We live in a world where our expectations of services provided by business are continuously expanding. I am certainly guilty of unreasonably high expectations at times when it comes to resources and services not performing well, or being unavailable when I need them. These challenges can seem trivial, but the impact on consumers can lead to detrimental effect. With a digital world of information sharing at our finger tips, and with the exponential growth of online opinion even just a basic outage can have a large impact on any organisations brand. 

A trend hot in the market right now is agility and the positive impact this can have on competitive advantage. In my experience however, although we talk about agile development, and automation the reality is that large parts of our core business applications are legacy and running in high risk, fragile environments. When we introduce security into the mix, and we consider an effective security control for vulnerable applications segmentation is top of the list. The reality is that segmentation is hard, especially when considering the fragility of the network architecture.

Why is Segmentation so hard? What my customers and partners tell me is;

"If you can't see something, you can't understand it. If you can't understand it, you can't control it. If you can't control it, you can't improve it!"

Illumio de-couples Security Segmentation from the network meaning that we can make security focussed decisions without impacting network architecture. The application dependency Map takes an application centric view of the dependencies that an application has and allows us to build effective Security policy without impacting uptime, and without impacting the business. 

This paradigm shift not only allows us to support legacy applications in a safe manner, but also empowers organisations to plan for the future and benefit from agile application development, devops and orchestration.
