Abstract: A network device is configured to receive network traffic associated with an application executing on a user device; identify, based on the network traffic, an application identifier associated with the application; determine whether the application identifier matches one of a set of application identifiers stored by the network device; identify a policy based on the application identifier when the application identifier matches one of the set of application identifiers; and apply the policy to the network traffic associated with the application. The policy may be obtained from another network device, in communication with the network device, when the application identifier does not match one of the set of application identifiers.

Abstract: A computing device may receive content from a content source. The content may include software code that is executable by a web browser, and may be directed to another computing device. The computing device may inject security content into the content. The security content may include software instructions to enable the web browser to detect malicious software content within the content. The computing device may communicate the content to the other computing device.

Abstract: A method is disclosed for reproxying connections. According to one aspect, a first connection is established between a client and a proxy device. A second connection is established between the proxy device and a server. The first connection comprises a first endpoint at the client and a second endpoint at the proxy device. The second connection comprises a third endpoint at the proxy device and a fourth endpoint at the server. The first and second connections are unproxied by dissolving the second and third endpoints while maintaining the first and fourth endpoints. After the connections have been unproxied, a packet is received at the proxy device. In response, the first and second connections are reproxied by creating fifth and sixth endpoints at the proxy device, so that the first connection comprises the fifth endpoint and the second connection comprises the sixth endpoint.
