Abstract: Disclosed herein are computer-implemented methods and systems for forecasting security ratings for an entity. The methods and systems can include generating a plurality of simulated instantiations of a security scenario for the entity, in which the security scenario characterized by a plurality of security events associated with at least one event type. The methods and systems can further include determining a security rating for each instantiation of the plurality of instantiations; and generating a forecast cone based on the determined security ratings for the plurality of instantiations. In some examples, for each event type of the at least one event type, the methods and systems can include determining a rate, duration, and/or temporal placement of the security events associated with the event type over a forecasting period.

Abstract: A computer-implemented method is provided for comparing the security profile of a particular entity to peer entities. The method can include receiving, for a particular entity, (i) a value for at least one feature and (ii) a number of security records of one or more security risk types. The method can include determining peer entities based on the value of the features; obtaining, for each peer entity, a number of security records; and adjusting the number of peer security records based on the number of entity security records. The method can further include comparing, for one or more security risk types, the received number of security records for the particular entity to the respective adjusted number of security records for each peer entity; and comparing a security profile of the particular entity to security profiles of the population of peer entities based on the comparison for the security risk types.
