Isolating suspicious email links is described. An email security service receives an email that includes a link that refers to an external resource. A first suspicious link determination is performed to determine whether the link is suspicious. If the link is suspicious, the link is rewritten to refer to the email security and the email is delivered to the recipient. A request from a client device is received responsive to the link being opened. A second suspicious link determination is performed to determine whether the link is suspicious. If the link is suspicious, an interstitial page is transmitted to the client device that includes an option that, when selected, causes the first link to be opened in a remote browser isolation session.

A method and system for responding to requests for network resources implemented in a cloud computing infrastructure are described. A proxy server responds to requests from client devices based on the state of the origin instances that serve the requested network resources. The proxy server modifies the state of the origin instance based on whether requests are received for the network resources. The proxy server receives from the client device, a first request for a network resource that is served by an origin server. The proxy server determines a state of the origin instance, where the state of the origin instance indicates whether the origin instance is executing on the cloud computing infrastructure. Upon receipt of the state of the origin instance, the proxy server determines based on the received state, a response to be transmitted to the client device.
