A security event that is associated with one or more communication devices is detected. For example, the security event may be an unexpected change in data being sent from a communication device outside an enterprise. In response to detecting the security event, a Virtual Service Network (VSN) is created that isolates one or more communication devices that may pose a security risk. A corrective action to mitigate the security event is then implemented. For example, the corrective action may be to dynamically instantiate a firewall on the VSN that blocks the transfer of data from the communication device outside the enterprise. This allows an administrator to review the security event and take further action if necessary. Because the VSN with the firewall is created dynamically, the network remains secure while the security event is investigated.
