Email security that inspects intent, context and behavior - not just spam scores.
NXG combines a self-hosted email security gateway with a deep-inspection investigation lab for internal email protection, evidence-driven analysis and SOC/SIEM integration.
Modern email attacks are designed to look legitimate.
Low-volume phishing, impersonation, compromised-account abuse and context-aware social engineering can pass reputation checks and traditional spam scoring. NXG adds layered inspection and explainable security context.
