- 1. NetFlow Analyzer helped a leading bank to solve mysteries on their network.! Case study!
- 2. Company profile! Location:! ! ! Industry:! ! ! Number of branches:! ! ! Services:! ! ! ! Network infrastructure:! Indonesia! ! ! Banking services! ! ! 3 and over 10,000+ users! ! ! Internet banking, retail banking, ! Cash management! ! ! Monitored 20,000 interfaces ! including routers, switches & ! firewalls !
- 3. • Assess immediate and future bandwidth needs for smooth functioning of its branches, spread across different locations.! • Provide high priority to their critical business applications so that they are up and accessible all the time.! • Handle huge risk of data of their 1000+ users and prevent network from security threats and DDoS attacks.! • Identify and troubleshoot network issues faster before affecting end- users.! ! Challenges!
- 4. Looking for network visibility of their 3 branches with around 20,000 interfaces spread across all branches.! Company’s need!
- 5. • Helps to know the top talkers in the network for effective bandwidth usage.! • Monitoring of site links and notify if there is an issue at any of the branches. ! • Helps to assess long-term usage trends on its network devices.! • Shape QoS policies to meet bandwidth need.! • Monitor network behavior for any anomalies or attacks.! NetFlow Analyzer capabilities! “NetFlow Analyzer provides real-time visibility into our network’s bandwidth and prevent it from various network vulnerabilities .” !
- 6. Customize dashboard for quick view on top talkers. !
- 7. Monitor traffic at each site to check for bandwidth spikes. !
- 8. Monitor if business critical apps are accessible from all sites.!
- 9. Drillable conversation page to know which IP, application & protocol are consuming bandwidth.!
