netsentryx — Uma plataforma de monitorização de rede orientada a eventos que realiza captura de pacotes em tempo real (Npcap), análise de tráfego de baixa latência e deteção de ameaças não supervisionada utilizando um Autoencoder PyTorch, suportada por um motor de alertas assíncrono multicanal. | Kitploit
