SecureW2 JoinNow

SecureW2 JoinNow helps you eliminate the risks of password-based authentication by transitioning your network to a more secure, certificate-based model. You can automate the entire onboarding process for BYOD, managed devices, and IoT hardware, ensuring every connection is encrypted and verified. By replacing vulnerable credentials with digital certificates, you effectively stop man-in-the-middle attacks and password-related help desk tickets.

The platform integrates with your existing identity providers like Google, Microsoft, and Okta to streamline deployment without replacing your current infrastructure. You can manage the full lifecycle of certificates through a centralized management portal, giving you total visibility into who and what is accessing your network. It is a practical solution for schools, enterprises, and government agencies looking to modernize their wireless security.
