Security Intelligence
💡 Network Telescope and Darknet Monitoring
Network telescopes monitor large blocks of unused IP address space. Since no legitimate traffic should reach these addresses, all observed traffic represents scanning, backscatter from spoofed attacks, or misconfiguration — providing pure signal for threat analysis.
💡 State-Sponsored Cyber Operations
Nation-state actors conduct sophisticated campaigns for espionage, sabotage, and influence operations. Their resources exceed typical criminal organizations, enabling zero-day exploitation, long-term persistent access, and attacks on critical infrastructure.
