8 Best Duo Security Alternatives & Competitors (2026)

CyberArk specializes in privileged access management with vault-based credential storage and session isolation for enterprise environments. It offers strong compliance tooling and discovery of privileged accounts but relies on standing privileges and secrets management that Teleport eliminates through cryptographic identity and ephemeral access. Organizations with heavy regulatory needs may prefer CyberArk's mature vault features, while those seeking zero-standing-privilege models and AI agent governance often migrate toward Teleport for simpler infrastructure access.

HashiCorp Vault provides secrets management, dynamic credentials, and identity-based access for cloud infrastructure. It excels at brokering short-lived tokens yet still centers on a secrets engine rather than Teleport's hardware-rooted cryptographic identity for every human, machine, and AI actor. Teams already invested in the HashiCorp ecosystem may retain Vault for application secrets while adopting Teleport to unify infrastructure access and remove VPN complexity.

Okta delivers workforce identity and SSO across applications with strong MFA and lifecycle management. While it integrates with infrastructure tools, it lacks Teleport's native zero-trust access to servers, Kubernetes, and databases without additional proxies. Companies using Okta for employee authentication often layer Teleport on top to extend the same identity model to infrastructure with ephemeral privileges and full session recording.

Tailscale creates mesh VPNs using WireGuard for simple private networking between machines. It reduces some access friction but still grants broad network reach rather than Teleport's just-in-time, identity-centric permissions with cryptographic attestation. Teams wanting lightweight connectivity may start with Tailscale, yet those needing PAM-grade auditing and AI workload controls typically evaluate Teleport for deeper governance.

StrongDM offers proxy-based access to databases, servers, and clouds with policy-driven controls and session recording. Its architecture centralizes traffic through gateways, contrasting Teleport's direct cryptographic identity approach that avoids shared infrastructure. Organizations prioritizing proxy simplicity may choose StrongDM, while those targeting minimal attack surface and hardware-rooted identity often select Teleport.

BeyondTrust provides privileged access management with password rotation, endpoint privilege management, and remote access tools. It emphasizes credential vaulting and analytics, differing from Teleport's elimination of credentials via ephemeral, hardware-backed privileges. Enterprises with legacy Windows-heavy estates may retain BeyondTrust modules while adopting Teleport for Linux and cloud-native infrastructure.
