CST VerdictShort answer
Startup and SMB engineering teams shipping products faster than they can build auth infrastructure from scratch should use Clerk. Pre-built, customizable UI components for signup, signin, and multi-tenant organization management eliminate weeks of security implementation work that typically introduces vulnerabilities. Skip this if you need enterprise SSO integrations, advanced threat detection beyond MFA, or compliance certifications beyond NIST Identity Management basics; Clerk handles authentication well but doesn't cover the detection and response functions larger organizations require. Security teams at startups and mid-market companies should choose OneLogin SmartFactor Authentication if they need MFA that actually adapts to risk instead of demanding the same friction from every user. The AI-driven risk scoring engine adjusts authentication factors dynamically based on login context, SMS, and device behavior, which means legitimate users stay unblocked while suspicious attempts get harder to bypass. Skip this if you're an enterprise with on-premises infrastructure requirements or need passwordless authentication as your primary goal; OneLogin's strength is conditional MFA, not replacing passwords entirely.
