  • Blocks any type of attacker, including zombie computers, compromised accounts, spammer accounts, and webmail spam.
  • Identifies the source, alerts the abuse/fraud detection team, and provides samples of unwanted traffic.
  • Includes multiple plugin options and is delivered via a comprehensive SDK (daemon or shared library).
  • Integrates easily into existing platforms, minimizing costs and time-to-market.
  • Uses low resources—Cyren’s uniquely small footprint fits any hardware or software environment without affecting performance.
