1Password Extended Access Management vs Exostar Managed Access Gateway (MAG): Side-by-Side Comparison (2026)

1Password Extended Access Management

Mid-market and enterprise security teams with identity sprawl across SaaS and on-premises systems should pick 1Password Extended Access Management for its ability to enforce least-privilege access without requiring directory infrastructure overhaul. The platform scores strongly on NIST PR.AA and DE.CM, meaning it detects unauthorized access attempts and anomalous behavior in real time rather than waiting for a breach to surface. Skip this if your organization runs a tightly controlled, single-directory environment where access is already audited; the tool's strength lies in managing messy, distributed identities where traditional PAM tools fall short.

Exostar Managed Access Gateway (MAG)

Mid-market and enterprise security teams managing third-party partner access across regulated supply chains will get the most from Exostar Managed Access Gateway because it handles the friction of federated identity at scale without forcing partners through your internal IAM infrastructure. The platform covers ITAR, DFARS, and NIST 800-171 compliance natively, and its pre-vetted network of 200,000 organizations cuts onboarding cycles from weeks to days. Skip this if your partner ecosystem is small or you need deep workforce IAM controls; MAG is purpose-built for B2B access governance, not employee identity management.
