Cloud Firewalling brings about hypervisor-specific optimisations, resulting in far greater performance at significantly reduced expenditure.

The built-in high availability of the CronoSphere platform extends to NSX, so customers can be assured of round-the-clock protection and peace of mind against hardware failure.

Compare the performance of our NSX firewalling against popular Cisco Firewalls:

ASA 5505

This is offered by many hosting providers as a standard deployment entry level firewall. Whilst being relatively cheap, it is extremely limited in terms of performance and traffic handling.

ASA 5555-X

This firewall offers the same throughput as our VCNS offering, however it's a £10,000 appliance and you need to purchase two for high availability!

A comparison of performance between VCNS and hardware firewalls
  VMware NSX Cisco ASA 5505 Cisco ASA 5555-X
Firewall Performance 9.7 Gbit 150 Mbit 4 Gbit
Connections per second 50,000 4,000 50,000
Concurrent Sessions 1,000,000 25,000 1,000,000
IPsec VPN Throughput 2 Gbit 100 Mbit 700 Mbit

The dedicated Cisco devices are limited by physical network connections whereas the integrated VMware NSX firewalling runs at a hypervisor level and the 10 Gbit underlying network fabric.
