CST VerdictBased on our analysis of core features, integrations, company size fit, deployment model, here is our conclusion:
Security teams defending against deepfake and AI-impersonation attacks in video conferencing will find RealityCheck's device-bound passkey model genuinely difficult to bypass, since authentication is cryptographically tied to the endpoint itself rather than just the user account. The tool covers NIST PR.AA and DE.CM strongly, meaning it locks down access at the authentication layer while maintaining continuous visibility into device posture and participant risk signals. Skip this if your organization rarely uses video calls for sensitive transactions or if you need passwordless auth that works across contractor devices you don't control; RealityCheck's strength is enforcing device compliance alongside identity verification, which creates friction for unmanaged endpoints.
