Remember this Network access control (NAC) includes methods to inspect clients for health, such as having up-to-date antivirus software. NAC can restrict access of unhealthy clients to a remediation network. You can use NAC for VPN clients and for internal clients. Permanent agents are installed on the clients. Dissolvable agents (sometimes called agentless) are not installed on the clients and are often used to inspect employee-owned mobile devices.
