I have NAC deplyed in OOB VGW and have version 4.8. Due to restricted internet policy, people are using internet through broadband devices. Is that
possible if NAC can block these broadband connections.
NAC agent can only posture-assess, and help with remediation, if needed. It can't enforce any policies, so if your clients for example use an air-card or connect through the internet through some other mechanism, the agent won't be helpful there.
