By scoring the device and session at the moment credentials are submitted, not after. cside draws on 250+ browser, device, and network signals as the login page runs, detecting virtual machines, emulators, headless browsers, VPN and residential-proxy use, and devices linked to prior abuse, and returns a risk signal before the login is accepted. That lets teams step up with MFA, block, or review high-risk attempts that IP-based or password-only checks miss.
