  • Publication number: 20240007305
    Abstract: A node configured as any of a proxy, a Secure Web Gateway, and a Secure Internet Gateway is configured to perform steps of, responsive to establishing a connection with a user device having a user associated with a tenant and obtaining policy for the user, monitoring traffic between the user device and the Internet where the monitoring is at a middle location, inline between the user device and an endpoint; responsive to the traffic being encrypted as a tunnel, performing one or more operations to enable accessing the encrypted traffic; analyzing the traffic based on the policy, including at least checking for malicious traffic and Data Loss Prevention (DLP) for the tenant; and one of allowing, blocking, or limiting the traffic based on the analyzing.

  • Patent number: 11394563
    Abstract: Systems and methods include, in a node operating as a snooping proxy, monitoring traffic between a user device and the Internet; detecting and monitoring a handshake between the user device and an endpoint for determining keys associated with encryption between the user device and the endpoint; monitoring encrypted traffic between the user device and the endpoint subsequent to the handshake based on the keys; and performing one or more security functions on the encrypted traffic based on the monitoring. The node can be part of a cloud-based security system and configured inline between the user device and the endpoint.
