A tool is disclosed for searching information redacted from electronic communications. The tool receives, based on input by a user into an interface of an electronic communication repository, a request to search through vaulted information, the vaulted information redacted from the electronic communication repository. The tool transmits an identity verification challenge to a device of the user and determines whether the identity verification challenge is successful. Responsive to determining that the identity verification challenge is successful, the tool searches the vaulted information for one or more files comprising a symbol input by the user, and generates, for display within the interface, identifiers corresponding to each of the one or more files.

One-shot challenge to search and access unredacted vaulted electronic communications

An example method comprises receiving, by a secure content system, an email from a sender to a recipient, scanning the contents of the email, evaluating the contents of the email based on a plurality of security rules, storing the sensitive data within a secure storage, generating a replacement email including a security link and not including at least the sensitive data, the security link providing a requester access to the sensitive data providing that a security function is satisfied, sending the replacement email including the security link to the recipient, receiving a request to access the sensitive data, the request being related to the security function challenging the requester using the security function, receiving, from the requester, a response to the security function, determining if the security function is satisfied by the response, and if the security function is satisfied, providing access to the sensitive data to the requester.

Protecting contents and accounts using scan operation

A system and a method are disclosed for verifying a suspicious electronic communication. To this end, a secure communications service may detect an electronic communication comprising an identifier of a purported originator of the electronic communication and an identifier of an intended recipient, and determine that an attribute of the electronic communication corresponds to a suspicious attribute. Responsively, the service may intercept the electronic communication and storing the electronic communication in purgatory memory, so as to prevent the electronic communication from being populated in a private repository of the intended recipient, transmit a verification message, and receive a reply to the verification message that verifies the authenticity of the electronic communication. In response to receiving the reply, the service may release the electronic communication from the purgatory memory, so as to cause the electronic communication to be populated in the private repository of the intended recipient.

Secure communications service for intercepting suspicious messages and performing backchannel verification thereon

A system and a method are disclosed for determining that a first electronic communication, received in a first private repository of a user, has been identified (e.g., flagged) as including a threat, and determining a probability that the first electronic communication includes the threat. In response to determining that the probability exceeds a threshold probability, the system monitors monitoring for a second electronic communication, received in a second private repository, that includes contents that match the contents of the first electronic communication. In response to, based on the monitoring, identification of the second electronic communication, the system generates a copy of the second electronic communication to an administrative private repository of an administrator, edits the copy to remove a portion that is likely to include the threat, inserts the copy of the second electronic communication to the second private repository, and deletes the second electronic communication from the second private repository.

Systems and methods for protecting contents and accounts

Techniques are provided for data exploration. An application is provided for execution on a client computer to display a plurality of data fields associated with one or more data sources, receive user input specifying a set of one or more graph parameters based on one or more selected data fields, generate a graph model, and transmit a continuous query request corresponding to the graph model. In response to receiving the continuous query request from the application, a continuous query is generated and stored in association with the graph model. The continuous query is periodically executed to generate a plurality of computed result sets over time by accessing the one or more data sources. A selected computed result set is provided to the application. The application is configured to render a graph in the graph rendering interface based on the selected computed result set.

Integrated data exploration, modeling and visualization

A system for pagination of data based on recorded URL requests, includes a data store comprising a computer readable medium storing a program of instructions for performing the pagination of data based on recorded URL requests; a processor that executes the program of instructions; a data segmentation module to receive a log of the URL requests, and to segment the log for a specific source; a referral tree construction module to construct a referral tree for the specific source based on the segmented log and HTTP referrer fields associated with the log; a tree enhancement module to enhance the referral tree based on site-specific rules; a signal computation module to perform signal computation on a plurality of nodes associated with the enhanced referral tree; a classification module to identify each of the plurality of nodes subsequent to the signal computation is performed on the enhanced referral tree; and a page construction module to construct a web page based on the enhanced referral tree subsequent to the classification module identifying the plurality of nodes.
