Introduction Global competition, shrinking IT budgets, ever-changing IT-business landscape and daunting complexity for IT monitoring and management. These are just a few of the problems Managed Service Providers (MSP) are facing today. UK-based Redstone is no different. As a leading network-based end-to-end managed services, infrastructure and technology provider it is responsible for the IT infrastructure of many of the country’s leading organizations, and it is not an easy task says Larry Dutton, Product Manager for Redstone’s managed services.

How to evaluate virtual firewalls

Dave Shackleford As their virtualized infrastructure grows, many organizations feel the need to adapt and extend existing physical network security tools to provide greater visibility and functionality in these environments. Virtual firewalls are one of the leading virtual security products available today, and there are quite a few to choose from; Check Point has a Virtual Edition (VE) of its VPN-1 firewall, and Cisco is about to offer a virtual gateway product that emulates its ASA line of firewalls fairly closely. Juniper has a more purpose-built Virtual Gateway (the vGW line) that is derived from its Altor Networks acquisition, and Catbird and Reflex Systems also have virtual firewall products and capabilities. So what do you look for when evaluating virtual firewall technology?Virtual firewalls: management and scalabilityBefore digging into the specifics of virtual firewalls, it's important to determine whether you really need one or not. Very small virtualization deployments…

Do you need virtual firewalls? What to consider first

John Burke, Contributor The size of the virtual hole in enterprise security is daunting. Virtual firewalls may be a solution, but there are many factors to consider first.What are virtual firewalls?Virtual firewalls are virtual appliances that re-create the functions of a physical firewall. They run inside the same virtual environments as the workloads they protect. Because they sit inside the virtual environment, they apply policy to traffic that is invisible to the physical network, securing it without negating the agility that virtualization brings. They don't necessarily care whether the virtual machines (VMs) are in the data center or floating up to an Infrastructure as a Service (IaaS) environment.Why the need for virtual firewalls?Currently more than 97% of companies virtualize servers, and more than 53% of the workloads running in the data center are on virtual servers. During the conversion from physical to virtual, security structures between servers on the physical netw…
