Systems and methods for providing private application access via client to client and server to client communication through a cloud-based system

The present disclosure includes, responsive to a request from a user device, performing a security check based on policy associated with the user device, wherein the policy includes setting related to content filtering and security; responsive to the security check, performing one of: directly allowing the request to the Internet based on the security check determining the request is allowed by the settings; directly blocking the request based on the security check determining the request is disallowed by the settings; and forwarding the request to a system for inline inspection based on the security check determining the request includes suspicious content, wherein responsive to the inline inspection, the request is one of allowed and blocked.

Cloud based security using DNS

Techniques for processing web probes for monitoring user experience including use of caching to prevent a surge of web probes on destination servers and for detecting web probe traffic. A method implemented by a connector includes intercepting a Hypertext Transfer Protocol Secure (HTTPS) web probe request to a server, identifying a cache hit associated with the request in a cache, generating a synthetic Hypertext Transfer Protocol (HTTP) response based on information from the identified cache hit, wherein the generated synthetic HTTP response includes an extension header containing collected statistics, and sending the synthetic HTTP response. The method can further include simulating a Secure Socket Layer (SSL) handshake to estimate SSL cost.

Systems and methods for reducing server load with HTTPS cache

Systems and methods for protecting sensitive mobile applications from attack include incorporating private application access software in a mobile application that operates on a user device to provide functionality to an end user, the functionality is separate from the private application access; deploying application connectors in front of a private application that is accessed by the mobile application; responsive to a request to access the private application, authenticating the end user through the mobile application; and, responsive to authentication, providing access to the private application through the mobile application via a plurality of secure tunnels. The application connectors are configured to only provide outbound connections, thereby protecting the private application from the attack. The request to access is received via a cloud-based system which is configured to drop any invalid request, thereby protecting the private application from the attack.
