The Dirty Secrets of Network Firewalls

Results of an independent survey of 2,700 IT Managers in 10 countries, in organizations of 100-5000 users.

Dirty Secret 1: Firewalls are failing to deliver the protection organizations need

  • 16 infected devices per month, on average
  • No. 1 desired firewall improvement is better protection

Dirty Secret 2: IT managers can’t tell you how 45% of their bandwidth is consumed

  • 45% network traffic is going unidentified.
  • This leads to multiple areas of concern, including security, productivity, accountability, legal liability and compliance, and ROI.

Dirty Secret 3: Ineffective firewalls are costing you time and money

  • 3.3 hours — average time taken to identify, isolate and remediate infected machines
  • 7 days — time lost every month fixing infected devices

What IT managers want from their firewalls:

  • 79% better protection
  • 85% better visibility
  • 99% automatic isolation of infected devices
