authentik vs Cerby Automated Credential Management & SSO: Side-by-Side Comparison (2026)

Startups and SMBs that need SSO and MFA without vendor lock-in should run authentik; the open-source model means you own the codebase, avoid licensing creep as you scale, and can self-host or go hybrid without renegotiating contracts. It covers NIST PR.AA identity management and access control natively, and the built-in application proxy handles remote access to RDP, SSH, and VNC without bolting on a separate tool. Expect to staff more ops lift than a SaaS alternative; this is not the tool for teams wanting a hands-off managed identity service. Security teams managing sprawling SaaS estates with legacy apps that lack SAML or OIDC support should pick Cerby Automated Credential Management & SSO to eliminate manual credential hygiene without ripping out existing workflows. The platform automates password rotation, MFA enrollment, and session termination across non-standard applications while preserving your identity provider integration, addressing a real gap in NIST CSF 2.0 PR.AA coverage for organizations stuck between modern IAM and older tooling. Skip this if your stack is already SAML-native or if you need deep privileged access management for infrastructure; Cerby solves the SaaS credential problem, not PAM.
