Embodiments of the technology described herein identify and mitigate phishing attempts by analyzing user input using a client-side proxy component and a proxy server. Embodiments disclosed herein provide systems, methods, and computer-storage media for employing proxy server capabilities in conjunction with a snapshot capturing an image or video recording of a target action input by a user into a software application. Certain embodiments disclosed herein employ proxy server capabilities to capture a snapshot and/or screen recording based on a user authorization or approval. For example, the proxy server proactively captures the snapshot or screen recording prior to, during, and after the user performing a target action. From the snapshot, certain embodiments extract snapshot features or determine enriched-contextual event data that is used to perform a mitigation action, generate a security mitigation score, or update an administrator portal activity log for an authorized administrator.

Snapshot for activity detection and threat analysis

Methods, systems and computer program products are provided for multi-layer, browser-based context emulation detection, which may be implemented by a proxy for browsers. A policy may be enforced against requests if a request context indicates a restricted context. Context may be detected and indicated in a response header and body based on one or more context detection/indication rules. Context may be indicated by marking or not marking resources indicated in responses. Code may be injected to cause the client web browser to indicate context. A response may be forwarded to the client with a response header context, a response body context, and/or injected code, which a client browser may process to generate a request with one or more indications of request context.

Multi-layer browser-based context emulation detection

Automated and semi-automated document redaction technology is disclosed herein. In certain example embodiments, 'context-aware' redaction is provided. Automated techniques are used to identify a set of potentially sensitive item(s) within a document. The potentially sensitive item(s) are filtered based on contextual information, such an entity identifier (e.g. person identifier, person group identifier identifying a group of multiple people, organization identifier etc.), resulting in a filtered set of redaction candidate(s). The filtered redaction candidate(s) may, for example, be redacted from the document automatically, or outputted as suggestions in an assisted redaction tool, e.g. via a document redaction graphical user interface. Other example embodiments consider selective redaction when uploading and/or downloading documents via a proxy server, to prevent intended or unintended release of potentially sensitive information, e.g. in a web browsing context.

Detection and removal of predefined sensitive information types from electronic documents

According to examples, an apparatus may include a processor and a memory on which are stored machine-readable instructions that when executed by the processor, may cause the processor to obtain an encryption key from a user. The processor may identify session activity data during a proxy session of the user and may encrypt the identified session activity data using the encryption key obtained from the user. The processor may store the encrypted session activity data.

Encryption of proxy session activity data using user-provided encryption keys

Generally discussed herein are devices, systems, and methods for secure cloud application provisioning. A method can include, while providing access to the cloud application, receiving data indicating a first universal resource locator (URL) entered in a search bar of a web browser associated with the cloud application has changed to a second URL, determining whether the second URL has a valid certificate, and in response to determining the second URL is associated with the cloud application and a valid certificate for the second URL exists, providing resources for the second URL and the valid certificate to the web browser or in response to determining the second URL is not associated with the application, re-directing the web browser away from the proxy server.

Multi-layer navigation based security certificate checking

A computer-implemented method includes receiving, by a reverse proxy device, a session control template, and a client request directed to a service provider regarding an application. The method includes determining, by the reverse proxy device, whether the client request should be allowed or blocked based on the received session control template. If the reverse proxy device determines that the client request should be allowed, the client request is forwarded from the reverse proxy device to the service provider. If the reverse proxy device determines that the client request should be blocked, the client request is blocked from proceeding to the service provider.
