  • Remove security blind spots with nDA and gain visibility into encrypted traffic with full crypto support.
  • Deploy in a passive (out-of-band) or active (inline) tool-chaining configuration and place your security monitoring systems in a customizable virtual chain.
  • Reduce the port requirement by 50 percent, freeing up ports to connect more systems. Each system in the chain receives only the traffic of interest, increasing efficiency.
  • Purpose-built decryption acceleration hardware enables line rate processing free from bottlenecks.
  • High-performance packet processing resource provides hardware acceleration where the TLS and SSL decryption functions are performed to extend limits on throughput and prevent variable latency.
  • Comprehensive policy management functionality enables flexible policy-based decryption within your TLS and SSL decryption tools.
  • Maintain end-to-end security without degrading your security postures.
