lost or replaced device is a weak point across the category.

User sentiment sourced from G2, Capterra, Gartner Peer Insights, and Reddit as of August 2026.

The divergence is less about quality than about where the friction sits. Duo's complaints mostly cluster at the edges of a system that installs quickly: a delayed push, a phone swap, a policy screen that fights back. The non-interactive logon gap is the exception, and it is a coverage and licensing question rather than a friction one. Okta's complaints sit at the center, in the license spend and the administrative load that come with running identity for the whole app estate. Teams choosing between them are largely choosing which of those two problems they would rather own.

When to Choose Duo vs Okta

The choice depends on this year's identity roadmap.

Choose Duo if you need:

• Phishing-resistant MFA as the primary requirement
• MFA coverage for hybrid infrastructure: RADIUS, LDAP, VPNs, and Windows logon
• A self-serve rollout
• An authentication layer that can slot into an existing Okta tenant

Choose Okta if you value:

• A single platform for workforce identity
• No-code Workflows for joiner-mover-leaver automation
• Access certifications, entitlement management, and access request approvals

The deciding question is whether the work stops at the login or continues into account lifecycle and access reviews. For teams already running Okta, the honest third answer is often to run both.

How Duo and Okta Work with Siit

Okta is a native Siit integration. From a Siit workflow or request side panel, admins can reset a password, suspend or activate a user, add or remove group membership, and assign apps in Okta without leaving the request. The same actions are available through Siit's IT Agent.

Siit does not integrate directly with Duo, so Duo enrollment and authentication issues reach the right team through Siit's native Slack and Microsoft Teams integrations. Siit reaches 500+ connectable apps across identity and devices, as well as HR and finance, with Okta actions available inside a request.
