3 We Are All Under Attack Cyber threats impact the security and economic viability of nations and businesses alike Manipulation Theft & Espionage Disruption 3

4 The Impact of Complex Cyber Threats Sophisticated Attacks With Specific High-Stakes Intent 49% of threats are customized for target environment 1 $1T/year private sector revenue loss from cyber espionage 2 5X increase in attacks against US Government 2006 to Compromise Is Not If, but When 59% of organizations believe they have been cyber threat targets 4 46% believe they are still highly vulnerable despite increased prevention investments 5 Customers Investing to Respond 52% invested in network anomaly analysis/detection 6 77% increase investment in security solutions in reaction to cyber threats 7 1 Verizon Data Breach Report; 2 US House Intelligence; 3 Cyber Market Forecast; 4 ESG APT Report; 5 7 ESG 4

5 Key Challenges: Complex Threat Visibility Breached, but How, Where and Who? Often very difficult to find Attacks are hidden by day-to-day operations Context is Critical No single system provides all data to decipher an attack Attacks can span devices, individuals, time, etc. Disparate Data sources Multiple data sources required identity, reputation, vulnerability, device type, etc. Analysts collect and assemble contextual information from a variety of sources 5

6 Leverage the Network for Threat Defense WHAT WHERE WHEN NetFlow Capable WHO HOW Devices Visibility, Context, and Control Internal Network VPN Use NetFlow Data to Extend Visibility to the Access Layer Access Layer Use NetFlow Data to Extend Visibility to the Unite Flow Data With Identity and Application for Context Unite Flow Data With Identity and Application for Context 6
