Systems and methods for transacting over a network. A first agent operating on a first computing system is operable to transact on behalf of a first entity. The first agent transacts with a second agent operating on a second computing system for a first cryptographically verifiable credential, transmits the first cryptographically verifiable credential to a third agent, and transacts with the third agent based on the first cryptographically verifiable credential for a second cryptographically verifiable credential to facilitate transacting with a fourth agent for a service. The second agent is operable to receive telemetry data of the first computing system which is configured to monitor the telemetry data, determine an assessment of the first entity based on the telemetry data, generate the first cryptographically verifiable credential based on the assessment of the first entity by the second agent, and transmit the first cryptographically verifiable credential to the first agent.

Systems and methods for transacting over a network. A first agent and a second agent are provided. The second agent is operable to transact with a third agent for use of a service, the third agent enabled to communicate with a fourth agent. The first agent is operable to communicate with the second agent to facilitate the transacting by the second agent with the third agent for the use of the service. The first agent is further operable to communicate with the fourth agent to facilitate the transacting by the second agent with the third agent for the use of the service.

A malware classification system includes a first machine-learning model trained based on malware from a first plurality of prior time periods to predict malware in a first subsequent time period subsequent to the first plurality of prior time periods, and a second machine-learning model is trained based on malware from a second plurality of prior time periods offset by at least some time from the plurality of time periods used to train the first machine-learning model to predict malware in a second subsequent time period subsequent to the second plurality of prior time periods. The trained first and second machine-learning models are used to predict malware in a future time period, and a classifier is trained using the malware from a plurality of the prior time periods and predicted malware from a future time period to train the classifier to identify and/or classify malware.

Systems and methods for transacting over a network. A first agent and a second agent are provided. The second agent is operable to transact with a third agent for use of a network-enabled service based on a first transaction policy from a fourth agent, the third agent enabled to communicate with a fifth agent. The first agent is operable to communicate with the second agent to facilitate the transacting by the second agent with the third agent for the use of the network-enabled service based on the first transaction policy and communicate with the fifth agent to facilitate the transacting by the second agent with the third agent for the use of the network-enabled service.

Systems and methods enable a notification based on determining a particular electronic message is associated with a particular cluster of electronic messages. A plurality of electronic messages from a first plurality of accounts directed to a second plurality of accounts over a network are received. The plurality of electronic messages are compared to determine a plurality of clusters of electronic messages. A particular electronic message is received from a first particular account directed to a second particular account. The particular electronic message is compared to the plurality of clusters of electronic messages to determine that the particular electronic message is associated with a particular cluster of the plurality of clusters of electronic messages. A notification is provided based on the determining that the particular electronic message is associated with the particular cluster of the plurality of clusters of electronic messages.

Systems and methods for transacting over a network is provided. The system includes a first agent and second agent. The first agent is operable to receive from a third agent a transaction code associated with one or more credential types required to apply the transaction code or with one or more credential claim types required to apply the transaction code, transmit the transaction code to the second agent, and receive from the second agent a digitally signed transaction, a first verifiable proof, and the transaction code. The first agent is further operable to transmit to a fourth agent a second verifiable proof based on the first verifiable proof and the transaction code, receive from the fourth agent an unlock signature for a locked credential including one or more credential claims, and transmit the unlock signature to the second agent.

The second agent is operable to transact with a third agent for use of a service, the third agent enabled to communicate with a fourth agent. The first agent is operable to communicate with the second agent to facilitate the transacting by the second agent with the third agent for the use of the service. The first agent is further operable to communicate with the fourth agent to facilitate the transacting by the second agent with the third agent for the use of the service.

Systems and methods for transacting over a network enable transacting on behalf of a first entity at a plurality of first network locations based on one or more first cryptographically verifiable credentials for a plurality of first network-enabled services. One or more assessments of the first entity are determined based on the transacting on behalf of the first entity at the plurality of first network locations based on the one or more first cryptographically verifiable credentials. One or more second cryptographically verifiable credentials are generated as one or more digitally signed credentials based on the one or more assessments of the first entity. The systems and methods further enable transacting on behalf of the first entity at one or more second network locations based on the one or more second cryptographically verifiable credentials for a second network-enabled service.

A method of managing access to a network destination. The method includes establishing a first network zone for a user, the first network zone including a plurality of network destinations. The first network zone is monitored and one or more changes in the first network zone are determined. A first network destination in the first network zone is analyzed responsive to determining the one or more changes in the first network zone to determine a first threat. An attempt by the user to access the first network destination is detected, and access by the user to the first network destination is restricted based on the determining the first threat.

A computing threat detection rule method and system for performing the method. The method includes determining identifiers for data points. One or more terms for each of the data points are determined to determine terms respectively associated with the identifiers. Collections of identifiers respectively associated with the terms are determined, the number of identifiers in each of the collections of identifiers limited to a threshold number. Conditions of a rule are determined. The conditions of the rule are compared to the terms to determine matching terms respectively associated with corresponding collections of identifiers. An intersection of the corresponding collections of identifiers is determined, and a number of the data points covered by the rule is determined based on the intersection of the corresponding collections of identifiers. A transmission is performed based on the number of the data points covered by the rule.
