IBM Cloud Identity

IBM Cloud Identity competes in the fast-growing Identity as a Service (IDaaS) segment of Identity and Access Management, which has evolved from web-centric beginnings into a mature, cloud-delivered way to provide IAM across application delivery models. Growth is driven by organizations seeking faster time-to-value than on-premises IAM, extending controls across expanding SaaS portfolios, reducing internal IAM cost and effort, and minimizing failures in project delivery and ongoing operations. Regulatory pressure such as GDPR, with fines up to 4% of global turnover for consumer data loss, further accelerates adoption as more data and applications move to the cloud and exposure increases when relying only on traditional IAM.

Hybrid IT—mixing public/private cloud and on-premises systems—adds complexity, including unsanctioned app usage and shared security responsibility across providers, while GDPR still places accountability on the data controller. Many cloud breaches stem from customer misconfigurations: weak or missing access controls and poorly protected credentials are especially risky because cloud services are internet-accessible. Traditional centralized IAM workflows for onboarding, job changes, auditing, and governance often don’t extend cleanly to cloud services, and CASBs are only a partial solution; access controls must be set within each sanctioned service and integrated with existing processes. IDaaS must also handle challenging hybrid connectivity to legacy web apps and provisioning, while remaining usable by line-of-business managers and everyday employees to reduce dependency on scarce security specialists.

IBM Cloud Identity is a subscription IDaaS platform emphasizing intuitive UX, rapid application onboarding, SSO, and configurable MFA, with broad integration via APIs and connectors. It can integrate with IBM Security Access Manager for granular legacy authorization, auditing, and reverse proxy connectivity, and with QRadar and MaaS360 for SIEM and mobile management. It supports OIDC, SAML-based social identity linking, OAuth delegated administration and “OAuth as a Service,” risk-adaptive MFA via Trusteer add-on, and developer enablement via APIs and a built-in GitHub portal. Key challenges include limited reporting depth, weaker out-of-the-box IGA, reliance on additional IBM components for hybrid AM/IGA, and higher complexity/cost for CIAM.

• The IDaaS market has been one of the fastest-growing segments of IAM.
• GDPR can fine organizations up to 4% of a company’s global turnover for loss of consumer data.
• Security responsibility in hybrid IT environments is often shared between the customer and the cloud service provider.
• Many security breaches in cloud environments originate from customer failures rather than provider controls.
• Incorrect or missing access controls and poorly protected credentials are major risks because cloud services are inherently open to the internet.
• IBM Cloud Identity provides cloud-delivered SSO and configurable multi-factor authentication.
• IBM Cloud Identity can integrate with IBM Security Access Manager for granular authorization control and can use it as a reverse proxy for on-premises resources.
• IBM Cloud Identity integrates out of the box with IBM QRadar for SIEM use cases.
• IBM Cloud Identity supports SSO to SaaS applications using OIDC and delegated administration flows using OAuth.
• SAML linking is enabled for Facebook, Google, LinkedIn, Twitter, and Yahoo.

• “Another driver for IDaaS adoption is stringent data governance laws such as GDPR (General Data Protection Regulation) which punish organizations financially for loss of consumer data.”
• “With more data and applications in the cloud, the potential for data loss is increased if organizations rely on traditional IAM solutions only.”
• “Most cloud service providers do implement strong security controls and consequently many security breaches originate from failures by the customer.”
• “Since cloud services are inherently open to the internet, incorrect or missing access controls and poorly protected credentials are a major risk.”
• “Supporting hybrid IT environments is among the main challenges for IDaaS, across all areas.”
• “As well as being compatible with complex operating environments, IDaaS must be accessible to regular employees and not just IT security professionals.”
• “Access to single applications is just a small part of the complex data interactions that comprise the modern workplace.”
• “The right IDaaS tool configured and deployed correctly to run the widest number of enterprise applications, on premises or cloud, can make a significant difference to workplace productivity.”
• “IBM Cloud Identity possesses a rich set of easy to use APIs and built-in connectors for faster onboarding of applications.”
• “While Cloud Identity works well as an access management tool, it does less well as a Identity Governance and Administration (IGA) tool out of the box.”
