How to evaluate Identity & Access Management

This is how the CIOPages Research Team evaluates this category. It is not an assessment of SPIRE. It comes from our Identity & Access Management (IAM) buyer guide.

30%

Authentication & SSO

Phishing-resistant MFA and passkeys/FIDO2 as first-class methods, device-bound credentials, SAML/OIDC/WS-Fed breadth, adaptive and risk-based step-up, device trust, session management and continuous evaluation, and graceful fallback and recovery that does not become the help-desk attack vector

20%

Lifecycle & Provisioning

HR-driven joiner-mover-leaver automation, SCIM and LDAP provisioning, depth and maintenance of the application connector catalog, self-service access requests, fast and reliable deprovisioning, and handling of contractors, partners, and seasonal populations

15%

Directory & Hybrid Architecture

Universal/cloud directory, coexistence with on-prem Active Directory and LDAP, hybrid agents and write-back, multi-domain and multi-forest support, data residency options, and the resilience and blast radius of the directory as a revenue-critical dependency

15%

Identity Threat Detection & Response (ITDR)

Post-authentication risk evaluation, session and token-theft detection, anomaly and impossible-travel signals, identity security posture (dormant accounts, over-privilege, MFA gaps), and how cleanly signals flow to and from the SIEM/XDR and trigger automated response

10%

Machine & Agent Identity

Issuance of scoped, short-lived credentials for service accounts, workloads, and first-party APIs (OAuth client-credentials, workload identity federation), discovery and governance of non-human identities, secrets handling, and emerging support for AI-agent identities acting on a user’s behalf

10%

Deployment, Integration & Commercial Fit

Pre-built connectors for your actual top applications (verified, not catalog-counted), migration tooling and coexistence, API and SDK quality, administrative usability, the pricing unit relative to your user and machine population, and the realism of support and professional services
