  • Publication number: 20210390486
    Abstract: Described embodiments provide systems, methods and computer implemented instructions for prioritizing sequential application tasks. A system receives, from an application, a sequence of tasks to be performed by users using clients. The system identifies a first user to perform a first task in the sequence of tasks, and a second user to perform a second task in the sequence of tasks that is subsequent to the first task. The system determines the state of a first client of the first user and a state of a second client of the second user. The system establishes a rank for the first task based on the states of the first client and the second client. The system provides, to the first client, the rank for the first task and the state of the second client. The system generates a graphical user interface indicating the rank and state of the second client.

  • Publication number: 20210328999
    Abstract: A technique utilizes a security heat map associated with a geographic region. The technique involves receiving, by a server, current heat scores for one or more endpoint devices located within the geographic region. The technique further involves providing, by the server, for areas within the geographic region, respective aggregate heat scores based on the current heat scores for the one or more endpoint devices. The technique further involves, based on the respective aggregate heat scores for the areas within the geographic region, generating, by the server, a security heat map defining one or more security zones within the geographic region. The technique further involves imposing, by the server, security policies on the one or more endpoint devices based on the security heat map.

  • Publication number: 20210303269
    Abstract: A method for generating microapp recommendations comprises receiving observational data that characterizes interactions between users and applications. The method further comprises defining a set of correlation trees based on the received observational data. Each correlation tree in the set represents a sequence of interactions between one of the users and one or more of the applications. The set includes a first quantity of correlation trees. The method further comprises identifying a subset of similar correlation trees, each of which is included in the set. The subset includes a second quantity of correlation trees that is less than the first quantity. The method further comprises making a determination that the second quantity is greater than a threshold quantity. The method further comprises, in response to making the determination, generating a microapp recommendation based on the sequence of interactions represented by a correlation tree that is representative of the subset.

  • Patent number: 11074338
    Abstract: A technique for securely rendering content downloaded over a network includes parsing a downloaded web page into a DOM (Document Object Model) tree and splitting the DOM tree into multiple DOM instances, where each DOM instance is dedicated to a respective type of web content. The technique processes each DOM instance using a respective render engine, which implements the security policy on the respective type of web content by blocking or altering content, and/or by limiting functionality that may be used in connection with the content.

  • Publication number: 20210201175
    Abstract: Methods and systems are described for prioritizing notifications based on user responses. The system may include determining a first score indicative of a first relevance of a notification to a first user at a first client device. The first score is determined based on at least metadata characterizing the notification. The notification is prioritized for the first user based on at least the first score. The notification is presented at the first client device based on at least the prioritization for the first user. A second score is determined that is indicative of a second relevance of the notification to a second user at a second client device. The second score is determined based on at least a response to the notification from the first client device.
