Network traffic inspection is disclosed. An application executing on a client device as an operating system that uses a virtual private network (VPN) stack of the operating system intercepts a first IP packet. The application determines that a policy should be applied to the intercepted first IP packet. The policy is applied to the intercepted first IP packet.

Network traffic inspection

Techniques for inspecting network traffic are disclosed. An application executing as an operating system extension that uses a virtual private network (VPN) stack of the operating system intercepts an Internet protocol (IP) packet for delivery to a remote computer system. A determination is made of an alteration action to take in response to intercepting the packet. The determined action is taken.

A reverse TCP/IP stack infrastructure is disclosed. In an example use, an application executing on a client device as an operating system extension that uses a virtual private network stack of the operating system intercepts a first IP packet generated by a client program. The application determines that the first IP packet comprises a Transmission Control Protocol synchronize message and opens a socket to a destination Internet Protocol address and destination port. A synchronize acknowledgement is received. A packet to transmit to the client program is synthesized that includes a synchronize acknowledgment.

Reverse TCP/IP stack

Techniques for inspecting network traffic are disclosed. An application executing as an operating system extension that uses a virtual private network (VPN) stack of the operating system intercepts an Internet protocol (IP) packet for delivery to a remote computer system. A determination is made of an action to take in response to intercepting the packet. The determined action is taken.

An access proxy system is disclosed. A proxy server receives, from a client device, a request to access a protected resource. The protected resource represents a mapping between a user-facing domain and an internal domain that is only accessible from behind a set of one or more proxies that includes the proxy server. In response to receiving a grant of permission by an access policy engine, the proxy server proxies access to the protected resource using a mutual-TLS connection with the client device.

Access proxy platform

A mobile device application executing on a mobile device as an operating system extension that uses a virtual private network (VPN) stack of the operating system intercepts a first Internet protocol (IP) packet for delivery to a remote computer system. The application determines that the intercepted first IP packet is associated with sensitive information. In response creates a VPN tunnel between the remote computer system to securely send data from the mobile device to the remote computer system.

Techniques for inspecting network traffic are disclosed. An application executing as an operating system extension that uses a virtual private network (VPN) stack of the operating system intercepts an Internet protocol (IP) packet for delivery to a remote computer system. A determination is made, by the application, that the intercepted IP packet indicates a security threat. The intercepted IP packet is prevented from being delivered to the remote computer system based on the determination.

Systems and methods monitor a system including a remote desktop, a trusted mobile instance, and a delivery handler. The delivery handler can determine if the system is overloaded and to take the appropriate measures to maintain a negotiated minimal QoS and adapt as necessary when the conditions vary. Additionally, the systems and method can address security issues by separating privileges that are typically bundled together in conventional systems, and by applying isolation mechanisms to exposed areas of the system.
