Judicous Use of Advanced Technologies

Prioritize your applications and then decide which of them are mission critical and then secure those.
There is a risk/cost you always have to balance. You may not have the budge to secure every single application in your enterprise (some companies have thousands of apps).
The real question is: should we invest into looking deeper into the application and network layers, and the answer is a resounding yes.
It’s not so much about whether we should – but how do we do so in an intelligent relevant fashion that is cost effective? There is no point reinforcing the front door if your roof has a hole in it.
Maybe only your top three applications need this type of security. Maybe all your applications require this type of security? Prioritize!
