Cloud-based NAC offers flexibility, scalability, and ease of deployment, as it doesn't require on-site hardware or extensive maintenance. On-premise NAC systems can be more complex to manage and scale. Cloud-based NAC is more suitable for businesses with remote workforces and dynamic environments.

Cloud-based NAC provides centralized management, scalability, cost-effectiveness (with lower upfront costs), automatic updates, real-time monitoring, and ease of integration with other cloud-based services. It also enhances network security by enforcing access policies remotely and dynamically.

NAC can enforce policies based on the user, device type, location, and role, thereby ensuring that only trusted devices and users have access to company resources, reducing the attack surface. It can also help implement passwordless, certificate-based authentication, which greatly reduces the possibility of a breach via phishing or compromised credentials.

All sizes! Large businesses will appreciate cloud-based NAC’s ability to create a unified access control policy across all locations. Medium-sized businesses will benefit from a robust feature set without the typical complex deployment process. And small businesses where IT staff wear many hats will appreciate not spending their nights and weekends doing patches and upgrades. Everyone wins!
