Human identities have access to far more systems and data than their roles require. This widespread overprovisioning significantly increases the potential impact of compromised accounts.
The challenge becomes even greater when machine identities are included. The report found that machine identities now outnumber human identities 100 to 1, with AI agents accounting for 79 of those 109. As a result, the volume of identities and permissions that governance teams must manage is growing far faster than organizational headcount.
Managing this expanding access environment requires a structured approach to assigning permissions and enforcing policies. Identity governance and administration (IGA) provides that framework.
In this guide, we compare three leading IGA platforms to help you choose the one that best fits your organization’s governance requirements and operational reality.
Identity governance and administration manages identities and the access they hold. It helps ensure every user, application and non-human identity (NHI) has the right access for only as long as needed.
A modern IGA platform is expected to do several things well at the same time:
Identity Manager by One Identity is built to be the governance engine at the center of an organization's identity program. It gives authorized users access to the data and applications they need, and only what they need, whether systems run on premises, in the cloud or in a hybrid environment.
Hear from One Identity customers:
"We saw a dramatic increase in the productivity of IT staff when they started using the One Identity solution."
- Nathan Wiehe, Vice President of Identity and Security Services, EST Group
"The benefit of having features like recertification in Identity Manager is that we don't have to create them. It's just a matter of configuration instead of programming."
- Gert Heidema, Solution Architect, Identity & Access Management, global bank
SailPoint is a popular name in identity governance, and its AI-driven access recommendations and cloud governance features have made it a common choice for large enterprises.
It is a genuinely capable platform. The trade-off is that reaching that capability tends to require a long implementation and significant specialist investment, which is where many teams find Identity Manager by One Identity the more practical fit.
SailPoint's depth is real. But reviewers on independent sites consistently point to the time, cost and specialist effort it takes to reach and maintain that depth. The more turnkey approach of One Identity Manageris designed to reduce exactly that burden.
Saviynt markets itself as a converged, cloud-only multi-tenant platform that unifies identity governance, privileged access and application access controls.
It is a modern architecture and a reasonable option for organizations that want that convergence from one vendor.
The trade-off, based on independent reviews, is that the platform is harder to administer than its interface suggests, and reviewers also point to slow support and thin documentation.
These patterns show up repeatedly across independent reviews:
The table below summarizes how the three platforms compare across the capabilities that matter most when choosing an IGA solution.
Capability
Identity Manager
SailPoint
Saviynt
Architecture

Single-codebase convergence of IGA, PIM and access governance
Identity lifecycle and provisioning
Automated, with self-service request portal
Automated, AI-assisted application onboarding
Automated, entitlement-warehouse driven
Access certification and attestation
Granular, event-triggered, with Governance Heatmap View
AI-assisted peer-group recommendations
AI/ML-driven, warehouse-based risk context
AI-driven access intelligence
Natural-language compliance reporting, ITDR playbooks
Access recommendations, identity outliers
AI/ML entitlement risk scoring
Privileged access integration
Native, via Safeguard by One Identity
Limited, per independent reviews
Included, but reviewers call it incomplete
Deployment options
On-premises, hybrid, cloud and dedicated SaaS (Idetity Manager on Demand)
Cloud (Identity Security Cloud) and legacy on-premises
Cloud-native SaaS
Ease of deployment and administration
Turnkey connectors, generalist-friendly portal, on-prem support
Long, services-heavy, specialist-dependent per reviewers
Clean front end, complex back end per reviewers
Cost fit
Easier to right-size across enterprise and mid-market
High services cost on top of licensing, per independent estimates
Varies, licensing plus configuration effort
Identity governance priorities shift by sector, depending on which systems hold the most sensitive data and which regulators are watching. Below is how the three platforms line up against the specific demands of different industries.
IGA for financial services and bank organizations operate under strict access governance requirements, where auditors expect documented, tested evidence of who can reach financial systems and why.
The priorities here are SoD, need-to-know access restriction and detailed audit trails, supporting frameworks such as SOX and PCI DSS.
Identity governance solutions for healthcare organizations are designed to govern access to patient data, clinical applications and connected infrastructure, where standing access and unreviewed permissions can let a single compromised account spread quickly.
The priorities are role-appropriate access, regular recertification and audit controls, supporting HIPAA and frameworks such as SOC 2.
Manufacturing and energy environments span both IT and operational technology, where shared admin accounts and infrequently reviewed access can go unnoticed for long periods.
The priorities are least privilege enforcement, coverage across legacy and OT-adjacent systems, and strong audit trails, supporting standards such as NERC CIP.
Every enterprise has an IT director or a CISO responsible for selecting the suitable identity governance solution. Use this checklist to compare the three and decide which fits your environment.
SailPoint and Saviynt are both capable identity governance platforms with real strengths. SailPoint brings mature AI-driven recommendations for large enterprises that can absorb a long implementation. Saviynt offers a modern, converged architecture for organizations that want IGA and PAM from a single vendor.
For most organizations, though, Identity Manager by One Identity is the strongest overall choice because it delivers identity lifecycle management, access certification, role and entitlement governance, and privileged access oversight as one unified program, with a lighter implementation footprint and manageability that does not depend on a large team of specialists.
