Independent comparison for enterprise buyers. Updated March 2026.
Quick verdict: Cisco Duo and OneLogin overlap on access security but emphasise different layers of it. Cisco Duo, part of Cisco Security, leads on multi-factor authentication, device-trust checks, and verifying endpoint health before access is granted, which makes it a favourite of security teams pursuing zero trust. OneLogin, now part of One Identity, leads on single sign-on breadth, automated identity lifecycle provisioning, and a large application connector catalogue, so the key differentiator is emphasis: Duo optimises for MFA and device posture, OneLogin optimises for SSO and workforce identity management.

Cisco Duo is an access security platform built around multi-factor authentication and device trust. Its core capabilities are a wide range of authentication methods including Duo Push, passkeys, hardware tokens, and biometrics, plus device-health checks that confirm an endpoint is patched and managed before granting access. Higher tiers add single sign-on, adaptive access policies, and the Duo Network Gateway for secure access to internal applications without a full VPN. Duo is consistently praised for how quickly teams can enrol users and reduce account-takeover risk.
OneLogin is a workforce identity and access management platform. Its emphasis is everyday access: single sign-on across more than 6,000 pre-built application connectors, multi-factor authentication, SmartFactor adaptive authentication that scores risk in real time, directory integration, and identity lifecycle provisioning that automatically creates and deactivates accounts as staff join and leave. OneLogin pushes further into joiner-mover-leaver automation than Duo, making it a stronger fit where HR-driven provisioning is a primary requirement.
The practical distinction is which problem you are solving first. Duo is the better starting point when the priority is verifying who and what is connecting, with strong MFA and endpoint posture as the foundation of a zero-trust programme. OneLogin is the better starting point when the priority is consolidating logins and automating the account lifecycle across a large application estate. Both offer SSO and MFA, so the decision rests on where the centre of gravity sits.
Both vendors publish pricing, which simplifies budgeting. Cisco Duo lists tiers from approximately $3 per user per month for core MFA, rising to roughly $6 and $9 per user per month for editions that add single sign-on, adaptive policies, device-health enforcement, and remote access. A free tier covers up to 10 users. Buyers should note that SMS and voice authentication can be billed separately, so heavy reliance on those methods adds cost; push and passkeys avoid that. Pricing verified June 2026; enterprise pricing requires a quote.
OneLogin lists an Advanced plan at approximately $4 per user per month bundling SSO, advanced directory, and MFA, and a Professional plan at approximately $8 per user per month adding identity lifecycle management and HR-driven provisioning. Both platforms deploy as multi-tenant SaaS and can be live within days to a few weeks, with timelines driven by application count and directory complexity rather than infrastructure. OneLogin tiers are typically marketed to organisations of at least 50 users.
Cisco Duo fits naturally into organisations already invested in Cisco networking and security, where shared telemetry and zero-trust integration add value, though it works well as a standalone MFA layer over any identity provider. OneLogin fits organisations that want a single console for authentication and account provisioning across a broad SaaS estate, and that value published, predictable pricing. Where Duo is often layered on top of an existing directory such as Microsoft Entra, OneLogin more often acts as the primary access management hub itself.
Buyers frequently note that Cisco Duo is among the easiest MFA tools to deploy, with end users adopting Duo Push quickly and administrators valuing device-health visibility. Reviewers also point to dependable uptime and clear policy controls. A recurring critique is that costs can climb when SMS or voice authentication is used heavily, and that Duo is not intended to handle full identity governance. OneLogin reviewers consistently highlight its large application catalogue and the value of automated provisioning, and many appreciate transparent pricing relative to larger competitors. Common criticisms include limited branding and customisation on lower tiers and occasional delays in support response. Across both products, sentiment is shaped by the same underlying truth that they emphasise different layers, and organisations choosing on price alone sometimes underestimate the provisioning depth they actually need.
Choose Cisco Duo when the immediate priority is reducing credential-based risk through strong multi-factor authentication and device-trust enforcement, particularly if you are building a zero-trust access programme or already run Cisco security tooling. Duo is the better fit when you want fast user enrolment, endpoint posture checks, and a layer that can sit over an existing identity provider rather than replacing it. Plan separately for identity governance and HR-driven provisioning, since those are not Duo's focus.
Choose OneLogin when the priority is consolidating workforce logins through single sign-on and automating the account lifecycle across a large application estate. It suits mid-market organisations that value a broad connector catalogue, HR-driven provisioning, and published, predictable pricing, and that want one console for authentication and account management. Weigh its smaller market presence and the strategic direction under One Identity ownership, and confirm customisation needs against the limits of the lower tiers during evaluation.
