Methods and systems for assigning reputation to communications entities include collecting communications data from distributed agents, aggregating the communications data, analyzing the communications data and identifying relationships between communications entities based upon the communications data.

Multi-dimensional reputation scoring

Methods and systems for operation upon one or more data processors for detecting image spam by detecting an image and analyzing the content of the image to determine whether the incoming communication comprises an unwanted communication.

Detecting image spam

A system derives a reputation for a plurality of network addresses, the reputation of each network address determined by analyzing a plurality of high-level email features related to one or more emails originating from the network address. The plurality of high-level email features include domain registration analysis, hashed term frequency indexing, persistent communication, address age, correlation analysis, zombie detection, and hash vault matching.

Reputation management for network content classification

Computer-implemented systems and methods for identifying illegitimate messaging activity on a system using a network of sensors.

Systems and methods for identifying potentially malicious messages

Methods and systems for operation upon one or more data processors for assigning reputation to web-based entities based upon previously collected data.

Web reputation scoring

Methods and systems for operation upon one or more data processors for assigning a reputation to a messaging entity by analyzing the attributes of the entity, correlating the attributes with known attributes to define relationships between entities sharing attributes, and attributing a portion of the reputation of one related entity to the reputation of the other related entity.

Correlation and analysis of entity attributes

Methods and systems for operation upon one or more data processors to filter communications of users in accordance with content-based policy.
