Attackers target data used by a variety of custom and commercial applications. Signature-only detection products can provide only a one-dimensional - and sometimes incorrect - response. Only Cisco uses broad network context through every stage of analysis, including passive OS fingerprinting, evasion techniques, and attack state across signatures, as well as - an industry first - attacker identity, location, and behavior. These state of the art techniques protect infrastructure and applications from Advanced Persistent Threats (APTs) and other sophisticated attacks for superior security protection.
