Editor's takeCisco delivers SSO through Duo, which can act as an identity provider or federate with Active Directory and Okta. Gartner named it the sole Customers' Choice for access management in 2026, with 98% of reviewers recommending it. Pricing stays transparent, running from a free 10-user tier up to $9 per user per month on Premier.

Is Cisco Duo SSO FedRAMP authorized?

Yes. Duo offers a FedRAMP Authorized, FIPS-compliant solution delivered through the DHS CDM program, and it also maps to CMMC, NIST CSF, and ISO requirements.

How much does Cisco Duo SSO cost?

There is a free tier for up to 10 users. Paid plans run from Essentials through Premier at $9 per user per month, billed monthly or annually.

The evidence: 6 criteria, 3 penalties (−0.11 points)
9.1
Product Capability & DepthLooked for: Whether the product lets people sign in once and reach many apps using modern, standards-based methods.Cisco delivers SSO chiefly through Duo, a cloud-hosted identity provider supporting SAML 2.0 and OIDC, inline enrollment, self-service device management, passkeys, and Duo Push. It integrates with Active Directory, Okta, and PingFederate and layers adaptive policy and endpoint verification on top of logins. Cisco also embeds SAML SSO natively across Unified Communications and contact-center products.duo.comduo.comcisco.com
9.4
Market Credibility & Trust SignalsLooked for: Independent recognition, verified customer reviews, and standing among analysts and buyers.Cisco Duo was named a Customers' Choice in the 2026 Gartner Peer Insights Voice of the Customer for Access Management, standing alone in that quadrant with a 4.8/5 rating and 98% of reviewers recommending it. In the User Authentication report Duo posted 97% willingness to recommend and 4.7/5 for Product Capabilities. Cisco's global scale reinforces trust.duo.comduo.com
9.0
Usability & Customer ExperienceLooked for: How smoothly users sign in once and how easily admins set the system up and run it.Once authenticated, users switch between Cisco applications without re-entering credentials for the session, cutting password fatigue and resets. Cisco describes its UC SSO implementation as straightforward and quick to set up. Duo emphasizes access without slowing users down and self-service enrollment. Gartner reviewers gave Duo's Deployment Experience 4.7/5.cisco.comdeveloper.cisco.comduo.com

Value, Pricing & TransparencyLooked for: Whether pricing is public, easy to understand, and fair for the capabilities delivered.Cisco Duo publishes transparent per-user pricing: a Free tier (up to 10 users), Essentials, Advantage, and Premier at $9/user/month, billed monthly or annually. SSO is included from the Essentials plan upward, alongside MFA, passwordless, and Duo Directory. Third-party trackers confirm no hidden seat-band tiers.duo.comcostbench.comcapterra.com
9.3
Security, Compliance & Data ProtectionLooked for: Whether the login system meets recognized security standards and protects credentials and data.Duo offers a FedRAMP Authorized, FIPS-compliant solution delivered via the DHS CDM program and helps meet CJIS, CMMC, NIST CSF, and ISO requirements. Cisco's Trust Portal publishes SOC, FedRAMP, ISO, and C5 audit reports. SSO pairs with phishing-resistant MFA, adaptive access, and endpoint verification, and tokens are digitally signed so apps exchange only tokens, never user credentials.duo.comcisco.comcisco.com
9.0
Integrations & Ecosystem StrengthLooked for: How widely the SSO connects to other identity providers, apps, and Cisco's own product portfolio.Duo SSO can act as both identity provider and SSO platform, or federate with existing IdPs like Active Directory, Okta, and PingFederate, reducing the need for multiple providers. Native SAML SSO spans Cisco Unified Communications Manager, Unity Connection, contact-center, and OS Administration tools, and developer APIs let custom apps consume SSO tokens via DevNet.duo.comdeveloper.cisco.com

PricingFree up to 10 users (no SSO); Essentials with SSO from $3/user/month

Editor's takeDuo's reputation for being easy to deploy is not just marketing. G2 reviewers score its setup at 9.0 versus 8.3 for Oracle SSO, and Reddit sysadmins independently call it the easiest identity tool they have used. The tradeoff is depth, since it relies on an external directory like Active Directory for full lifecycle management rather than replacing one outright.

Does Duo's free plan include SSO?

No. The Free edition covers up to 10 users but excludes hosted SSO. Single Sign-On starts on the Essentials plan at $3 per user per month.

Is Duo SSO FedRAMP authorized?

Yes. Duo Federal editions are FedRAMP Authorized and align with NIST SP 800-63-3 guidelines, and Duo Mobile is FIPS 140-2 compliant by default.

Product Capability & DepthLooked for: We evaluate the solution's ability to function as a comprehensive Identity Provider (IdP), supporting standard protocols (SAML, OIDC) and user lifecycle management.Duo SSO functions as a cloud-hosted IdP supporting SAML 2.0 and OIDC, with features for passwordless authentication and inline user enrollment. However, it primarily acts as an authentication layer rather than a full lifecycle management platform, often relying on external directories like Active Directory for the primary source of truth.duo.comduo.comduo.com

9.1
Value, Pricing & TransparencyLooked for: We examine public pricing availability, tier structures, and the inclusion of critical features in lower-cost plans.Duo offers highly transparent pricing with clearly defined tiers: Free (10 users), Essentials ($3/user/mo), Advantage ($6/user/mo), and Premier ($9/user/mo). SSO capabilities are included starting at the affordable Essentials tier.duo.comduo.comduo.com
9.4

It supports strict device health checks and trusted endpoint verification.duo.comduo.com

Integrations & Ecosystem StrengthLooked for: We look for the breadth of pre-built connectors, API capabilities, and integration with major infrastructure providers.Duo provides hundreds of out-of-the-box integrations and generic SAML/OIDC connectors for custom apps.

Editor's takeAuthX targets shared workstations in hospitals and factories, a gap most generic SSO tools skip. Its RFID badge login cuts sign-in time from 14 seconds to under 2, which explains the near-top usability score. The catch is scale, since its review count and integration library trail bigger rivals like Okta.

How fast is AuthX badge login?

Tap & Go badge login cuts sign-in time from an average of 14 seconds to under 2 seconds.

PricingAll-inclusive license, around £13.94/user in public sector deals

Editor's takeThales stands out by pricing hardware and software tokens into one license, avoiding a common industry surcharge. The App Gateway extends SSO to legacy apps that don't support SAML or OIDC. Reviewers still flag the interface as confusing for some integrations.

What makes Thales SSO different from competitors?

Its Smart SSO applies access policies based on real-time session risk, and its App Gateway extends single sign-on to legacy apps that don't support SAML or OIDC.

Is Thales SSO pricing transparent?

PricingFrom $1,000/yr per shared app (AWS Marketplace)

Editor's takeCerby extends identity providers like Okta and Azure AD to apps that never built native SSO support, automating 2FA enrollment and password rotation for accounts that otherwise sit outside IT's control. Backing from Okta Ventures and Salesforce Ventures, plus a clean SOC 2 Type II audit with no noted exceptions, signals real enterprise trust. AWS Marketplace lists specific per-app pricing, from $1,000 yearly for shared apps to $7,000 for standard apps, giving buyers a clearer cost picture than most enterprise identity tools.

How much does Cerby cost?

Pricing is per application. AWS Marketplace listings show $1,000 per year for shared apps and $7,000 per year for standard apps.

Does Cerby replace an identity provider like Okta?

No. Cerby complements existing identity providers like Okta and Azure AD by extending their SSO and lifecycle management to apps that lack native support.

Editor's takeOmniDefend's niche is bridging biometric hardware with SSO, supporting devices like Fujitsu PalmSecure palm vein scanners that most cloud-only identity providers ignore. Its password-fill feature extends single sign-on to legacy desktop apps that never supported SAML or OIDC. The setup process asks more of IT admins than typical SaaS tools, requiring manual registry edits to deploy the browser extension.

Does OmniDefend support biometric hardware like palm vein scanners?

Yes. It natively supports Fujitsu PalmSecure scanners and Windows Biometric Framework compliant fingerprint sensors, per its Chrome extension listing.

Is OmniDefend pricing published?

No. Pricing requires contacting the vendor directly, with no public tiers listed, according to a Slashdot comparison.
