Best Single Sign-On (SSO) Solutions for Marketing Agencies

Enterprise identity platform with no-code orchestration for complex hybrid and air-gapped environments.

Editor's takePing Identity's FedRAMP High and DoD Impact Level 5 authorizations put it in a small tier of identity vendors trusted with the most sensitive government data. The DaVinci orchestration engine lets admins wire together identity services without custom code, and full feature parity across SaaS, on-prem and air-gapped deployments is rare among competitors. Workforce pricing starts at $3 per user monthly, but CIAM packages start near $20,000 a year, and reviewers flag a steep learning curve for administrators.

Auth0 is a developer-first identity platform with drop-in SSO backed by Okta.

Editor's takeAuth0 abstracts SAML and OIDC into a drop-in Universal Login, backed by Okta's infrastructure after a $6.5 billion acquisition. It secures more than 2.5 billion logins a month for over 7,000 customers. Cost is the real risk though, with one bill documented rising 15.5 times after modest user growth.

SSO platform connecting 6,000+ cloud and legacy apps, including Oracle EBS, with SOC 2 and HIPAA compliance.

Editor's takeminiOrange stands out for bridging modern cloud identity with legacy systems like Oracle EBS and PeopleSoft. At $1.50 per user a month, it undercuts market leaders like Okta by a wide margin. Niche integrations often need direct help though, and some users describe response times as inconsistent.

Passwordless SSO platform with RFID Tap & Go badges and deep Citrix and VMware support.

Editor's takeAuthX's RFID Tap & Go badge cuts login time from 14 seconds of typing to under 2, built for shared clinical and manufacturing workstations. Pricing starts at $2 per user monthly with MFA included, undercutting most enterprise SSO vendors. Its review base is smaller than Okta's though, and some users flag API documentation gaps.

Identity automation platform extending SSO and MFA to non-standard apps that lack native SAML support.

Editor's takeCerby uses robotic process automation to extend SSO, MFA, and password rotation to apps that don't support SAML or SCIM, like shared social media logins that IT teams typically can't secure at all. It is SOC 2 Type II certified and backed by a $40 million Series B round that included Okta Ventures and Salesforce Ventures. Pricing isn't public, but third-party estimates put a five-app deployment around $20,000 a year, and users report needing to sign in to Cerby every time they need access.

Smart SSO with FIPS 140-2 validated tokens and all-inclusive pricing covering tokens and support.

Editor's takeThales bundles tokens, authentication, and support into one all-inclusive license with no hidden per-token fees, a rarity in identity management pricing. Smart SSO applies context-based policies across a wide range of authentication methods, including FIPS 140-2 validated hardware and software tokens. Public G-Cloud listings price it around £13.94 per user, though setup can be tricky.

A mid-market identity and access management platform with a 6,000+ pre-built app catalog.

Editor's takeOneLogin publishes per-user pricing down to individual features, a rarity among enterprise identity vendors. Its 6,000-app catalog and HR-driven identity automation suit mid-market IT teams. A 2017 breach that exposed the ability to decrypt customer data remains a mark against its history, even after ISO 27001 and SOC 2 Type 2 certification since.

SSO tied to device compliance and endpoint management, with automated local admin password rotation.

Editor's takeScalefusion OneIdP ties login to device compliance, checking OS version, location, and management status before granting SSO access, a step beyond standard identity tools. Automated LAPS password rotation adds a security layer many providers require a separate product to cover. New administrators consistently report a steep learning curve, and pricing for the standalone identity tiers is not public.
