NETSCOUT nGenius Decryption Appliance vs Radiant Agentic AI: Side-by-Side Comparison (2026)

Short answer

Mid-market and enterprise security teams that need visibility into encrypted traffic at scale should build around nGenius Decryption Appliance; it's one of the few appliances that handles 40 Gbps bidirectional decryption without choking your ops budget or port density. Hardware acceleration and policy-based key management keep encrypted packet inspection from becoming a bottleneck that derails your detection pipeline. Skip this if your threat model doesn't require continuous monitoring of TLS/SSH sessions or if you're locked into cloud-native deployments where on-premises decryption infrastructure doesn't fit. Security teams drowning in alert volume need Radiant Agentic AI because its AI triage actually closes the investigation loop with one-click executable response, not just prioritization theater. The platform covers 100 percent of alerts across email, endpoint, identity, network, and cloud with full reasoning transparency, so you're not trusting a black box to kill your incidents. Skip this if your organization needs heavy forensics and recovery workflows; Radiant prioritizes speed through detection and mitigation over the deep post-incident analysis required for complex breach investigations.
