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. Enterprise and mid-market organizations running on-premises infrastructure will get the most from RSA SecurID because it's built to integrate deeply with legacy Windows and Active Directory environments without ripping out existing systems. The SecurID Hardware Appliance deploys in days rather than weeks, and support for multiple authentication protocols means you're not forced into a cloud-first architecture. Skip this if your organization is cloud-native or standardizing on passwordless authentication across all services; SecurID's strength in hybrid failover comes with operational overhead that pure cloud MFA vendors have already eliminated.
