System Architecture
In our solution server part is either SearchInform NetworkSniffer or EndpointSniffer data interception platform, and client applications used to work with the database and make data breach investigations.
Single search-analytical engine allows using all of the above-mentioned search possibilities in full.
Up to date DLP systems have a client-server architecture.
Network traffic Endpoint
Mirror switch Agent

IMHTTP Mail
SearchInform EndpointSniffer
is a platform that uses agents installed on user workstations
to intercept traffic.
The main advantage of IMSniffer and MailSniffer working on EndpointSniffer platform is high failure tolerance (data is intercepted even if servers are not available). Interception of data transmitted over secure protocols is also supported.
