Identity-Centric Zero Trust Architecture -- Okta Alternatives
Zero trust architecture assumes no implicit trust based on network location, instead verifying every access request based on identity, device health, context, and risk. Identity is the foundational pillar of zero trust — every access decision starts with authenticating and authorizing the user. These Okta alternatives provide the identity capabilities needed to implement zero trust, from continuous authentication to device trust verification and adaptive access policies.
Deploy a centralized identity platform as the authentication and authorization authority for all access requests. Every application, API, infrastructure component, and network resource should authenticate users through the identity platform rather than relying on network-level trust.
Enforce MFA for all users with phishing-resistant factors as the primary method. Deploy device trust verification to ensure only managed, compliant, and healthy devices can access resources. Block or quarantine non-compliant devices until remediated.
Create risk-based access policies that evaluate multiple signals for every access request: user identity, authentication strength, device compliance, network location, application sensitivity, and real-time risk score. Apply least-privilege access based on this continuous evaluation.
Move beyond point-in-time authentication to continuous access evaluation. Monitor for session anomalies, user risk changes, device compliance drift, and context changes that should trigger re-authentication or session termination. Implement token lifetime policies that force periodic re-evaluation.
Feed identity risk signals into your SIEM, XDR, and SOAR platforms for correlated threat detection. Connect identity events with endpoint, network, and application telemetry to detect identity-based attacks like credential theft, lateral movement, and privilege escalation.
Free tier included with M365 / P1 from $6/user/month / P2 from $9/user/month
The most comprehensive zero trust identity platform when combined with Microsoft Defender, Intune, and Sentinel. Conditional access policies evaluate identity, device compliance, location, risk level, and session context for every access request, with continuous access evaluation for real-time policy enforcement.

Identity is the foundational pillar of zero trust, but a complete zero trust architecture also requires device trust (MDM/EDR), network segmentation (ZTNA/microsegmentation), application-level authorization, and continuous monitoring (SIEM/XDR). An identity platform like Okta, Entra ID, or Duo provides the authentication and access policy layer, but you need complementary security controls for device health, network access, and threat detection. Identity is where zero trust starts, not where it ends.
Microsoft's zero trust approach is deeply integrated across its entire security ecosystem — Entra ID for identity, Intune for device compliance, Defender for threat signals, and Sentinel for monitoring — providing a unified signal pipeline. Okta's zero trust approach is vendor-neutral, using integration partnerships with CrowdStrike, Palo Alto Networks, Zscaler, and others to collect device and network signals. Microsoft's approach is more turnkey for Microsoft shops; Okta's approach provides more flexibility for multi-vendor environments.
Duo provides a practical zero trust starting point by verifying user identity (MFA) and device trust (health checks) at every authentication. For organizations early in their zero trust journey, Duo delivers immediate value without requiring a full IAM platform migration. However, comprehensive zero trust eventually requires centralized identity governance, automated provisioning, and conditional access across all applications — capabilities that require a full IAM platform like Okta or Entra ID.
Identity governance ensures that users only have the access they need (least privilege) and that access is regularly reviewed and certified. In a zero trust model, excessive permissions are a critical risk — if an attacker compromises a user with broad access, the blast radius is large. Identity governance features like access reviews, entitlement management, and privilege access management reduce standing privileges. Okta Identity Governance and Entra ID P2 provide these capabilities; simpler platforms like Duo and JumpCloud do not.
