Cisco Secure Network Analytics (Stealthwatch)

Cisco Secure Network Analytics, formerly known as Cisco Stealthwatch, is a comprehensive threat detection and response solution designed to provide deep visibility across an organisation’s network. It monitors on premises infrastructure, cloud environments, and remote connections by analysing network traffic and behavioural patterns in real time. Instead of relying solely on signature based detection, it establishes a baseline of normal network activity and applies advanced analytics and machine learning to identify anomalies such as ransomware activity, insider threats, lateral movement, or data exfiltration. Because it operates without requiring agents on every endpoint, it can leverage network telemetry like flow data to deliver broad coverage with minimal disruption. The platform can also analyse encrypted traffic metadata to detect hidden threats without decrypting content, which helps balance security and privacy. Security teams benefit from prioritised alerts, detailed context for investigations, and integration options with broader security orchestration and response tools. With flexible deployment models including physical, virtual, and cloud based options, Cisco Secure Network Analytics supports scalable, network wide monitoring that improves threat detection speed and strengthens overall security posture.
