We are happy to announce the latest version of GREYCORTEX MENDEL. Version 2.8 includes three new important features: the first is the Event Collector. Released as part of v2.7 (a limited release), the Event Collector offers the opportunity to centrally monitor events from several remote GREYCORTEX MENDEL collectors. The second major new feature is the Correlation Engine. This tool correlates individual, less-serious events – which together may be indicative of attacks within the network, to more effectively alert security analysts. Finally, MENDEL 2.8 includes proxy pairing functionality which identifies source or destination addresses hidden by proxy servers, which will allow security analysts to better identify potential issues on the network and provide even greater visibility.
