Aculix is an identity and access management (IAM) vendor focused on passwordless and “invisible MFA” (continuous, risk-adaptive authentication) for workforce and customer access. Its platform combines passwordless authentication methods (including biometrics/FIDO-style approaches), device trust and posture signals (via endpoint/phone signals or agents), and a risk engine to reduce MFA prompts while increasing assurance, supporting deployment either as a full identity provider or as an MFA/risk layer on top of an existing SSO/IdP.
